摘　　要：防渗墙施工用定喷的方式,其本身用在大基坑防渗有弱点,其一是板墙薄防渗效果差;其二是在地下不定因素多,质量不易控制。莲湖泵站基坑开挖采用高喷防渗墙围封阻水,其围封的质量好坏决定了能否如期开挖成功。在施工中采用了一系列的质量控制措施,取得了好的效果。There are weak points in the fixed pressure grouting for cutoff wall at large foundation pit. One, the thin cutoff wall will have a lower leakage control efficiency; second, quality control will be difficult as there are many uncertainties in the underground. So the high pressure grouting cutoff wall was adopted to prevent leakage. A good result was achieved as many quality control measures had been taken during the construction.
