引水发电洞施工质量通病防治及效果监测分析

Analysis of Headrace Tunnel Construction Quality Defect Prevention and Effectiveness Monitoring

恰甫其海水利枢纽工程针对引水发电洞工程在衬砌时容易出现施工缝渗水、顶拱脱空、结构缝止水漏水、混凝土裂缝等质量通病,采取相应防治措施,在施工中进行逐项落实和检查,有效解决了水工混凝土病害问题,达到了预期效果。

Corresponding control measures are adopted in Qiapuqihai Water Project aiming at construction joint water seepage, crown void, water seal leakage in structure joint, concrete joint and other quality defects which are easily produced in building headrace tunnel project. The control measures are implemented and checked one by one in construction, thereby effectively solving defects of hydraulic concrete problems and achieving desired effect.
