Reinforced concrete precast piles have the advantages of being easy to make, high in strength, high in rigidity, and can be made into various cross-sectional shapes. They are a widely used type of pile.

[0003] When the existing precast piles are connected, the longitudinal movement between the upper and lower piles is limited by the hook connection state between the hook-shaped connecting part and the stop rod, and the circumferential movement between the hook-shaped connecting part and the stop rod is limited by the pin shaft, thereby achieving the purpose of convenient connection between the upper pile and the lower pile, and the verticality is high and the stability is good. There is no need for additional welding to fix the upper and lower pile bodies to complete the purpose of precast pile connection, which greatly reduces the workload of operators. However, the stability is poor and the pile connection is not firm, which leads to a weak connection at the precast pile, affecting the stability of the foundation.

[0033] The moving assembly includes a slider 9, which is slidably connected to the outside of the connecting rod 7. The outside of the connecting rod 7 is sleeved with a first spring 8. The slider 9 is fittedly connected to the upper part of the lower fixed ring 3. One end of the first spring 8 is fixedly connected to the bottom of the connecting block 6, and the other end of the first spring 8 is fixedly connected to the upper part of the slider 9.

[0034] By inserting the screw rod 10 into the interior of the installation groove 11 so that it passes through the upper fixing ring 3, and rotating the rotating rod 4 so that the screw rod 10 is screwed into the interior of the lower fixing ring 3, the slider 9, the connecting rod 7 and the connecting block 6 enter the interior of the installation groove 11 in sequence. When the screw rod 10 passes through the lower fixing ring 3, the connecting rod 7 moves at the same time, driving the slider 9 to move out of the interior of the installation groove 11, and the nut 5 is screwed onto the outside of the screw rod 10 to fasten and fix the precast piles, thereby ensuring the stability of the foundation and avoiding subsequent collapse of the building due to loose connections.
