GROUND IMPROVEMENT METHOD BY CHEMICAL INJECTION AND ASSEMBLY STRUCTURE OF IMPROVEMENT BODIES
PROBLEM TO BE SOLVED: To provide a ground improvement method by chemical injection and an assembly structure of improvement bodies that can control uneven settlement on a ground surface or a ground, even when an amount of injected chemical is reduced.SOLUTION: With the ground improvement method by chemical injection, a ground is improved by forming a plurality of roughly spherical improvement bodies by chemical injection, arranged in a series in horizontal and depth directions in the ground. Four improvement bodies 11a, 12a, 13a, 14a are treated as a group, the improvement bodies being installed at a same depth and in contact with or overlapping with each other. The plurality of improvement bodies is formed in the ground, such that when seen from above, at least one improvement body 15a of four improvement bodies of another group is located at a spot corresponding to a not-yet-improved part 10 at a center of the group of the improvement bodies 11a, 12a, 13a, 14a that is adjacent to the other group in a depth direction.SELECTED DRAWING: Figure 1
【課題】薬液注入工法において薬液注入量を低減しても、地表面や地盤における不等沈下を抑制可能である薬液注入による地盤改良工法および改良体集合構造を提供する。【解決手段】この薬液注入による地盤改良工法は、薬液注入により略球状の改良体を地盤内の深さ方向および水平方向に多数形成することで地盤を改良する際に、同一深さに配置されるとともに相互に接するかまたは一部重なり合うように配置された４つの改良体１１ａ，１２ａ，１３ａ，１４ａを一組として上面から見たとき、その中央に存在する未改良部分１０に対し、深さ方向に隣接する別の一組の４つの改良体の内の少なくとも１つの改良体１５ａが位置するようにして多数の改良体を地盤内に形成する。【選択図】図１
