Therefore, slope support, reinforcement and protection measures must be taken.

[0003] In existing technologies, anchored grid beams are commonly used to reinforce slopes, while conventional anchors are mostly composed of individual steel bars, which have relatively limited functionality. Utility Model Content

[0004] The purpose of this utility model is to provide a slope support anchor structure, which aims to solve the problem that the wall support frame has a relatively simple function in the existing technology.

[0005] This utility model is implemented as follows: a slope support anchor structure includes an anchor rod, an anchor hole opened at the slope, and a lattice column. The anchor rod includes an internal section implanted in the anchor hole and an external section extending outside the anchor hole. The internal section of the anchor rod is provided with a centering structure. The external section of the anchor rod is implanted in the lattice column. Two mutually symmetrical bent strips are connected to the external section of the anchor rod. A steel wire rope is connected to the external section of the anchor rod by a stainless steel buckle and a U-shaped block. A steel wire rope loop is formed at the end of the steel wire rope away from the anchor rod.

[0006] Preferably, the two bent strips are L-shaped, and both bent strips are welded to the anchor rod.

[0021] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0022] The slope support anchor 1 structure includes an anchor 1, an anchor hole 12 opened at the slope, and a lattice column 11. The anchor 1 includes an internal section implanted in the anchor hole 12 and an external section extending out of the anchor hole 12. The internal section of the anchor 1 is provided with a centering structure. The external section of the anchor 1 is implanted in the lattice column 11. Two mutually symmetrical bent strips 2 are connected to the external section of the anchor 1. A steel wire rope 3 is connected to the external section of the anchor 1 through a stainless steel buckle 4 and a U-shaped block 19. A steel wire rope loop is formed at the end of the steel wire rope 3 away from the anchor 1.

[0023] The bending strip 2 makes the connection between the outer section of the anchor rod 1 and the lattice column 11 more stable. The centering structure makes it easier to keep the inner section accurately positioned in the anchor hole 12, so that the anchor rod 1 can be well centered in the anchor hole 12. After the concrete is poured, the anchor rod 1 can better transfer the slope sliding force, soil pressure and rock pressure to the stable stratum, thus ensuring the stability of the slope.

[0024] Specifically, in this embodiment, the two bent strips 2 are L-shaped and both bent strips 2 are welded to the anchor rod 1. The bent strips 2 are HRB400 steel bars with a diameter of C22mm and the anchor rod 1 is HRB400 steel bars with a diameter of C28mm.

[0025] The provided bending strip 2 makes the connection between the outer section of the anchor rod 1 and the lattice column 11 more stable.

[0026] Specifically, in this embodiment, the centering structure includes a fixing ring 5 installed on the anchor rod 1. Four first connecting rods 6 are arranged at intervals along the circumferential direction on the fixing ring 5. Second connecting rods 7 are rotatably installed on the first connecting rods 6. The same movable ring 9 is installed on the four second connecting rods 7. Two clamping blocks 10 are rotatably installed on the movable ring 9.

[0027] By cooperating with the fixed ring 5, movable ring 9, first connecting rod 6, and second connecting rod 7, the movable ring 9 can slide on the anchor rod 1, thereby changing the distance between the connection point of the first connecting rod 6 and the second connecting rod 7 and the anchor rod 1. This allows for adjustment of the centering structure for anchor holes 12 of different diameters, enabling the anchor rod 1 to be better centered within the anchor hole 12. After adjustment, the anchor rod 1 can be clamped by the clamping block 10, thus restricting the position of the movable ring 9.

[0028] Specifically, in this embodiment, the movable ring 9 is slidably sleeved on the anchor rod 1, and the movable ring 9 is provided with a plurality of connecting parts 16 that are connected to the second connecting rod 7.

[0029] The connecting piece 16 allows the second connecting rod 7 to rotate along the movable ring 9.

[0030] Specifically, in this embodiment, each of the four second connecting rods 7 is provided with an arc-shaped abutment block 8, which is welded to the second connecting rod 7.

[0031] By setting the arc-shaped abutment block 8, it is easy for the arc-shaped abutment block 8 to contact the inner wall of the anchor hole 12 after the connection between the second connecting rod 7 and the first connecting rod 6 protrudes. This reduces the friction between the connection between the second connecting rod 7 and the first connecting rod 6 and the inner wall of the anchor hole 12, which would prevent the anchor rod 1 from being centered in the anchor hole 12.

[0032] Specifically, in this embodiment, both clamping blocks 10 are rotatably mounted on the movable ring 9 via rotating blocks 17.

[0033] Specifically, in this embodiment, the fixed ring 5 is provided with four rotating grooves 18, and the four first connecting rods 6 are respectively rotatably installed in the four rotating grooves 18.

[0034] The rotating groove 18 allows the first connecting rod 6 to rotate along the rotating groove 18.

[0035] Specifically, in this embodiment, the two clamping blocks 10 are connected and fixed by fixing bolts 14 and nuts 15, and both clamping blocks 10 are provided with arc-shaped grooves that are compatible with the anchor rod 1.

[0036] The fixed bolts 14 and nuts 15 make it easy for the two clamping blocks 10 to be clamped onto the anchor rod 1, thereby restricting the position of the movable ring 9.

[0037] Specifically, in this embodiment, the inner wall of the arc-shaped groove on the clamping block 10 is provided with a plurality of anti-slip grooves 13 spaced apart, and the inner wall of the arc-shaped groove is covered with a rubber anti-slip layer.

[0038] The anti-slip groove 13 and the rubber anti-slip layer allow the clamping block 10 to be better clamped onto the anchor rod 1, preventing the position of the movable ring 9 from changing.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
