摘要
基于海绵城市理念,结合某工程实例,论述了城市排水工程的详细设计构思,给出了调蓄容积、年径流量控制率、径流污染削减率等指标的控制原则,通过设置调蓄水池、透水铺装、下沉式绿地等措施落实控制指标,使外排至市政雨水管网的雨水量得到有效控制,体现了工程项目的海绵特质,对海绵城市建设具有一定的示范作用.
Based on the concept of sponge city and a project case,this paper discusses the detailed design idea of urban drainage project students,and explores the control principles of regulating volume,annual runoff control rate,runoff pollution reduction rate and other indicators.Indicators are implemented by setting up regulating reservoir,permeable pavement,sunken green land and other measures to effectively control the amount of rain water discharged to the municipal rainwater pipe network,which reflects the sponge characteristics of the project and has a certain demonstration effect on the construction of sponge city.
