破损道路混凝土基层压密注浆加固施工技术分析

Construction Technology of Compaction Grouting Reinforcement for Damaged Old Road Concrete Base

文中以杨集镇潮河春晓新型社区建设项目改造为例,该项目旧混凝土路面改造工程,利用高压泵将配制好的水泥浆液注入需补强加固的砼路面板底脱空空隙和被水软化的地基层中,达到增强路面下结构层稳定性和固化路基的作用。

This paper takes the reconstruction of ChaoheChunxiao new community construction project in Yangji Town as an example.In the reconstruction project of old concrete pavement,the high pressure pump is used to inject the prepared cement grout into the void of concrete pavement bottom which needs to be reinforced and strengthened and the base which is softened by water,so as to enhance the stability of the structural layer under the pavement and solidify the subgrade.
