Guangzhou Municipal Drainage Pipe Application Situation And Development Countermeasure Research

City municipal drainage pipe is very important for the development of modern cityinfrastructure, municipal drainage pipe in the ground, as if the structure of the city life.Municipal drainage pipe is the basis of urban public facilities, and for the protection of thenormal production and living city has very important significance. Guangzhou mega cities asa population of more than12million, the city’s municipal drainage pipeline system has beenbuilt already amounted to more than11000kilometers, the total length of pipe most of usefixed number of year for more than25years. Construction technology level in differentperiod, ground subsidence, pipe quality and pipeline corrosion, and many other adversefactors, the guangzhou municipal drainage pipeline dislocation, fracture, disconnect and evencollapse phenomenon continues to increase, the work of the improvement of the guangzhoucity drainage pipeline, update is imminent. But there are many different kinds of municipaldrainage pipe, this article will find out what kind of drainage pipe material is more suitablefor guangzhou municipal drainage pipeline engineering.theory combining with the actual development zone avenue, Kowloon rain sewagediversion project, small continent beautiful countryside laid drainage pipeline engineeringand drainage hai xihua street reconstruction project such as municipal engineering of thethree specific research, combined with the present situation of the application of theguangzhou municipal drainage pipe, through the analysis of the drainage pipelineconstruction situation, all kinds of pipe material of various performance contrast, throughcalculating methods of research, the main conclusions are as follows:1) Guangzhou municipal drainage pipe network has been used for years, mostconstruction technology level in different period, ground subsidence, pipe quality andpipeline corrosion, and many other adverse factors, the guangzhou municipal drainagepipeline dislocation, fracture, disconnect and even collapse phenomenon continues toincrease, the work of the improvement of the guangzhou city drainage pipeline, update isimminent.2) in guangzhou municipal drainage pipe actual choice should be based on the specific construction environment, the design requirements, etc., through technology, economy,environment and determined after comprehensive comparison. Guangzhou municipaldrainage pipe in the future market will be plastic pipe, pipe and other new type pipe andconcrete pipe market, but the plastic pipe, pipe and other new type of tubing in guangzhoucity has good prospects for development.3) municipal drainage pipe diameter less than the municipal drainage engineering ofDN400, because this kind of project is generally not length of the pipeline laying and choosereinforced concrete pipe or HDPE double-wall corrugated pipe of project total cost is almostthe same, and HDPE double-wall corrugated pipe in such aspects as the constructionenvironment, transportation has great advantages, so in general municipal drainage pipediameter smaller construction environment, recommend the preferred HDPE double-wallcorrugated pipe.4) the municipal drainage engineering, municipal drainage pipe diameter greater thanDN400when drainage pipeline laying length less than1000m, using PE composite steel coilpipe or ordinary reinforced concrete project total cost were similar, and PE single sectionsteel composite winding pipe length is reinforced concrete tube length, can reduce the jointbetween the tube and in such a case, it is recommended to use PE composite steel coil tube.When the drainage pipeline laying length more than1000m, by ordinary reinforced concretepipe drainage is a steel frame with PE composite winding pipe more joints, but still betterthan steel composite winding of a PE pipe drainage project total cost is low, so in this case, itis recommended to use reinforced concrete pipe.
