Description

Technical Field

[0001] The utility model relates to the field of concrete pipe piles, in particular to an ultra-high-strength concrete pipe pile. Background Art

[0002] Pipe piles are mainly used in my country's infrastructure construction to lay a good foundation for various infrastructure projects. When using concrete pipe piles, multiple sections of pipe piles may need to be butt-jointed. The conventional butt-jointing method is to butt-join the end plates at both ends of the pipe piles, and then fix them at the joints by welding or clamping. In this fixing method, the upper and lower pipe piles are butt-jointed face to face. Because the soil layers of the underground soil at different locations will sink to different degrees over time, the joints of the upper and lower pipe piles will crack as the soil sinks. After cracks appear at the butt-jointed pipe piles, they will gradually evolve into dislocations, which reduces the use effect of the pipe piles. Summary of the invention

[0003] The technical problem to be solved by the utility model is that when concrete pipe piles are in use, multiple sections of pipe piles may need to be butt-jointed. The conventional butt-jointing method is to butt-join the end plates at both ends of the pipe piles, and then fix them at the butt joint by welding or clamping. In this fixing method, the upper and lower pipe piles are butt-jointed face to face. Because the soil layers of the underground soil at different positions will sink to different degrees over time, the butt joints of the upper and lower pipe piles will crack as the soil sinks. After the cracks appear at the butt joints, they will gradually evolve into dislocation, which reduces the use effect of the pipe piles.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: an ultra-high-strength concrete pipe pile, including a pile body and an end plate arranged at the end of the pile body, a positioning ring plate is provided at the bottom of the end plate, and a stepped groove matching the positioning ring plate is provided on the top of the end plate. A plurality of positioning blocks for positioning the upper and lower pile bodies are provided on the top surface of the end plate for radial sliding. A positioning groove for plugging into the positioning block is provided on the positioning ring plate. An adjusting member for pushing a plurality of positioning blocks to be synchronously inserted into the positioning groove is also provided on the top surface of the end plate.

[0005] The beneficial effect of the utility model is that the two pile bodies connected with the upper and lower shaft ends can be positioned radially by utilizing the cooperation of the adjusting piece, multiple positioning blocks and the positioning ring plate, and then with the assistance of subsequent welding, the sinking tendency of the pipe pile caused by underground soil settlement can be better reduced.

[0006] As a further improvement of the utility model, the technical problem to be solved is: how to use the adjustment member to position the two pile bodies in the radial direction.

[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the adjusting member includes a plurality of push blocks rotatably arranged on the top surface of the end plate and used to squeeze the corresponding positioning blocks to move, the outer sleeves of the plurality of push blocks are provided with a connecting ring plate, and the top surface of the end plate is also provided with a connecting ring plate, and the connecting ring plate is provided with a plurality of movable grooves, and an adjusting block fixedly connected to the connecting ring plate is provided in the movable groove along the circumferential sliding direction.

[0008] The beneficial effects of the above improvements are as follows: multiple push blocks connected to the inner ring surface of the connecting ring plate can push the corresponding positioning blocks to move radially, and the adjusting blocks can drive the connecting ring plate to rotate on the top surface of the end plate, and the height of the positioning ring plate is the sum of the height of the connecting ring plate and the depth of the stepped groove.

[0009] The utility model further improves the technical solution adopted as follows: a T-block is arranged on the bottom surface of the positioning block, and a limiting groove which is connected with the stepped groove and cooperates with the T-block is opened on the top surface of the end plate.

[0010] The beneficial effect of the above improvement is that the positioning block and the end plate can be connected together by the cooperation between the T-block and the limiting groove, and the moving direction of the positioning block can be limited.

[0011] The utility model further improves the technical solution adopted as follows: the push block is a special-shaped arc block structure, the positioning block is an L-shaped block structure, and one side edge is provided with a chamfer.

[0012] The beneficial effects of the above improvements are as follows: the push block with the special-shaped arc-shaped block structure can squeeze the positioning block at different positions, so that the positioning block is inserted into the corresponding positioning groove to complete radial positioning; the chamfer set on the positioning block increases the contact area with the push block, making it easier for the push block to push the corresponding positioning block to move.

[0013] The utility model further improves the technical solution adopted as follows: the adjustment block is provided with a plug hole along the radial direction.

[0014] The beneficial effect of the above improvement is that the insertion hole makes it easy for construction workers to use tools to insert into the adjustment block to apply force to drive multiple push blocks to rotate together, thereby improving the docking efficiency of two pipe piles to a certain extent.
