摘要
塘口水电站大坝基础座落在断层和裂隙较发育的龟裂纹灰岩上,岩体完整性差、透水性强,多年运行后,大坝灌浆廊道和排水廊道出现多处集中性漏水,为确保大坝安全和电站正常发电,根据渗漏性质和成因,采用对灌浆廊道补充帷幕灌浆,对排水廊道进行固结+帷幕+回填灌浆。通过灌浆处理后,效果良好,表明灌浆工程有效的将导致坝基渗漏的上下游的裂隙通道封闭,并顺利的经受了随后的汛期洪水考验,大坝安全得到保障。
The TangKou hydropower station is based on the chap ash-rock,which develops much fault and cranny,the integrality of rock body is poor and the penetrate ability is strong,the influence of the construct quantity and long time run,many central leakage appear in the grouting gallery and drain gallery of the dam.For the safety of the dam and generating electricity of the station normally,on the basis of analyzing different cause of the leakage,adopting supplementary grouting concretion in the grouting gallery a...
