根据枣元水库坝基存在3.5m厚的砂卵石层,从而造成库水渗漏严重的特点,经多方论证,确定对砂卵石层采用高压喷射灌浆方案,在坝基砂卵石层内形成一道垂直连续的防渗帷幕。经设计、施工后,取得了良好效果。
According to the existence of 3.5m-thick sand and gravel layer in Zaoyuan reservoir dam foundation, resulting in the serious leakage of the reservoir water. After multi-dimensional verification, it is determined that a high-pressure jet grouting solution is applied to the sand and gravel layer to form a vertically continuous Anti-seepage curtain. The design, construction, and achieved good results.
