水泥土搅拌桩截渗墙施工技术工法简便,成墙速度快,防渗效果好,成本低廉,对地质条件要求比较严格,适用于地质条件变化不大,深度不宜过深的截渗墙施工。高压喷射灌浆截渗墙适合于任何地层,施工深度一般不受限制,成本较高,成墙速度比较慢。水泥土搅拌桩截渗墙与高压喷射灌浆截渗墙结合新技术,可以彼此弥补其缺陷,该技术在山东东平湖围坝除险加固工程中首次应用,经检测防渗效果良好,可在黄河堤防防渗工程中推广应用。
The construction technique of cement-soil mixing pile cutoff wall is simple and convenient, the wall formation speed is fast, the seepage prevention effect is good, the cost is low, and the requirements on the geological conditions are relatively strict, and is suitable for the construction of the cutoff wall whose geological conditions are not changed much and the depth is not too deep. High-pressure jet grouting cutoff wall is suitable for any formation, the construction depth is generally not limited, the cost is higher and the wall speed is slower. Cement-soil mixing pile cutoff wall and high-pressure jet grouting cutoff wall combined with new technologies can make up for each other’s shortcomings. This technology was first applied in the reinforcement project of Dongping Lake dam in Shandong province. The tested anti-seepage effect is good, Application of embankment seepage control project.
