量の水平変位が生じる。 In general, a ground improvement machine consists of a turret 2 fixed on a ship's hull 1 by a winch wire 9, as shown in Fig. 1.
The guide clamp 7 or leader 8 of the soil improvement machine is used as a guide to slide up and down as the winch wire 9 winds in and unwinds, and is raised and lowered in the vertical direction. The soil improvement machine has an improvement machine drive section 4 at the top and a vertically elongated main body steel pipe 5 at the bottom.The sliding part with the turret 2 is the guide clamp 7 part at the top of the soil improvement machine, and the guide clamp 7 and the leader 8
There is usually a gap of 20mm or more between them. Therefore, the ground improvement machine and the turret have different inclinations due to large differences in the external forces applied to them, such as wind waves, tides, and resistance to ground penetration of the main steel pipe, so a considerable amount of horizontal displacement occurs between the improvement machine and the hull. .
