Application of Waterlogging Control in Road Stormwater System
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.
