Application of Sponge-type Rainwater Inlet in Urban Road Design
In the design of urban road sponge cities,corresponding sponge facilities should be selected according to the width of green belt,road cross slope and surrounding conditions of different sections.The common practice is to set sunken green space or biological detention zone in combination with side and middle zones for rainwater collection and dissipation;When there is no side and middle separation,the sponge facilities available are often limited.Taking Zhenxing Road in Zhengzhou City as a case,this paper expounds the application of sponge-type rainwater inlet combined with tandem tree pond in urban road sponge city design,which can be used for reference by other regional design peers.
