高压喷射防渗墙在千年水库坝基防渗中的应用

Application of the High-pressure Jet Grouting Diaphragm Wall in the Dam Foundation Project of Qiannian Reservoir

千年水库坝基高喷防渗墙施工前先进行高喷灌浆试验,通过对试验过程的控制和试验结果的分析,选取有效的施工参数,调整合理的钻孔孔距,保证了本工程的施工质量,取得了良好的防渗效果。

The high-pressure jet grouting test war condected before constructing the high-pressure jet grouting diaphragm wall in the dam foundation of Qiannian Reservoir. Through controlling the test process and analyzing test results,the effective construction technical parameters were selected;the drilling hole distance was reasonably adjusted;the construction quality of this project had been ensured;and the good anti-seepage effect had been achieved.
