| 摘 要： | 双液注浆法是在止水帷幕的渗漏处钻孔,找到基坑止水帷幕的渗漏通道,把一定浓度的水玻璃溶液及水泥浆溶液的混合液注入渗漏通道中,水玻璃与水泥浆的混合液快速凝结、迅速封住渗漏通道,起到隔水的作用.其施工步骤为成孔→找渗漏通道→双液注浆→巩固.文章还列举了天津地区采用双液注浆法处理基坑渗漏的两则案例.

| Abstract: | The bi-slurry grouting method is referred to drilling hole at water seepage area at the water blocking curtain to find out seepage channel then grout the mixture of water glass solution and cement slurry into the channel.The mixture consolidates and blocks the channel rapidly and the seeping water is stopped.The operation step is boring hole-finding out seepage channel-bi-slurry grouting-consolidating.Two cases of water blocking with bi-slurry grouting for construction base pit in Tianjin area are cited in the paper. |
