凌津滩水电站坝体横缝漏水化学灌浆处理

Chemical Grouting Treatment to Leakage in Transverse Joints inside Dam Body of Lingjintan Hydropower Station

凌津滩水电站二期工程 ,其坝体横缝止水片附近混凝土因浇捣不密实 ,出现脱空现象 ,灌浆廊道内坝体横缝漏水。经采用化学灌浆方法对漏水缝及点进行止水处理 。

Due to insufficient vibrating compaction in concrete pouring ,there occurred cavity pockets in the concrete near the copper sheet seal in the transverse joints inside the dam body of 2nd stage project of Lingjintan Hydropwer Station.Through the sealing treatment of the leakage joints and points by using chemical grouting ,it was approved that the method is quite effective.
