摘要
城市排水泵站的设计易受用地面积、进出水管网排布、周边地形条件及施工要求等多方面影响,实际设计时常难以满足常规泵站设计规范中水力条件良好的要求。对城市泵站前池进水流动特性进行分析,并对目前泵站整流技术进行总结,归类为5种技术:导流墩整流技术、导流栅整流技术、底坎整流技术、压水板整流技术和配水孔整流技术。给出各方法的工程应用现状,并详细对各方法优缺点及适用范围进行了分析,为提高城市泵站系统运行可靠性提供参考。
Design of urban drainage pumping stations is susceptible to land area,water pipe network layout,surrounding terrain conditions and construction requirements.It is often difficult to meet the requirements of favourable hydraulic conditions in the design specifications of general pumping stations.This paper analyzes the inflow characteristics of the forebay of urban pumping station,summarizes and classifies the existing rectifier technology of the pumping station into five types such as diversion pier rectifier technology,diversion grid rectifier technology,bottom sill rectifier technology,pressure plate rectifier technology and water distribution hole rectifier technology,and introduces the engineering application status of each technology,and the advantages,disadvantages and applicable scope of each technology in detail,which can provide reference for improving the reliability of urban pumping station system.
