The design area is outdoor water drainage pipelines within the scope of the red line of the load. The housing district is located in the suburbs, tap water supply source by city for introducing two road water pipes pounding in a circular pipe work for village life and fire water. The design of the residential area according to Class1 residential includes rain and sewage drainage system. Community rain water outside the municipal district final goes to rain trunk sewers. The drainage system in the district adapts shunting system of rain and dirty water. According to the principle of the current national design, construction standards and the principle of the general plan which provides professional design and general information on original pipeline layout I chose the reasonable plan. And then I explain the using pipes, the embedding depth, the form of interface and gully. Finally, I check the arrangement of Penstock and design of water supply, sewage and rain system. And I do some hydraulic calculation to the supplying water, dirty water and raining water. To meet the need of people living in the environment, ensure the safety of munity water supply and drainage work and for the sustainable development of environmental protection, rational distribution, we should create a beautiful environment, a new residential district facility. Key words： hydraulic calculation。 work layout。 water supply pipe。 sewage pipe。 raining pipe III 摘要 ..........................................................................................................................................
