<P>PROBLEM TO BE SOLVED: To provide a wall-like soil improvement body which is formed by an underground wall structure in soil, has a rectangular shape or the like on the periphery in the plan view, and is formed continuously having a plurality of corners, for hardly causing damages at the corners of an underground wall forming the periphery in the plan view in the wall-like soil improvement body even when a liquefaction phenomenon occurs. <P>SOLUTION: On an inner side in the plan view of a plurality of corners 121, 123 forming key parts on the periphery of an underground wall 110, a corner reinforcing part 131 is formed and provided so that a wall thickness of the underground wall 110 forming the corner is thicker than a wall thickness of the underground wall 110 of the other parts that are not the corner. Thus, since the strength of the corner of the underground wall provided with the corner reinforcing part 131 is increased, damages at the corner are prevented even when the liquefaction phenomenon occurs, and the strength of the entire wall-like soil improvement body is increased. <P>COPYRIGHT: (C)2013,JPO&INPIT |
