Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of slope anchor rods, and particularly relates to a high-slope anchor rod structure. Background Art
[0002] High slopes mainly include soil slopes and rock slopes, among which soil slopes are the most common. Due to the large height of high slopes and the mostly extremely steep structure of the slopes, the danger of the slopes is very high. Specifically, because the slope surface cannot support, the slope is extremely prone to collapse.
[0003] Especially during the rainy season, such as heavy rain scouring the soil layer structure on the slope, infiltrating into the rainwater, and increasing the lubricity, resulting in the slope being more prone to collapse, debris flow and other dangerous accidents under the scouring of rainwater. Especially for the slopes located on the side of the road, once a collapse or debris flow occurs, it is extremely easy to cause major natural disaster accidents.
[0004] Therefore, at present, the slope is mostly treated by reinforcement methods. Specifically: multiple anchor rods are driven into the soil layer of the slope, and then a steel mesh is supported on the slope. The mesh holes on the steel mesh penetrate through the anchor rods, and the anchor rods are used as fulcrums to stably hang the steel mesh. Then, concrete is poured to form a protective structure. However, it is found after actual construction that especially when the slope is extremely steep and the soil layer is extremely soft, the stability of the anchor rods driven into the slope surface is not high.
[0005] Especially after being scoured by heavy rain, the side slip of the slope soil layer reduces the anchoring stability of the anchor rods. Since the anchor rods are hung with heavy steel meshes, some of the anchor rods on the steel mesh loosen and fall from the soil layer structure, and after loosening, they no longer hang on the steel mesh, resulting in a decrease in the number of fulcrums of the steel mesh. Coupled with the scouring of rainwater, after being used for a period of time, the steel mesh gradually sags and brings a large number of anchor rods to loosen, thereby causing the loss of slope support. It is relatively difficult to re-support later. Summary of the Utility Model

[0040] Embodiment 1
[0041] As Figures 1-6 shown, a high slope anchor structure includes an anchor rod 1 anchored on the slope surface, and an anchoring mechanism 2 is assembled and connected to the rear end of the anchor rod 1.
[0042] Specifically, when the anchor rod 1 is driven into the slope, the anchoring mechanism 2 is anchored in the slope (near the slope surface).
[0043] Specifically, the anchoring mechanism 2 includes an annular anchor seat 21 slidably connected to the anchor rod 1, and the annular anchor seat 21 is clamped to the anchor rod 1 through a strip structure.
[0044] Specifically, the strip structure includes a number of latching tongue strips 211 welded to the outer side wall of the annular anchor seat 21; correspondingly, a number of pairs of strips 11 (each pair of strips has a length of 5 cm and a height of 2.5 cm) adapted to the latching tongue strips 211 are welded to the outer side wall of the anchor rod 1, and the latching tongue strips 211 are limited in the slot between the strips 11. Specifically, there is a gap between each pair of strips 11.
[0045] During the process of driving the anchor rod 1, the anchoring mechanism 2 retreats from the anchor rod 1. After the anchor rod 1 is driven in, the anchoring mechanism 2 is slid onto the anchor rod 1 and pushed along the anchor rod 1 until the latching tongue strips 211 are caught in the slot between the strips (since the position of the strips is close to the slope surface, during the construction process, after the anchor rod 1 is driven in, a buried hole with a certain width is excavated on the slope surface to facilitate the subsequent pouring of concrete to bury the anchoring mechanism 2 into the concrete filling layer).
[0046] Meanwhile, a number of reinforcing bar structures are fixedly connected to the outer side wall of the annular anchor seat 21. The reinforcing bar structure includes a reinforcing bar seat 22 fixedly connected to the annular anchor seat 21, and a number of hooked reinforcing bar hooks are fixedly connected to the reinforcing bar seat 22.
[0047] Specifically, two hooked reinforcing bar hooks are fixedly connected to the reinforcing bar seat 22, namely the first reinforcing bar hook 221 and the second reinforcing bar hook 222; the hooked directions of the first reinforcing bar hook 221 and the second reinforcing bar hook 222 are opposite. The reinforcing bar seat 22 is a steel bar column welded to the annular anchor seat 21. When the annular anchor seat 21 - the reinforcing bar seat 22 - the first reinforcing bar hook 221 and the second reinforcing bar hook 222 are pushed into the buried hole opened on the slope surface, at this time, the latching tongue strips 211 are caught in the slot between the strips. By this way, the anchoring mechanism 2 is locked with the anchor rod 1. Subsequently, concrete is poured to fill the buried hole. After the reinforcing bars are wrapped in the concrete filling layer, a large grasping force is formed. By this way, the technical defect that it is not easy to anchor the anchor rod 1 after it is driven into the soft soil slope surface and the anchor rod 1 bears the heavy steel bar mesh is solved. By this way, the anchor rod 1 is firmly anchored in the slope. Even in the case of heavy rain, the anchor rod 1 will not loosen, and thus it can effectively support the steel bar mesh of the supporting slope surface.
[0048] Embodiment 2
[0049] As Figures 1-6 shown, on the basis of the structure of Embodiment 1 in this embodiment, in order to squeeze the steel bar mesh hung on the anchor rod 1 to fully contact the slope surface to increase its support effect, the above-mentioned anchoring mechanism 2 further includes an annular pressing plate 23 abutted against the outside of the steel bar mesh, and the annular pressing plate 23 is slidably assembled on the anchor rod 1.
[0050] Specifically, a sliding sleeve A that is integrally formed on the annular abutting plate 23 and slidably connected to the anchor bolt 1; a plurality of alignment sliding guide rods 231 are slidably connected to the annular abutting plate 23. Specifically, the inner ends of the alignment sliding guide rods 231 are welded and fixed to the rib grabbing seat 22. After the through holes on the annular abutting plate 23 penetrate through the alignment sliding guide rods 231, at this time, the annular abutting plate 23 is pushed in until the annular abutting plate 23 touches the steel bar mesh hung on the anchor bolt 1. After the positioning nut 2311 threadedly connected to the alignment sliding guide rod 231 is screwed inward, it is convenient to push the annular abutting plate 23 inward and press it tightly against the steel bar mesh.
[0051] By this method, the abutting and supporting effect of the steel bar mesh on the slope is greatly improved, and by this method, the supporting effect on the high slope is increased, and the defects of its collapse and debris flow are reduced.
[0052] At the same time, in order to improve the supporting effect on the steel bar mesh, 4 hanging rods for supporting on the steel bar mesh are fixedly connected to the inner side wall of the above-mentioned annular abutting plate 23. After the annular abutting plate 23 presses tightly against the steel bar mesh, the hanging rods penetrate into the mesh holes of the steel bar mesh and form a hanging connection. By this method, in cooperation with the anchor bolt 1, the effect and stability of pulling and supporting the steel bar mesh are further increased.
[0053] Embodiment 3
[0054] As Figures 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, in order to facilitate the reaming of the slope with soft soil layer during the process of driving the anchor bolt 1 into the high slope, facilitate the subsequent pouring of concrete filler, and increase the stability of the anchor bolt 1, a reaming drill claw mechanism 3 is hinged to the inner end of the above-mentioned anchor bolt 1, and the reaming drill claw mechanism 3 includes a plurality of reaming drill claws 31. The specific method is as follows: a plurality of hinge holes are opened at the inner end of the anchor bolt 1 (i.e., the drilling part of the anchor bolt 1), and the reaming drill claws 31 are hinged to the hole walls of the hinge holes through fixed pins.
[0055] During the process of driving the anchor bolt 1 into the slope, the reaming drill claws 31 are used for reaming.
[0056] In order to realize the adjustment of the reaming size of the reaming drill claws 31, for example, for a soil layer structure with overly soft soil, by increasing the opening angle of the reaming drill claws 31 to increase the reaming, it is convenient to fill larger concrete fillers subsequently. On the contrary, by reducing the opening angle of the reaming drill claws 31, it is convenient to drill into a soil layer with hard soil.
[0057] Specifically, an adjusting structure for adjusting the opening amplitude of the reaming drill claws 31 is assembled and connected to the inner end of the anchor rod 1. The adjusting structure includes a threaded adjusting rod 33 fixedly connected in the rod cavity of the anchor rod 1. Specifically, an inner fixing seat 32 is fixedly connected in the rod cavity of the anchor rod 1, and the inner end of the threaded adjusting rod 33 is fixedly connected to the inner fixing seat 32. The outer end of the threaded adjusting rod 33 is located outside the rod cavity of the anchor rod 1 (i.e., the outer end of the threaded adjusting rod 33 protrudes from the mouth of the anchor rod 1).
[0058] A threaded seat 341 is threadedly connected to the threaded adjusting rod 33 (the threaded seat 341 is located outside the anchor rod 1). A resisting flange 34 is integrally formed on the outer side wall of the threaded seat 341. The resisting flange 34 abuts against the inner side wall of the reaming drill claws 31. By adjusting the position of the threaded seat 341 on the threaded adjusting rod 33, the position where the resisting flange abuts against the reaming drill claws 31 is adjusted, so as to realize adjusting the opening amplitude of the reaming drill claws 31.
[0059] Specifically, if it is necessary to increase the opening amplitude of the reaming drill claws 31, at this time, the operator turns the threaded seat 341 closer to the anchor rod 1. Since the resisting flange 34 abuts against the inner side wall of the reaming drill claws 31, as the threaded seat 341 approaches the anchor rod 1, the resisting flange 34 continuously pushes the reaming drill claws 31 to open. During the continuous opening process of the reaming drill claws 31, their opening amplitude increases, and the diameter of the reamed hole gradually increases. In this way, the size of the hole drilled by the anchor rod 1 can be changed in an adjustable manner. Furthermore, the size of the hole drilled by the anchor rod 1 can be adjusted according to the construction requirements.
[0060] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
