高喷防渗墙是以高压水泥浆液或高压水流强力冲击切割地层,使水泥浆液与地基土粒掺混,形成充填凝结体并彼此连接而形成的防渗墙体。当今防渗墙的应用范围较为广泛,其中存在用于长江永安堤防护加固工程中,作用为防渗功能的高喷法防渗墙。
High-pressure jet cutoff wall is a high-pressure cement slurry or high-pressure water jet cutting force strong impact, so that cement slurry mixed with the foundation soil, the formation of filled with condensate and connected to each other to form impervious wall. Nowadays, the application scope of impermeable wall is relatively wide, in which there is a high-jet method impermeable wall which is used for the protection and reinforcement project of the Yongan dyke in the Yangtze River.
