[0045] From the above, we can know that:

[0046] The present invention addresses the following technical issues: The currently disclosed hammer-driven pipe sinking, vibration-driven pipe sinking, and static pressure-driven pipe sinking all fall within the category of soil-squeezing cast-in-place piles. During the construction of the pipe piles, a prefabricated concrete or steel structure pile tip is installed at the pile head, and the piles are driven into the soil primarily by hammering, driving, and static pressure. The original soil at the pile site is squeezed toward the surrounding soil, inducing a significant surrounding soil squeezing effect, which endangers the safety performance of underground structures within the affected area. The present invention adopts the technical solutions of the above-mentioned embodiments. Furthermore, the implementation process of the above-mentioned technical solutions is as follows:

[0047] The electrical components in this device are all existing technologies, and their models are only one of them. As long as the electrical components can achieve the purpose of this device, they can be used. All electrical components in the device are connected to their adapted power supplies through wires, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working. The detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of electrical control is given.

[0048] Move the device to the designated area, then electrically connect the device to the external power supply, then fix the clamp 23 on the outside of the pipe pile 3, fix the two clamps 23 with screws, then start the first hydraulic cylinder 21, the output end of the first hydraulic cylinder 21 pulls the second vertical plate 22, so that the second vertical plate 22 drives one of the moving rods 17 to move, because the moving rod 17 is rotatably connected to the bent rod 16, the bent rod 16 is rotatably connected to the square plate 15, and the square plate 15 is fixed to the bearing column 14, and the bearing column 14 is rotatably connected to the cylindrical cavity 13, so that the four moving rods 17 can be moved along the inner side of the limiting groove 18 in the direction of approaching each other, and then the four curved plates 19 are moved in the direction of approaching each other, until the curved plate 19 clamps and fixes the L-shaped rod 24, and the pipe pile 3 can be fixed;

[0049] Then, the first motor 4 and the second motor 10 are started. The output end of the first motor 4 drives the screw 6 to rotate, causing the bearing plate 7 to move downward along the inner side of the side groove 5. At the same time, the output end of the second motor 10 drives the drill rod 11 to rotate, causing the blades 28 to rotate to drill the ground. Water is added during drilling, causing the blades 28 to stir the loosened soil and mix it with the water to form mud. The mud sinks due to the gravity of the pipe pile 3 and enters the mud bin formed between the partition plate 25 and the load-bearing steel plate 26 through the diversion hole 29.

[0050] Then the mud pump is started, and the input end of the mud pump sucks the mud in the mud bin out of the interior of the pipe pile 3 through the mud pipe 30, thereby reducing the bottom reaction force and facilitating smooth sinking.

[0051] Through the above configuration, this application can certainly solve the above technical problems and achieve the following technical effects:

[0052] 1. The present invention, through the structural design of the moving mechanism, the fixing mechanism and the drilling mechanism, enables the device to basically eliminate the soil squeezing effect of precast pile construction, widely improve the scope of use and construction difficulty of precast piles, speed up work efficiency and enhance the safety of the device.

[0053] 2. The structural design of the pressure-boosting mechanism of the present invention enables the device to appropriately increase pressure and sink the pile foundation when it is difficult to sink, thereby accelerating the construction progress.
