CONSTRUCTION METHOD OF GROUND IMPROVEMENT BODY
To provide a construction method of a ground improvement body allowing decrease of discharge pressure to be prevented or suppressed when constructing a ground improvement body directly under the bottom of an existing building.SOLUTION: A construction method of a ground body 100 is provided with: a prior process for constructing an upper improvement body 110 from a specific depth T1 to a bottom part 34 by injecting in a horizontal direction solidification material K1 including a solidification component while a rod 20 inserted in the ground G from a bottom part 34 of an underground body 32 of an existing building 30 is moved and rotated in a vertical direction; and a post process for constructing a lower improvement body 120 from a designed improvement depth T2 to the upper improvement body 110 by injecting in the horizontal direction solidification material K2 while moving and rotating the rod 20 in the vertical direction after specific hours from the prior process elapse.SELECTED DRAWING: Figure 1
【課題】既存建物の底部の直下に地盤改良体を造成する際の排泥の排出圧力の低下を抑制又は防止する。【解決手段】地盤改良体１００の造成工法は、既存建物３０の地下躯体３２の底部３４から地盤Ｇに貫入したロッド２０を上下方向に移動させ且つ回転させながら固化成分を含む固化材Ｋ１を横方向に噴射し所定深度Ｔ１から底部３４まで上部改良体１１０を造成する先工程と、先工程から所定時間後にロッド２０を上下方向に移動させ且つ回転させながら固化材Ｋ２を横方向に噴射し設計改良深度Ｔ２から上部改良体１１０まで下部改良体１２０を造成する後工程と、を備えている。【選択図】図１
