摘要/Abstract

摘要： 为复查多诺水电站震后大坝坝肩及坝基的防渗性，需在蓄水条件下进行大坝灌浆帷幕质量检查。水下检查孔施工水深达40～69 m，钻孔难度大，综合采用水上浮船平台、潜水技术、水下定位与钻探技术，成功完成了蓄水条件下大坝帷幕质量检查，对类似工程具有重要的借鉴意义。

Abstract: In order to recheck the impermeability of abutments and dam foundation of Donuo hydropow_ er station after the earthquake, it is necessary to check the quality of dam grouting curtain under the re_ servior impoundment condition. The drilling depth of the underwater inspection hole is 40~69 m, and the drilling is difficult. By comprehensively using the floating boat platform, diving technology, underwa_ ter positioning and drilling technology, the quality inspection of dam curtain under the condition of reser_ vior impoundment has been successfully completed, which offers important reference for similar projects.

Key words: grouting curtain, quality inspection, reservior impoundment condition, underwater drilling
