探析基于海绵城市理念的市政既有道路改造施工技术

Discussion on the Construction Technology of Existing Municipal Road Reconstruction Based on the Sponge City Concept

针对市政既有道路改造施工,提出了结合道路现状确认改造方案以及“海绵”设施设计、溢流口布置的主要问题。根据案例道路原状进行施工改造处理,解决了既有道路基础设施不足、排水的问题,实现了从人行道、绿化带、路面进行雨水渗透与排出。案例分析结果表明,在市政既有道路改造中引入海绵城市理念,不仅能缓解城市内涝的问题,还可提高道路绿化率、保护土地,充分收集利用雨水资源。

According to the reconstruction construction ofexisting municipal roads,the paper puts forward the main problems of confirming the reconstruction scheme,the design of“sponge”facilities and the layout of overflow.According to the original state of the road,the construction and renovation treatment have solved the problems of insufficient existing road infrastructure and drainage,and the rainwater infiltration and drainage from the sidewalk,green belt and road surface are realized.The result of case analysis shows that the concept of sponge city can not only alleviate the problem of urban waterlogging,but also increase the greening rate of roads,protect land,and fully collect and utilizerainwaterresources.
