摘要
瀑布沟水电站工程设计中,拟对坝基岩体及覆盖层采用固结灌浆处理,大规模施工前,先进行灌浆试验,试验采用"孔口封闭、孔内循环、一段灌注法"施工。试验成果满足设计要求。
According to the engineering design, the foundation rock and covering strata must be strengthened by consoli- dation grouting. The grouting work is tested before the dam construction start, and the grouting process is in compliance with ＂blocking up the top of the grouting holes, the grout circulates within the holes, one grouting section be grouted at one time＂. The test result meets the needs of design.
