摘要
本文主要探究了下沉式道路排水系统的设计要点。在设计中首先要根据径流系数、设计暴雨强度等参数,计算下沉路段的雨水设计流量。同时结合实地勘察判断下沉式路段的类型,对于两个或多个连续的下沉式路段,可以在相邻集水点之间布置连通管道,然后在最低集水点处修建泵房进行统一排水,有助于减小工程规模、控制工程成本。从下沉式道路排水系统设计的应用实例来看,该道路的雨水设计流量为1308.6 m3/h,泵房设计流量为1.2倍的雨水设计流量,即1570.3 m3/h。泵房内安装2台额定流量为800 m3/h的潜水泵,可以满足排水需要。
This article mainly explores the design points of sunken road drainage systems.In the design,the design flow of rainwater in the sinking section shall be calculated first according to the runoff coefficient,design rainstorm intensity and other parameters.At the same time,combining with on-site investigation to determine the type of sunken road section,for two or more continuous sunken road sections,connecting pipelines can be arranged between adjacent drainage points,and then a pump room can be built at the lowest drainage point for unified drainage,which helps to reduce the project scale and control project costs.From the application example of sunken road drainage system design,the rainwater design flow rate of the road is 1308.6 m3/h,and the pump room design flow rate is 1.2 times the rainwater design flow rate,which is 1570.3 m3/h.Install two submersible pumps with a rated flow rate of 800 m3/h in the pump room,which can meet the drainage needs.
