海绵城市中市政道路设计的几个细节处理

Several details of municipal road design in sponge city

最近的几年,一到夏天雨季到来,一些城市就出现内涝问题,人们生活受到很大的影响,生命和财产安全受到严重的威胁。当前的城市的内涝和城市市政道路建设有着紧密的联系。为方便日常交通行走,城市建筑以外的地面多作硬化处理,形成道路与广场,其中道路占绝大部分。结果整个城市的屋顶、道路、广场,全不透水,于是城市排水成为难题。并且当前城市道路建设,在设计施工整套思路上,尽力不让雨水渗透,以保证道路质量。因此当城市出现较大雨水降水时,就会出现内涝现象。基于此,在城市道路建设中利用海绵城市建设理念,对雨水进行吸收以及渗透,城市的内涝发生几率得到很大的降低.本文主要对为了实现海绵城市的市政道路的设计进行分析,提出若干措施。

in recent years,when the rainy season comes in summer,some cities have the problem of waterlogging,people's life is greatly affected,and the safety of life and property is seriously threatened.The current urban waterlogging is closely related to the urban road construction.In order to facilitate daily traffic walking,the ground outside urban buildings is hardened to form roads and squares,in which roads account for the vast majority.As a result,the city's roofs,roads,squares and squares are impervious and drainage becomes a problem.And the current urban road construction,in the design and construction of the whole train of thought,try not to let Rain Water infiltrate,to ensure the quality of the road.therefore When large Rain Water precipitation occurs in cities,waterlogging will occur.Based on this,using the concept of sponge city construction in urban road construction,Rain Water is absorbed and infiltrated,and the probability of urban waterlogging is greatly reduced.This paper analyzes the design of municipal roads in sponge cities and puts forward some measures.
