In this case, a rotary drilling machine can be used to drill holes first, and then the pipe piles can be planted. The holes drilled by the rotary drilling machine can be drilled into the medium weathered rock. The pipe piles can be planted in the medium weathered rock, which can greatly improve the bearing capacity. When planting piles, it is very important to maintain the verticality of the piles, because poor verticality may lead to structural instability or reduced bearing capacity.

[0022] Specifically, the outer casing 1 is the outer protective tube of the entire device, which is annular and is used to store other components inside; the first casing 2 and the second casing 3 are symmetrically arranged inside the outer casing 1 to form a complete annular structure, and they can move relative to each other to accommodate pipe piles 16 of different diameters; a circular pile hole 4 is formed between the first casing 2 and the second casing 3 to accommodate the pipe piles 16; the spring device 5 is located between the first casing 2 and the outer casing 1, and between the second casing 3 and the outer casing 1, and the spring device 5 is used to apply pressure to put the pipe piles 16 in the correct position and ensure verticality and concentricity.
[0023] Furthermore, the first casing 2 and the second casing 3 have the same structure; the first casing 2 includes a semi-circular main cylinder 6; and a top plate 7 is fixedly provided on the top of the main cylinder 6; the bottom of the top plate 7 abuts against the top of the outer casing 1 and the outer edge of the top plate 7 extends out of the outer cylinder; thereby limiting the height direction of the first casing 2 or the second casing 3.
[0024] Specifically, the bottom of the top plate 7 abuts against the top of the outer casing 1 to provide a limiting function in the height direction, preventing the first casing 2 or the second casing 3 from falling into the outer casing 1; the outer edge of the top plate 7 extends out of the outer casing 1 to provide additional protection for the main cylinder 6, preventing external objects from directly contacting or damaging the main cylinder 6, and also preventing the first casing 2 or the second casing 3 from falling into the outer casing 1; the top plate 7 makes the structure of the first casing 2 and the second casing 3 more stable, which helps to maintain their shape and function.
[0025] Furthermore, the spring device 5 includes a fixing member 8, a sliding member 9 that slides with the fixing member 8, and a spring 10 arranged between the fixing member 8 and the sliding member 9; and protruding limit blocks 11 are formed at both ends of the fixing member 8 to limit the sliding stroke of the sliding member 9; and the head end of the fixing member 8 is fixedly connected to the main cylinder 6, and the end of the fixing member 8 abuts against the outer casing 1, so that the main cylinder 6 generates a clamping force on the pipe pile 16.
[0026] Specifically, the spring device 5 is composed of three parts, including a fixing member 8, a sliding member 9 that slides with the fixing member 8, and a spring 10 arranged therebetween, so that the sliding member 9 can make a linear motion under the guidance of the fixing member 8 and is affected by the elastic force of the spring 10; protruding limit blocks 11 are formed at both ends of the fixing member 8 to limit the sliding stroke of the sliding member 9 and ensure that the movement range of the spring device 5 meets the design requirements; the head end of the fixing member 8 is fixedly connected to the main cylinder 6, and the end of the fixing member 8 is in contact with the outer casing 1, so that the main cylinder 6 generates a clamping force on the pipe pile 16, which helps to ensure the position stability and verticality of the pipe pile 16.
[0027] Furthermore, the head end of the fixing member 8 is rotatably connected to a roller 14 ; and the main cylinder 6 is formed with a through slot 15 for the roller 14 to pass through; and after the roller 14 passes through the through slot 15 , it abuts against the pipe pile 16 , so that the pipe pile 16 is steadily planted downward along the roller 14 .
[0028] Specifically, through the contact between the roller 14 and the pipe pile 16, the pipe pile 16 can smoothly descend along the roller 14 during the pile planting process, reducing the instability caused by friction or uneven force, and ensuring the smooth progress of the pile planting process; the use of the roller 14 reduces the contact friction between the pipe pile 16 and the main cylinder 6, thereby reducing the resistance during the descent process, making the pile planting process more efficient; through the through groove 15 on the main cylinder 6, the roller 14 can accurately guide the pipe pile 16 to ensure that the direction of the pipe pile 16 is stable during the descent process and is not easy to deviate from the predetermined trajectory.

[0031] Furthermore, the exterior of the roller 14 is made of a flexible material.
[0032] Specifically, the flexible material can reduce the friction when the roller 14 contacts the pipe pile 16, thereby reducing energy loss and wear and extending the service life of the roller 14; the soft external material can better fit the surface of the pipe pile 16, providing a larger contact area and a more uniform force distribution, thereby increasing stability and reliability during the pile planting process; the flexible material has good shock absorption and vibration reduction properties, which can reduce the noise and vibration generated when the roller 14 contacts the pipe pile 16, and improve the comfort of the working environment; the exterior of the flexible material can better adapt to the surfaces of pipe piles 16 of different diameters and shapes, thereby improving the applicability and flexibility of the device to the pipe piles 16; the flexible material can adopt existing materials, such as rubber, silicone, polyurethane, etc.
