The first horizontal rod 32 and the second horizontal rod 33 are both screwed and matched with the horizontal sleeve 31. The first horizontal rod 32 is hinged to the ground anchor 4. A connecting piece can be welded on the first horizontal rod 32. Use a bolt assembly to be hinged to the ground anchor and realize the detachable connection between the horizontal adjustment assembly 3 and the ground anchor 4, which is convenient for disassembly and recovery after construction.

[0029] The second horizontal rod 33 passes through the fixing pad 2 and is hinged to the bottom of the casing 1. Mounting pieces may be provided on the casing 1, and mounting rings may be provided on the second horizontal rod 33. The mounting rings can be hinged to the mounting pieces through bolt assemblies, realizing the detachable connection between the horizontal adjustment assembly 3 and the casing 1, which is convenient for disassembly and recycling after construction.

[0030] By rotating the horizontal sleeve 31, the lengths of the first horizontal rod 32 and the second horizontal rod 33 within the horizontal sleeve 31 can be adjusted, thereby adjusting the total length of the horizontal adjustment assembly 3 and realizing the adjustment of the horizontal support strength of the ground anchor 4 on the casing 1. The thread spiral directions at both ends of the horizontal sleeve 31 may be opposite. By rotating the horizontal sleeve 31, the lengths of the first horizontal rod 32 and the second horizontal rod 33 within the horizontal sleeve 31 can be increased or decreased simultaneously, improving the adjustment speed.

[0031] The inclined adjustment assembly 5 includes an inclined sleeve 51. The first inclined rod 52 and the second inclined rod 53 are respectively provided at both ends of the inclined sleeve 51. The first inclined rod 52 is hinged to the ground anchor.

The mounting rings can be hinged to the mounting pieces through bolt assemblies, realizing the detachable connection between the inclined adjustment assembly 5 and the casing 1, which is convenient for disassembly and recycling after construction.

[0033] By rotating the inclined sleeve 51, the lengths of the first inclined rod 52 and the second inclined rod 53 within the inclined sleeve 51 can be adjusted, thereby adjusting the total length of the inclined adjustment assembly 5 and realizing the adjustment of the inclined support strength of the ground anchor 4 on the casing 1; at the same time, it can form a triangular support structure with the horizontal adjustment assembly 3 and the side wall of the casing 1, further enhancing the inclination resistance of the casing 1 and ensuring its stability during construction.

[0034] In some embodiments, the thread spiral directions at both ends of the inclined sleeve 51 are opposite. By rotating the inclined sleeve 51, the lengths of the first inclined rod 52 and the second inclined rod 53 within the inclined sleeve 51 can be increased or decreased simultaneously, improving the adjustment speed of the inclined adjustment assembly 5.

[0035] The specific working principle is as follows:

[0036] First, place the casing 1 at the set position, place the fixing pad 2 at the predetermined position, and use the spike teeth 24 to anchor into the soil to ensure the stability of the fixing pad 2, and install the ground anchor 4.

[0037] Pass the second horizontal rod 33 through the cushion block 22 and hinge it to the casing 1. Hinge the first horizontal rod 32 and the first diagonal rod 52 to the ground anchor 4, and hinge the second diagonal rod 53 to the casing 1. Connect the first horizontal rod 32 and the second horizontal rod 33 with the horizontal sleeve 31, and connect the first diagonal rod 52 and the second diagonal rod 53 with the diagonal sleeve 51 to achieve the preliminary connection of the casing 1, the ground anchor 4, the horizontal adjustment assembly 3 and the diagonal adjustment assembly 5.

[0038] Rotate the horizontal sleeve 31 and the diagonal sleeve 51 to adjust the lengths of the horizontal adjustment assembly 3 and the diagonal adjustment assembly 5, so that the horizontal adjustment assembly 3, the ground anchor 4, the diagonal adjustment assembly 5 and the casing 1 form a triangular support structure.

[0039] During the process of rotary drilling pile formation, the auxiliary device always restricts and fixes the three-dimensional position of the casing 1, thus ensuring that problems such as displacement, loosening and detachment of the casing 1 will not occur, which is beneficial to controlling the pile position deviation and verticality and improving the pile formation quality.
