Title:
CONSTRUCTION METHOD OF UNDERGROUND BASE-ISOLATION WALL
Document Type and Number:
Japanese Patent JP2016204959
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a construction method of an underground base-isolation wall capable of constructing in an original position the underground base-isolation wall provided by filling an underground hole of a column row shape with a clay-based material having water absorptive expandability.SOLUTION: A method for constructing a continuous wall-shaped underground base-isolation wall by filling an underground hole 12 of a column row shape excavated-formed in the ground with a clay-based material having water absorptive expandability, constructs the underground base-isolation wall by repeating a process of discharging excavation soil 20 on the ground by excavating-forming the underground hole 12 by an auger 10 and a process of substituting-filling one underground hole 12 with-by the clay-based material having the water absorptive expandability by injecting-filling slurry S of predetermined density composed of the clay-based material having the water absorptive expandability into a space of the underground hole 12 from the tip of the auger 10 by sending to the tip of the auger 10 via a hollow pipe 18 installed in the auger central axis, on the respective underground holes 12 formed in the column row shape.SELECTED DRAWING: Figure 1-3
