一、前言青铜峡水利枢纽工程是黄河综合利用梯级开发的第一期大型水利工程之一。在施建过程中,曾以甲凝进行基岩裂缝和灌浆廊道排水泵房裂缝的灌浆处理,采用环氧贴橡皮封护裂缝和丙凝灌浆堵水等技术,都取得一定效果。用环氧贴橡皮在水上部位至今完好,但在灌浆廊道中已有多半出现鼓泡脱落,用丙凝灌浆的裂缝也有些部位出现凝胶体 I. INTRODUCTION The Qingtongxia Water Control Project is one of the first large-scale water conservancy projects developed for the comprehensive utilization of the Yellow River. In the process of construction and construction, the grouting treatment of cracks in bedrock and drainage pumping rooms in grout corridors was performed with Jiading, and techniques such as the use of epoxy-paste-rubber-sealed protection of cracks and prop-aggregate grouting were all achieved. Epoxy rubber was used on the water to ensure that it was still intact, but most of the blisters fell off in grout corridors. Gel was also found in some parts of grouts filled with propylene gel.
