Description

Technical Field

[0001] The utility model relates to the technical field of PHC pipe piles, and particularly relates to a prefabricated PHC pipe pile. Background Technique

[0002] The PHC pipe pile is a kind of hollow cylindrical concrete precast member made by the process of pre-tensioned centrifugal forming and cured by atmospheric pressure steam. Because it has strong adaptability to the geological conditions with large fluctuations in the bearing stratum, it has a wide range of applications and various building types, and is widely used in the foundations of projects such as railways, highways and bridges, ports, docks, water conservancy, and municipal engineering. It is an essential pile foundation component in various large-scale construction projects. As shown in a precast PHC pipe pile (publication number CN210315506U) disclosed by the Chinese Patent Network, in the process of integral assembly of such a device, a limiting pipe is used as a vertical guiding component for the installation of the upper and lower pile bodies, and the upper and lower pile bodies are integrally combined by the engagement of the upper and lower toothed end faces. Then, two groups of annular connecting plates are used to clamp the upper and lower pile bodies in a butting manner, so that the upper and lower pile bodies are integrally connected in sequence to ensure that the connection between the upper and lower pile bodies is tight and not easily damaged.

[0003] However, for the PHC pipe piles adopted in the above-mentioned disclosed patents and the existing market, there are still some deficiencies: the existing method of integrally connecting the upper and lower pile bodies by using external hoop components has a relatively cumbersome operation, takes a long time, and because the upper and lower pile bodies are in a pressing device, the operation space is small and the operation risk is high. Therefore, the technical personnel in this field provide a prefabricated PHC pipe pile to solve the problems raised in the above background technique. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a prefabricated PHC pipe pile, which can effectively solve the problem of relatively cumbersome integral assembly operation of the PHC pipe pile in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a prefabricated PHC pipe pile, including a concrete casting body;

[0009] The rotary buckle includes an alignment insertion block and a dislocation clamping block, and the alignment insertion block and the dislocation clamping block are integrally arranged.

[0010] As a further solution of the present invention: the rotating slot and the rotating buckle are both L-shaped structures.

[0011] As a further solution of the utility model: the size of the groove body of the sinking groove is the same as the size of the rotating buckle, and the size of the groove body of the dislocation groove is the same as the size of the dislocation block.

[0025] Please refer to Figure 1-5 As shown, a prefabricated PHC pipe pile includes a concrete casting body 1;

[0026] The bottom pile head 2 is provided at one end of the column of the concrete casting body 1, and the top pile head 3 is provided at the other end of the column of the concrete casting body 1. The bottom of the pile body of the bottom pile head 2 is symmetrically provided with two groups of rotating buckles 5, and the pile body of the top pile head 3 is symmetrically provided with two groups of rotating slots 4. The rotating slots 4 and the rotating buckles 5 are both L-shaped structures. The two groups of rotating slots 4 and the two groups of rotating buckles 5 are arranged symmetrically at 180°. In the process of sequentially sinking and assembling the PHC pipe piles, after the pipe piles of the upper group are sunk into the foundation, the pipe piles of the next group are placed vertically opposite to each other in the same way, so that the upper and lower pipe piles remain vertically opposite to each other, and then, the rotating buckle 5 of the upper pipe pile is aligned with the rotating slot 4 of the lower pipe pile, and the rotating buckle 5 is inserted into the rotating slot 4 and rotated to keep the buckle abutting state between the two, and then the upper and lower groups of pipe piles are connected as a whole in the form of self-rotating buckles, and can be assembled by themselves without the help of external components.

[0027] The rotating slot 4 includes a sinking slot 41 and an offset slot 42, and the sinking slot 41 and the offset slot 42 are connected to each other. The rotating buckle 5 includes a mating plug-in block 51 and an offset block 52, and the mating plug-in block 51 and the offset block 52 are integrally arranged. The size of the slot body of the sinking slot 41 is the same as that of the rotating buckle 5, and the size of the slot body of the offset slot 42 is the same as that of the offset block 52. In the process of connecting the upper and lower pipe piles as one, when the rotating buckle 5 is sunk and inserted into the sinking slot 41 of the rotating slot 4, the offset block 52 in the rotating buckle 5 is horizontally aligned with the offset slot 42 in the rotating slot 4. At this time, rotating the upper pipe pile can push the offset block 52 to rotate and insert it into the offset slot 42, so that the upper and lower pipe piles are assembled and connected as one.

[0028] The pile body of the bottom pile head 2 is provided with an alignment mark A6 along the tail end direction of the dislocation block 52, and the pile body of the top pile head 3 is provided with an alignment mark B7 along the notch direction of the dislocation groove 42. When the rotating buckle 5 is buckled with the rotating slot 4, the alignment state of the alignment mark A6 on the bottom pile head 2 and the alignment mark B7 on the top pile head 3 can be observed. When the two are overlapped and aligned, the surface rotating buckle 5 and the rotating slot 4 are completely buckled and installed.

[0029] The working principle of the utility model is as follows: when installing the PHC pipe pile sinking pipe, the pipe piles are sequentially sunk by using impact or static pressure equipment, and after the pipe piles of the previous group are sunk into the foundation, the pipe piles of the next group are vertically placed opposite to each other in the same way, so that the upper and lower pipe piles are kept vertically opposite to each other, and then, the rotating buckle 5 of the upper pipe pile is kept aligned with the rotating slot 4 of the lower pipe pile, and the rotating buckle 5 is inserted into the rotating slot 4;

[0030] Furthermore, after the rotating buckle 5 is sunk and inserted into the sinking groove 41 of the rotating slot 4, the misaligned block 52 in the rotating buckle 5 is kept horizontally aligned with the misaligned slot 42 in the rotating slot 4. At this time, the upper pipe pile is rotated to push the misaligned block 52 to rotate and insert it into the misaligned slot 42, so that the rotating buckle 5 and the rotating slot 4 misaligned buckles relative to each other are connected, and then the upper and lower pipe piles are assembled and connected as a whole. It can be connected as a whole in the form of a self-rotating buckle, and can be assembled by itself without the help of external components. After the assembly is completed, the upper and lower groups of pipe piles can be welded as a whole using welding equipment, and then the pipe piles can be installed in the same way, connected as a whole in sequence, and sunk deep into the foundation. The operation is simple and convenient, and the operation risk is relatively low.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
