摘要
排水管网是现代化城市和工业区不可缺少的一项重要基础设施,同时也是控制水污染、改善和保护环境的重要工程措施。
本设计是关于山西省某县县城排水工程的管网设计,它包括污水排水系统和雨水排水系统的布置。某县采用对比法确定排水体制选用污水、雨水分流布置形式。污水排水系统的管网设计的内容包括划分排水面积,布置管道系统;根据设计人口数、污水定额,计算污水设计流量;根据污水水力计算图进行污水管道的水力计算,确定管道断面尺寸、设计坡度、埋设深度等设计参数;确定污水管道在道路断面上的位置;绘制管道平面图和纵剖面图。雨水排水系统的管网设计的内容包括划分排水面积,进行雨水管渠定线,确定出水口的位置;划分设计管段,计算各管段设计流量;根据雨水水力计算图进行雨水管渠水力计算,确定管渠的断面尺寸、坡度、标高及埋深等设计参数;绘制管渠平面图及纵剖面图。
排水管网设施建设的好坏,直接决定着城市的发展水平,影响着城市景观和环境卫生,影响着城市品位和投资环境,甚至关系到城市的安全。

ABSTRACT
work is an important indispensable infrastructure of modern cities and industrial areas, and it is also one of the important measures to the water pollution control and environmental protection.
This design is about the drainage work engineering project about the H County of Shanxi Province in china. This project includes sewage and storm-water drainage system layout of the drainage system. H County use contrast optional to determine the form of sewage drainage system and water diversion layout, Sewage drainage system in the pipeline includes the design of drainage area and layout pipeline system; According to the population of this area and sewage fixed, The author calculates the sewage flow design; Based on Hydraulic calculation plans to calculate the sewage effluent pipe hydraulic calculation, we can determine pipeline section size, design slope, and planted depth of the design parameters; Determine sewers in the road section on the location; Draw floor plans and vertical section pipeline plans; Draw floor plans and vertical section of the drainage on Hydraulic calculation to calculate the rain water map of Qushui calculation, we can determine the pipe section size, slope, elevation and depth and other design parameters.
is an important and basic installation in modern cities and industrial estate , meanwhile it is a major project measure which could control water pollution an improve the environment . Storm-water
