They have the advantages of production automation, high degree of mechanization, fast speed, reliable quality, and strong bearing capacity. They have a short construction period and little impact on the surrounding environment. They can be constructed even in winter when the groundwater level is high. With the continuous development of the construction industry, pipe piles have become one of the most commonly used accessories in the construction industry. When using pipe piles, they need to be connected according to the required length and depth so that multiple piles can be connected to meet the required height.

[0003] When connecting concrete pipe piles, the upper pipe pile needs to be installed on the top of the lower pipe pile, and the two pipe piles need to be accurately aligned on the same vertical axis. When using an auxiliary frame to help connect the pipe piles, due to the inconsistency of the sizes of the upper and lower pipe piles, the existing auxiliary frame needs to manually correct the upper pipe pile multiple times during the process of connecting the two pipe piles before the two pipe piles can be aligned. This operation is not only labor-intensive and seriously affects the progress of the project, but also it is very difficult for the auxiliary frame to fix pipe piles of different sizes, affecting the stability and safety of the connected piles.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Example: Reference Figure 1-7 A statically pressed prestressed concrete pipe pile connection auxiliary frame shown in the figure comprises a connecting column 1, wherein a plurality of slots 2 are provided at the upper and lower ends of the connecting column 1, wherein the radius of the plurality of slots 2 increases step by step from the inside to the outside, and the plurality of slots 2 are all located on the same vertical axis, a plurality of slide grooves 3 are provided on the inner wall of the slot 2, and the plurality of slide grooves 3 are distributed in a circular array, a clamping block 4 is slidably inserted in the slide groove 3, and the cross section of the clamping block 4 is a right-angled trapezoidal structure, and the plurality of clamping blocks 4 are used for clamping the pipe piles, a locking cap 5 is sleeved on the outer part of the upper and lower ends of the connecting column 1, and the connecting column 1 is threadedly connected to the locking cap 5, a through hole 6 is provided in the middle part of the locking cap 5, and the radius of the through hole 6 is equal to the radius of the outermost slot 2, and a reinforcement component is provided on the side of the locking cap 5 away from the connecting column 1, and the reinforcement component is used for reinforcing the pipe pile and the connecting column 1;

[0025] A plurality of slots 2 are provided at the upper and lower ends of the connecting column 1, and the radius of the plurality of slots 2 increases step by step from the inside to the outside, so that the slots 2 can adapt to the insertion of pipe piles of different sizes. In this way, the connecting column 1 can be used for the connection of two pipe piles of different sizes, and can quickly ensure the alignment of the two pipe piles, and the clamping block 4 is taken out and inserted into the slide groove 3. As the clamping block 4 goes deeper, the plurality of clamping blocks 4 can be close to the outer wall of the pipe pile inserted into the slot 2, and as the locking cap 5 is continuously screwed, the locking cap 5 can squeeze the clamping block 4 to clamp the pipe pile, thereby realizing the rapid connection of the two pipe piles, making the pile connection operation more convenient and labor-saving.

[0026] A plurality of auxiliary holes 7 are provided on the peripheral side of the locking cap 5 . With the aid of the auxiliary holes 7 provided as the fulcrums, the worker can insert a stick into the auxiliary holes 7 to help screw the locking cap 5 .

[0027] Among them, a connecting hole is opened inside the connecting column 1, and the connecting hole is used for connecting between the two innermost slots 2. Two grouting pipes 8 are fixed through the connecting column 1, and the two grouting pipes 8 are connected to the connecting hole. Concrete can be injected into the connecting hole along the grouting pipes 8, so that the concrete is filled between the two pipe piles, which can not only improve the self-strength of the connecting column 1, but also enhance the stability of the connection between the two pipe piles.

[0028] The reinforcement assembly includes a plurality of support columns 9, one end of which is fixedly mounted on the locking cap 5, and a ring plate 10 is fixedly mounted on the other end of the plurality of support columns 9, and a plurality of fixing tubes 11 are fixedly mounted on the peripheral side of the ring plate 10, and the plurality of fixing tubes 11 are distributed in a circular array, and bolts 12 are inserted into the fixing tubes 11, and the fixing tubes 11 are threadedly connected to the bolts 12, and one end of the bolt 12 located inside the ring plate 10 is rotatably connected to a clamping plate 13 through a bearing, and a rubber block 14 is fixed to the side of the clamping plate 13 away from the bolt 12;

[0029] The bolt 12 is tightened with a wrench so that the bolt 12 pushes the clamping plate 13 toward the pipe pile. The rubber block 14 on the clamping plate 13 deforms after being pressed against the pipe pile, and the pipe pile is clamped firmly, making the connection between the two pipe piles more stable and making it difficult for the locking cap 5 to rotate, thereby enhancing the stability of the connection between the locking cap 5 and the connecting column 1.

[0030] The working principle of this utility model:

[0031] When in use, first sleeve the locking cap 5 below onto the outside of the lower pipe pile, then sleeve the bottom end of the connecting column 1 onto the lower pipe pile, so that the top end of the lower pipe pile is inserted into the slot 2 of the corresponding size, take out a plurality of clamping blocks 4, and insert them into the corresponding plurality of sliding grooves 3 below, and screw the locking cap 5 onto the connecting column 1, so that during the process of threaded connection between the locking cap 5 and the connecting column 1, the clamping block 4 can be pushed against the lower pipe pile, forcing the clamping block 4 to clamp the lower pipe pile. When screwing the locking cap 5, a stick can be inserted into the force point provided by the auxiliary hole 7 to help screw the locking cap 5 to ensure the stability of the clamping block 4 on the lower pipe pile.

[0032] The upper pipe pile is hoisted to the top of the connecting column 1. As the upper pipe pile continues to move downward, the top of the upper pipe pile is inserted into the slot 2 of the corresponding size, the locking cap 5 on the top is taken out, and it is sleeved on the outside of the upper pipe pile, and multiple clamping blocks 4 are taken out and inserted into the corresponding multiple slide grooves 3 on the top, and the locking cap 5 is screwed onto the connecting column 1 so that the locking cap 5 pushes the clamping block 4 to fit tightly against the upper pipe pile, completing the clamping of the upper pipe pile, and concrete is injected into the connecting column 1 along the grouting pipe 8 so that the concrete fills between the two pipe piles, which not only enhances the strength of the connecting column 1, but also makes the connection between the two pipe piles more stable. Finally, the bolt 12 is tightened with a wrench so that the bolt 12 pushes the clamping plate 13 to move closer to the pipe pile, and the rubber block 14 on the clamping plate 13 is deformed after being close to the pipe pile, and the pipe pile is firmly clamped, making the two pipe piles more stable after being connected.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
