SOIL IMPROVEMENT BODY CONSTRUCTION METHOD, SOIL IMPROVEMENT DEVICE, SOIL IMPROVEMENT BATHOLITH
PROBLEM TO BE SOLVED: To form a soil improvement body over a wide range in a lateral direction by chemical grouting in one place while keeping a chemical grouting amount small.SOLUTION: A main chemical solution EA reacting with water to gelate is penetration-injected in a laterally-prevailing manner into object ground 12 by injection pressure that does not cause cleavage of the object ground 12. Thus, a soil improvement body 50 assuming a flat shape longer in a lateral direction than in a vertical direction is formed in the object ground 12.SELECTED DRAWING: Figure 2
【課題】薬液の注入量を抑えつつ、一箇所の薬液注入で横方向に対して広範囲に地盤改良体を形成する。【解決手段】水と反応してゲル化する主薬液ＥＡを対象地盤１２が割裂しない注入圧力で対象地盤１２に横方向に卓越させて浸透注入させることで、対象地盤１２に上下方向よりも横方向が長い扁平形状の地盤改良体５０を形成する。【選択図】図２
