[0037] S7. Continue the construction of underwater bored piles.

[0038] During construction, explosives are loaded into the guide sleeve 5 and pressed by the pressure rod 7, so that the impact force generated by the explosion of the explosives acts on the isolated rocks to break the isolated rocks, thereby facilitating the completion of the established construction plan, improving construction efficiency and ensuring construction quality.

[0039] Specifically, refer to Figures 2 to 5 The fixing tooling includes a fixing plate 1, a driving assembly 2 and a clamping rod 3. The fixing plate 1 is fixedly connected to the water platform 4. There are multiple clamping rods 3, which slide on the fixing plate 1 along the radial direction of the guide sleeve 5. The driving assembly 2 is arranged on the fixing plate 1. The driving assembly 2 has multiple active ends to drive multiple clamping rods 3 to move synchronously toward the guide sleeve 5. The fixing plate 1 can be a whole piece or multiple fixed plates 1 arranged in an array along the circumference of the guide sleeve 5. In this embodiment, there are four fixing plates 1.

[0040] A rubber block 11 is provided between the fixing plate 1 and the above-water platform 4. The rubber block 11 is convenient for absorbing the vibration generated by the guide sleeve 5 and reducing the vibration transmission to the above-water platform 4.

[0041] More specifically, the driving assembly 2 includes a gear ring 21 and a gear 22. The gear ring 21 is rotatably connected to the fixed plate 1. The number of gears 22 is the same as the number of clamping rods 3. The clamping rods 3 are provided with racks 31. Each gear 22 is meshed with the corresponding rack 31. The gear 22 is rotatably connected to the fixed plate 1 and meshes with the inner ring of the gear ring 21. Rotating the gear ring 21 can simultaneously drive multiple clamping rods 3 to move, realize synchronous locking and loosening of the guide sleeve, improve construction efficiency, and ensure the position accuracy of the guide sleeve through self-centering. The gear ring 21 can be driven by a handle 211 threadedly connected to the gear ring 21.

[0042] The fixing plate 1 is fixedly connected with a locking plate 23, and a locking bolt 24 is threadedly connected with the locking plate 23, and the head of the locking bolt 24 is tightly pressed against the top surface of the gear ring 21.

[0043] In addition, a buffer hole 41 is provided on the water platform 4 for the guide sleeve 5 to pass through, and a spring buffer is connected to the side wall of the guide sleeve 5 in the horizontal direction. The spring buffer includes a buffer rod 51 and a compression spring 52. One end of the buffer rod 51 is inserted into the guide sleeve 5, and the other end is connected to the abutment plate 53. The compression spring 52 is sleeved on the buffer rod 51, and one end of the compression spring 52 abuts against the outer wall of the guide sleeve 5, and the other end abuts against the abutment plate 53.
