[0020] Please see Figures 1-4 A PHC pipe pile anti-pile core blockage sealing device includes a connecting body 1, with sealing cylinders 2 movably installed on both the upper and lower sides of the connecting body 1. Fixing mechanisms 4 are provided on both sides of the connecting body 1. A clamping mechanism 5 is provided on the surface of the sealing cylinder 2. Threaded grooves 12 are provided on both the upper and lower sides of the connecting body 1. Threaded rings 11 are movably installed in the inner cavity of the threaded grooves 12 via threads. The opposite sides of the two threaded rings 11 are fixedly connected to the sealing cylinder 2. The fixing mechanism 4 includes several threaded rods 6, which are fixedly installed on the surface of the connecting body 1 via bearings. The clamping mechanism 5 includes several mounting grooves 14, which are formed on the surface of the sealing cylinder 2.

[0021] Please see Figure 1 and Figure 2 The surfaces of the two threaded rods 6 are threaded with threaded plates 8, and connecting support plates 9 are fixedly connected to both sides of the threaded plates 8. Fixing plates 10 are fixedly installed on the opposite side of the two connecting support plates 9.

[0022] Please see Figure 2 An anti-slip plate 19 is fixedly connected to the surface of the fixing plate 10. The surface of the anti-slip plate 19 is provided with an anti-slip groove. By setting the anti-slip plate 19, the anti-slip property of the surface of the fixing plate 10 can be increased, thereby increasing the stability of the fixing plate 10 in clamping.

[0023] Please see Figure 3 The inner cavity of the connecting body 1 has storage slots 13 on both sides, and the two threaded rods 6 are fixedly connected to rotating disks 7 on opposite sides. By setting the storage slots 13, the fixed plate 10 can be stored. By setting the rotating disks 7, it is convenient for the user to rotate the threaded rods 6.

[0024] Please see Figure 4 A spring 15 is fixedly connected to the inner cavity of the mounting groove 14, and a clamping block 18 is fixedly installed on the opposite side of the two springs 15.

[0025] Please see Figure 4 Limiting grooves 17 are provided on both sides of the inner cavity of the mounting groove 14, and limiting protrusions 16 are fixedly connected to both sides of the clamping block 18. Through the cooperation of the limiting grooves 17 and the limiting protrusions 16, the clamping block 18 can be guided and limited to prevent it from falling out of the mounting groove 14.

[0027] In use, the user first replaces the sealing cylinder 2 according to the diameter of the pipe pile. Then, the user screws the threaded ring 11 into the threaded groove 12 through the sealing cylinder 2, thus installing the corresponding model of sealing cylinder 2 onto the connecting body 1. After replacing the sealing cylinder 2, the user inserts the sealing cylinder 2 into the pipe pile through the connecting body 1, allowing the sealing cylinder 2 to block the inside of the pipe pile. During blocking, the sealing rubber ring 20 will cooperate with the sealing cylinder 2 to perform the sealing operation inside the pipe pile. At the same time, the clamping block 18 will also clamp the inner wall of the pipe pile through the rebound force of the spring 15, thereby increasing the sealing cylinder's effectiveness. 2. Stability during sealing, and also prevents the sealing cylinder 2 from moving out of the pipe pile at will. During sealing, the connecting body 1 will also be sleeved on the top of the pipe pile, so that the connecting body 1 can cover the pipe opening of the pipe pile. When covering, the user can also rotate the threaded rod 6 by rotating the rotating disk 7, so that the threaded rod 6 can drive the connecting support plate 9 and the fixing plate 10 to move through the threaded plate 8 until the fixing plate 10 can drive the anti-slip plate 19 to clamp and limit the pipe pile, so that the fixing plate 10 can cooperate with the clamping block 18 to limit the equipment, thereby increasing the firmness of the equipment during sealing.
