摘要

PROBLEM TO BE SOLVED: To provide a foundation pillar structure in a weak ground capable of effectively increasing the horizontal resistance and vertical supporting force of a pillar while minimizing the increase in costs.;SOLUTION: A pillar hole 1 having a large diameter part is excavated near a pillar head 21, an existing pillar 2 is built in the pillar hole 1, and a charged solidifying material 3 is filled in the pillar hole 1 and the large diameter part 11. A frame body 4 having a cover body 41 is buried in the large diameter part 11 so that the existing pillar 2 can be inserted in the charged solidifying material, and the cover body 41 of the frame body 4 and the pillar head 21 of the existing pillar 2 are disposed in proximity to each other.;COPYRIGHT: (C)2004,JPO
