摘要
我国正处于城市化快速发展的关键阶段,城市建设作为城市化发展的重要部分,其中城市不透水面积剧增,管道的传统排水方式导致道路排涝压力大、路面污染严重等问题越来越突出,在很大程度上影响到城市建设中生态环境的可持续发展。针对这些问题,海绵城市理念的提出以及在城市道路排水设计中的应用,能够实现对雨水的滞蓄、净化、回用,大大提高了城市排水效率,有效缓解城市内涝。文章在海绵城市理念的基础上分析海绵理念的开展对道路排水设计的积极意义,在剖析目前我国城市道路传统排水现状的同时,针对性地提出基于海绵城市概念下的道路排水设计思路,希望能够为我国海绵城市建设过程中的项目设计提供一定的参考。
China is at the critical stage of rapid urbanization.Urban construction is an important part of urbanization development.The increase of urban impervious area and the traditional pipeline drainage method lead to outstanding problems such as large road drainage pressure and serious road pollution.It greatly affects the sustainable development of the ecological environment in urban construction.In this case,the proposal of the sponge city concept and its application in the urban road drainage design can realize the stagnation,purification and reuse of the rainwater,which greatly improves the urban drainage efficiency and effectively alleviates the urban flooding.Based on the concept of sponge city,this study analyzes the positive significance of road drainage design,analyzes the current status of traditional urban road drainage in China,and proposes corresponding road drainage design.It can provide certain reference for the project design during the construction of sponge city in China.
