渗滤排水方式在道路设计中的运用研究

摘要:

路面径流中含有一百多种污染物，直接排放会对地表受纳水体会产生污染，同时随着城市化进程的加快，大部分城市存在着城市内涝问题。如何避免或减轻路面径流对受纳水体造成的污染，同时减轻城市的内涝问题是新时期道路设计的研究方向。本文基于生态环保和切实可行的原则，在分析渗滤介质对路面径流净化处理效果的基础上，结合海绵城市设计原理，在道路设计中提出了路面径流渗滤排水系统设计思路，最后针对不同的路段形式，分别提出相应的渗滤排水方式。

Abstract:

There are more than one hundred kinds of pollutants in road runoff. Direct discharge will pollute the surface receiving water body. At the same time, with the acceleration of urbanization, most cities have the problem of urban waterlogging. How to avoid or alleviate the pollution caused by road runoff to the water body and alleviate the problem of urban waterlogging is the research direction of road design in the new era. This article is based on the principle of ecological environmental protection and practical, on the analysis of the percolation medium for road surface runoff purification treatment effect, on the basis of combining the sponge principle of urban design, supervision of the pavement in the road design runoff infiltration drainage system design model, finally according to different forms of roadbed, respectively, put forward the corresponding ways of infiltration and drainage.
