市政道路排水系统中雨水调蓄设施的设计与研究

Design & Research of Rainwater Storage Facilities in Municipal Road Drainage System

雨水调蓄池是一种常见的径流污染控制及雨洪调控设施,通常设置在区域的雨水排放系统中。海绵城市的设计理念要求市政道路的排水系统对于雨水不再是简单的速排,还需对雨水进行净化、调蓄。以厦门市海沧区某道路改造工程的雨水调蓄设计为例,将传统雨水调蓄设施与市政道路排水系统相结合,介绍分散式的雨水调蓄设施在道路排水系统中的应用,以及设计要点。

Rainwater storage tank is a common facility for runoff pollution control and flood control,which is usually set in the rainwater drainage system of the region.The design concept of sponge city requires that the drainage system of municipal roads is no longer a simple rapid drainage of rainwater,but also need to purify and store rainwater.Taking the design of rainwater regulation and storage for some road reconstruction project in Haicang District of Xiamen as an example,combining the traditional rainwater regulation and storage facilities with the municipal road drainage system,this paper introduces the application of the decentralized rainwater regulation and storage facilities in the road drainage system,as well as the key points of design.
