小江水库2~#副坝渗流不稳定,严重威胁水库大坝的安全。利用高喷灌浆技术对水库进行除险加固,时其主体工程防渗板墙设计采用单排折线连接,分两序孔进行施工,取得良好效果。
The 2 ~ # sub-seepage flow in Xiaojiang Reservoir is unstable and threatens the safety of reservoir dam seriously. Using high-pressure grouting technology to reinforce the reservoir for reinforcement, the main engineering anti-seepage wall design using single-fold line connection, two holes were constructed, and achieved good results.
