Discussion on management measures of sluice construction in water conservancy construction stage?

In the stage of water conservancy construction, it is very important to explore the management measures of sluice construction. Only through reasonable measures can the expected effect be achieved, and every detail is crucial. Zhong Da consulted, explored and introduced the management measures of sluice construction in the stage of water conservancy construction.

The management quality of sluice project in water conservancy construction directly affects the quality of sluice project. In order to ensure the quality of the project, we must first make clear the node function of the sluice project, rationally plan the construction, control the working quality and material quality of concrete and metal structures, and avoid various common quality hidden dangers in the construction. Only by unremitting efforts can the management work be put in place and the quality of sluice project be effectively guaranteed.

1. Application significance of sluice construction management

Sluice, as one of the hydraulic structures, is mainly used to control water quantity, reasonably discharge water and store water by opening and closing the sluice. Because sluice has many functions and great functions, sluice construction management plays a great role in the quality of water conservancy construction projects. Sluice construction management runs through the whole construction process, from pre-construction management, construction process management to post-construction management. According to the requirements of engineering design, the construction is effectively combined with the actual situation of the construction site to improve the effectiveness of construction management. Sluice construction management directly affects the quality of water conservancy projects. High engineering quality can ensure the normal operation of water conservancy projects, ensure the normal operation of water conservancy projects and improve the development speed of water conservancy projects in China. In addition, efficient sluice construction management can ensure the safety of life and property of construction workers and promote the harmonious development of society.

2. Several problems in sluice construction management

The shortage of sluice construction management has seriously affected the construction management level and the quality of water conservancy projects, and its shortcomings mainly include several aspects.

(1) insufficient preparation. The drawing design in the early stage of construction is very important, which needs to be designed in full combination with the actual environment of the construction site and revised and improved repeatedly. Because the engineering quality and social value are fully considered in the drawing design, it is easy to lead to unscientific and insufficient preparatory work.

(2) The division of responsibilities is not clear. Due to the particularity of sluice construction project, it is both complicated and dangerous. The whole sluice project needs open-air construction, which has high risk factor and is greatly influenced by environmental factors. There are many types and quantities of construction equipment and many raw materials needed in the construction process. Because of the unclear division of responsibilities in sluice construction, it is easy to cause the problem that no one is responsible for the accident, which leads to the problem not being dealt with in time.

(3) Weak quality awareness. Because the overall quality of sluice construction personnel is low, the awareness of quality and safety is relatively low; Construction technicians are not clear enough about the water conservancy engineering system. Although managers have certain management ability, they lack professional knowledge of hydraulic engineering, which will seriously affect the construction process and project quality.

(4) Lack of perfect management system. The whole water conservancy project needs a perfect management system to ensure the high-quality completion of the project. However, in the actual construction and operation, the sluice management system is not perfect, and there is still a lack of systematic management in technology, construction and material reserve.

3. 1 management before construction

(1) Carefully review the various systems and systems of the sluice construction unit, and define the engineering technical scheme and measures.

(2) Do a good job in the handover management of design drawings, make clear the technical quality standards and matters needing attention in the construction process, carefully complete the joint review of construction drawings, and explore effective preventive measures for problems arising in construction management to ensure the smooth progress of sluice construction.

(3) In the early stage of formal construction, a safe and effective production management system should be formulated, and a special gate construction management team should be organized to supervise, manage and coordinate the whole construction process in detail. Combined with the sluice construction process, the sluice construction management team is often divided into five groups: construction group, inspection group, electromechanical group, material group and technical group. Among them, the main task of the construction team is to record the excavation, pouring and construction data of the sluice project, and the project record is mainly to provide proof materials for the later project acceptance; The inspection team is mainly responsible for the pay-off, measurement and construction inspection of the sluice installation line to ensure that the actual construction size meets the engineering design requirements; The electromechanical group is responsible for the lifting and pressure test of the door body; The material group is mainly responsible for providing materials related to gate construction, ensuring the quality of construction materials and preventing the decline of engineering quality due to unqualified construction materials; The main responsibility of the technical team is to supervise and accept the sluice project, such as concrete mixing ratio, block pressure test and other technologies, as well as the collection and archiving of construction data.

3.2 Construction process management

3.2. 1 Foundation construction management

Due to the particularity of water conservancy project, the foundation construction requirements of important parts are quite high, and the quality of foundation construction is seriously related to the engineering quality of the whole water conservancy project. Therefore, in the process of engineering construction, we should do a good job in the construction management of foundation engineering. The quality and strength of sluice directly affect the quality of sluice. Because of the great pressure of water on sluice, it is necessary to improve the quality and strength of sluice to ensure the quality of sluice. The excavation amount of foundation excavation will seriously affect the strength of sluice, and less excavation will reduce the strength of sluice, thus reducing the construction quality of sluice. If the excavation amount is large, it will lead to the increase of backfill construction and further increase the cost of manpower, material resources and financial resources. Therefore, the excavation amount should be strictly calculated and controlled in actual construction to prevent the excavation amount from affecting the strength and quality of the sluice.

3.2.2 Concrete Construction Management

As a key component of sluice project, concrete construction quality seriously affects the quality of sluice project, so concrete construction management is very important. In practical engineering, the specific management starts from three aspects.

(1) concrete building materials. When purchasing raw materials such as steel bars and cement, the construction party needs to conduct a comprehensive investigation of raw materials and choose building materials with high cost performance. At the same time, before the materials are put into use, the quality of the materials must be comprehensively inspected. The main inspection items of steel include cold bending, tensile strength, yield strength and other mechanical properties, and carefully check whether these items meet the actual engineering requirements; The main inspection item of cement is cement label to see whether it meets the engineering requirements and relevant national specifications. In addition, special attention should be paid to the storage of building materials to avoid the deterioration of cement and the decline of mechanical properties of steel due to moisture and rust during storage. Therefore, building materials should be carefully inspected and stored.

(2) Concrete mix proportion. The control of concrete mix proportion is an important part of concrete construction management, and the concrete mix proportion of different projects is different. In the actual concrete construction, there are many factors that affect the mix proportion, such as weather factors, construction equipment, transportation conditions, etc., so it is necessary to fully combine the actual situation of the project and rationally optimize the concrete mix proportion. In order to prepare concrete that meets the construction requirements, the moisture content of concrete must be reasonably controlled to meet the actual engineering requirements. In actual engineering construction, in order to ensure the performance of concrete to meet the engineering requirements, in addition to reasonably controlling the configuration ratio, additives with different properties should be added appropriately, and the amount of additives should meet the requirements of related projects, so as to achieve the effect of improving the performance of concrete.

(3) Concrete pouring and vibrating. In the process of concrete construction, pouring and vibrating construction is very important, and it is also an important part of sluice construction management. When pouring concrete, special attention should be paid to the continuity of pouring to ensure continuous pouring as much as possible. After the completion of concrete pouring construction, vibrating construction should be carried out in time. Poor vibrating construction can easily lead to problems such as cracks, pits, holes, honeycombs and air holes in concrete, which seriously affect the quality of concrete. These quality defects will cause safety hazards to the sluice and even the whole water conservancy project. Therefore, in actual construction, construction personnel must attach importance to concrete vibrating construction, and carry out concrete pouring and vibrating construction in strict accordance with relevant construction technical requirements and specifications, and quality inspectors should also strengthen the construction quality inspection of concrete pouring and vibrating.

3.3 Post-construction management

(1) After the sluice construction is completed, the local government departments and relevant quality inspection departments should strictly check the quality of the sluice project. Once the unqualified parts are found, the contractor shall be informed in time and required to make rectification and adjustment. If the situation is serious, it needs to be rebuilt to ensure that the construction quality of the sluice meets the actual needs of the project, so that the sluice project and the whole water conservancy project have high practicability and safety.

(2) During the later operation of sluices and water conservancy projects, it is necessary to formulate perfect later maintenance systems and measures, regularly and irregularly carry out comprehensive maintenance and maintenance of the projects, and ensure that sluices and water conservancy projects always maintain good operating conditions and operate safely, normally and effectively.

4. Conclusion

To sum up, as an important part of water conservancy project, the construction quality of sluice will have a great impact on the overall quality of water conservancy project. Therefore, in the construction of sluice project, corresponding management measures should be taken according to the existing problems to ensure the construction quality of sluice project and give full play to the role of sluice project.
