SOIL IMPROVEMENT BODY, SOIL IMPROVEMENT STRUCTURE, AND FOUNDATION CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a soil improvement body capable of inexpensively suppressing ground deformation effectively against a force from the outside, a soil improvement structure, and a foundation construction method using the soil improvement body.SOLUTION: A soil improvement material is mixed into excavated ground and agitated; a first wall body 21 elongated in one direction in a plan view is provided; and a second wall body 22 connected to an outer hull of the first wall body 21 and elongated in a direction of crossing the one direction is provided. Thereby, a soil improvement body 20 is formed. The soil improvement body can also be configured by providing the second wall body 22 in a direction orthogonal to the one direction.
