摘要
介绍了三峡工程三期碾压混凝土围堰基岩防渗帷幕的布置、施工程序和施工结束标准 ,以及对施工过程中涌水和浆液失水回浓的处理。通过检查孔的透水率和单位注入量的分析 ,表明灌浆效果明显。
The layout of impervious curtain in foundation rock of RCC cofferdam of TGP (Ⅲ-Phase), the grouting procedure and acceptance criterion of the curtain, the measures for blocking up the fissure water and for preventing water deprived from grout are described. The curtain grouting has achieved obvious effect by comparing the grouting rate with the pervious rate through the inspection holes.
