DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1

[0022] Reference Figure 1-5 A foundation pile fastening device comprises a first fastening seat 1 and a second fastening seat 2. The first fastening seat 1 and the second fastening seat 2 are both provided with a pair of receiving holes 3 for receiving a steel cable 4. The steel cable 4 is clamped together by the receiving holes 3. Figure 1 As shown, a protective pad 11 is fixedly installed inside the receiving hole 3, and the protective pad 11 is sleeved on the outside of the steel cable 4. The protective pad 11 is a rubber pad, which can protect the steel cable 4 and prevent wear between the steel cable 4 and the inner wall of the receiving hole 3, and can extend the service life of the first fastening seat 1, the second fastening seat 2 and the steel cable 4. A hoop 10 is fixedly sleeved on the outer side of the end of the steel cable 4, and the end of the steel cable 4 can be fixed by the hoop 10. The inner surface of the first fastening seat 1 and the second fastening seat 2 is arc-shaped, and an anti-skid pad is fixedly installed on the arc surface. The inside of the anti-skid pad is made of rubber. The first fastening seat 1 and the second fastening seat 2 will tighten the foundation pile under the tightening action of the steel cable 4. The anti-skid pad can increase the friction between the first fastening seat 1 and the second fastening seat 2 and the foundation pile, and can effectively prevent the foundation pile from sliding between the fastening seat.

[0023] A sliding cavity 5 is opened inside the first fastening seat 1, and a support rod 6 is slidably arranged inside the sliding cavity 5. The cross-section of the support rod 6 is square. The support rod 6 can only slide in the sliding cavity 5 but cannot rotate. The end of the support rod 6 extends through the outside of the first fastening seat 1 and is fixedly connected to the second fastening seat 2. The support rod 6 connects the first fastening seat 1 and the second fastening seat 2 together, and the distance between the first fastening seat 1 and the second fastening seat 2 can be changed.

[0024] A rotating cavity 7 is provided inside the second fastening seat 2 on one side, and a thread groove 9 is provided on the surface of the second fastening seat 2 on the other side. A rotating rod 8 is provided inside the rotating cavity 7 for rotation. The cross section of the rotating rod 8 is circular. The rotating rod 8 can both rotate and slide in the rotating cavity 7. The support rod 6 and the rotating rod 8 are located in the same plane. The end of the rotating rod 8 extends through and extends to the outside of the second fastening seat 2 on this side and is connected with the thread inside the thread groove 9. By rotating the rotating rod 8, the rotating rod 8 can be matched with the thread groove 9, so that the second fastening seats 2 on both sides are connected, and the distance between the second fastening seats 2 on both sides can be changed, so that the distance between the first fastening seats 1 on both sides can also be adjusted. In addition, the rotating rod 8 and the thread groove 9 can be removed, so that the first fastening seats 1 and the second fastening seats 2 on both sides can be disassembled and separated, which is convenient for disassembly and assembly.

[0025] Under the support of the support rod 6 and the rotating rod 8, the distance between the first fastening seat 1 and the second fastening seat 2 can be changed, so that foundation piles of different diameters can be fastened. The first fastening seat 1 and the second fastening seat 2 are slidably connected at the bottom with a base mechanism, which is fixedly connected to the geological layer. The geological layer can be cast by cement and is used to fix the foundation piles. The base mechanism is used to fix the positions of the first fastening seat 1 and the second fastening seat 2.

[0026] Working principle: During use of the foundation pile fastening device, the first fastening seat 1 on one side and the second fastening seat 2 on one side are placed on one side of the foundation pile, and the first fastening seat 1 on the other side and the second fastening seat 2 on the other side are placed on the other side of the foundation pile. By rotating the rotating rod 8 and cooperating with the threaded groove 9, the first fastening seat 1 and the second fastening seat 2 on one side can be connected with the first fastening seat 1 and the second fastening seat 2 on the other side. In this embodiment, two support rods 6 and a rotating rod 8 are provided. The fastening seat may rotate around the rotating rod 8. In order to avoid this situation, two rotating rods 8 can be provided to increase stability. Then, the end of the tightened steel cable 4 is fixed by the hoop 10. The steel cable 4 will drive the fastening seat to tighten. The foundation pile can be fastened through the fastening seat. Finally, the base mechanism is fixedly connected to the geological layer, and the bottom of the foundation pile is fixedly connected to the geological layer, so that the foundation pile and the fastening seat can be fixed, thereby improving the fastening effect of the foundation pile.
