高压喷射注浆止水帷幕加固三峡隔流堤技术

CONSOLIDATION TECHNIC OF HIGH-PRESSURE INJECTING GROUTING IN WATER SEAL WALL OF THREE-GORGE PROJECT

采用高压喷射注浆在三峡隔流堤A区施工止水帷幕 ,之后出现多处渗漏 ,经分析查明原因后提出两种处理方案 ,综合比较两种方案 ,最后决定修改部分技术参数 ,仍采用高压喷射注浆进行补强试验 ,试验证明效果良好 ,可以在整个A区推行高喷补强方案。为了确保三峡工程的顺利施工 。

This paper analyses the leakage of area A of GJ weir of the three\|Gorge project,and two available consolidation measures are put forward.The test shows that reinforcing high\|pressure injecting grouting is successful,and the life\|span of water seal wall is discussed.
