Title:
GROUND DISPLACEMENT RESTRAINT
Document Type and Number:
Japanese Patent JP3689481
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To fix ground displacement on the rear side of a wall body by supplying the inside of a flexible bag body installed into a ditch with a fluid and deforming the bag body while following up to the displacement of the wall body.
SOLUTION: A continuous wall body 1 in required length is mounted into the ground E, and a ditch 4 in approximately the same depth as the wall body 1 is excavated in parallel with the wall body 1 between the wall body 1 and a building 3. A flexible bag body 5 such as a vinyl bag is set up into the ditch 4, and the bag body 5 is filled with a fluid having specified specific gravity. When the filled fluid is precipitable, a circulating pipe 6 is inserted, and the fluid having specified specific gravity is supplied in a circulating manner from the lower end of the pipe 6 and precipitation is prevented. Such a ground displacement restraint is installed, soil on the front side of the wall body 1 is excavated and removed, and the wall body 1 is supported by a horizontal supporter 2. Fluid pressure in the bag body 5 is adjusted by the specific gravity of the fluid and the height of a fluid surface, and kept at initial water pressure or more in the ground before excavation.
