Precious metals trading company information system risk control concept


  The essence of electronic trading of precious metals is to rely on the information system electronic platform for trading, customers from online account opening, signing, deposit, trading, withdrawal, termination of all investment activities are concentrated in the operation of the information system electronic platform, so a safe and fast operating system will become the key to the long-term healthy and sustainable development of precious metals trading.

  Information System Risk Definition

  Information system risk refers to the existence or technical failure of the electronic information system, resulting in the interruption of the market, trading halts, bank transfer and other problems that do not guarantee the normal operation of the transaction, thus causing adverse losses to customers, the company’s economic and reputation loss risk due to the obligation to compensate. At the same time, there is also the risk that the technical defects of the software design will lead to errors in the calculation of investors’ transaction data and damage to investors’ property caused by data destruction.

  Information system construction and maintenance status

  Electronic trading of precious metals is a business model based on an information system platform. A stable, safe, convenient and efficient trading system platform is undoubtedly the most important concern of all market participants. The precious metals industry started late, and the level of information technology and trading system research and development is relatively backward, making all major trading centers nationwide develop and maintain their trading systems independently for a long period of time, so each precious metals trading company (member unit) does not pay enough attention to the compliance management of information systems.

  Precious metals trading companies generally do not set up special technical support departments, and there is a lot of randomness in the handling of abnormal problems that occur on the trading system platform, and there is no dedicated task, and there is often no one to track the course of events. At the same time, the trading system is constantly being updated and optimized, and there are new standards for the hardware, software and application systems of the company’s equipment, while the company does not have a special technical department and lacks relevant technical staff, so it is obviously unable to cope with the process of system operation and maintenance.

  Maintain a safe and robust information system

  1. Maintain the security and stability of the system hardware network

  In order to maintain a robust information trading system and give full play to the role of IT systems in supporting business operations, the technical department of the precious metals trading company must do a good job of managing hardware equipment, information security and network facilities and other infrastructure to avoid problems such as data and information transmission errors and system crashes that cause transactions to not proceed smoothly.

  System security. Ensure the standardization of interfacing with the trading center system, create a user permission approval system, enhance permission approval for major businesses prone to risk potential, prevent illegal authorization, and curb cross-access by incompatible positions. Make full use of network equipment, software technology and other security strategies, such as firewalls, intrusion scanning, and vulnerability detection, to strengthen network security and prevent network attacks, and take encryption measures for key data transmitted to ensure the security and accuracy of information.

  Daily management. The technical department needs to be designated to perform relevant management duties, participate in the transformation of various technical systems organized by the trading center, testing work and technical training meetings held, and submit relevant reports, coordinate the handling of technical incidents that occur, etc. The company should formulate system emergency plans and revise them in a timely manner as needed to ensure that emergency measures can be implemented efficiently.

  Supervision and inspection. In accordance with the requirements of supervision, accept the on-site and off-site supervision and inspection of the trading center, and timely submit accurate and complete information system information to the trading center; in case of violation, the trading center takes different restrictive means or penalties according to the regulations; at the same time, continuously improve its own professional and technical level to ensure system security.

  2. System operation safety, fast and standardized upgrade

  The essence of electronic trading of precious metals spot is to rely on the information system electronic platform for trading, all trading activities of customers are concentrated in the information system electronic platform, so only the construction and maintenance of a safe and fast operating system, according to the new problems arising from the expanding new business, and constantly amend the design of new programs and new ways, so as to reduce the risk while providing customers with a safer and more convenient experience and service.

  Security and speed. We pay attention to the security and integrity of customer funds, account numbers, passwords and other information, and make the transaction data such as customer warehouse receipts, flow, and statements instantly available, consistent and accurate, while ensuring that the system is constantly updated and upgraded with the external environment policies and new functional requirements of users, so that customers can operate more and more smoothly and conveniently.

  Update and upgrade. We also organize operation and maintenance meetings with the operation and maintenance staff of the trading center, technical support staff of the company and core members of each department on a regular basis to train on the operation of the new functions of the system, discuss problems and failures that occur during testing or use, put forward some suggestions for optimization, and organize and summarize them into written documents for submission to the relevant persons in charge so that they can be corrected and improved in the new version. The new version will be revised and improved.

  Strengthen monitoring. The risk control of trading has always been the top priority of the company. With the increasing problems of network security and virtual fraud, the trading system will face unprecedented challenges. Therefore there is a need to have more data information and provide more accurate data analysis to prevent and avoid mega trading risks within the system. For example.

  Adding a risk measurement function at the account opening stage to exclude some potential customers with low risk appetite or who have not engaged in risky investments will help the company reduce operational risks.

  In addition to using position warning, heavy position reminder, risk alert, and large account reporting mechanism in the trading stage, the balance monetization fund method or multi-account fund method can also be used for discounting to reduce the capital loss rate.

  The complaint stage can be set up industry investor blacklist, for frequent complaints, malicious operation and other customers to restrict their accounts in other industry platforms, purge the illegal behavior that disrupts the precious metals trading.

  The information system is constantly upgraded to the precious metals trading company in the operation and maintenance of the information system platform has put forward new requirements, at the same time, with the continuous innovation and development of precious metals trading, its electronic, information level will become higher and higher, the future stability of the information system, security, convenience will become the key link in the sustainable development of precious metals trading, so the company should continue to improve the standardized management of the information system platform, so that it is more secure and stable, more convenient. Therefore, the company will continue to improve the standardized management of the information system platform to make it safer, more stable, more convenient and efficient.

Introduction to the design and method of repairing cracks in architectural concrete structures

  With the initial completion of China’s modernization and construction tasks, the major cities have also been better developed, especially in recent years with the changes in diet, architecture, economy, lifestyle, etc., so that people’s needs for living gradually shift to the direction of quality.

However, in the actual real estate industry, conflicts between residents and construction companies often occur, and the key factor that causes these disputes lies in the quality of the building or in after-sales maintenance. In order to solve such problems, although China has introduced a number of policies, however, due to the continuous disputes in the real estate industry in recent years, coupled with the market downturn, such issues have also received the attention of all sectors of society, the following specific description of this aspect of the problem.


  Concrete structure is currently more widely used in the field of construction of building construction methods, from the application and development experience in recent years shows that the application of this structure, due to the influence of materials, technology, environment, management, technology and other factors, there are still problems such as water leakage, cracks, structural strength weakening, etc., and therefore should strengthen the exploration of these common problems, from which to find the causes of such problems, and accordingly To find specific solutions to improve the quality of buildings and provide safe and reliable living and office conditions for the public.

  Causes of concrete cracks

  1 From the aspect of material quality

  However, due to unqualified cement, sand, stone, etc., not meticulous market research in the material purchase, insufficient material experiments, greedy for cheap to buy “relationship materials, cheap materials”, etc., but did not choose the real standard materials suitable for the project requirements, or unreasonable ratio In addition, the quality of the building is caused by the combination of the materials, and then the formation of what is commonly known as “tofu dregs project”.

  2 From the deformation of the foundation

  Due to the existence of uneven settlement, the problem of cracking in the reinforced concrete structure will occur. Usually, the cracks are related to the foundation deformation in terms of size, shape and direction, and when the stress of the foundation deformation increases, it will result in penetrating cracks.

  3 Structure loading view

  Generally speaking, if the load on the structure exceeds the bearing capacity, it will cause cracks, and the formation of these cracks is also closely related to construction, use and other factors. In daily practice, it can be seen that the reinforced concrete beam and slab bending members in use will have cracks due to excessive load, and although the degree varies, it will bring more potential accidents due to the increase of time.

  4 From the design construction

  In the concrete structure, sudden changes in the cross-section of structural members, or unreasonable openings, grooves, etc., will cause the stress to gather, and therefore in the ring beam or hoop, hanging bars and other structural joints set unscientific, easy to cause concrete cracking.

  5 From the influence of humidity

  From the perspective of physics, the principle of thermal expansion and contraction is suitable for concrete materials, so when the concrete is hardened in the air, the volume will naturally shrink, which is related to the tensile stress generated in the component, especially in the early stage of concrete, the strength is low, so the shrinkage value will also reach the maximum; by inference, if the early maintenance work is not in place will naturally cause shrinkage cracks, from the form of expression, to Cast-in-place shear walls and pool bottom projects are more common.

  6 From the aspect of creep

  The main structural components, when its internal stress function, will be instantaneous so that the concrete structure in the elastic deformation, coupled with the extension of time, will produce the phenomenon of cracking, which is usually referred to as rheological deformation. If this happens, it will bring many stress losses to the prestressed members, and the crack resistance of the structure itself will be sharply reduced, and the more common area is in the tensile zone of the bending members.

  7 From the construction side

  Concrete structures are mainly used in building construction, but the cracking problem can be caused by the lack of safety and quality management, unreasonable construction process, strict supervision or unqualified material ratio, uneven vibrating during pouring, unscientific proportion of reinforcement, untimely maintenance, lack of protective measures in the construction environment, together with temperature and humidity, seasonal changes, and material transportation.

  Repair design

  In the principle of repair design of building concrete structure cracks, it is necessary to evaluate the judgment results of repair and reinforcement, and then implement restoration design for cracked structure function and durability. On the other hand, consideration of material, repair method and repair time should be paid attention to repair, and repair design work should be carried out based on these basic conditions. The details are as follows.

  First, the scope and scale of repair should be set and the site should be investigated and studied.

  Secondly, the cause, condition and degree of cracking, such as crack width, depth and type, should be recorded and analyzed, and the importance of the building, its general environment, factory area, salt environment, hot spring area, cold area and special use should be identified and distinguished.

  Thirdly, in the repair, there should be clear regulations and restoration goals set to ensure that the selected repair materials, methods and time meet the scientific and reasonable repair design; it is also necessary to compare the environmental conditions and give a higher grade repair design, preferably in the case of stable cracks to start the repair work, because various conditions will have different effects on the cracks, such as temperature, humidity, time, etc. changes in the repair affecting the cracks.

  Fourth, according to the practical experience of repair can be divided into stages in terms of repair recovery target; such as performance recovery, it is usually appropriate to restore it to the same performance of sound components, which is due to the cracks triggered by the cement aspect as the repair object, and generally can set its warranty life at 10 to 15 years; then the degree recovery, because the aggregate triggered by steel corrosion, alkaline aggregate will deteriorate, coupled with cracking causes, the analysis of all the causes is not yet clear, so usually the repair degree recovery time can be set at 5 to 10 years; there is also in the safety and reliability of the recovery situation, you can ensure the degree of personal safety as the basic standard, to start the emergency repair works.

  Fifth, it is necessary to pay attention to the matter that in the repair operation, adequate and specific research should be carried out, and the safety and security measures of mechanical materials, scaffolding, project site and surrounding people should be done.

  Repair methods and characteristics analysis

  There are many repair methods for cracks in building concrete structures, and the following is a specific description from the basically more common coating covering method, filling method, pre-stressing method and grouting method.   

 1 Coating method

  In the repair operation, in accordance with the requirements and relevant practical experience, usually for the concrete surface there are a large number of surface cracks line manual method or mechanical spraying method; principle is the repair material coated on the surface of the concrete, closed protection; in general, 0.3mm ~ 2.5mm thickness can meet the requirements of the coating film, note that the greater the thickness, the ability to adapt to changes in the crack will also be followed by increase; when using this method, the selected repair materials should be differentiated, such as in indoor, outdoor, different environments, different media, crack activities, etc., requiring careful analysis and strict selection.

The materials chosen in the usual repair construction should be targeted, such as the choice of epoxy asphalt-like rigid coatings in wear-resistant flooring, while for unstable cracks, polyurethane cool-like coatings with strong elastomeric properties should be the main focus.

  2 Filling method

  The filling method is mainly used to expand the cracks with steel brazier, wind pick and high-speed cutting discs to form a V-shaped or trapezoidal groove; then, epoxy mortar, cement mortar, PVC mastic and asphalt grease are used to form a closed protection by layering pressure smear.

This method is very suitable for repairing general cracks and water seepage cracks, for example, V-shaped can be applied to general cracks, while trapezoidal can be applied to water seepage cracks; in terms of material analysis, epoxy mortar can be chosen when high structural strength is required, while polyvinyl chloride and asphalt plaster are suitable for repairing leakage only.

  3 Prestressing method

  The application of prestressing method is mainly through it to achieve nut tightening to reduce cracks or make them close; for example, after drilling holes for members with drilling machine and penetrating bolts, it can increase the prestressing force to prompt nut tightening and achieve the purpose of crack repair; if the relevant conditions and standards are met, the two-way prestressing method can be applied with better effect, for example, when the direction of hole formation and the direction of cracks form vertical or not prevails.

  4 Grouting method

  The so-called grouting method is to pour cement or other chemical slurry into the concrete joints to play the purpose of curing when spreading, thus forming a buried strength to increase the integrity of the member, promoting the recovery of the use function, allowing its durable strength to increase, and achieving the goal of plugging and preventing rust. From the material aspect, epoxy resin slurry and methacrylate-based can be widely applied to structural repair; water glass, acrylic phthalan, polyurethane cool, acrylic salt-based, can be widely applied to prevent and stop leaks; from the functional point of view, the filling of such insoluble materials can effectively increase the strength of the building, so that its water barrier performance is strengthened.


  In conclusion, from the perspective of development, in the new era, we should insist on keeping pace with the times, adapting to the times and the local conditions. Because from the current market situation of the real estate industry, there is an oversupply and an obvious problem of excess stock, but on the other hand, it should be recognized that the people’s demand for housing quality and the concern of after-sales service quality.

Therefore, construction enterprises should summarize and analyze all aspects of the problems through property, treat all aspects of things seriously, and solve the real problems of residents in a timely manner, so as to further promote the harmonious relationship between enterprises and the public, and make a citizen’s obligation for a socialist harmonious society.

At the same time, it is also necessary to have a systematic study and setting of solutions to such problems, so as to make some useful achievements in this aspect, thus enhancing people’s interest in the real estate industry and further boosting the demand for buying houses.

Exploring the construction technology of concrete structure conversion layer of high-rise building

With the continuous progress of social economy and the rapid development of science and technology, China’s construction engineering industry has been greatly developed. The construction of the conversion layer occupies an important position in the construction of high-rise building projects. In the construction of the project, the construction enterprises must strictly follow the construction specifications for construction and operation, improve the level of construction technology, fully understand and master the characteristics and forms of the conversion layer, which can not only ensure the overall quality of the project construction and extend the service life of the project, but also promote the healthy development of the enterprise.

Structural arrangement of high-rise conversion layer

In the building structure with conversion layer at the bottom, some vertical members of the upper part of the conversion layer cannot be directly connected to the ground, therefore, safe and reliable conversion members must be set. According to the existing engineering experience and research results, the conversion members can be used in the form of conversion beams, analysis frame, hollow analysis frame, diagonal bracing, box structure and thick plate.

Due to the conversion of thick plate in the seismic zone less experience, can be used in the non-seismic zone and 6 degrees seismic design, for large space basement, because of the surrounding restraint, seismic response is less than the above-ground frame support structure, so 7 degrees, 8 degrees seismic design of the basement can be used thick plate conversion layer.

The arrangement of floor shear walls and frame struts plays a very important role in preventing the collapse of the substructure in the earthquake. The design of the conversion layer occupies an important position in the construction of building projects. In the construction of building projects, only by improving the design level of the conversion layer and accurately mastering the design points can ensure the quality of construction.

Construction companies must pay great attention to technology and practical experience, etc., in the construction process to increase the scientific nature of the design of the building conversion layer, in order to improve the quality and safety of the building.

1, reduce the conversion.

When laying out the vertical structure of the main body above and below the conversion layer, pay attention to make as much as possible the upper vertical structure can be down to the ground continuous through, especially the core of the core of the frame core structure should be up and down through.

2.Direct force transmission.

When laying out the upper and lower main vertical structure of the conversion layer, pay attention to make the horizontal conversion structure transfer force directly as far as possible, avoid multi-level complex conversion as far as possible, carefully use the complex force transfer, seismic adverse flat thick plate conversion, such as the upper and lower column network really can not be aligned, try to use box conversion.

3, strengthen the lower, weaken the upper.

For the conversion layer of the shear wall structure or cylinder structure, the following measures can be taken: strengthen the lower structure to increase the thickness of the cylinder and floor wall, improve the concrete strength level, if necessary, can be placed around the house part of the additional shear wall, wall frame or stairwell cylinder, improve seismic capacity; can take the following measures to weaken the upper: no floor shear wall openings, openings, reduce wall thickness, etc..

4、Optimize the conversion structure.

Seismic design, when the building function must not be converted to a high level when the conversion structure should be preferred not to cause the seismic action of the frame pillar (side column) column top bending moment too large, column shear too large structural forms, such as diagonal web truss, hollow web truss and flat beam, etc., while paying attention to the need to meet the strength and stiffness requirements under the action of gravity loads.

5.Comprehensive and detailed calculation.

The transformation structure must be taken as an important part of the overall structure, and a calculation model conforming to the actual state of stress and deformation must be used to calculate and analyze the overall structure in three dimensions. If necessary, the finite element method can be used for local supplementary calculation of the conversion structure, at least two layers of the structure above the conversion structure into the local calculation model, and pay attention to the model boundary conditions in line with the actual working state.

6.Technical points of building conversion layer

In recent years, with the continuous and rapid development of China’s economy, people’s functional requirements for high-rise buildings tend to be diversified, integrated and comprehensive. In order to meet the requirements of the building it is necessary to set the conversion layer at the floor where the upper and lower different structural systems are converted.

1、Frame pillar

The cross-sectional size of frame column is mainly controlled by the axial compression ratio and should meet the requirements of shear compression ratio. In order to ensure that the frame column has sufficient ductility, the axial compression ratio should be strictly controlled. Project frame pillar seismic grade for the special level, axial pressure ratio shall not be greater than 0.6, part of the formation of large cross-sectional size and “short column”, shall not be greater than 0.55. Column section ductility also has a close relationship with the hoop rate, so the frame pillar hoop rate is also much larger than the general frame column.

Hoop reinforcement shall not be less than Ф10 @ 100, full-length encryption, and the hoop rate shall not be less than 1.5%. In the project, individual frame pillars also do shear wall end columns, so should also meet the constraints of the edge members with hoop characteristic value of not less than 0.2 requirements, converted into the hoop rate (C50 concrete) that is 2.64%. The frame pillar is a very important member, in order to increase the safety, the column end shear force and column end bending moment should be multiplied by the corresponding increase factor, each floor frame pillar to bear the sum of shear force should be taken as 30% of the base shear force. Because the program calculation, generally assume that the floor stiffness is infinite, horizontal shear force according to the stiffness of the vertical components distribution. The bottom shear wall stiffness is much larger than the frame pillar, making the frame pillar shear force very small.

However, considering the deformation of the floor slab and the decrease in stiffness of the shear wall after cracks appear in the actual project, the frame column shear force will increase. Therefore, the increased shear force of the frame column is separately specified. In addition, in order to strengthen the upper and lower connection of the conversion layer, the longitudinal reinforcement within the upper wall of the frame strut should be extended into the upper wall within the first layer; the rest of the longitudinal reinforcement outside the wall range is anchored horizontally into the conversion layer beam slab to meet the anchorage requirements LaE.

2、Box-supported beam

The cross-sectional size of the frame supported beam is generally controlled by the shear compression ratio, the width is not less than 2 times the thickness of the upper wall and not less than 400mm; the height is not less than 1/6 of the calculated span; the width of the frame supported beam is uniformly set at 800mm; the frame supported beam is subjected to huge and complex forces, it is not only the transmission hub of the upper and lower loads, but also the key part to ensure the seismic performance of the frame supported shear wall, which is a complex and important force-bearing member. The longitudinal reinforcement rate of the frame supported beam shall not be less than 0.6% for the special seismic grade.

The reinforcement rate of frame-supported beams shall not be less than 0.8% if the calculation requirements are met. Box-supported beams are generally eccentric tension members with axial forces in the beam, and therefore should be equipped with sufficient number of lumbar bars. Girders Ф16, along the beam height spacing of not more than 200mm, and should be reliable anchor into the support. Frame beam shear is very large, and for such an important part of the seismic, more emphasis should be placed on the “strong shear weak bending” principle, in the case of longitudinal reinforcement has a certain surplus, the hoop reinforcement should be strengthened. Hoop uniform use of Ф14 @ 100 eight limb hoop full-length encryption, with a hoop rate of 1?.53%, much greater than the literature on the special grade seismic conditions of the frame support beam with hoop rate requirements.

3、Conversion floor slab

The frame supported shear wall structure is divided by the conversion floor, and the internal force distribution law is different between the upper and lower parts. In the upper floor, the horizontal force generated by the external load is largely distributed in proportion to the equivalent stiffness of each shear wall; while in the lower floor, due to the difference in stiffness between the frame strut and the floor shear wall, the horizontal shear force is mainly concentrated on the floor shear wall, i.e., the load distribution at the conversion level produces sudden changes. The conversion floor slab assumes the task of completing the redistribution of the shear force between the upper and lower parts.

And because the conversion floor slab itself in-plane force is very large, and the deformation is also very large, so the conversion floor slab must have sufficient stiffness for guarantee. Conversion floor slab using C50 concrete, thickness 180mm. Ф14@ 150 steel double two-way whole plate pull through, reinforcement rate of 0.28%. In addition, in order to assist the conversion floor slab to complete the redistribution of shear forces, the layer above the two layers and the following layers of the floor slab is also appropriate to strengthen, are taken thickness of 150mm.


To sum up, with the rapid growth of national economy, the construction industry as an important support of national economy, the development of its industry plays a decisive role in the growth of national economy.

As an important part of the construction industry, high-rise building occupies an important position in the development of the construction industry. As an essential construction link in the construction of high-rise buildings, the construction of conversion layer

In order to ensure the overall quality of the building, construction enterprises must improve the technical level of the construction of the conversion layer and do a good job of maintenance, only in this way can provide a strong guarantee for the development of the enterprise.

Die wichtigsten Punkte des Betonbaus in Wasserschutz- und Wasserkraftwerken

1.die derzeitige Situation des Betonmanagements in Chinas Wasserschutz- und Wasserkraftbauprojekten

1.1 Die Lücke im Managementkonzept

Der Bau von Wasserschutz- und Wasserkraftprojekten ist ein wichtiger Teil der Verwirklichung der sozialistischen Modernisierung, obwohl wir im technischen Bereich der Wasserschutz- und Wasserkrafttechnik weltweit eine führende Position einnehmen, gibt es jedoch kein vollständiges System für die Verwaltung von Beton, und das Baupersonal neigt dazu, je nach Größe der Wasserschutz- und Wasserkraftprojekte unterschiedliche Einstellungen zur Betonverwaltung zu haben, das Bauvolumen von Großprojekten, die Betonverwaltung wird Der Bau von großvolumigen Projekten, die konkrete Verwaltung wird die Aufmerksamkeit auf, kleine Projekte, in Bezug auf die konkrete Verwaltung wird leicht zu ignorieren, wie ein Management-Konzept ist sicherlich falsch. Sie kann nicht aufgrund des geringen Projektvolumens ignoriert werden, da Wasserschutz- und Wasserkraftprojekte eine lange Lebensdauer haben und ein Projekt in der Regel mehreren Generationen dienen wird.

1.2 Mangelndes Managementwissen

Mangelndes Managementwissen ist auch ein wichtiger Faktor, der das Management von Beton in Wasserschutz- und Wasserkraftprojekten beeinträchtigt. Obwohl unsere Bautechnologie nicht von der europäischen und amerikanischen abweicht und wir in einigen Aspekten Europa und Amerika sogar voraus sind, gibt es doch eine Wissenslücke in Bezug auf das Betonmanagement. Das Baupersonal in Europa und Amerika ist besser ausgebildet und verfügt über ein hohes Maß an Wissen über das Betonmanagement, während das Baupersonal in China, vor allem auf der untersten Ebene, im Allgemeinen nicht sehr gut ausgebildet ist und daher kein Betonmanagement besitzt.

1.3 Mangel an Maschinen

Die Verwaltung von Beton ist nicht nur die Verantwortung der Bau-Personal, das Management von Maschinen ist auch einer der wichtigsten Gründe, die Verdünnung von Beton kann mit bloßem Auge beobachtet werden, der Grad der Säure und Alkalinität von Beton muss mit Hilfe von Messgeräten durchgeführt werden, der Grad der Säure und Alkalinität von Beton bestimmt den Grad der Korrosionsbeständigkeit und hat einen gewissen Einfluss auf die Umgebung, vor allem das Wasser am Boden des Staudamms und der pH-Wert des Betons zu groß ist, wird es die Korrosion von Beton beschleunigen . Der Einsatz von Maschinen ist bei der Verwaltung von Beton sehr wichtig.

2.die wichtigsten Punkte des Betonbauprozesses in Wasserschutz- und Wasserkraftwerken

2.1 Verstärkung der Kontrolle von Betonschalungen

Im Betonbau hat die Betonschalung einen wichtigen Einfluss auf die Qualität des Betons. Um die Kontrolle der Schalung zu verstärken und die Vorteile der Schalungskontrolle zu gewährleisten, sollten die Graswurzelbehandlung und die Fertigstellung der Ausgleichsschicht durchgeführt werden, und die Schalung sollte auf der Grundlage der Reinigung des schwimmenden Bodens und der Behandlung des Schutts errichtet werden. Anschließend werden die Höhe der Schalung und die Abstände zwischen den Platten sorgfältig geprüft und festgelegt. Um die Schalung nach Abschluss der Betonarbeiten zu demontieren, kann vor dem Gießen des Betons eine Sperre auf die Schalung aufgebracht oder eine Kunststofffolie verlegt werden. Auf diese Weise kann die Folie zur Abdichtung verwendet werden, verhindert das Austreten von Gülle, sorgt dafür, dass die Oberfläche des Betons schöner und ebener wird, verhindert das Entstehen von Waben, sorgt für die Dichtheit der Plattenkante und der Plattenecke und gewährleistet die Qualität des Betons.

2.2 Strenge Kontrolle der Betonmischung vor dem Eintritt

Verschiedene Materialien für Beton haben einen wichtigen Einfluss auf die Konstruktion und die Qualität von Beton. Die Betonmaterialien sollten vor dem Betreten der Baustelle geprüft werden, und Baumaterialien, die die Prüfung nicht bestehen, dürfen nicht auf die Betonbaustelle gebracht werden. In der Betonmischung, um streng mit dem Bau Anforderungen des Wasserschutzes und Wasserkraft-Projekte, wiegen das fertige Wasser Reduktionsmittel und dann in Plastiktüten für die Erhaltung setzen. Die Betonbaustoffe als Grundlage für die Gewährleistung der Qualität des Betonbaus sollten streng kontrolliert werden.

Bei der Dosierung von Betonbaustoffen werden die verschiedenen Materialien nicht genau gewogen, oder das Verhältnis der Baustoffe wird nicht entsprechend den tatsächlichen Änderungen des Wassergehalts von Sand und Gesteinskörnungen geändert, was zu Änderungen des Wasser-Zement-Verhältnisses und des Schlamm-Kies-Verhältnisses führt, was sich auf die Fließfähigkeit, Festigkeit, Kompaktheit und Kohäsion des Betons auswirkt und die Qualität des Betons beeinträchtigt. Bei der Zugabe der Materialien für den Betonbau in den Trichter ist es auch notwendig, eine bestimmte Reihenfolge einzuhalten, im Falle der Nichtzugabe von Mischungen und Zusatzmitteln ist es im Allgemeinen notwendig, zuerst Steine, dann Zement und schließlich Sand in den Trichter zu geben; im Falle der Zugabe von Mischungen im Bau ist es notwendig, zuerst Steine, dann Zement, Mischungen und Sand in dieser Reihenfolge zu geben; im Falle der Zugabe von Trockenmischungen im Bau ist es notwendig, zuerst Steine, dann Zusatzmittel, Zement und Sand. Achten Sie beim Mischen des Betons darauf, dass die vorgeschriebene Mindestmischzeit nicht unterschritten wird.

Wenn die Anforderungen an den Beton den Vorschriften entsprechen, wird man beim Mischen feststellen, dass die Mischung gleichmäßig gemischt ist, die Farbe der Mischung ebenfalls einheitlich ist und die Mischung auch Wasserrückhaltevermögen, Kohäsion und Fließfähigkeit aufweist; wenn der Bau von Beton für Wasserschutz- und Wasserkraftwerke nicht den einschlägigen Anforderungen entspricht, sollte eine umfassende Analyse durchgeführt werden, um die Gründe herauszufinden und rechtzeitig Anpassungen vorzunehmen.

Gleichzeitig sollte spezialisiertes Personal eingesetzt werden, um Klumpen, übergroße Partikel und andere Verunreinigungen zu beseitigen, um die Qualität der Mischung zu gewährleisten; der Beton sollte unter Berücksichtigung von Vibration und Verdichtung eingebracht werden, um Probleme mit Über- oder Untervibration zu vermeiden, wobei besonders auf den Schalungslauf und Leckagen in der Innenform zu achten ist. Wenn die Festigkeit des Betons gewährleistet ist, wird von Hand gemeißelt.

Darüber hinaus gibt es Vorschriften für die Abweichung bei der Verwiegung von Rohstoffen für Beton, in der Regel etwa 2 % für Zementzusatzmittel, 2 % für Wasserzusatzmittel und 3 % für grobe und feine Zuschlagstoffe. Es ist zu beachten, dass beim Mischen des Betons der Wassergehalt schwankt, und bei Regen sollte die Anzahl der Kontrollen des Wassergehalts erhöht werden, damit die Menge der Zuschlagstoffe und des Wassers entsprechend angepasst werden kann, und zwar mindestens einmal in jeder Arbeitsschicht. Zu beachten ist auch, dass die Zeit zwischen dem Einbringen des Betons und dem Transport sowie die Zeitspanne zwischen dem Einbringen des Betons und dem Transport geringer sein sollte als die Erstarrungszeit des Betons.

2.3 Einbau des Betons

Die an der Einbaustelle angelieferten Mischungen werden direkt in die Schalungströge eingebracht und von Hand eingebaut, um eine homogene Oberfläche zu gewährleisten; die Mischungen mit offensichtlicher Entmischung werden neu gemischt. Das Verteilen des Betons erfolgt so, dass der lose Beton 10 % über der geplanten Oberkante der Schalung liegt. Construction Lücke kann nicht mehr als 1 Stunde, innerhalb von 1 Stunde der Unterbrechung, können Sie Säcke verwenden, um den Beton, der geschlagen wurde, nach der Wiederaufnahme der Arbeit harken losen Beton, weiter zu ebnen.

3.die Betoninstandhaltung im Wasser- und Wasserkraftwerksbau

Die Instandhaltung von Beton spielt eine sehr wichtige Rolle bei der Sicherstellung der Qualität von Beton. Die Instandhaltung von Beton ist langwierig. Bei der Instandhaltung von Beton sollten die Materialeigenschaften des Betons, die klimatischen Bedingungen und andere Faktoren berücksichtigt werden, um geeignete Instandhaltungsmaßnahmen zu ergreifen.

Im Allgemeinen wird Beton durch natürliche Methoden wie das Aufsprühen von Folien und das Einwickeln von Kunststofffolien ausgehärtet. Bei wärmeren und trockeneren Bedingungen ist es wichtig, den Beton nach dem Entschalen mit Wasser zu besprühen und ihn gleichzeitig mit oder ohne Rasengitter abzudecken, was zwischen drei und vier Wochen dauert. Der Beton wird von einer Person gewartet, die dafür sorgt, dass die Betonkonstruktion feucht ist und entsprechend dem feuchten Zustand des Betonmaterials und der Bauumgebung angepasst wird.

Während der Herstellung des Betons ist der Festigkeitsfaktor des mit Wasser bedeckten Betons höher als der des nicht bedeckten Betons, und die Festigkeit des Betons während der Instandhaltung ist höher als die geplante Festigkeit des Betons unter dem Einfluss verschiedener betonbezogener Faktoren. Bei weniger windigen Bedingungen kann der Beton mit einer wasserdampfundurchlässigen Kunststofffolie ausgehärtet werden, um die Feuchtigkeit im Beton zu halten und seine Festigkeit zu verbessern.

Es gibt jedoch viele Probleme mit dieser Methode der Nachbehandlung, und die durchschnittliche Leichtigkeit des Betons ist nicht vollständig garantiert und muss mit Vorsicht angewendet werden. Darüber hinaus wurde die Entstehung von Nachbehandlungsmitteln in der Betoninstandhaltung auf den Prozess der Betoninstandhaltung übertragen.


Die Qualität des Betonbaus wirkt sich unmittelbar auf den Wasserschutz und den Bau von Wasserkraftwerken aus. Der Betonbau umfasst viele Konstruktionspunkte und die Konstruktionstechniken sind komplex.
