Abstract
Description
Technical Field
[0001] This application relates to the field of civil engineering equipment technology, and in particular to a slope anchor rod. Background Technology
[0002] In civil engineering construction, anchor rods are essential for slope protection and retaining wall construction. Also known as anchor bolts, they are a fundamental component of civil engineering support systems. On one hand, they reinforce the surrounding rock of tunnels, allowing the rock to support itself. On the other hand, they are used for the main reinforcement of slopes, tunnels, and dams. As a tension member deeply embedded in the ground, an anchor rod is connected to the engineering structure at one end and extends into the ground at the other. However, in anchoring softer soil layers, which are not as hard as rock layers, the method of using anchor rods after drilling and grouting often results in the anchor rods being pulled out during pre-tension tests, failing to achieve the required pre-tension. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0030] To address the aforementioned problems, this application provides a slope anchor rod. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.
[0031] like Figure 1 , Figure 2 and Figure 3 The slope anchor shown is, when not in use, such as Figure 1As shown, its structure includes: a main rod 1, which is a hollow anchor rod. The main rod 1 has a hollow cavity 11 inside. An inclined barbed cavity 12 is constructed on the rod wall between the hollow cavity 11 and the main rod 1. A barbed opening 14 is constructed at the bottom of the barbed cavity 12. A limiting groove 13 is constructed on the main rod 1 at the barbed opening 14. This application also includes a threaded shaft 2 and barbs 3. One end of the threaded shaft 2 is rotatably provided with a shaft seat 21, and the other end is rotatably provided with a threaded sleeve 22. A threaded shaft seat 23 is threadedly connected to the threaded shaft 2. A hexagonal nut 24 is fixedly provided at one end of the threaded shaft 2. When the hexagonal nut 24 is located at the opening of the hollow cavity 11, the tip of the barb 3 is exactly located at the barbed opening 14.
[0032] In the application, initially, the rotating shaft seat 21 is fixedly disposed at the bottom of the hollow cavity 11, the threaded sleeve 22 is disposed at the other end of the hollow cavity 11 and the threaded shaft 2 is rotatably located in the hollow cavity 11; the top of the barb 3 is configured as a spike and is adhered with a soft adhesive tape, the soft adhesive tape is located in the limiting groove 13, one end of the barb 3 is connected to the threaded rotating shaft seat 23 and is located in the barb cavity 12, and the other end of the barb 3 is located at the barb opening 14.
[0033] When using this application, first connect the threaded shaft seat 23 to the threaded shaft 2 and position it in a suitable position. This position ensures that after the threaded shaft 2 is inserted into the hollow cavity 11, the barb 3 is positioned exactly in the barb cavity 12. Then, install the barb 3 on the threaded shaft seat 23, insert the installed threaded shaft 2 into the hollow cavity 11, and then restrict it within the hollow cavity 11 by the threaded sleeve 22. Rotate the threaded shaft 2 and check whether the tip of the barb 3 can pierce the barb opening 14. Adhere a soft tape to the tip of the pierced barb and place one end of the soft tape in the limiting groove 13. In this way, the positioning and assembly of the anchor rod is completed. In use, the entire anchor rod is driven into the slope or base. After the main rod 1 is fully inserted into the slope or base, the hexagonal nut 24 is turned using a wrench or other means to rotate the entire threaded shaft 2. At this time, because the top of the barb 3 is spiked, it will insert into the base layer or broken soil outside the main rod 1. Moreover, since the barb 3 is embedded in the barb cavity 12, it cannot rotate with the threaded shaft 2. As the threaded shaft 2 rotates, the threaded shaft seat 23 spirals upward on the threaded shaft 2, causing the barb 3 to pierce out from the barb opening 14 and penetrate into the base layer or slope soil. In this way, the original columnar anchor rod is transformed into a barbed state. During the process of pulling out the anchor rod, the barbs can provide resistance to increase the pre-tension and prevent the anchor rod from being pulled out.
[0034] In one embodiment, the threaded sleeve 22 is threadedly connected to the hollow cavity 11 to limit its rotation after the threaded shaft 2 is inserted.
[0035] In one embodiment, the side of the barb cavity 12 near the barb opening 14 is inclined toward the opening of the hollow cavity 11, so that the barb 3 can slide along the inclined side instead of hitting the end face.
[0036] In one embodiment, such as 1, Figure 2 , Figure 4 and Figure 5 The barbs are arranged in five layers on a plane and in five layers on the main body 1, which can provide more preload.
[0037] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
