Title:
SOIL IMPROVEMENT DEVICE AND CONSTRUCTION METHOD OF IMPROVED WALL BODY
Document Type and Number:
Japanese Patent JP2018031248
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a soil improvement device which enhances an excavation force and an excavation speed of an admixture/agitation head supported to a base machine.SOLUTION: A soil improvement device constructs an improved wall body B by inserting an admixture/agitation head 6 attached to a base machine 1 into the ground. An angle formed of a plane center line C1 and a plane center line C2 of a boom 4 is set as an acute angle while maintaining a caterpillar band 2 of the base machine 1 in substantially-parallel with the plane center line C1 of the improved wall body B. When excavating the admixture/agitation head 6 in the plane center line C1 direction, a component force P1 in the plane center line C1 direction based on a force P in an oscillation motion direction of the boom 4 is utilized as excavation vector toward the plane center line C1 direction, and the admixture/agitation head 6 is excavated.SELECTED DRAWING: Figure 5
