城市排水系统中竖井结构的应用研究

Application of Shaft Well Structures in Urban Drainage System

城市排水系统中竖井的使用十分普遍。介绍了市政排水系统中的五种竖井结构形式,即跌流式竖井、旋流式竖井、台阶式竖井、堆叠式竖井和螺旋坡道式竖井,总结了各种竖井结构的研究和应用情况,对比了五种竖井结构的特点,分析了竖井卷吸气体的原因。研究结果可为城市排水系统中的竖井结构安全稳定运行提供参考。

Shaft well structures are widely used in urban drainage system.This paper introduces five shaft well structures of municipal drainage system,which are falling flow shaft well,swirling flow shaft well,stepped shaft well,stack shaft well and spiral ramp shaft well.It summarizes the research and application of various shaft well,compares the characteristics of five kinds of shaft well,and analyzes the causes of air entrainment in the shaft well.It aims to provide reference for the safe and stable operation of shaft well structures in municipal water transferring system.
