The underground continuous wall are widly applied in water resources and hydropower engineering around the world, then extended to the construction, municipal, transportation, mines, railways and environmental protection departments. The initial thickness of the underground continuous wall is generally not more than 0.6 m and the depth is not more than 20 m. With the improvement of the technology developed rapidly the underground continuous wall with a thickness of over 1.2 m and a depth beyond 100 m was constantly emerging.
