浅析海绵城市工程建设中透水混凝土的应用及质量控制

为提升城市生态系统功能和减少城市洪涝灾害的发生,国家大力推进海绵城市建设,《关于推进海绵城市建设的指导意见》明确提出,“通过海绵城市建设,最大限度地减少城市开发建设对生态环境的影响,将70%的降雨就地消纳和利用”。透水混凝土以绿色地面建筑材料的形式出现,这种新型环保材料不仅具有防水、防滑、防腐等优点,而且具有良好的渗透性,适用于道路施工,可以更好地减少道路积水。本文阐述了透水混凝土的特点及适用范围,并以虎仔山西路工程项目为例,分析透水混凝土的施工工艺。

In order to improve the function of urban ecosystem and reduce the occurrence of urban flood disasters,the state vigorously promotes the construction of Sponge City.The Guiding Opinions on Promoting the Construction of Sponge City clearly puts forward that"through the construction of Sponge City,the impact of urban development and construction on the ecological environment shall be minimized,and 70%of rainfall shall be absorbed and utilized locally".Permeable concrete appears in the form of green ground building materials.This new environmental protection material not only has the advantages of waterproof,anti-skid and anti-corrosion,but also has good permeability,which is suitable for road construction to better reduce road water-log.This paper analyzes the characteristics and application scope of permeable concrete,and elaborates the construction technology of permeable concrete by taking Huzi Shanxi road project as an example.
