The upper end of the main frame 1 is provided with a plurality of basket bolts 4 in a circular array around the axis of the sleeve hole 3, one end of the basket bolt 4 is rotatably connected to the main frame 1, and the other end of the basket bolt 4 is provided with a connector connected to the outer circumferential surface of the upper end of the movable sleeve 2, and one end of the basket bolt 4 points to the center of the sleeve hole 3.

[0025] In this embodiment, during construction, the following steps are followed:

[0026] Construction preparation: According to the sea conditions and actual conditions of the site, large floating cranes and transport barges are selected to ensure smooth progress of foundation construction. In addition to the pile driver, pile hammers, pile turners, and pile delivery devices are also required. Before construction, it is necessary to confirm that the foundation steel structure has been completed and accepted, and transported to the construction site by a transport ship; the tooling and lifting equipment required for lifting have been prepared and inspected to be intact.

[0027] The main frame, movable sleeves and other piling tools are then transported to the project site by transport barge.

[0028] After that, a large floating crane is used to enter the site for positioning, and the main frame is lowered to the mud surface according to the machine position coordinates. The commander adjusts the position of the ship and the crane according to the data displayed by the positioning software to put the positioning pile stabilization platform in place to the specified position (position deviation ±0.25m; direction deviation ±3°). The specific requirements are determined according to the project design requirements. After it is in place, the positioning software is used to record the center point position and orientation of the positioning pile stabilization platform.

[0029] Then use a floating crane to lift the movable sleeve to the first sleeve hole. Preliminary adjust the verticality of the movable sleeve by adjusting the top basket bolt.

[0030] The floating crane lifts the pile to the top of the movable sleeve and slowly lowers it until the pile bottom passes through all the sleeves and falls into the mud surface. The initial verticality of the pile is measured by the total station. The movable sleeve is adjusted again by adjusting the top basket bolt to adjust the verticality of the steel pipe pile.

[0031] The pile driver and pile hammer are hoisted to drive the steel piles to the designed elevation. The verticality of the steel piles is monitored in real time by the total station during the process. After the pile driving is completed and accepted, the movable sleeve is lifted to the next sleeve mouth by floating crane, and the above steps are repeated for piling operation. After all the piling is completed, the main frame and the movable sleeve are hoisted to the next position for piling operation. After this setting, there is no need to adjust the verticality of the main frame 1, and only the verticality of the movable sleeve 2 can be adjusted by the basket bolt 4.

[0032] As a preferred mode, an ear plate 5 connected to the connector is provided on the outer circumferential surface of the upper end of the movable sleeve 2. By providing the ear plate 5 to be connected to the connector, the connection between the top end of the movable sleeve 2 and the turnbuckle 4 is achieved.

[0033] As a preferred embodiment, an open guide tube 6 is coaxially provided at the upper end of the movable sleeve 2 , and the inner diameter of the end of the guide tube 6 facing away from the movable sleeve 2 is larger than the inner diameter of the end facing the movable sleeve 2 .

[0034] As a preferred mode, the aperture adjustment limit plate includes a plurality of plate units 7, and a plurality of plate units 7 are evenly arranged around the lower end of each sleeve hole 3, and the distance between the upper end of the plate unit 7 and the axis of the sleeve hole 3 is greater than the distance between the lower end of the plate unit 7 and the axis of the sleeve hole 3, and the plate unit 7 is elastic. The bottom end of the movable sleeve 2 is limited by a plurality of plate units 7, so that in the process of adjusting the top end of the movable sleeve 2 by using the basket bolt 4, the bottom end of the movable sleeve 2 will not be displaced laterally; because the plate unit 7 is elastic, the outer diameter of the bottom end of the movable sleeve 2 is not affected by being larger or smaller, and secondly, in the process of adjusting the top end of the movable sleeve 2 by using the basket bolt 4, the bottom end of the movable sleeve 2 will rotate to a certain extent, and the elastic setting will not limit the bottom end of the movable sleeve 2 from rotating to a certain extent.

[0035] As a preferred method, a monitoring device is provided on the main frame 1 corresponding to each sleeve hole 3, and the upper and lower ends of the sleeve hole 3 are within the sight range of the monitoring device. The floating crane lifts the pile to the guide pipe 6 on the top of the movable sleeve 2 and slowly lowers it. During the process, the lowering of the pile is monitored by an underwater camera until the bottom of the pile passes through all the movable sleeves 2 and falls into the mud surface.

[0036] As a preferred method, Figure 5 , Figure 6 As shown, the monitoring device includes a camera 8, a trolley 9, a track 10, a winch 11, a wire rope 12, and a support 13. The main frame 1 is provided with a track 10 parallel to the axis of the sleeve hole 3 through the support 13. The upper end of the track 10 reaches the upper surface of the main frame 1, and the lower end of the track 10 reaches the lower surface of the main frame 1. The trolley 9 is rolled on the track 10. The camera 8 is arranged on the trolley 9, and the line of sight of the camera 8 is toward the axis of the corresponding sleeve hole 3. The winch 11 is arranged on the upper surface of the main frame 1, and the winch 11 is connected to the trolley 9 through a wire rope 12.

[0037] During the process of lowering the pile driven by the floating crane to the guide tube 6 at the top of the movable sleeve 2, the camera 8 is moved by lowering the winch 11 and the wire rope 12 to monitor the bottom position of the movable sleeve 2 in real time. Until the bottom of the movable sleeve 2 enters the area surrounded by the corresponding plate unit 7. The trolley 9 moves up and down through the track 10.

[0038] As a preferred embodiment, an anti-sinking plate 14 is provided at the bottom of the main frame 1, and a center hole 15 is opened in the center of the anti-sinking plate 14. The anti-sinking plate 14 is used to ensure that the main frame 1 can fall on the mud surface without sinking, and the center hole 15 opened in the center of the anti-sinking plate 14 prevents mud and sand from remaining on the anti-sinking plate 14 to increase the lifting weight.
