The centers of the upper sleeve 82 and the lower sleeve 83 are the center holes corresponding to the pile diameters. The center holes of the upper sleeve 82 and the lower sleeve 83 are arranged corresponding to the different height positions of the pile.

[0037] The second replaceable modules 40 adjacent in the height direction are sequentially connected through the flange structures to form the frame structures with corresponding heights.

[0038] The upper platform module 10, the first replaceable modules 20, the sleeve module 30, the second replaceable modules 40, and the anti-sinking module 50 are arranged in sequence in the height direction and are fixedly connected by the flange structures to form a vertical frame mechanism. The vertical frame mechanism is provided with guide holes corresponding to the positions of each set of connected flange structures. The auxiliary piles 60 are respectively inserted into the vertically connected guide holes at the same position from top to bottom to form a multi-pile piling frame center frame. The upper platform module 10 is provided with guide holes at the positions of four corners for placing the auxiliary piles 60;

[0039] The inner end of the pile 100 abuts against the radial stop end of the top limiting mechanism 72 after assembly and is arranged from top to bottom. The pile penetrates through the corresponding center holes of the upper sleeve 82 and the lower sleeve 83 to perform downward piling work.

[0040] In specific implementation, each top limiting mechanism 72 includes two side connecting edges 73, an arc-shaped baffle 74, and two side struts 75. The arc-shaped baffle 74 is the radial stop end. The arc-shaped baffle 74 is arranged between the two side connecting edges 73.

[0045] In the embodiment, the anti-sinking module 50 is mainly provided with an anti-sinking plate at the bottom, so as to facilitate the placement of the structure on the seabed during construction.

[0046] The first replaceable module 20 and the second replaceable module 40 are used to adjust the elevation of each component. The second replaceable module 40 is used to adjust the elevation of the top of the sleeve module, which is determined by the elevation of the top of the pile to be driven. Generally, the elevation of the sleeve 82 should be less than the elevation of the top of the pile to be driven. The first replaceable module 40 is used to adjust the elevation of the upper platform module 10, which is determined by the water depth of the construction area.

[0047] In the first embodiment, the box girder structure 11 is provided with a ring assembly 70 at the four corners, and the sleeve module 80 is provided at the four corners of the center frame structure, so that the pile is arranged at the position extending outward from the four corners of the center frame of the pile driver.

[0048] In the second embodiment, the box girder structure 11 is provided with a ring assembly 70 at the center of each side, and the sleeve module 80 is provided at the center of each side of the center frame structure, so that the pile is arranged at the position extending outward from the center of each side of the center frame of the pile driver, without the second replaceable module 40.

[0049] In the embodiment, the following steps are included:

[0050] S1. The first replaceable module 20 and the second replaceable module 40 are reasonably arranged according to the water depth and the elevation of the top of the pile. The second embodiment is suitable for the construction of piles with large water depth and small elevation.

[0051] S2. The position of the sleeve module is reasonably arranged. The structure of the first embodiment can adapt to a larger root opening and use less material, which can save costs. The advantage of the second embodiment is that the adjustable root opening range is not limited by the interference of the auxiliary pile, so it has a larger root opening range, and is far away from the auxiliary pile, which can reduce the influence of the auxiliary pile on the pile to be driven. The second embodiment is suitable for the construction of piles with large water depth and small elevation.

[0052] S3. The position of the sub-sleeve and the top limiting device is adjusted according to the actual root opening.

[0053] S4. The pile driver is placed on the seabed by the crane.

[0054] S5. Four auxiliary piles are hoisted into the pile driver guide pipe frame and connected to the upper platform module through the leveling mechanism.

[0055] S6. The pile driver is leveled.

[0056] S7. The pile to be driven is hoisted.

[0057] S8. The pile is driven into the sluice gate. The pile is straightened by the top limiting device so that it is located in the center of the limiting. At the same time, two theodolites and one level are set on the side to observe its verticality and elevation.

[0058] S9. When the deviation caused by the verticality of the pile is less than the lateral distance of the upper sleeve flare, lower it slowly while continuing to observe its verticality until it can pass through the center hole of the upper and lower sleeves.

[0059] S10. Continue lowering the pile until it sinks into the mud.

[0060] S11, hammer, pile driving.

[0061] Its working principle is as follows: The inner end of the pile is tightly attached to the radial stop end of the top limiting mechanism and arranged from top to bottom. The pile passes through the corresponding center holes of the upper and lower sleeves for downward pile driving. Each set of top limiting mechanisms is adjusted and arranged along the opening direction of the clamping ring, so that the root opening size of the pile can be adjusted and set according to actual needs. In addition, the fixed positions of the upper and lower sleeves corresponding to the mother sleeve are matched and installed according to the radial position of the top limiting mechanism assembled on the clamping ring, ensuring the root opening size of the lower part of the pile. Since the center hole size of the upper and lower sleeves is selected according to the pile diameter, the diameter of the built-in sub-sleeve can be changed to adapt to the driving of piles of different sizes. Furthermore, the modular design allows for the selection of a corresponding number of first and second replaceable modules to adapt to different water depths and pile top elevations. This makes the root opening and sleeve diameter of the pile driving frame adjustable, resulting in good equipment versatility and reduced equipment costs.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
