摘要
贵州猫跳河四级窄巷口水电站水库,岩溶严重渗漏,达30多年。虽然经过多次和多洞口的封堵处理,效果不佳,其渗漏流量仍有15m3/s左右。针对此情况,提出了分阶段实施封堵的方案。一期工程针对窄巷口河段的3个主要岩溶漏斗,进行局部永久性封堵。为此,进行了补充勘测:采用瞬变电磁仪,在窄巷口库段,以及进水塔前溶洞附近进行了物探勘测,并取得了成果。
The seepage from karst is quite serious in the reservoir of zhaixiangkou Hydropower Station on Miaotiao River in Guizhou Province for over 30 years. After anti-seepage treatments for many times, the seepage flow is still about 15m^3/s with the poor treated effects. Under this condition, the anti-seepage in stages is put forward, in which the local permanent sealings are planned to be made for the three main karst funnels therein. For this, supplementary prospecting are carried out with transient electromagnetic meter on the reservoir section of the narrow valley and area near the karst eaves in front of the intake tower during the phase I Project, and then the relevant achievements are got as well.
