Abstract

PURPOSE:To obtain sufficient strength in eroded soil layer by a method in which eroded soil layer is mixed with a hardening agent with stirring to form plural pillars at intervals under the ground, and a hardening agent is injected into the eroded soil layer between the pillars to connect the pillars together. CONSTITUTION:Eroded soil layer is excavated to a given depth by a stirring blade 3 by turning a rod 2, and the blade 3 is expanded horizontally. A hardening agent is radially injected from the tip of the rod 2, and while mixing the excavated soil layer with the hardening agent with stirring, the rod 2 is pulled up to form a columnar pillar 1. Plural columnar pillars 1 are formed at intervals, and then a hardening agent is injected radially into the eroded soil layer between the columnar pillars 1 from the tip of a boring rod 5 to form a hardened body 4.
