Application of“sponge city”concept in raod drainage design

介绍了位于官厅水库二级保护区内的西玉路排水工程设计,按照保护水体的要求,避免由于排水设计不当导致水体的污染;依据相关设计规范,运用海绵城市设计理念,并因地制宜地采用管道贮存方式代替常规的应急池设计方案,节省了用地、减少了投资。

This paper introduced the design of drainage network of Xiyu Road in the secondary grade preserve of Guanting Reservoir. According to the requirements for water protection, the wa- ter pollution caused by improper drainage design should be avoided. In light of design codes, the design concept of ＂sponge city＂ was used; in addition, on the basis of real circumstances, the pipe storage method was employed instead of the traditional emergency tank method. In this way, both the land and the cost were saved.
