Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 3, the utility model discloses a high-compressive concrete pipe pile, which includes a first base 1. A first pipe pile 201 is fixedly arranged on the top of the first base 1. A first limiting plate 202 is fixedly arranged on the top of the first pipe pile 201. A second limiting plate 203 is arranged on the top of the first limiting plate 202. A second pipe pile 204 is fixedly arranged on the top of the second limiting plate 203. A second base 205 is fixedly arranged on the top of the second pipe pile 204. Clamping blocks 301 are fixedly arranged on both sides of the top of the first limiting plate 202. A threaded rod 302 is movably arranged inside the clamping block 301. A hexagonal nut 303 is fixedly arranged at one end of the threaded rod 302 away from the clamping block 301. A protective shell 304 is movably arranged outside the hexagonal nut 303. An L-shaped rod 305 is fixedly arranged on the top of the protective shell 304. A moving plate 306 is fixedly arranged at one end of the L-shaped rod 305. A return spring 307 is fixedly arranged on the side of the moving plate 306 away from the L-shaped rod 305. A rotating seat 308 is movably arranged outside the moving plate 306. The connection relationship between the rotating seat 308 and the moving plate 306 is a sliding connection.

[0022] Specifically, hexagonal grooves adapted to the hexagonal nut 303 are respectively formed on opposite sides of the protective shell 304. The connection relationship between the protective shell 304 and the hexagonal nut 303 is an active insertion connection.

[0023] In this embodiment, by setting the hexagonal nut 303 and the protective shell 304, after the hexagonal nut 303 is accurately inserted into the protective shell 304, the purpose of limiting the hexagonal nut 303 is achieved, and at the same time, the hexagonal nut 303 can be protected from being corroded by the influence of a humid environment.

[0024] Specifically, installation grooves adapted to the rotating seat 308 are respectively formed on both sides inside the second limiting plate 203. The connection relationship between the rotating seat 308 and the second limiting plate 203 is a rotating connection.

[0025] In this embodiment, by setting the second limiting plate 203 and the rotating seat 308, when the moving plate 306 rotates, the rotating seat 308 rotates inside the second limiting plate 203 accordingly, so as to facilitate the adjustment of the angle of the protective shell 304.

[0026] Specifically, a reinforcing plate 401 is fixedly arranged at the bottom of the first base 1. A fixing cone 402 is fixedly arranged at the bottom of the reinforcing plate 401.

[0027] In this embodiment, by setting the reinforcing plate 401 and the fixing cone 402, when the first pipe pile 201 is driven into the ground, the fixing cone 402 will move downward accordingly, and the conical fixing cone 402 can improve the moving speed of the first pipe pile 201.

[0028] Specifically, steel spikes 403 are fixedly arranged on the outer wall of the fixed cone 402.

[0029] In this embodiment, by providing the steel spikes 403, when the specified depth is reached, the steel spikes 403 will fix the bottom of the first base 1 to prevent the first pipe pile 201 from shaking and tilting.

[0030] Specifically, a positioning block 404 is fixedly arranged in the middle of the top of the first limiting plate 202.

[0031] In this embodiment, by providing the positioning block 404, the setting of the positioning block 404 enables the first limiting plate 202 and the second limiting plate 203 to be accurately connected, thereby improving the connection stability.

[0032] During use, the first pipe pile 201 is driven into the ground. The fixed cone 402 and the steel spikes 403 at the bottom will fix the first pipe pile 201. Then, the second pipe pile 204 is aligned with the first pipe pile 201 so that the first limiting plate 202 and the second limiting plate 203 are in contact with each other. The clamping block 301 and the positioning block 404 will respectively enter the clamping groove and the positioning groove to ensure the stable connection of the first pipe pile 201 and the second pipe pile 204. Then, the hexagonal nut 303 is rotated until the threaded rod 302 is completely inserted into the clamping block 301. The L-shaped rod 305 is pulled towards the side away from the second limiting plate 203. The moving plate 306 moves in the rotating seat 308, and the return spring 307 is stretched. When the height of the protective shell 304 is higher than the height of the hexagonal nut 303, the L-shaped rod 305 is rotated, and the rotating seat 308 rotates accordingly under the action of the moving plate 306. When the hexagonal groove of the protective shell 304 is aligned with the hexagonal nut 303, the L-shaped rod 305 is released, and the hexagonal nut 303 is inserted into the protective shell 304 under the elastic force of the return spring 307, realizing the protection of the hexagonal nut 303 to prevent it from rusting or corroding, thereby improving the connection stability of the first pipe pile 201 and the second pipe pile 204.

[0033] In summary, for the high-compressive-strength concrete pipe pile, by providing the protective shell 304, the protective shell 304 can not only effectively isolate the threaded rod 302 and the hexagonal nut 303 from direct contact with moisture, oxygen and corrosive substances in the external environment, thereby reducing the risk of rust or corrosion of the threaded rod 302 and the hexagonal nut 303 due to moisture absorption and extending the service life of the threaded rod 302 and the hexagonal nut 303, but also can limit the hexagonal nut 303 to prevent the threaded rod 302 from completely loosening or falling off, effectively enhancing the connection stability between the first pipe pile 201 and the second pipe pile 204 and improving the safety of the device. By providing the L-shaped rod 305, the moving plate 306, the return spring 307 and the rotating seat 308, when maintaining the device, the L-shaped rod 305 is pulled to the side away from the second limiting plate 203, the moving plate 306 moves in the rotating seat 308, and the return spring 307 is stretched. When the height of the protective shell 304 is higher than the height of the hexagonal nut 303, the L-shaped rod 305 is rotated, and the rotating seat 308 rotates accordingly under the action of the moving plate 306, thus removing the protection of the hexagonal nut 303. At this time, the hexagonal nut 303 can be rotated to separate the first pipe pile 201 from the second pipe pile 204. The operation is simple, which is convenient for the staff to maintain the device and significantly improves the work efficiency of the staff.
