DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4As shown, this embodiment is a foundation pile, including a pile body 1, a pile tip 2 is connected to the bottom of the pile body 1, a receiving chamber 3 is arranged in the pile body 1, a screw rod 4 is rotatably connected to the center of the receiving chamber 3, a nut seat 5 is symmetrically screwed on the upper and lower outer walls of the screw rod 4, a through groove 6 is opened around the cavity wall of the receiving chamber 3, a side baffle plate 7 is inserted in the through groove 6, a traction rod 8 is hinged between the side baffle plate 7 and the nut seat 5, a positioning ring 9 is sleeved on the outside of the pile body 1, and an L-shaped rod 10 is connected around the outer wall of the positioning ring 9.

[0021] A stepped hole 11 is provided at the top of the pile body 1, and the lower part of the stepped hole 11 is rotatably connected to the screw rod 4 through a bearing. A hexagonal countersunk hole 41 is provided at the upper end of the screw rod 4, and a hexagonal steel rod 42 is detachably inserted in the hexagonal countersunk hole 41. An operating rod 43 is connected to the upper end of the hexagonal steel rod 42 to facilitate the control of the rotation of the screw rod 4.

[0022] The inner wall of the positioning ring 9 is connected with guide strips 91 around it, and the outer wall of the pile body 1 is provided with a slideway 12 matched with the guide strips 91. The slideway 12 is staggered with the through groove 6 to ensure that the pile body 1 extends vertically into the soil.

[0023] The outer wall of the side baffle plate 7 extending into the accommodating cavity 3 is connected with a stopper 71, and the side baffle plate 7 extending out of the accommodating cavity 3 is provided with a tip structure to facilitate extending into the soil layer.

[0024] The length dimension of the upper end of the through groove 6 from the upper end of the pile body 1 is greater than the thickness dimension of the positioning ring 9 to avoid interference with the extension of the side baffle 7.

[0025] The upper and lower threads of the screw rod 4 are arranged in opposite directions, and the two nut seats 5 can move closer after rotation.

[0026] The specific implementation of the utility model is:

[0027] When the device is in use, the vertical end of the L-shaped rod 10 is extended into the soil surface so that the positioning ring 9 remains horizontal, and the pile body 1 is extended into the soil along the opening of the positioning ring 9. The pile tip 2 is used to reduce the difficulty of breaking the ground. The slideway 12 is used in conjunction with the guide strip 91 for limiting guidance to ensure that the pile body 1 can be buried vertically downward in the soil. When the upper end of the pile body 1 is flush with the upper end of the positioning ring 9, the hexagonal steel rod 42 is extended into the hexagonal countersunk hole 41 along the stepped hole 11, and the hexagonal steel rod 42 is driven to rotate by the operating rod 43. After the screw rod 4 rotates synchronously, the two nut seats 5 move closer, and after the upper and lower sets of traction rods 8 are deflected, the side baffle plate 7 extends out of the pile body 1 along the through groove 6. The end of the side baffle plate 7 adopts a pointed end structure, which is convenient for extending into the surrounding soil layer, which can further prevent the pile body 1 from tilting and ensure the use effect. After the foundation pile installation is completed, the hexagonal steel rod 42 and the positioning ring 9 can be removed.
