Drainage construction problems in urban construction?

1 Problems in Drainage Engineering in Urban Construction

1. 1 Problems in drainage construction technology

Problems of 1. 1. 1 in the construction route. In urban building drainage engineering, the construction route is a very important link in the whole construction process. Although there are mature schemes for route selection, there are still some problems in the construction. The main reason for this problem is that the construction unit is trying to save costs. The project cost is the key issue that the construction unit needs to consider, because it is directly related to the interests of the construction unit. In order to save costs, some construction units can not meet the actual situation of urban infrastructure construction, leading to quality problems and laying a safety hazard for urban drainage projects. The unscientific selection of construction route is also an important problem. The construction line requires the construction unit to have standard construction specifications and combine modern science and technology to ensure the professionalism and technicality of line selection.

Problems in the design of 1. 1.2. For any project, the problem of construction design is the key factor affecting the construction quality, and so is the urban drainage project. As an urban project, urban drainage project is a typical representative of the completion of construction relying on underground space. On the surface, there is indeed more available space on the ground, but there are also many types of underground city construction, so the underground space becomes very crowded. In this case, if the design problems in the construction are not found, it will not only affect the construction quality of urban drainage projects, but also affect urban drainage projects and bring many problems to other urban projects. In addition, if the construction design problems are found in the construction process, the construction of urban drainage projects will be put on hold, and solving this problem at this time will cause great inconvenience to residents' daily traffic and affect the quality of urban life.

1. 1.3 Impact of buildings. In the process of drainage engineering construction, it may be encountered that the existing buildings cannot be designed and built as expected due to the influence of the existing buildings. In this case, there are two solutions: demolishing the building or modifying the design idea, and building a bypass pipeline to bypass the building. Because the cost of construction and demolition will be high, and there is a relatively large amount of demolition work, the pipeline design scheme that bypasses the building is generally chosen. Choosing this scheme will require the pipeline to keep a safe distance from the building so as not to affect the construction. Other factors, such as traffic, need to be considered in the construction process.

1.2 problems in drainage construction management

The management of drainage engineering is an important issue, which exists in all aspects of construction. In the preparation stage of construction, construction quality is an important supervision goal, so as to strictly control quality and prevent the possibility of quality accidents. In addition, in the construction of urban drainage projects, the project office should strictly check the work of construction units and supervision units. Follow-up project related personnel, quality inspectors and project engineers shall supervise and manage the construction project at the same time, and modify the problems in the construction in time. Specific management issues are as follows.

1.2. 1 pre-construction management issues. The management before construction is mainly to review the construction drawings and survey the construction site. If the work before construction can't be thorough and meticulous, there will be many unpredictable problems in the construction process, which will lead to the reduction of the progress and quality of the whole construction. In order to effectively control the construction progress and quality, a comprehensive plan should be made for construction quality control before construction to ensure the procedures, quality control and quality inspection methods in the construction process.

1.2.2 management problems in the construction process. Because of the great complexity of urban drainage engineering, the management in the construction process is very important. In the process of construction, the quality inspection of materials is often not strict enough. In this respect, it is difficult for all units to achieve the unification of standards, which leads to the inability to make unified arrangements for the work during the construction process, laying a safety hazard for the construction work.

1.2.3 post-construction management. At present, China's drainage engineering construction acceptance management system is not perfect, drainage professional and technical personnel are relatively few, and there are many problems in post-construction acceptance. However, problems such as careless inspection or incomplete acceptance will lay hidden dangers for construction quality and safety.

2 Measures to improve urban drainage construction

As the most typical engineering construction project, to effectively solve the problem of urban drainage construction, we must effectively deal with various influencing factors. Based on the above analysis of the problems affecting the construction quality of urban drainage projects, the measures to improve the construction effect of drainage projects are discussed as follows.

2. 1 Design of network management scheme

It is particularly important to improve the construction effect of drainage project and ensure the scientific nature of the project. When designing urban drainage projects, designers must fully study and investigate the city to solve the actual needs of drainage service network of drainage projects. First of all, we should follow the reasonable design process to meet the basic residents' service of the drainage project. Secondly, check the geological conditions to ensure the reasonable design of earthwork. Thirdly, according to the actual situation of underground facilities, all kinds of urban facilities are effectively avoided, and the overlap of pipeline projects in different urban construction is avoided.

2.2 Selection of construction technology

In the process of improving the construction effect of drainage engineering, the selection of construction technology is also very important. In the process of construction, construction enterprises should follow their guiding principles and choose reasonable and effective construction techniques and methods on the basis of construction design. Under the requirement of correct operation of construction technology, the construction behavior of urban drainage engineering is effectively guided and corrected, which further ensures the correctness of the selected construction technology and the rationality of its application, so that the construction quality of urban drainage engineering is fundamentally guaranteed and supported.

2.3 Ensure the quality of building materials

Pipeline is the most used building material in urban drainage engineering construction, and the quality of pipeline in urban drainage engineering construction directly affects the engineering quality. Therefore, in order to ensure the quality of pipes, construction enterprises must start from the following aspects in the construction process: (1) Ensure the basic quality of pipes. In this link, the construction enterprise should ensure the qualification and trading reputation of the pipe manufacturer and the reputation of the manufacturer. At the same time, we should also check the quality of pipes through regular inspection and sampling inspection to avoid the appearance of inferior pipes. (2) Ensure that the selected pipes meet the needs of urban drainage engineering. Through the repeated confirmation of construction design, select the pipes with good quality, and purchase the pipes according to the required types and quantities to avoid mistakes. (3) Reasonable storage. In the storage of pipes, ensure the classified storage of pipes and cover them all with tarpaulins to avoid the influence of exposure and rain on the quality of pipes.

2.4 Improve the technical skills of personnel and cultivate their working ability.

The completion of high-quality construction projects is inseparable from a high-tech construction team. In this part of the construction, the construction team of the construction company needs to do: (1) do a good job in building a team of professional and technical personnel. When recruiting construction workers or teams, it is necessary to check the basic construction technology to ensure that its construction technology can meet the needs of urban drainage construction. At the same time, we should identify their qualifications, so that one person can have one certificate and hold relevant certificates. (2) Do a good job in technical training of the construction team. With the emergence of new technologies, construction enterprises conduct technical training for their own construction teams to ensure that every internal construction worker can master the new construction technology. In addition, their basic construction technology is regularly assessed, and technical training must be carried out if they fail to pass the assessment, and they can only be re-employed after passing the assessment.

3 Conclusion

At present, there are still many problems in the design and planning of water supply and drainage projects in domestic urban construction, which makes the planning and design of urban water supply and drainage not ideal. With the development and progress of society, the quality requirements and standards of urban water supply and drainage planning and design will be higher and higher with the development of the city, and the responsibility requirements and technical requirements for designers will be higher and higher. In the process of construction, the construction unit should carry out the construction according to the actual situation and design drawings to prevent problems in the construction process and avoid problems in the drainage construction process. Ensure the normal operation of urban drainage and promote the better and faster development of the city.
