市政给排水管道布置的设计原则与技术分析

Design Principles and Technical Analysis of Municipal Water Supply and Drainage Pipeline Layout

为了提升市政给排水设计水平,总结了给排水管道布置的基本原则和设计目标,分析了排水体制、雨水设计流量、污水设计流量的确定方法,从技术和经济两方面对比了不同给排水管道材料。同时,分析了给排水管道的纵向和横向布局方法,研究成果表明市政给排水管道竖向布局应控制好管道埋置深度和交叉方式,横向布局方式应根据地形和道路条件选择确定。

In order to improve the level of municipal water supply and drainage design,the basic principles and design objectives of water supply and drainage pipeline layout were summarized,and the determination methods of drainage system,rainwater design flow rate,and sewage design flow rate were analyzed.Different water supply and drainage pipeline materials were compared from both technical and economic aspects.At the same time,the vertical and horizontal layout methods of water supply and drainage pipelines were analyzed.The research results showed that the vertical layout of municipal water supply and drainage pipelines should control the burial depth and crossing mode of the pipelines,and the horizontal layout method should be selected and determined based on the terrain and road conditions.
