SLOPED GROUND IMPROVEMENT CONSTRUCTION MACHINE AND SLOPED GROUND IMPROVEMENT METHOD USING THE SAME
To provide: a sloped ground improvement construction machine capable of performing a preferable construction work, while keeping an aimed slope angle when improving ground by sloping at a prescribed angle, and capable of realizing a sloped improved body of a high quality; and a sloped ground improvement method using the same.SOLUTION: A ground improvement construction machine 1 comprises: a leader 4 inclinable at any angle; a rod 5 rotated by a rotation driving part 6 elevating along the leader 4; a rotation shaft 7 connected to a lower part of the rod 5; and an agitation blade 8, an excavation blade 9 and a tip end penetrating member 10 provided on the rotation shaft 7. The ground improvement construction machine can prepare an inclined improvement body 20 inclined with respect to the vertical direction. When the rotation shaft 7 is caused to penetrate into the ground in an attitude inclined at a prescribed angle, a tip end of the tip end penetrating member 10 is projected so as to reach a deepest layer S of the improved ground always before the agitation blade 8 and the excavation blade 9 reach there.SELECTED DRAWING: Figure 1
【課題】所定の角度に傾斜させて地盤を改良するにあたり、狙った傾斜角度を維持しつつ良好な施工を行うことができ、高品質の斜め改良体を実現することができる、斜め地盤改良施工機および同施工機を用いた斜め地盤改良工法を提供する。【解決手段】任意の角度に傾斜可能なリーダー４と、前記リーダー４に沿って昇降する回転駆動部６で回転させるロッド５と、前記ロッド５の下部に連結された回転軸７と、前記回転軸７に設けられた撹拌翼８と掘削翼９と先端貫入部材１０とを備え、鉛直方向に対して傾斜した斜め改良体２０を造成することが可能な地盤改良施工機１であって、前記回転軸７を所定の角度に傾斜させた姿勢で地盤に貫入させるにあたり、前記先端貫入部材１０の先端が、前記撹拌翼８および前記掘削翼９よりも常に先行して改良地盤の最深層Ｓに到達するように突き出した構成である。【選択図】図１
