[Keywords] municipal roads, drainage works; construction, prevention and management

In China's urban planning and construction, transport facilities are perfect, the actual traffic capacity and traffic inspection and cities are an important indicator of the modernization process, so most cities have accelerated domestic municipal road projects the pace of building, and through Technology, Technology management means constant innovation to achieve a substantial increase in the quality of road works in the construction of municipal road projects, water supply and drainage project is one of the basis for the construction of scientific and effective prevention and management is also essential, but also to ensure municipal road projects key to the overall construction quality.

A municipal road projects constitute the basic drainage system
In the construction of municipal road projects, in order to fully protect the road capacity and further improve the overall road performance and useful life, generally requires drainage design and construction present in the country's municipal road projects, including drainage system : water wells, silt wells, drains and other basic part of the street, in the prevention and treatment of construction management, but also carry out targeted construction quality and technical supervision.

1.1 water wells
Municipal water wells road drainage system is an important part, which is usually referred to as "closed outlet." Municipal road in the country at this stage of the construction of drainage works, common water wells are eighty-six style rain wells, wells with silt double grate, grate four, eight water wells and other types of grate type, the main purpose of the discharge of water on the road a lot, the construction of water wells operating normally in lime and black gravel road between the construction is more appropriate.

1.2 silt well
In the municipal drainage system, the silt and water wells and more wells constructed, fabricated water wells is an important part. Water wells with different functions, the main role of silt wells for surface erosion due to rain brought a lot of silt and garbage deposited or stored for road cleaning staff can clean up in time, effective control of the road drainage system clogged disadvantages and problems. silt well construction operations are generally chosen to curbs and sidewalks installed base after leveling of earth.

1.3 across the street drain
Water wells across the street drains or silt is well connected within the major channel, whose main role is to check the road drainage water into wells present in the domestic municipal drainage project, selected more for the street drainage concrete pipe, the General specifications: diameter 400-450cm, thickness 3-3.5cm, a single length of 1-2m. across the street and drainage construction work generally opt for the construction and laying of lime in the lime-stone between the more appropriate, help to open trench digging and molding.

2 construction of municipal road drainage management measures analysis of control
Construction and development in the city, the municipal road projects is to ensure that the basis for economic development, but also for urban development and the management also has important implications for in municipal road construction, drainage works occupy an important position for the construction of various drawbacks and problems exist for effective prevention and management is crucial, and is to ensure that municipal road performance and safety performance of the basic conditions must be caused by municipal departments and construction units in the project management staff are highly valued.

2.1 Strengthening the construction drawings of the audit
Municipal roads and drainage works in construction management, construction drawings, as a result of lax auditing of quality problems have occurred, often will affect the overall progress of construction and safety, therefore, the prevention and management of drainage construction in the first Yao Jia Jiang drawings for the construction of the audit, 并且 and design units Jinxing detailed technical tests, a comprehensive understanding of the length of drainage works of Guan Xian, pipe specifications, to, slope, well Weishu, as well as Shigongquyu the relevant geological and Shuiwenziliao, Jin Er to drainage works to ensure the orderly conduct.

2.2 strict quality inspection pipe
Municipal roads and drainage works in the construction preparation phase, the focus of management control is strictly tested the quality of pipe, including pipe size, type, diameter, thickness, length, material, corrosion resistance, aging resistance, etc., must be professional technical staff of the coffin of quality inspection in the drainage pipe construction quality inspection, quality inspection departments need to backup vendor certification and mechanical test reports and other relevant Information. Meanwhile, in the drainage pipes installed before the construction of technical personnel but also on the pipe-by-section inspection, if found quality problems should immediately exit the pipe, the pipe shall not be forced to use poor quality in the project.

2.3 to enhance the quality of the management pipeline installation
Drainage works in the municipal road construction, pipeline installation standard is whether the quality of prevention and management of the important projects. Under normal circumstances, the cushion pipe installed in the acceptance level for the base, and ensure the basic part of the required strength. The installation of the drains, the construction unit must select the superior performance of the interface to fill, and in accordance with standard test procedures for different mix of comparison, the construction process to ensure that the organization is reasonable and scientific. Carrying out drainage piping seams with construction of the wipe, the interface must first be cleaned inside seam, if there are more impurities can be used to clear cutting hair treatment. During the discharge tube before the construction workers to the surface of the base debris, mud, water, etc. completely removed, and by repeated measurements to determine the elevation and the elevation of the center model, to ensure that discharge pipeline from the downstream to upstream in turn arranged in the drain pipe under the road, often require the use of large lifting machinery, and by artificial completed, make sure you work under the control of personnel safety. Hoisting machinery to dock at the edge of 2-3m at the ditch to avoid the phenomenon of trench wall collapse, thereby affecting the trench slope stability and security for any inconvenience to use heavy machinery for pipe installation location, you can use manual pressure rope under the control of the method, but to pay attention to the installation location accuracy and robustness.

2.4 good closed water test
Municipal roads and drainage works in construction management in the prevention and treatment, the role of closed water test can not be ignored, it not only can be applied to various types of pipe quality testing, and test results for the quality of construction is also more satisfactory. Water drainage works during the closed trial, in order to ensure the accuracy of test results, usually 3-4 times the need for test if the test found that part of the pipe or pipe joints there is leakage, and marked the surface of the pipe should be , and the water in the pipe completely drained after careful examination, to find leakage points, and make the appropriate treatment for small leakage points or gaps can generally use waterproof paint or cement brushing approach for serious leakage of pipe to rework processing, quality standards and timely replacement of the pipe.

3 on the municipal road drainage construction management of the proposed control
3.1 in municipal road construction, drainage works, municipal departments to organize professional and technical staff, managers set up project management committee and related supervision and inspection departments. Construction unit must actively accept the supervision and management of municipal departments, and with their own set up to meet the actual situation prevention and management of the construction requirements of the institution, and with a sufficient number of managers and technical staff, municipal roads and drainage construction for all-round, three-dimensional, multi-angle management.

3.2 in the municipal drainage prevention and management of construction work, the person in charge of various departments and their responsibilities must be clear and to develop and implement a scientific, objective and operational responsibility of project management positions for construction various types of management, quality, security management responsibilities are refined, to ensure that in the event of an accident, you can promptly organize personnel to remedy or treatment.

3.3 With the concept of domestic municipal project management continues to mature and develop, municipal departments should strengthen their own management from the perspective of the gradual build a scientific, sensitive and efficient prevention and treatment of municipal road drainage management system construction the same time, municipal roads drainage engineering and construction units should pay attention to prevention and management capacity enhancement, and municipal departments in time relevant for comments and suggestions to give feedback, transmission and processing, construction management to create a good atmosphere to raise the overall municipal roads and drainage works construction quality, to protect the city the rapid development of infrastructure.
