GROUND IMPROVEMENT METHOD, GROUND IMPROVEMENT DEVICE, AND IMPROVED BODY
To produce an improved body in the ground that is stronger than a columnar improved body produced at the same improvement rate without the need for mixing with the in-situ ground material.SOLUTION: A construction device included in a ground improvement device comprises, for example, a computer that controls the construction device and other configurations of a ground improvement device 9 based on information on the construction of the ground improvement work. The computer acquires penetration depth information indicating the depth at which a steel pipe penetrates into the ground from a storage unit, and based on this, penetrates the steel pipe. Further, the computer acquires the drawing speed information of the pulling speed of the steel pipe and the discharging speed information of the speed of discharging the solidifying material from the storage unit, and controls pulling means and discharging means based on these. As a result, the ground improvement device pulls out the steel pipe and supplies the solidifying material into a supply pipe. Then, a tubular space occupied by the steel pipe in the ground is filled with the solidifying material supplied from the discharge means through the supply pipe.SELECTED DRAWING: Figure 4
【課題】原位置の地盤材料との混合を必要とせず、同じ改良率で生成された柱状の改良体に比べて強度のある改良体を地盤中に生成させる。【解決手段】地盤改良装置が有する施工装置は、例えば、地盤改良工事の施工に関する情報に基づいて施工装置、及び地盤改良装置９の他の構成等を制御するコンピュータを有する。このコンピュータは、記憶部から、鋼管を地盤に貫入させる深さを示す貫入深さ情報を取得し、これに基づいて、鋼管を貫入させる。また、コンピュータは、記憶部から、鋼管を引抜く速度の引抜速度情報と、固化材を吐出する速度の吐出速度情報と、を取得し、これらに基づいて、引抜手段及び吐出手段を制御する。これにより、地盤改良装置は、鋼管を引抜くとともに、供給管の中に固化材を供給する。そして、鋼管が地盤の中に占めていた筒状の空間には、吐出手段から供給管を通じて供給された固化材が充填される。【選択図】図４
