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 compounding in a circular pipe network for village life and fire water. The design of the residential area according to Class-1 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 community water supply and drainage network 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; network layout; water supply pipe; sewage pipe; raining pipe 摘要 Ⅰ 目次 Ⅲ 术语表 Ⅴ 1引言 1 1.1 工程概况 1 1.2 管线综合设计 1 1.2.1 平面布置 2 1.2.2 竖向布置 2 1.2.3 管线之间遇到矛盾时的处理原则 2 2 给水管网设计 3 2.1 给水管网设计依据 3 2.1.1 给水方式 3 2.1.2 给水管网布置与敷设措施 3 2.1.3 设计用水定额 4 2.1.4 用水量变化 4 2.1.5 管网水力计算的流量 5 2.1.6 管径计算 6 2.1.7 管网水头损失计算 7 2.2 小区市政给排水管网设计 7 2.2.1 给水方式 7 2.2.2 给水管网布置与敷设 7 2.2.3 给水管网设计并计算
