细砂层防渗墙施工中泥浆改良及应用

Improvement and Application of Cutoff Wall Slurry Construction in Fine Sand Layer

混凝土防渗墙施工时为避免塌孔和增加防渗性,常用泥浆固壁,因此实际施工中对泥浆的应用和控制显得尤为重要。文章结合工程实例,对固壁泥浆的作用、泥浆性能改良、与拌制方法进行了阐述。

In order to prevent holes from collapsing and increase the seepage-proofing capability in the construction of concrete cutoff wall,the method of slurry protection wall is used commonly.Based on the engineering project,the effect of slurry protection wall,the improvement of slurry performance,and the mixing method is introduced.
