Dead water manner null of wall type subterranean continual wall

摘要

PURPOSE: To positively perform injection of water stopping material with a high accuracy. ;CONSTITUTION: Holes are drilled continuously on the back side or both sides of a place at which a wall type underground continuous wall 1 is to be constructed, and the holes are filled with a solidifying material, or the field soil and the solidifying material are mixed and kneaded. After an injection pipe 2 for water stopping material is assembled in the hole on the back face of the place where a wall type underground continuous wall is to be constructed before the solidifying material is solidified, and column type underground continuous walls 3 are constructed, a wall type underground continuous wall 2 is constructed between the column type underground continuous walls 3. When water leaks from the wall type underground continuous wall 2, water stopping material is injected to the back face of the wall type underground continuous wall 4 through the injection pipe 2.;COPYRIGHT: (C)1996,JPO
