某水电站安装间结构缝渗漏处理设计

Structural Joint Seepage Treatment for Erection Bay of Hydropower Station

某工程厂房上游基坑充水后,电站安装间结构缝因施工质量等缺陷而发生严重的渗(漏)水,为确保电站的安全稳定运行,必须对其进行封堵处理。处理方案:在止水上游侧钻孔灌浆封堵,在两道止水间充填灌浆以恢复止水功能,以及辅以嵌缝等,实施后效果良好。

Serious seepage is found at structural joint of erection bay due to engineering quality defects after water fills upstream foundation pit of the power house at a hydropower station, and must be plugged for the safe and steady operation of the station. At the upstream side of water stop holes are drilled, and grouting is applied between two water stops so that water stop works again. In addition, caulked joint is dug. Thanks to these efforts, the problem is solved.
