(二)自凝泥浆墙由于自凝泥浆不仅在挖槽时可用作护壁泥浆,而且在槽内凝固后具有一定的强度和良好的防渗性能,因而从七十年代开始在法国、墨西哥等国家用作防渗墙墙体材料。墨西哥从1970年到1977年使用自凝泥浆所修建的防渗墙达6万米~2左右。用自凝泥浆修建防渗墙,不仅可省去大量混凝 (ii) Self-consolidating mud wall Since the self-concreting mud can be used not only as a wall protection slurry during trenching, but also has a certain strength and good impermeability after solidification in the tank, it began in the 1970s in France, Mexico, etc. The country is used as a wall material for impervious walls. In Mexico, from 1970 to 1977, the impervious wall built with self-curing mud reached about 60,000 m2. Using self-concreting mud to build anti-seepage walls can not only save a lot of coagulation
