摘要
文中以佛山市银桂路雨水系统为例,运用能量方程,以雨水排放管末端水系水位为控制高程,采用谢才公式计算压力淹没出流工况下雨水管道的水头损失,进而推算设计内涝重现期下道路易涝点液位,通过控制易涝点液位低于地面高程,满足内涝防治要求.该案例旨在为道路雨水系统的内涝防治设计提供借鉴.
Abstract
Taking the rainwater system of Yingui Road in Foshan City as an example,the energy equation was used to calculate the head loss of the rainwater pipeline under the condition of pressure inundating outflow by taking the water level at the end of the drainage pipe as the con-trol elevation,and the Xecai formula was used to calculate the water level at the Lewi waterlogging point in the design waterlogging recurrence period.By controlling the water level at the waterlogging prone point to be lower than the ground level,the requirements of waterlogging preven-tion and control were met.This case aims to provide a reference for the design of waterlogging control in road stormwater system.
