[0022] The utility model discloses an anchor foundation which can effectively reduce soil erosion of a pole tower, comprising an anchor body 1, a pad 2, a nut 3 and a protective cap 6, wherein the pad 2 is in a square structure, and a through hole 4 is provided in the middle thereof for the anchor body 1 to pass through, and the anchor body 1 is in a rod-shaped structure with a thread provided on the outer wall; the inner thread of the nut 3 is matched and meshed with the outer thread of the anchor body 1; a connecting ring 5 is provided in the middle of the upper surface of the pad 2, the inner diameter of the connecting ring 5 is equal to the inner diameter of the through hole 4, and the outer wall of the connecting ring 5 is provided with an external thread; a cylindrical groove 61 is provided at the bottom of the protective cap 6, the inner diameter of the groove 61 is equal to the outer diameter of the connecting ring 5, and an inner thread matching the outer thread of the outer wall of the connecting ring 5 is provided below the inner wall of the groove 61, and the protective cap 6 is provided with a cylindrical groove 61 ... at the bottom thereof, and the protective cap 6 is provided with a cylindrical groove 61 at the bottom thereof, and the inner diameter of the groove 61 is equal to the outer diameter of the connecting ring 5, and the inner thread matching the outer thread of the outer wall of the connecting ring 5 is provided below the inner wall of the groove 61, and the protective cap 6 is provided with a cylindrical groove 61 at the bottom thereof, and the protective cap 6 is provided with a cylindrical groove 61 at the bottom thereof, and the protective cap 6 is provided with a cylindrical groove 61 at the bottom thereof, The anchor hole 9 is drilled, and then the anchor rod body 1 is inserted into the anchor hole, and then grouting is performed; or the anchor hole 9 is first grouting, and then the anchor rod body 1 is placed in the anchor hole, and then the nut 3 is screwed into the anchor rod body 1 to tighten the pad 2 to seal the anchor hole. Through the reinforcement effect of the anchor rod foundation, the joints and cracks in the ground surrounding rock and the fracture surfaces are connected, thereby improving the strength of the ground around the tower and reducing the possibility of soil and water flow when it is exposed to rain; by arranging a protective cap 6 to be sleeved on the outside of the nut 3, the nut 3 and the connection between the nut 3 and the anchor rod body 1 can be protected, thereby extending its service life, and the nut 3 can also be removed after many years; by arranging a connecting ring 5, it is convenient to fix the protective cap 6, and by tightening the nut 3 and the connecting ring 5, it can be ensured that the pad 2 closes the open end of the anchor hole 9 to prevent grouting from flowing out.

[0023] Furthermore, the outer wall cross-section of the protective cap 6 is a regular hexagonal structure, which can play an anti-slip role, making it convenient for the staff to connect the protective cap 6 and the connecting ring 5 through threads, and also convenient for the staff to tighten or disassemble the protective cap 6 and the connecting ring 5 through tools such as wrenches; the inner diameter of the protective cap 6 is larger than the maximum width of the nut 3, ensuring that the nut 3 can be within the protection range of the protective cap 6 and will not affect the connection between the protective cap 6 and the connecting ring 5.

[0024] Furthermore, the inner wall of the protective cap 6 is coated with anti-corrosion paint, which further protects the nut 3, the connecting ring 5, and the connection between the nut 3 and the anchor body 1, thereby extending their service life.

[0025] Furthermore, a guide member 21 is provided in the middle of the lower surface of the pad 2. The guide member 21 is a conical structure with an outer diameter that gradually decreases from top to bottom, which facilitates the insertion of the pad 2 into the anchor hole 9 and can play a guiding role. Preferably, the guide member 21 is made of rubber material, and its inner diameter is slightly smaller than the outer diameter of the anchor body 1, thereby preventing grouting from flowing out of the gap between the through hole 4 of the pad 2 and the outer wall of the anchor body 1.

[0026] Furthermore, a plurality of positioning members 7 are connected at intervals on the outer wall of the anchor body 1. The positioning members 7 are in an annular structure, and an inner wall thereof is provided with an internal thread matching the external thread on the outer wall of the anchor body 1. The outer diameter of the positioning members 7 is equal to the inner diameter of the anchor hole 9. By providing the positioning members 7, it can be ensured that the anchor body 1 can be inserted along the axis of the anchor hole 9; a plurality of through grooves 71 are provided in an annular array on the outer wall of the positioning member 7. By providing a plurality of through grooves 71, the passage of grouting can be not affected.

[0027] Furthermore, the through groove 71 of the positioning member 7 is an obtuse triangle structure, and a positioning block 72 is formed between adjacent through grooves 71. The positioning block 72 is an isosceles trapezoidal structure with a cross-sectional width gradually increasing from the outside to the inside. While reducing the material used in the positioning member 7, the connection strength of the positioning block 72 is improved.

[0028] Furthermore, a weight-reducing groove 73 is formed on the upper surface of the positioning member 7, which can reduce the production cost and weight of the positioning member 7; at the same time, the weight-reducing groove 73 provided on the upper surface will not affect the grouting from bottom to top.

[0029] Furthermore, a guide cap 8 is connected to the bottom end of the anchor body 1, and the guide cap 8 includes a ring 81 and a guide block 82. The ring 81 is an annular structure, and its inner wall is provided with an internal thread matching the external thread of the anchor body 1; the bottom of the ring 81 is connected to the top of the guide block 82, and the guide block 82 is a hemispherical structure, and its top end is a plane connected to the lower surface of the ring 81. The outer diameter of the ring 81 is equal to the outer diameter of the guide block 82. The guide block 82 is a hemispherical structure, so that when it is fixed to the bottom of the anchor body 1 for guiding, if the anchor body 1 deviates from the center, the guide block 82 is prevented from being inserted into the inner wall of the anchor hole 9.
