GROUND IMPROVEMENT DEVICE, GROUND IMPROVEMENT SYSTEM, AND GROUND IMPROVEMENT METHOD
To provide a ground improvement device, and a ground improvement method capable of improving a water bottom ground without requiring a press-in configuration toward the water bottom ground and a stir configuration stirring the water bottom ground.SOLUTION: A ground improvement device 1 is suspended in water with a wire 22 connected on its upper surface, penetrating in a soft weak layer 51 by its own weight after touching a surface of the soft weak layer 51. An operator instructs a lifting device to lift up the ground improvement device 1 when recognizing that the ground improving device 1 has descended to a determined distance from the touched surface of the soft weak layer 51. The lifting device lifts the ground improving device 1 by winding up the wire 22. A space S is created along a track below the ground improvement device 1 to be lifted. A supply device supplies a ground improvement material to the ground improvement device 1 through a hose 32 at a supplying speed in accordance with a lifting-up speed of the ground improvement device 1. The ground improvement material is discharged downward from a discharge port 11, the space S being filled with the ground improvement material.SELECTED DRAWING: Figure 3
【課題】水底地盤に向けて押し込む構成及び水底地盤を撹拌する構成を必要とせずに、水底地盤を改良する地盤改良装置、及び地盤改良方法を提供する。【解決手段】地盤改良装置１は、上面に接続されたワイヤ２２で水中に吊り下げられ、軟弱層５１の表面に着底した後も、自重により軟弱層５１に貫入する。操作者は、地盤改良装置１が軟弱層５１に着底してから決められた距離にわたって下降したことを認識すると、昇降装置に対し、地盤改良装置１を引き上げるよう指示する。昇降装置はワイヤ２２を巻き上げて地盤改良装置１を引き上げる。引き上げられる地盤改良装置１の下方には、その軌跡に沿って空間Ｓが生じる。供給装置は、ホース３２を経由して、地盤改良装置１の引き上げ速度に応じた供給速度で、地盤改良材を地盤改良装置１に供給する。この地盤改良材は、吐出口１１から下向きに吐出され、この地盤改良材によって空間Ｓが充填される。【選択図】図３
