Then, the pump body gradually discharges the seawater in the suction bucket foundation 4, so that negative pressure is formed in the suction bucket foundation 4, and the seawater presses the suction bucket foundation 4 into the soil. In a similar way, the seawater below the tank bottom 6 can be gradually discharged through the pump body, so that more auxiliary downward pressure is provided for the suction bucket foundation 4. After the suction bucket foundation 4 is sunk into the soil, in order to realize the cyclic utilization of the upper support and the lower support, the upper support can be separated from the supporting structure, the lower hoop 8 is separated from the supporting structure, the bottom 6 of the lower buoyancy tank 5 is moved downwards and pressed down to the seabed by injecting water into the lower buoyancy tank 5 and the like, the lower buoyancy tank 5 is separated from the seabed under the action of reaction force, the lower buoyancy tank 5 is floated upwards by injecting gas into the lower buoyancy tank 5 and the like, and the upper support and the lower support are dragged to a specified position by the tug boat.

When liquid is introduced into the lower buoyancy tank 5 through the first through hole 10, the tank bottom 6 can move downwards, and the lower buoyancy tank 5 is separated from the seabed under the action of a reaction force; similarly, the lower buoyancy tank 5 can be separated from the seabed when gas or liquid is introduced through the second through hole 9 to the bottom 6 of the tank. The lower buoyancy tank 5 is preferably provided with a limiting structure for limiting the limit position of the downward movement of the tank bottom 6 and preventing the tank bottom 6 from being separated from the lower buoyancy tank 5.

When the floating transportation operation is carried out, the upper bracket supports the supporting structure through a sling 17; when sinking, the sling 17 retracting device releases the sling 17 and the support structure sinks gradually. Because the sling 17 is multiple, when the supporting structure inclines, the declined side is under the pulling force of the sling 17, thereby having the function of righting. When the upper bracket is recovered, the upper hoop 13 is separated from the jacket 16, and the sling 17 is separated from the suction bucket foundation 4; the lower hoop 8 should be disengaged from the jacket 16 when the lower cradle is retracted.
For another example, when the supporting structure includes a tower 3, a jacket 16 and a plurality of suction bucket foundations 4, the upper end of the jacket 16 is fixedly connected to the tower 3, and the lower end of the jacket 16 is fixedly connected to the plurality of suction bucket foundations 4, the upper hoop 13 may be further sleeved outside the tower 3, the upper cross-link 12 is a gantry-type cross-link, the inner surface of the upper hoop 13 is used for limiting contact with the tower 3, and the lower hoop 8 can tightly hold the tower 3 (as shown in fig. 11).
When the upper hoop 13 tightly holds the tower drum 3, the upper support can support the tower drum 3 and can be used for improving the stability of the floating operation process; when a certain gap is loosened between the upper hoop 13 and the tower drum 3, the upper hoop 13 and the tower drum 3 can move relatively in the vertical direction, and the tower drum 3 can be righted in the sinking operation process. When the lower hoop 8 holds the jacket 16 tightly, floating and sinking operations can be performed. When the upper hoop 13 is separated from the tower 3 and the lower hoop 8 is separated from the jacket 16, the upper support and the lower support can be recovered.
