混凝土防渗墙是在松散透水地基中连续造孔,以泥浆固壁,往孔内灌注混凝土而建成的墙形防渗建筑物。其施工简便,速度快,消耗少,防渗效果好,成为我国水利水电工程覆盖层防渗处理的首选方案。文章通过某水库除险加固工程的坝基防渗就是采用混凝土防渗墙技术的工程实例,全面了解防渗墙施工的各个工序及主要施工方法,从而为掌握这项技术积累了实践经验。 Concrete impervious wall is a wall-shaped impervious building constructed by continuous hole making in loosely permeable foundation, solidifying the wall with mud and pouring concrete into the hole. Its construction is simple, fast, less consumption, anti-seepage effect is good, become China’s water conservancy and hydropower projects cover the preferred solution to seepage control. This article through a reservoir reinforcement project dam foundation seepage is the use of concrete cutoff wall technology engineering example, a comprehensive understanding of the impermeable wall construction of the various processes and the main construction methods, so as to master the technology has accumulated practical experience.
