How do the municipal water supply and drainage construction quality management and control

[Abstract] In the modern city's overall planning and construction, water supply and drainage as the basis for public works projects, one for its construction management and strict quality control is of great significance. At present, the domestic municipal water supply and drainage construction affect the construction quality management and control of many factors, must lead to municipal engineering and construction management unit of attention.

[Keywords:] Municipal; to the drainage works, construction quality, management, control

In China's urban construction, the municipal water supply and drainage works is to protect the city's economic construction and people's everyday life is based, to the drainage system of scientific planning and construction of urban infrastructure is an important indicator of maturing in the municipal water supply and drainage construction, quality management and control is to achieve the desired goals will be directly related to the overall function of the city to play, but also for the city's environmental protection, transportation and flood control have an important role, therefore, timely to enhance construction quality for municipal water supply and drainage management and control of research is necessary, but also for urban development has far-reaching significance.

A municipal water supply and drainage construction quality management and control problems
With the accelerated urbanization process, urban expansion and the increase in the number, speed up the construction of urban water supply and drainage system will not only meet the basic water supply and urban drainage needs, but also for the city's water pollution control, and water resources of the circulatory system building has a positive role in promoting, but due to the Project Management concepts, models, systems, methods, and construction Technology, the impact of Technology and other factors and limitations of municipal water supply and drainage construction prevalent in some quality problems, management and control lack of or inadequate measures are one of the factors can not be ignored. Municipal water supply and drainage construction quality management and control problems, mainly in the following areas:
1.1 Construction quality control consciousness
Compared with other projects, municipal water supply and drainage has a strong specificity, mainly for the special nature of the construction unit, and for the project funds by more than direct allocation of state or local governments. Part of the construction unit during the municipal water supply and drainage construction, quality control consciousness of the widespread, but mostly focus on the management of the progress of. part of the construction unit in order to ensure their own interests at the expense contrary to professional ethics in the construction of a large number of low-grade pipe material, altering the pipeline route and other phenomena occur, seriously affecting the construction quality control. In addition, the domestic municipal water supply and drainage construction quality management and control, the construction unit, there are more serious control problems, control the subject is not clear, the department set overlap, and so the lack of specific mandatory standards is extremely common, fundamental analysis, which is the construction unit managers ideological paralysis, the responsibility is not strong, negative work attitudes are closely linked, and thus makes it difficult for the effective construction quality control.

1.2 Construction of a lack of quality control unit
Municipal water supply and drainage construction quality control and management is a system of work, the construction of specific organizational units as the main construction work for construction quality control has not shirk responsibility, but the domestic construction market, a large number of smaller funds, technical weakness of the construction unit of the influx has led to most of the construction unit in the municipal water supply and drainage construction, a lack of quality control there are drawbacks. In addition, part of the construction contract as a whole unit does not have an independent water supply and drainage projects, qualifications and ability, and had to take sub-contract or sub-form of this phenomenon virtually increase the project to the Project Management department for quality control difficult , can easily lead to the phenomenon of poor quality construction.

1.3 Project Management is not in place
In the municipal water supply and drainage construction quality control, the supervision unit during the construction quality supervision and management, to outside interference and influence more, leading to the widespread problem of supervision is not in place. In addition, because municipal water supply and drainage works organized by the government infrastructure projects, the construction unit to use the special nature of the project, refuses or fails to actively cooperate with relevant work supervision units for municipal water supply and drainage project construction quality control adverse effects.

Lack of standardized management 1.4
In recent years, for municipal water supply and drainage construction in the common quality control problem, the state has issued a series of specific management practices and systems, but because of the government's lack of supervision and management efforts, resulting in the formation of a lack of standardized management of the status quo. Part of the city water supply and drainage project construction, administrative or municipal departments to carry out drainage works in the bidding, the lack of legal system for the project, the bidding system, contract management, project supervision system of standardized management, ultimately resulting in construction quality control issues continuous exposure.

2 strengthen the municipal water supply and drainage construction quality management and control measures
Municipal water supply and drainage construction quality management and control is an important social problem, but also to the overall urban construction and development. For the domestic municipal water supply and drainage project construction quality control of the situation, government administration and municipal authorities must be accountable to the people has never been point of view, enhance the quality of the whole process for the construction supervision and management of three-dimensional, while water supply and drainage project construction unit will have a profound understanding of the importance of strengthening quality management, and thus full realization of the project's economic benefits and social benefits.

2.1 The focus of the review design drawings and technical tests
Municipal water supply and drainage projects in the pre-construction, construction units with construction units, design units, supervision units together on the design drawings of the audit, especially to technical problems for which to explore and research, and ultimately the formation of scientific and practical construction Technology program. In addition, according to the municipal water supply and drainage construction of the actual needs of the construction unit to the structure for water supply and drainage, location, type, pipe diameter, direction, length, slope, size, depth and well-digit to conduct a comprehensive understanding of construction quality management and control to provide a scientific protection.

2.2 The strict implementation of relevant national quality control standards
Municipal water supply and drainage is a key state regulation of urban construction projects, the State has a strict quality inspection standards in the municipal water supply and drainage works in construction quality control, quality control personnel to in-depth understanding and familiarity with relevant national quality standards based on the construction of the whole process of strict supervision and management in the municipal water supply and drainage construction, once discovered the phenomenon of illegal operations or shoddy work, quality control personnel in time to stop, and reported to Project Management, supervision and development of reform proposals as soon as possible and improvements.

2.3 to enhance the quality of the test pipe installation
In the municipal water supply and drainage construction, construction unit according to design a reasonable choice of acceptable quality pipe materials, and conduct a comprehensive inspection of its quality due to municipal water supply and drainage requirements for pipeline life is generally more than 20 years, so it must to the pipe material impermeability, resistance to stress strict inspection process used to prevent serious quality problems such as leakage or deformation in the municipal water supply and drainage construction, water supply and drainage installation process is standard, For the construction quality control has important implications, therefore, the construction unit should strengthen for the specific installation aspects of quality control, in particular, should pay attention to flexible pipe laying problems, a comprehensive analysis of load, the ring stiffness and other factors, and thus to strengthen the pipeline installation quality control.

2.4 and gradually establish a unified standard of construction quality supervision
At this stage of municipal domestic water supply and drainage construction supervision work, the supervisors of professional work are still relatively low, has not yet formed a unified supervision of construction quality standards. Municipal water supply and drainage construction supervisors in supervision of construction experience in different projects the sum and summary of the basis, and actively communicate with their peers, exchange, common research, discussion, and ultimately to develop a municipal water supply and drainage for domestic construction supervision of a unified Industry standard, and actively promoting the various water supply and drainage supervision unit and construction unit, in order to guide the Industry to achieve healthy, stable and sustainable scientific development goals.

3 Conclusion
In short, in the municipal water supply and drainage construction quality management and control, construction units, design units, construction units, supervision unit must first establish a serious and responsible work attitude and rigorous style, to ensure construction quality control capability and raise the level of ideas and knowledge base. In addition, because municipal water supply and drainage project involved the construction project, which is why only for each specific part in strengthening quality management and control, based on in order to effectively prevent the municipal water supply and drainage in a variety of common construction quality problems, to enhance our quality of municipal construction of drainage works.
