[0002] Prestressed concrete thin-walled pipe piles are an important building material used in construction projects. When used in foundation construction, the prestressed concrete thin-walled pipe piles are buried deep in the foundation, so that the prestressed concrete thin-walled pipe piles can provide higher bearing capacity for the building.

[0003] To this end, the patent specification with the publication number CN219100032U discloses a combined prestressed concrete thin-walled pipe pile, including an upper pipe pile and a lower pipe pile, the bottom of the upper pipe pile is fixed with a fixed sleeve and a plurality of positioning rods, the fixed sleeve is coaxial with the upper pipe pile, and the plurality of positioning rods are distributed circumferentially along the central axis of the upper pipe pile, the top of the lower pipe pile is fixed with a fixed column, and the specification of the fixed column matches the specification of the fixed sleeve, the lower pipe pile is provided with a plurality of slots, each of the positioning rods is inserted into the corresponding slot, and an anti-pullout component is also provided between the upper pipe pile and the lower pipe pile. The advantages are: by setting the positioning rod, the fixed sleeve, the slot and the fixed column, the lower pipe pile can be guided to be plugged in with the upper pipe pile, ensuring that the central axes of the two coincide, and avoiding displacement when connecting the piles; by setting the connecting rod, the arc-shaped vertical plate and the pressure dividing plate, the position of the fixed sleeve and the fixed column in the vertical direction can be limited, that is, the anti-pullout property of the upper pipe pile and the lower pipe pile is increased. The above-mentioned prestressed concrete thin-walled pipe piles have good load-bearing capacity when used, but there are still some problems:

[0004] The above-mentioned prestressed concrete thin-walled pipe piles are assembled by threaded connection of multiple sets of screws when being butt-jointed for use, which makes the butt-joint assembly process relatively complicated. Utility Model Content

[0023] See also Figure 1-Figure 6The utility model provides a prestressed concrete thin-walled pipe pile that is easy to assemble and assemble, including a pipe pile body 1 and a guide groove 2. Both ends of the outer wall of the pipe pile body 1 are provided with guide grooves 2. Both ends of the pipe pile body 1 are fixedly connected with welding plates 3. A first internal threaded plate 5 is arranged above the inside of the pipe pile body 1, and a second internal threaded plate 6 is arranged below the inside of the pipe pile body 1. An auxiliary docking structure 4 is installed above the pipe pile body 1. The auxiliary docking structure 4 includes a docking groove 401, an inner support sleeve 402, a bidirectional threaded rod 403, a support plate 404, a docking plug block 405, a countersunk block 406, a first conical toothed plate 407 and a second conical toothed plate 408. The docking groove 401 is opened at the bottom of one end of the pipe pile body 1, and an inner threaded plate 5 is arranged above the pipe pile body 1. A support sleeve 402, the inner support sleeve 402 is internally rotatably connected to a bidirectional threaded rod 403, the outer side of the inner support sleeve 402 is fixedly connected to a support plate 404, a docking block 405 is fixedly connected to the top of one end of the pipe pile body 1, a countersunk block 406 is internally rotatably connected to the docking block 405, one end of the countersunk block 406 is fixedly connected to a first conical toothed disc 407, an outer side wall of the bidirectional threaded rod 403 is fixedly connected to a second conical toothed disc 408, the docking groove 401 and the docking block 405 are inlaid structures, the inner support sleeve 402 and the bidirectional threaded rod 403 are in a rotating structure, the bidirectional threaded rod 403 and the first internal threaded disc 5 and the second internal threaded disc 6 are both in a threaded connection structure, and the first conical toothed disc 407 and the second conical toothed disc 408 are in a meshing structure.

[0024] See attached Figure 2 , Figure 3 , Figure 4 and Figure 5When the prestressed concrete thin-walled pipe piles are installed and used, the foundation of the building is compacted in advance, and then a group of pipe pile bodies 1 are inserted into the bottom of the foundation through special equipment. When the building to be constructed is high, the pipe piles need to bear more gravity. Therefore, multiple groups of prestressed concrete thin-walled pipe piles are required to be butt-jointed and inserted into the ground to provide stable support for the construction of the building. When commonly used prestressed concrete thin-walled pipe piles are butt-jointed, multiple groups of prestressed concrete thin-walled pipe piles are often butt-jointed end to end and welded, and multiple groups of bolts are used for fastening processing, so that multiple groups of prestressed concrete thin-walled pipe piles are butt-jointed and inserted into the ground. In order to make the butt-jointing of the prestressed concrete thin-walled pipe piles more stable and reduce its operation, for this reason, when the two groups of pipe pile bodies 1 are butt-jointed end to end, the bidirectional threaded rod 403 is inserted into the two groups of pipe pile bodies 1, and the two ends of the bidirectional threaded rod 403 are respectively against the two groups of pipe pile bodies. 1, the second conical toothed disc 408 and the first conical toothed disc 407 will be meshed with each other, and then the countersunk block 406 is rotated using a special wrench or other tool. At this time, the first conical toothed disc 407 will drive the bidirectional threaded rod 403 to rotate by meshing with the second conical toothed disc 408, and the first internally threaded disc 5 and the second internally threaded disc 6 are respectively threadedly connected with the threads at both ends of the outer wall of the bidirectional threaded rod 403. Under the sliding structure of the first internally threaded disc 5, the second internally threaded disc 6 and the guide groove 2, the first internally threaded disc 5 and the second internally threaded disc 6 are moved in the opposite direction along the outer side of the bidirectional threaded rod 403, thereby pulling the two groups of pipe pile bodies 1 to be firmly butted end to end, and the butt groove 401 is matched with the butt plug block 405 during butt joint, and then after welding, the assembly of the prestressed concrete thin-walled pipe pile is more stable and convenient.

[0025] The outer side of the first internal threaded disk 5 is hinged with a reinforcement structure 7, which includes an insertion rod 701, a curved surface 702 and a rib 703. The insertion rod 701 is installed on the outer side of the first internal threaded disk 5. The top of one end of the insertion rod 701 is provided with a curved surface 702, and the other end of the insertion rod 701 is fixedly connected with the rib 703. The insertion rod 701 fits with the inside of the guide groove 2, and the insertion rod 701 and the first internal threaded disk 5 are in a hinged structure.

[0026] See attached Figure 5 and Figure 6When the prestressed concrete thin-walled pipe pile is docked, in order to make it more stable after being inserted into the ground, a plug rod 701 can be installed corresponding to the first internal threaded disk 5 of the topmost pipe pile body 1. When the first internal threaded disk 5 slides along the guide groove 2, due to the arc surface 702 opened on the top of the plug rod 701, the first internal threaded disk 5 will gradually expand outward along the inner side of the guide groove 2 when sliding, and under the action of the ribs 703, the plug rod 701 can quickly break the soil and expand, so that the contact area between the prestressed concrete thin-walled pipe pile and the soil is greatly increased, so that the prestressed concrete thin-walled pipe pile is not easy to be pulled out of the soil and shake after installation.
