摘要
分析黄河公伯峡水电站左岸泄洪洞混凝土施工结构缝渗漏及产生裂缝原因,对渗漏进行化灌处理,处理后的结构伸缩缝和裂缝均达到不渗漏的效果,施工质量满足设计要求。
The paper analyzes the crack seepage in concrete structural joints of the spillway tunnel on the left bank of Gongboxia hydropower station on the Yellow River and the causes of cracks. Chemical grouting was carried out against the seepage, and no leakage occurs in the structural expansion joints and cracks after treatment. The construction quality satisfies the design requirements.
