PROBLEM TO BE SOLVED: To provide an existent construction ground improvement structure firstly in which damage with local bending distortion of a base structure can be suppressed by improving or recovering bearing power of a bearing ground in a settlement non-correction location and further, to provide an existent construction ground improvement structure secondly in which work efficiency can be improved by simplifying backfill work of a settlement correction member.SOLUTION: When flowable improvement soil is hardened within a working recessed spot 2, a bearing ground recovery body 4 is formed within the working recessed spot 2, and a plurality of settlement correction members 3 and a reinforcement arrangement member 11 are included and restricted within the bearing ground recovery body 4. Then, a base structure 51 is point-supported at a plurality of positions P by the plurality of settlement correction members 3, such that uneven settlement is corrected, and a down face of the base structure 51 is face-supported by the bearing ground recovery body 4 along a planar arrangement of foundation rising parts 51a. |
