GROUND IMPROVEMENT BODY AND GROUND IMPROVEMENT METHOD
PROBLEM TO BE SOLVED: To provide a ground improvement body and ground improvement method in which a ground improvement range can be freely set.SOLUTION: After constructing a water barrier wall 50 enclosing a predetermined area in a ground G, a water injection well 52 and a pumping well 54 are constructed in the ground G inside the water barrier wall 50. Subsequently, a supercooled solution is injected into the ground G, the supercooled solution is solidified by feeding a crystallization agent 32 into the ground G in which the supercooled solution has penetrated to solidify the ground G inside the water barrier wall 50. The improved ground G2 is formed by the supercooled solution which is solidified in the ground G enclosed by the water barrier wall 50.SELECTED DRAWING: Figure 4
【課題】地盤改良範囲を自由に設定できる地盤改良体及び地盤改良方法を提供する。【解決手段】所定の面積を取り囲む遮水壁５０を地盤Ｇに構築し、遮水壁５０の内側の地盤Ｇに注水井戸５２と揚水井戸５４を構築する。さらに、地盤Ｇへ過冷却溶液を注入し、前記過冷却溶液が浸透した地盤Ｇに結晶剤３２を投入して過冷却溶液を固化させて遮水壁５０の内側の地盤Ｇを硬化させる。改良地盤Ｇ２は、過冷却溶液が遮水壁５０で囲まれた地盤Ｇ中で固化して形成されている。【選択図】図４
