SOIL IMPROVEMENT DEVICE AND SOIL IMPROVEMENT METHOD
To provide a soil improvement device for preventing filling materials from engaging with each other due to their irregular shapes and forming a mass, and dropping and supplying the filling materials into a casing pipe.SOLUTION: The present invention comprises a rod 9 rotated by a rotation drive device 7 and inserted into the ground, a casing pipe 10 that is externally fitted to the rod 9 and inserted into the ground, a crushed stone inlet 41 provided on an outer circumference of the casing pipe 10, a hopper body 56 which is arranged on the ground and has an insertion hole for the casing pipe 10 at the bottom, and agitating means provided in the hopper body 56 for agitating the crushed stone inside. By agitating the crushed stone in the hopper body 56 with the agitating means 71, the crushed stone can be smoothly dropped and supplied into the casing pipe 10 from the crushed stone inlet 41.SELECTED DRAWING: Figure 1
【課題】中詰め材が形状凹凸でかみ合い塊状になることを防止し、中詰め材をケーシングパイプ内に落下供給する地盤改良装置を提供する。【解決手段】回転駆動装置７により回転して地盤内に挿入されるロッド９と、このロッド９に外装され地盤内に挿入されるケーシングパイプ１０とを備え、ケーシングパイプ１０の外周に設けた砕石投入口４１と、地上に配置され底部にケーシングパイプ１０の挿通孔を有するホッパー本体５６と、このホッパー本体５６に設けられ内部の砕石を撹拌する撹拌手段とを備える。撹拌手段７１によりホッパー本体５６内の砕石を撹拌することにより、砕石投入口４１から砕石を円滑にケーシングパイプ１０内に落下供給することができる。【選択図】図１
