混凝土防渗墙是可以适应各种不同材料的坝体以及水文地质条件与工程地质条件的具有防渗功能的连续的地下墙体,其基本做法是借助泥浆的护壁功能,先用造槽孔机在地下开出深而窄的槽孔,然后在槽孔内浇注混凝土,待混凝土凝结后便形成了一道连续的地下防渗墙体。采用这种方法防渗具有施工方便、工程进度快、防渗效果优良、环境副作用小等特点。本文主要介绍了某大坝混凝土防渗墙的施工技术
Concrete impervious wall is a continuous underground wall with impervious function that can adapt to different kinds of dam materials and hydrogeological conditions and engineering geological conditions. The basic approach is to use the function of mud retaining wall, Deep and narrow slots are drilled in the ground, and the concrete is poured into the slots. After the concrete is set, a continuous underground impervious wall is formed. Anti-seepage using this method has the advantages of convenient construction, fast construction, excellent anti-seepage effect and small environmental side effects. This article mainly introduces the construction technology of a dam concrete cutoff wall
