摘要
高压喷射注浆法是把注浆管钻入土层后,利用高压喷射流冲切破坏地基土,使注入的浆液与冲下的土以半置换的方式混合凝结成固体,达到改造土体的一种化学加固的方式。本文主要介绍了此法在帷幕施工中的应用。
High-pressure injection and grouting is to use high-pressure injection flow in the grouting pipe to cut the foundation soil.It is a chemical strengthening method of mixed the grouting serosity with soil to rebuild soil structure.This paper introduces the application of this method in purdah construction.
