摘要
以长沙市某城市道路雨水口设计为例,在常规市政雨水管渠设计的基础上布置雨水口(P=3a),防涝标准降雨强度下(P=50a)道路竖曲线底部处雨水口形成孔口流。复核了雨水口的排水能力,并采用SWMM排水模型进行了验证。结果表明,孔口入流条件下,道路竖曲线底部雨水口可满足路面排涝要求。
done based on c standard rainfall Taking design of a road gully in Changsha City as an example onventional municipal rainwater pipe channel design （P = 3 a , a layout of gully was ）. Under waterlogging intensity （P = 50 a）, orifice flow was formed for gully at the bottom of road vertical curve. The drainag results showed that drainage. e capacity was checked, and the SWMM discharge model was used to validate. The the gully at the bottom of the vertical curve could meet the requirement of road
