[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-6 ;

[0025] A steel pipe pile foundation reinforcement structure includes a steel pipe pile body 1, the lower end of the steel pipe pile body 1 is configured as a conical head 11, and a reinforcement mechanism 2 is provided inside the steel pipe pile body 1. The reinforcement mechanism 2 can increase the pull-out resistance of the steel pipe pile body 1. By rotating the rotating rod 22, multiple first toothed rods and second toothed rods are guided to extend from the side wall of the steel pipe pile and insert into the soil or undried concrete, thereby increasing the stability of the steel pipe pile body installed on the foundation and increasing the pull-out resistance of the steel pipe pile body.

[0026] The reinforcement mechanism 2 includes a top cover 21, a rotating rod 22, and an extension assembly 26. The top cover 21 is snapped onto the upper end of the steel pipe pile body 1 and fixed by bolts. The top cover 21 is used not only to close the upper end of the steel pipe pile body 1, but also to support the installation of the rotating rod 22. The rotating rod 22 is rotatably installed on the inner wall of the top cover 21. The rotation of the rotating rod 22 drives the gear 29 to rotate. The rotating rod 22 is inserted into the interior of the steel pipe pile body 1. The extension assembly 26 is set inside the steel pipe pile body 1. Extensions are provided at the upper, middle, and lower parts of the steel pipe pile body 1. Component 26 extends the first toothed rod 28 and the second toothed rod 281 from the steel pipe pile body 1 and contact the soil, increasing the installation stability and pull-out resistance of the steel pipe pile body 1. The middle part of the extended component 26 can also be set at a perpendicular angle to the upper and lower extended components 26, so that the first toothed rod 28 and the second toothed rod 281 in the middle part of the steel pipe pile body 1 are crossed with the first toothed rod 28 and the second toothed rod 281 extended from the upper and lower parts, which can further increase the installation stability and pull-out resistance of the steel pipe pile body 1.

[0027] The steel pipe pile body 1 has a support plate 25 installed inside. There are two sets of support plates 25. The support plates 25 are used to support the rotation and limit the rotation of the rotating rod 22, so that the rotating rod 22 can rotate stably without shaking. The rotating rod 22 is rotatably connected to the inner wall of the support plate 25. The upper end of the rotating rod 22 is equipped with a turntable 23. Rotating the turntable 23 facilitates the rotation of the rotating rod 22. The side wall of the steel pipe pile body 1 has a through hole 24. The first toothed rod 28 and the second toothed rod 281 pass through the corresponding through hole 24, so that the first toothed rod 28 and the second toothed rod 281 can extend out of the through hole 24.

[0028] Furthermore, the extension assembly 26 includes a first rack 28, a second rack 281, and a gear 29. The gear 29 is fixedly mounted on the outer wall of the rotating rod 22. The first rack 28 and the second rack 281 are respectively meshed with the gear 29. The gear 29 rotates to push the first rack 28 and the second rack 281, causing the first rack 28 and the second rack 281 to extend outward from the steel pipe pile body 1. The first rack 28 and the second rack 281 move in opposite directions. 81. The steel pipe pile body 1 extends out and inserts into the soil, increasing the stability of the steel pipe pile body 1 on the foundation and increasing its pull-out resistance. A first guide rod 283 and a second guide rod 284 are fixedly installed inside the steel pipe pile body 1. The inner wall of the first toothed rod 28 slides into the first guide rod 283, which supports and guides its movement. The inner wall of the second toothed rod 281 slides into the second guide rod 284, which is used for... The second toothed rod 281 provides support and guidance for movement. A groove 282 is provided on the back of both the first toothed rod 281 and the second toothed rod 281. The grooves 282 are used for guiding and sliding connection with the limiting rod 272. A first limiting plate 27 and a second limiting plate 271 are fixedly installed inside the steel pipe pile body 1. Limiting rods 272 are fixedly installed on both the first and second limiting plates 271. The limiting rods 272 are slidably connected to the grooves 282. Position plate 27 and second limiting plate 271 are used to provide auxiliary support for first toothed rod 28 and second toothed rod 281, as well as guide sliding function. The front ends of first toothed rod 28 and second toothed rod 281 are both set with pointed tips 285, which facilitates the insertion of the front ends of first toothed rod 28 and second toothed rod 281 into soil or undried concrete. When first toothed rod 28 and second toothed rod 281 are inside the steel pipe pile body 1, the pointed tips 285 of first toothed rod 28 and second toothed rod 281 are inserted into the through hole 24 for support.

[0029] The working principle of this utility model is as follows: After the steel pipe pile body 1 is inserted into the foundation, the turntable 23 rotates, thereby driving the rotating rod 22 to rotate. The rotating rod 22 is supported by the support plate 25 inside the steel pipe pile body 1, so that the rotating rod 22 can rotate stably without shaking. The rotating rod 22 drives multiple gears 29 to rotate. The corresponding gears 29 mesh with the corresponding first toothed rod 28 and second toothed rod 281. The first toothed rod 28 is supported by the first guide rod 283 and the first limiting plate 27. The second toothed rod 281 is supported by the second guide rod 284 and the second limiting plate 271. When the first toothed rod 28 and the second toothed rod 281 are inside the steel pipe pile body 1, the tips 285 of the first toothed rod 28 and the second toothed rod 281 are inserted into the through hole 24. The gear 29 rotates, pushing the first toothed rod 28 and the second toothed rod 281. The first toothed rod 28 and the second toothed rod 281 move in opposite directions. The first guide rod 283 and the first limiting plate 27 support the first toothed rod 28 to extend outward, and the second guide rod 284 and the second limiting plate 271 support the second toothed rod 281 to extend outward. The first toothed rod 28 and the second toothed rod 281 pass through the corresponding through holes 24 and extend outward from the inside of the steel pipe pile body 1. The front ends of the first toothed rod 28 and the second toothed rod 281 are both set as pointed tips 285, which facilitates the insertion of the front ends of the first toothed rod 28 and the second toothed rod 281 into the soil or undried concrete, thereby increasing the stability of the steel pipe pile body 1 installed on the foundation and increasing the pull-out resistance of the steel pipe pile body 1.

[0030] In summary, by installing a reinforcement mechanism inside the steel pipe pile, the rotation of the rotating rod drives multiple first and second toothed rods to extend from the side wall of the steel pipe pile and insert into the soil or undried concrete, thereby increasing the stability of the steel pipe pile body installed on the foundation and increasing the pull-out resistance of the steel pipe pile body.
