摘　　要：郑州市轨道交通10号线一期工程车辆基地周边市政管线尚不完善,为减少车辆基地雨水外排流量,车辆基地根据海绵城市相关要求,设置下沉式绿地及蓄水池,并结合车辆基地各部分功能及雨水流量特点进行分区,雨水量分区内部消化,多余水量统筹调蓄,调蓄后车辆基地雨水出口流量在市政雨水管线承受能力之内。The municipal pipelines around the vehicle base of Zhengzhou rail transit line 10 phase I project are not perfect.In order to reduce the rainwater discharge of the vehicle depot,the vehicle base sets up sunken green space and reservoir according to the relevant requirements of sponge city,and divides the areas according to the functions of each part of the vehicle base and the characteristics of rainwater flow.The rainwater is digested in the area,and the surplus water is regulated and stored as a whole.After storage,the rainwater outlet flow of vehicle base is within the bearing capacity of municipal rainwater pipeline.
