“倒挂井法”施工地下连续墙,是水利部门曾在水库枢纽工程中用于施工粘土混凝土防渗墙和粘土防渗墙,深度近60米。此法不需要专门的成槽机械,不需要用泥浆护壁。 “Inverted Hanging Method” for the construction of underground diaphragm walls was used by the water conservancy departments to construct clay concrete impervious walls and clay impervious walls in reservoirs with a depth of nearly 60 meters. This method does not require special slotting machines and does not require mud protection.
