[0002] PHC piles are prestressed high-strength concrete piles. There are two main construction methods for PHC piles: hammering and static pressure. Among them, for static pressure construction of PHC piles, after the static pressure pile sinking construction is completed, the piles are usually higher than the ground elevation, so the piles must be cut below the ground elevation first, and then immediately sealed with C25 micro-expansive concrete, and then the pile heads are sealed to prevent people from stepping into the pile holes and getting injured, causing accidental safety accidents, and also prevent soil and sewage from entering the piles and affecting the quality of the later pile core concrete pouring.

[0003] According to the Chinese patent with announcement number: CN220579988U, a prestressed pipe pile head sealing device includes: a lower sealing plate, an upper sealing plate arranged directly above the lower sealing plate and having the same shape and size as the lower sealing plate, a sealing rubber ring arranged around the edge between the lower sealing plate and the upper sealing plate, four pushing components evenly arranged between the sealing plate and the upper sealing plate along the annular direction, a pressure plate arranged directly above the upper sealing plate and having a diameter smaller than that of the upper sealing plate, a vertical push block, a vertical push rod, and a pre-tightening component.

[0004] In the above scheme, the sealing rubber ring can be pushed outward to abut against the inner wall of the prestressed pipe pile head through the cooperation between the pushing assembly, the pressure plate, the vertical push block, the vertical push rod and the pre-tightening assembly, resulting in the following disadvantages: when the sealing device is in use, the resistance force between the sealing rubber ring and the inner wall of the pipe pile head is used as the supporting force of the sealing plate, and the supporting force is not strong enough. When a person accidentally steps on the sealing plate, the sealing plate may move down, resulting in increased safety hazards at the construction site. Utility Model Content

[0010] Preferably, a lifting column is fixed to the top surface of the first blocking plate.

[0011] Preferably, a rubber sleeve is fixed to the outer wall of the lifting column, and the outer wall of the rubber sleeve is provided with anti-slip grooves.

[0013] 1. During use, it is convenient to block the pile head body and to quickly disassemble and assemble the first blocking plate. The two positioning grooves are locked by two positioning columns respectively, which is conducive to providing a stable supporting force for the first blocking plate and preventing the first blocking plate from moving downward, thereby reducing the potential safety hazards at the construction site;

[0023] In use, the staff first pulls the two blocks 6 outwards to make the two positioning columns 5 move away from each other. At this time, the two springs 7 are in a stretched state. Then the staff raises the first blocking plate 1 to the position just above the pipe pile head body 2, and then puts it down vertically until the positioning groove 3 on the first blocking plate 1 corresponds to the positioning hole 4, and then releases the two blocks 6. The spring 7 is used to automatically reset the positioning column 5, so that the positioning column 5 is slidably inserted in the positioning groove 3, and the installation of the first blocking plate 1 is completed; on the contrary, when the staff needs to disassemble the first blocking plate 1, they first pull the two blocks 6 outwards to make the positioning column 5 move away from the inside of the positioning groove 3, and then the first blocking plate 1 can be taken out from the inside of the pipe pile head body 2. It is beneficial to block the pipe pile head body 2, and at the same time, it is convenient to quickly disassemble and assemble the first blocking plate 1. The two positioning grooves 3 are locked by the two positioning columns 5, which is beneficial to provide a stable support force for the first blocking plate 1, and to prevent the first blocking plate 1 from moving down, thereby reducing the safety hazards at the construction site.

[0025] During use, the sliding groove 8 and the sliding rod 9 are used to limit the first sealing plate 1 circumferentially, so as to prevent the first sealing plate 1 from rotating around its own axis, thereby improving the stability of the first sealing plate 1 and assisting in the positioning of the first sealing plate 1, so that the positioning groove 3 of the first sealing plate 1 can correspond to the positioning hole 4, thereby improving the convenience during installation.
