WATER BOTTOM GROUND IMPROVEMENT METHOD
To provide a water bottom ground improvement device which enables construction in a short construction period at low cost, and a water bottom ground improvement method using the device.SOLUTION: A casing 32 of a water bottom ground improvement device is abutted against a sea bottom ground and is press-fit to a target depth thereof. The press-fitting causes the water bottom ground to be taken into the casing 32. Then, in a state where the casing 32 is press-fit to the target depth of the sea bottom, an improvement material is sent to a stirring/mixing blade 35 in the casing 32 through a material supply path 25. In a case where the casing 32 is press-fit to the water bottom ground, the stirring/mixing blade 35 is operated so that the water bottom ground taken into the casing 32 and the improvement material are stirred and mixed, and an original ground (water bottom ground taken into the casing 32) is improved upward from the bottom.SELECTED DRAWING: Figure 5
【課題】短工期・低コストでの施工を可能にする水底地盤改良装置と当該装置を用いた水底地盤改良方法を提供する。【解決手段】水底地盤改良装置のケーシング３２を海底地盤に突き当て目標深度まで圧入する。このとき、圧入に伴って水底地盤がケーシング３２内に取り込まれる。次いで、ケーシング３２が海底の目標深度まで圧入された状態で、ケーシング３２内の攪拌混合翼３５に向けて材料供給路２５を介して改良材を送る。そして、ケーシング３２が水底地盤に圧入された状態で、ケーシング３２内に取り込まれた水底地盤と改良材が攪拌混合されるように攪拌混合翼３５を作動させて、原地盤（ケーシング３２内に取り込まれた水底地盤）を下から上に向けて改良する。【選択図】図５
