市政工程基坑施工中高压喷桩技术的运用

On application of high-pressure jet-grouting pile technique in municipal foundation pit construction

介绍了高压喷桩技术的特征、优点及适用范围,从防渗墙施工、现场检测、施工检查等方面,阐述了高压喷桩技术在市政工程基坑施工中的应用,指出高压喷桩施工震动频率小、噪声小、操作方便,具有广阔的应用前景。

The paper introduces the features,advantages and applied scopes in the high-pressure jet-grouting technique,illustrates its application in the municipal foundation pit construction from the anti-leakage construction,site inspection and construction checking,and points out the tech-nique has small seismic frequency and noise and it is easy to operate,so it has broader application.
