街道雨水口常沿道路边沟按一定间距设置,以使路面雨水进入沟管。由于雨水口布置不恰当,常造成路面积水。本文对暴雨时由于雨水口截纳水量不足而引起的路面淹水现象进行了分析探讨,提出了计算雨水口进水量的数学模式,并对各种道路及广场的雨水口间距设计提出了具体的水力计算办法。 Street sluice gates are often set along the road side ditch at a certain distance so that road surface rainwater can enter the ditch pipe. Due to the improper layout of the gully, it often causes road area water. This paper analyzes and discusses the phenomenon of road flooding caused by insufficient water intercepted by the stormwater during heavy rainfall, and proposes a mathematical model for calculating the water intake at the stormwater inlet, and proposes concrete designs for the spacing of the rainwater ports for various roads and squares. Hydraulic calculation method.
