Description
Technical Field
[0001] This utility model relates to the field of soil nailing wall construction technology, and in particular to an anchoring steel bar for soil nailing wall support. Background Technology
[0002] In the field of civil engineering, soil nailing wall support technology is a widely used support method in projects such as slope stabilization and foundation pit excavation. This technology involves drilling holes on the slope surface of an earthwork slope and then inserting anchor steel bars into the holes. The friction and adhesion between the steel bars and the surrounding soil are used to enhance the shear strength and overall stability of the soil. Alternatively, concrete can be poured into the holes at the same time to improve the stability of the soil. However, traditional anchor steel bar designs often have problems such as complex installation and poor anchoring effect. Especially under complex geological conditions, its support effect is often difficult to achieve the expected results.
[0003] To address the problems inherent in traditional anchored steel bar designs, researchers have been dedicated to developing novel anchored steel bar structures to improve their support effectiveness and construction efficiency. One important direction for improvement is to increase the connection strength between the anchored steel bar and the soil, preventing the steel bar from loosening or being pulled out of the soil. This typically requires designing a mechanism that can effectively lock the steel bar and enhance its connection with the soil.
[0004] Based on this, the applicant proposed an anchoring steel bar for soil nailing wall support to solve the above technical problems. Utility Model Content
[0005] This utility model addresses the shortcomings of existing technologies by providing an anchoring steel bar for soil nailing wall support, thereby solving the aforementioned technical problems.
[0006] This utility model is solved by the following technical solution:
[0007] An anchoring steel bar for soil nailing wall support includes an anchoring steel bar body, one end of which is rotatably provided with a reverse-clamping steel bar, and a ring-shaped steel plate is slidably provided on the anchoring steel bar body. The ring-shaped steel plate corresponds to the reverse-clamping steel bar, and the ring-shaped steel plate moves towards the reverse-clamping steel bar to cause the reverse-clamping steel bar to rotate open until it cooperates with the ring-shaped steel plate to limit its movement and prevent the reverse-clamping steel bar from rotating in the opposite direction.
[0008] Preferably, the anchoring steel bar body is provided with a plurality of reverse-clamping steel bars, which are uniformly arranged in the circumferential direction around the axis of the anchoring steel bar body.
[0009] Preferably, there are four reverse reinforcing bars, which are arranged at 90° intervals around the axis of the anchoring reinforcing bar body in the circumferential direction.
[0010] Preferably, the end of the anchoring steel bar body is provided with a connecting steel plate, and the reverse-clamped steel bar is rotatably connected to the connecting steel plate.
[0011] Preferably, the connecting steel plate is provided with a shaft hole, and the end of the reverse reinforcing bar is provided with a rotating shaft, and the shaft hole is adapted to the rotating shaft.
[0012] Preferably, the reverse reinforcing bar is provided with a ring groove, and the ring plate is provided with a snap-fit part at one end near the reverse reinforcing bar, the snap-fit part being adapted to the ring groove.
[0013] Preferably, after the slope surface of the earthwork slope is drilled with a mechanical drill to set the channel, one end of the anchoring steel bar body with the reverse buckle is inserted into the end of the channel. When the ring buckle steel plate moves towards the reverse buckle and the snap-fit part snaps into the ring buckle groove, the reverse buckle rotates and opens and inserts into the soil.
[0014] Preferably, the diameter of the anchoring steel bar is 28mm.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. Enhanced connection strength and stability: This utility model forms an effective locking mechanism by setting a rotatable reverse-clamping bar on the anchoring bar body and cooperating with a slidingly set ring-shaped steel plate. When the ring-shaped steel plate moves towards the reverse-clamping bar and engages, the reverse-clamping bar can rotate open and firmly insert into the soil, which significantly enhances the connection strength and overall stability between the anchoring bar and the soil, and effectively prevents the bar from loosening or being pulled out in the soil.
[0017] 2. Simplified installation process and improved efficiency: Compared with traditional anchoring steel bars, the structure of this utility model is simpler and easier to operate. The rotating design of the reverse-clamped steel bar and the sliding setting of the ring-clamped steel plate make the installation process more flexible and convenient, reducing construction difficulty and time costs, and improving construction efficiency.
[0018] 3. Adaptability to complex geological conditions: By optimizing the number and layout of the reverse-clamped steel bars, the anchored steel bar structure of this utility model can better adapt to the support needs under different geological conditions. Especially under complex geological conditions, this design can provide a more reliable support effect and ensure the safety and stability of the project.
[0019] 4. Improved support effect: By pouring concrete into the duct and working together with the anchoring steel bars, the stability of the soil can be further improved. The anchoring steel bar structure in this utility model has a good locking mechanism and a tight connection with the soil, which allows the concrete to work better with the steel bars, thereby enhancing the overall support effect.

[0029] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1:
[0030] like Figures 1 to 4As shown, this utility model discloses an anchoring steel bar for soil nailing wall support, comprising an anchoring steel bar body 1 with a diameter of 28mm. One end of the anchoring steel bar body 1 is rotatably provided with a reverse-clamping steel bar 3. A ring-shaped steel plate 4 is also slidably provided on the anchoring steel bar body 1. The ring-shaped steel plate 4 corresponds to the reverse-clamping steel bar 3. The ring-shaped steel plate 4 moves towards the reverse-clamping steel bar 3 to cause the reverse-clamping steel bar 3 to rotate open until it cooperates with the ring-shaped steel plate 4 to limit its movement and prevent the reverse-clamping steel bar 3 from rotating in the opposite direction.
[0031] The anchoring steel bar body 1 is provided with a plurality of reverse-clamping steel bars 3. The reverse-clamping steel bars 3 are evenly arranged around the axis of the anchoring steel bar body 1 in the circumferential direction. In one embodiment, there are a total of 4 reverse-clamping steel bars 3, which are arranged at 90° intervals around the axis of the anchoring steel bar body 1 in the circumferential direction.
[0032] The end of the anchoring steel bar body 1 is provided with a connecting steel plate 2, the connecting steel plate 2 is provided with a shaft hole, the end of the reverse-clamping steel bar 3 is provided with a rotating shaft, the shaft hole is adapted to the rotating shaft, so that the reverse-clamping steel bar 3 is rotatably connected to the connecting steel plate 2.
[0033] The reverse reinforcing bar 3 is provided with a ring groove 31, and the ring plate 4 is provided with a snap-fit part 41 at one end near the reverse reinforcing bar 3. The snap-fit part 41 is adapted to the ring groove 31. After the slope surface of the earthwork slope is drilled with a channel, the end of the anchoring reinforcing bar body 1 with the reverse reinforcing bar 3 is inserted into the end of the channel. When the ring plate 4 moves towards the reverse reinforcing bar 3 and the snap-fit part 41 snaps and limits the position with the ring groove 31, the reverse reinforcing bar 3 rotates open and inserts into the soil.
[0034] like Figures 5 to 7 As shown, in practical use, the anchoring steel bar of this utility model for soil nailing wall support first requires mechanical drilling of the slope surface to form a channel for installation. Then, the end of the anchoring steel bar body 1 with the reverse-clamping steel bar 3 is inserted into the end of the channel. In the initial state, the reverse-clamping steel bar 3 is in a closed state, and the ring steel plate 4 is located between the outer end of the reverse-clamping steel bar 3 and the anchoring steel bar body 1, so that the ring steel plate 4 can slide smoothly to rotate the reverse-clamping steel bar 3. To ensure this relative position, a limiting device for the ring steel plate 4 can be set on the anchoring steel bar body 1, for example, a groove of fixed length can be set so that when the ring steel plate 4 slides to the end of the groove, it is exactly in the above-mentioned relative position. Then, the ring steel plate 4 is moved towards the reverse-clamping steel bar 3 so that the snap-fit part 41 snaps and limits the snap-fit part with the ring groove 31. At this time, the reverse-clamping steel bar 3 rotates and opens and inserts into the soil. Finally, concrete is poured into the channel and concrete is set on the slope surface to form a whole, ensuring the overall stability of the earthwork slope.
[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
