基于'海绵城市'理念的生态树池对路面雨水排放的影响

摘要

In many cities of China, the rainstorm waterlogging frequently, by introducing the ecological tree pool, can realize the multiple benefit waterlogging prevention, water resources utilization, landscaping in a certain extent. Based on the Ministry of housing and urban construction SpongeBob urban construction technology guide, low impact development of rainwater system construction ", by water balance method calculation ecological tree pool design parameters, determined under certain conditions of the catchment area, ecological tree pool of runoff reduction rate and different reproduce standard corresponding to the peak flow reductions, and points out that ecological tree pool can improve the regional Pipeline Comprehensive Drainage diversion ability.%我国许多城市暴雨内涝频发,通过引入生态树池,可在一定程度上实现防治内涝、水资源利用、景观美化等多重效益.本文基于住房城乡建设部《海绵城市建设技术指南——低影响开发雨水系统构建》,通过水量平衡法计算生态树池相关设计参数,确定在一定汇水面积条件下,生态树池的径流削减率及不同重现期标准下对应的峰流量削减量,并指出生态树池能很好的改善区域管线综合排水导流能力.
