温峡口水库是全国首批重点病险水库之一 ,大坝存在严重的渗漏破坏问题 ,多次直接灌浆试验均未获成功 ,曾多年做过多种工程方案的比较 ,因大多存在经济或技术上的困难而未付诸实施。提出采用高压喷射灌浆技术建筑一定高度的连续高喷墙体 ,截断基岩表层裂隙和强风化层的渗漏并形成灌浆盖板 ,进而实施基岩防渗帷幕灌浆 ,经现场试验 ,该方案获得成功 ,并于温峡口水库大坝除险加固工程中付诸实施
Wenxiakou Reservoir is one of the first batch of key risk reservoirs in China. There is a serious problem of seepage and destroying of the dam. Many direct grouting tests have not been successful and many engineering schemes have been compared over the years. Because most of the economy Or technical difficulties have not been put into practice. It is proposed that high-pressure jet grouting should be used to construct a continuous high-spray wall with a certain height to cut off the leakage of the surface cracks and strong weathered layers of the bedrock and form the grouting cover plate, and then apply the basement impervious curtain grouting. Success, and in Wen Xiakou dam reinforcement project put into practice
