Abstract
Description
Technical Field
[0001] The utility model relates to the field of concrete pipe piles, in particular to an autoclave-free high-performance prestressed 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 pipe piles are mainly used in my country's infrastructure construction to lay a good foundation for various infrastructure construction. When using concrete pipe piles, multiple sections of pipe piles may be required for docking. The conventional docking method is to dock the end plates at both ends of the pipe piles, and then fix them at the docking point by welding or clamping. In this fixing method, the upper and lower pipe piles are face-to-face docking. Because the soil layer of the underground soil at different positions will sink to different degrees over time, the docking point of the upper and lower pipe piles will crack as the soil sinks. After the cracks appear at the docking pipe piles, 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: a high-performance prestressed concrete pipe pile without autoclaving, including pipe pile one and pipe pile two, the outer fixed sleeve at the joint between the pipe pile one and the pipe pile two is provided with a protective sleeve plate, and the joint surface between the pipe pile one and the pipe pile two is provided with a reinforcement piece for improving the joint strength between the pipe pile one and the pipe pile two.
[0005] The beneficial effect of the utility model is that the butt joint mode between the first pipe pile and the second pipe pile is changed from face-to-face butt joint to horizontal plane clamping by using the reinforcement piece, thereby reducing the sinking tendency of the pipe pile caused by underground soil settlement.
[0006] As a further improvement of the utility model, the technical problem to be solved is: how to reduce the sinking tendency of the pipe pile caused by the settlement of the underground soil.
[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the reinforcement part includes two docking plates fixedly arranged on the bottom surface of the second pipe pile in a mirror image and two clamping parts slidingly arranged on the top surface of the pipe pile in a mirror image and clamped with the horizontal plane of the docking plates.
[0008] The beneficial effect of the above improvement is: the connection strength at the joint between the pipe pile 1 and the pipe pile 2 is improved by utilizing the sliding clamping of the clamping piece and the docking plate in the horizontal direction.
[0009] As a further improvement of the utility model, the technical problem to be solved is: how to insert the clamping piece into the corresponding docking plate after the first pipe pile and the second pipe pile are docked.
[0010] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the clamping part includes two clamping plates slidably arranged in the docking plate, the two clamping plates are symmetrically arranged in the center, and a limit plate is integrally provided at one end of the clamping plate away from the corresponding docking plate. A connecting rod is provided between the two clamping plates, and the connecting rods in the two clamping parts are staggered up and down, and the middle parts of the two connecting rods are hinged by a hinge pin, the thickness of the limit plate is the same as the height of the docking plate, and the thickness of the clamping plate is the same as the height of the inner side surface of the docking plate.
[0011] The beneficial effect of the above improvement is that after the pipe pile 2 is hung and connected to the pipe pile 1, the two are opened at the connecting piece by using the expansion tool, and the limit plate is pressed until the clamping plate is completely inserted into the connecting plate.
[0012] The utility model further improves the technical solution adopted as follows: the inner side surface of the limit plate is integrally provided with a guide plate, the inner side surface of the guide plate is in close contact with the inner wall surface of the pipe pile one, a protrusion is provided on the side surface of the bottom end of the guide plate facing the inner wall surface of the pipe pile one, and the inner wall surface of the pipe pile one is provided with a guide ring groove that cooperates with the protrusion.
[0013] The beneficial effects of the above improvement are as follows: the guide plate is used to make the clamping plate slide on the pipe pile around a concentric axis of the pipe pile, and the cooperation between the protrusion and the guide ring groove ensures that the clamping piece only rotates and slides in the horizontal direction and does not move in the vertical direction.
[0014] The utility model further improves the technical solution adopted as follows: the cross-sectional shape of the docking plate is U-shaped, positioning plates are provided at the opposite surfaces of the two docking plates, and the upper and lower ends of the positioning plates protrude from the upper and lower ends of the docking plates.
[0015] The beneficial effect of the above improvement is: the positioning plate is used to pre-position the pipe pile 2 and the pipe pile 1 when they are connected, so that the axes of the pipe pile 1 and the pipe pile 2 are on the same straight line, which is convenient for the subsequent connection between the clamping piece and the connecting plate.
[0016] The utility model further improves the technical solution adopted as follows: when the clamping plate is in the clamping state, a fan-shaped filling plate with the same thickness as the limiting plate is clamped between adjacent limiting plates.
[0017] The beneficial effect of the above improvement is: the filling plate is used to fill every part of the joint between the pipe pile 1 and the pipe pile 2, ensuring that the force at the joint between the pipe pile 1 and the pipe pile 2 is uniform. BRIEF DESCRIPTION OF THE DRAWINGS

A reinforcing member for improving the joint strength of the pipe pile 1 and the pipe pile 2 is provided at the joint surface of the pipe pile 1 and the pipe pile 2. The reinforcing member includes two joint plates 3 fixedly arranged on the bottom surface of the pipe pile 2 and two clamping members slidingly arranged on the top surface of the pipe pile 1 and clamped with the horizontal plane of the joint plate 3. The clamping member includes two clamping plates 4 slidingly arranged in the joint plate 3. The two clamping plates 4 are centrally symmetrically arranged. A limiting plate 5 is integrally provided at one end of the clamping plate 4 away from the corresponding joint plate 3. A connecting rod 7 is provided between the two clamping plates 4. The connecting rods 7 in the two clamping members are staggered up and down. The middle parts of the two connecting rods 7 are hinged by a hinge pin 9. The thickness of the limiting plate 5 is the same as the height of the joint plate 3. The thickness of the clamping plate 4 is the same as the height of the inner side surface of the joint plate 3. The inner side of the limit plate 5 is integrally provided with a guide plate 6, and the inner side of the guide plate 6 is in close contact with the inner wall of the pipe pile 1. A protrusion is provided on the side of the bottom end of the guide plate 6 facing the inner wall of the pipe pile 1, and a guide ring groove 12 is provided on the inner wall of the pipe pile 1 to cooperate with the protrusion. The cross-sectional shape of the docking plate 3 is U-shaped, and the opposite surfaces of the two docking plates 3 are provided with a positioning plate 8, and the upper and lower ends of the positioning plate 8 protrude from the upper and lower ends of the docking plate 3. When the clamping plate 4 is in the clamping state, a fan-shaped filling plate 10 with the same thickness as the limit plate 5 is clamped between adjacent limit plates 5.
[0028] The reinforcement member is used to change the docking mode of pipe pile 1 and pipe pile 2 from face-to-face docking to horizontal clamping, so as to reduce the sinking tendency of pipe pile caused by underground soil settlement. The horizontal sliding clamping of the clamping member and the docking plate 3 is used to improve the connection strength of the docking point between pipe pile 1 and pipe pile 2.
