[0003] During the construction of PHC pipe piles, it is necessary to install a pile tip at the bottom of the pile. During the construction of the pipe piles, the pile tip can guide and block the pipe piles during the driving process of the PHC pipe piles, ensure the verticality of the PHC pipe piles and prevent soil from entering the interior of the pipe piles. At the same time, it can also prevent the ends of the PHC pipe piles from being damaged. Usually, the pile tip and the end plate at the bottom of the PHC pipe pile are connected by welding. Since this process requires welding tools, the installation method is more troublesome and has certain limitations.

[0004] Therefore, we made improvements and proposed a PHC pile tip. Utility Model Content

[0021] Example: Figure 1-4 As shown, the utility model provides a PHC pipe pile tip 2, comprising an end plate 1 and the pile tip 2, a mounting ring 3 is arranged at the bottom of the end plate 1, a connecting groove 4 is arranged on the outer surface of the mounting ring 3, the connecting groove 4 is composed of a guide groove 401 arranged along the central axis of the mounting ring 3 and a limiting groove 402 arranged at the top of one side of the guide groove 401, a mounting groove 5 is arranged at the pile tip 2, a plurality of connecting blocks 6 are arrayed on the top of the inner wall of the mounting groove 5, and the connecting blocks 6 are connected to the connecting groove 4, so as to realize the connection and fixation between the pile tip 2 and the end plate 1.

[0022] Among them, the outer diameter of the mounting ring 3 is equal to the inner diameter of the mounting groove 5, so that the pile tip 2 can be mounted on the outside of the mounting ring 3, the width of the connecting block 6 is equal to the width of the guide groove 401, the thickness of the connecting block 6 is equal to the thickness of the limiting groove 402, and the connecting block 6 can enter the guide groove 401 and be screwed into the limiting groove 402 at the top of the guide groove 401.

[0023] Among them, there are multiple connecting grooves 4 on the surface of the mounting ring 3 and multiple connecting blocks 6 on the inner wall of the mounting groove 5, and the multiple connecting grooves 4 on the surface of the mounting ring 3 and the multiple connecting blocks 6 on the inner wall of the mounting groove 5 are arranged in an array, and the positions correspond one to one.

[0024] Among them, a limiting hole 7 is opened at the top of the limiting groove 402, a movable groove 8 is opened inside the connecting block 6, a movable block 9 is slidably installed inside the movable groove 8, a limiting pin 11 is set on the top of the movable block 9, and the limiting pin 11 passes through the top of the connecting block 6.

[0025] The position of the limiting hole 7 at the top of the limiting groove 402 corresponds to the position where the limiting pin 11 passes through the top of the connecting block 6 , which facilitates the engagement of the limiting pin 11 with the limiting hole 7 .

[0026] A spring 12 is installed inside the movable groove 8 , and two ends of the spring 12 are respectively against the bottom of the movable block 9 and the bottom of the movable groove 8 , so that the spring 12 can realize the reset rebound of the limit pin 11 .

[0027] Among them, the surface of the end plate 1 is provided with connection holes 101 in an array around the mounting ring 3, and the connecting block 6 is used to connect with the steel cage in the PHC pile, so that the end plate 1 and the PHC pile form a whole, and the surface array of the pile tip 2 is provided with a plurality of guide plates 201. The guide plates 201 can prevent the PHC pile from rotating when the pile tip 2 is driven into the ground, thereby improving the stability of the PHC pile during the driving process.

[0028] Working principle: When installing the pile tip 2, the utility model first aligns the installation groove 5 on the top of the pile tip 2 with the installation ring 3 installed at the bottom of the end plate 1 on the PHC pile and inserts them. The end plate 1 needs to be connected with the steel cage inside the PHC pile through the connection hole 101 before the production and pouring of the PHC pile. After the pouring of the PHC pile is completed, the end plate 1 and the PHC pile form a whole. When the pile tip 2 is inserted into the outside of the installation ring 3, each connection block 6 is aligned with each connection groove. 4 is aligned with the guide groove 401, so that after the mounting ring 3 is completely inserted into the mounting groove 5, each connecting block 6 can move to the top of each guide groove 401. In this process, the limiting pin 11 is squeezed into the movable groove 8 by the inner wall of the top of the guide groove 401. After that, the pile tip 2 is rotated to make each connecting block 6 enter the limiting groove 402. After each limiting pin 11 moves to align with each limiting hole 7, the limiting pin 11 is bounced into the limiting hole 7 under the action of the spring 12, and the installation of the pile tip 2 is completed.
