东升电站堆石混凝土重力坝固结灌浆工程

Consolidation grouting engineering of concrete rockfill dam of Dongsheng power station

东升水电站挡水建筑物采用堆石混凝土重力坝,基础固结灌浆过程中发现钻孔施工难度较大,采用了先对抛石段灌浆,后钻孔,再整体固结灌浆的方法,解决了这一问题,提高了整体的施工效率,经检验,固结灌浆效果明显,达到了设计要求。

Dongsheng station uses rockfill concrete gravity retaining structures,it is difficult in foundation consolidation grouting in drilling construction.According to specific circumstances,firstly,we threw stones,grouted,and drilled,then,the overall consolidation grouted solutions to solve this problem.It improves the overall efficiency of construction,and inspection,consolidation grouting effect is obvious,and meets the design requirements.
