摘要
针对我国目前雨水利用现状,分析了硬化路面雨水收集的需求。根据我国城市排水设施及道路建设情况,认为实施硬化路面雨水收集具有可行性,并可在一定程度上缓解城市内涝问题。以青岛市平度地区为例,采用扣损法对2009年6—9月雨水可收集量进行了估算,若集雨路面达50%,则汛期可集雨量为543万m3,经济收益将超过1 357.5万元。城市硬化路面集雨潜力巨大,值得重视和发掘。
In view of China＇s current situation of rainwater utilization,this paper analyzes the requirement of impervious road surface rainwater collecting.The rainwater collecting project is feasible,and it can alleviate waterlogging problem according to urban drainage and road construction condition of China.Take Pingdu of Qingdao as a research area,it estimates a rainfall collecting potential from June to September of 2009 by deduction method.If the road surface of rainwater collecting reaches 50%,the flood season rainfall can be set to 5.43×106 m3,the economic benefits will exceed RMB 13.575 million.Urban rainwater collecting project which has great potential and is worth to pay attention and explore.
