Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective netting technology, specifically an optimized structure for anchor-type protective netting. Background Technology
[0002] Anchor-type protective netting is a structure used for slope protection, mainly composed of anchors, protective netting, and connecting devices. It utilizes the anchoring force provided by deeply reinforced prestressed anchor cables. The anchors, typically made of concrete or other robust materials, are firmly set on the slope to provide necessary support and anchoring force. The protective netting covers the slope surface, effectively capturing and blocking the sliding of rocks, soil, and other materials, thus preventing slope collapse and landslides. Simultaneously, the connecting devices securely fix the protective netting to the anchors, ensuring its stability under external forces.
[0003] Patent CN205502028U discloses a slope protection structure, including multiple anchor blocks and a protective net set on the slope, and a connecting device. The connecting device includes a connecting component for fixing the protective net and a fixing component for connecting to the anchor blocks, with the connecting component fixed to the fixing component. Each anchor block is equipped with one connecting device, and the protective net is fixed to the slope surface area between the anchor blocks through multiple connecting devices. This utility model utilizes the anchoring force of deeply reinforced prestressed anchor cables to economically solve the anchoring force required for shallow slope protection nets, and integrates the prestressed anchor cables and the protective net into a whole force-bearing system. The prestress is ubiquitous throughout the deep and surface protection system, achieving comprehensive local stress and overall load-bearing capacity of the deep and surface protection system; effectively preventing slope collapse and landslides, and greatly improving the protection capability against slope disasters.
[0004] Although existing technologies achieve both localized stress distribution and overall load-bearing capacity in deep and surface protection systems through a combination of connecting devices, prestressed anchors, and anchor blocks, certain limitations remain. For example, the longitudinal rods of the connecting device are fixed to the anchor blocks via concrete pouring; however, the anchor blocks are exposed, and in the event of external impact or other unforeseen circumstances, if the concrete cracks or the connecting device is subjected to excessive tensile force, the connecting device may separate from the anchor block. This situation would cause the support ropes connected to the connecting device to lose their anchoring function, resulting in partial failure of the protective net and a reduction in the overall protective effect. In view of the above problems, we propose an optimized anchor block-type protective net structure to enhance the stability of the connecting device, thereby improving the overall safety and reliability of the protective net. Utility Model Content
[0005] The purpose of this utility model is to provide an optimized structure for anchor-type protective nets to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An optimized structure for anchor-type protective netting includes prestressed anchor cables and a protective netting. The prestressed anchor cables serve as the core load-bearing components, penetrating the anchoring area and extending into the anchoring mold. Through tension, they form an integrated load-bearing system with the concrete anchoring mold. Figure 1 , Figure 2 and Figure 3 As shown, a connecting component is provided on the outer wall of the prestressed anchor cable near the front end. The connecting component is used to modularly connect the protective net and the prestressed anchor cable to achieve load transfer. The connecting component includes an annular fixing block welded to the outer wall of the prestressed anchor cable. The annular fixing block serves as the base of the connecting component and is fixed to the prestressed anchor cable by welding to transfer the tension of the support rope. The outer wall of the annular fixing block is provided with four internally threaded fixing tubes arranged in a circular array. The internally threaded fixing tubes are used to cooperate with threaded rods to assemble the connecting component. The internally threaded fixing tubes are threadedly connected to the threaded rods. The outer end of the threaded rods is integrally formed with a connecting rod. The end of the connecting rod away from the threaded rods is provided with a collar. The collar is fixed to the protective net by the support rope, connecting the protective net and the connecting component. Multiple anchors and the protective net form an overall protection for the slope.
[0008] A concrete anchor block is cast on the outer side of the front end of the prestressed anchor cable through an anchor block mold. The anchor block mold is used to define the shape of the concrete anchor block and to reserve clearance holes for the connecting rod to pass through. The annular fixing block and the internally threaded fixing pipe are both located inside the concrete anchor block. The concrete anchor block is used to wrap and fix the prestressed anchor cable and the connecting components, and to provide anchor support for the surface protective net.
[0009] Preferred, such as Figure 2 As shown, the outer wall of the prestressed anchor cable is provided with multiple barbs, all of which are located in the anchoring groove of the slope, and the anchoring groove of the slope is filled with concrete. The barbs are used to embed into the concrete of the anchoring groove to increase frictional resistance and prevent the prestressed anchor cable from slipping.
[0010] Preferred, such as Figure 3 As shown, a positioning plate is provided on the outer wall of the prestressed anchor cable near the opening of the slope anchoring groove. A pouring clearance opening is provided on the outer wall of the positioning plate to prevent the positioning plate from blocking the concrete from flowing into the anchoring groove. The positioning plate is located inside the concrete anchor pier to increase the contact surface between the prestressed anchor cable and the concrete anchor pier.
[0011] Preferred, such as Figure 4As shown, the prestressed anchor cable has multiple first anti-detachment rods arranged in a ring array on its outer wall near the rear side of the annular fixing block. The first anti-detachment rods are used to embed into the concrete anchor block to increase the contact area between the anchor cable and the concrete to prevent detachment. The prestressed anchor cable also has multiple second anti-detachment rods arranged in a ring array on its outer wall near the front side of the annular fixing block. The second anti-detachment rods cooperate with the first anti-detachment rods to form an effective anti-detachment structure.
[0012] Preferred, such as Figure 2 As shown, both the first and second anti-detachment rods are located inside the concrete anchor pier. The double anti-detachment rod design is used to improve the pull-out resistance of the anchor cable in the concrete.
[0013] Preferred, combined Figure 2 and Figure 5 As shown, the anchor mold is a truncated pyramidal structure. The top inclined surface of the anchor mold is provided with a pouring pipe. The input end of the pouring pipe is threaded with a cap. The pouring pipe is used to inject concrete into the anchor mold. After pouring, it can be sealed by the threaded cap.
[0014] The side of the internally threaded fixing tube away from the annular fixing block is fitted against the inner wall of the anchor mold. This fitted design prevents concrete from seeping into the internally threaded fixing tube and affecting the connection function of the threaded rod. The outer side of the anchor mold has four clearance holes, which are connected to the four internally threaded fixing tubes respectively. The connecting rod passes through the clearance holes to prevent the anchor mold from obstructing the assembly of the connecting components. In use, after the concrete in the anchoring groove of the slope has solidified, the anchor mold is placed on the outer side of the front end of the prestressed anchor cable, and the rear opening of the anchor mold is pressed against the slope surface to reduce the amount of concrete seepage. Then, the four threaded rods are passed through the four clearance holes and threadedly connected to the corresponding internally threaded fixing tubes. Finally, concrete is poured into the anchor mold through the pouring pipe. After the concrete solidifies, a concrete anchor is formed. The anchor mold can provide a certain degree of protection for the concrete anchor.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The optimized structure of this anchor-type protective netting combines modular connecting components with concrete anchors, embedding the connection structure between the protective netting and the prestressed anchor cable inside the anchor and connecting it with the prestressed anchor cable, thus preventing the connecting device from detaching due to external impact or concrete cracking.
[0017] 2. The optimized structure of this anchor-type protective net, with concrete anchors protecting the connecting structure and the reinforced combination of barbs, anti-detachment rods and anchor cables, significantly reduces the risk of component aging due to mechanical damage. The overall structure has high weather resistance and fatigue resistance, can be used stably for a long time, and reduces the need for later maintenance. Attached Figure Description

[0026] Please see Figures 1-5 This utility model provides a technical solution:
[0027] An optimized structure for anchor-type protective netting includes prestressed anchor cables 100 and a protective netting. The prestressed anchor cables 100 serve as the core load-bearing component, penetrating the anchoring area and extending into the anchor mold 300. Through tension, they form an integrated load-bearing system with the concrete anchor 400. Figure 1 , Figure 2 and Figure 3 As shown, a connecting component 200 is provided on the outer wall of the prestressed anchor cable 100 near its front end. The connecting component 200 is used to modularly connect the protective net to the prestressed anchor cable 100 to achieve load transfer. The connecting component 200 includes an annular fixing block 210 welded to the outer wall of the prestressed anchor cable 100. The annular fixing block 210 serves as the base of the connecting component 200 and is fixed to the prestressed anchor cable 100 by welding to transfer the tension of the support rope 500. The outer wall of the annular fixing block 210 is provided with four ring-shaped arrays. The internally threaded fixing tubes 220 are arranged in rows. The internally threaded fixing tubes 220 are used to cooperate with the threaded rods 230 to realize the assembly of the connecting component 200. The internally threaded fixing tubes 220 are threadedly connected to the threaded rods 230. The outer end of the threaded rods 230 is integrally formed with a connecting rod 231. The end of the connecting rod 231 away from the threaded rods 230 is provided with a collar 240. The collar 240 is fixed to the protective net by the support rope 500, connecting the protective net to the connecting component 200. Multiple anchors and the protective net form an overall protection for the slope.
[0028] A concrete anchor 400 is cast on the outer side of the front end of the prestressed anchor cable 100 through the anchor pier mold 300. The anchor pier mold 300 is used to define the forming shape of the concrete anchor 400 and to reserve a clearance hole 310 for the connecting rod 231 to pass through. The annular fixing block 210 and the internally threaded fixing pipe 220 are both located inside the concrete anchor 400. The concrete anchor 400 is used to wrap and fix the prestressed anchor cable 100 and the connecting component 200, and to provide anchor support for the surface protective net.
[0029] In this embodiment, as Figure 2 As shown, the outer wall of the prestressed anchor cable 100 is provided with multiple barbs 110. The multiple barbs 110 are all located in the anchoring groove of the slope, and the anchoring groove of the slope is filled with concrete. The barbs 110 are used to embed into the concrete of the anchoring groove to increase the frictional resistance and prevent the prestressed anchor cable 100 from slipping.
[0030] Specifically, such as Figure 3 As shown, a positioning plate 120 is provided on the outer wall of the prestressed anchor cable 100 near the opening of the slope anchoring groove. A pouring clearance opening 121 is provided on the outer wall of the positioning plate 120. The pouring clearance opening 121 is used to prevent the positioning plate 120 from blocking the concrete from flowing into the anchoring groove. The positioning plate 120 is located inside the concrete anchor 400, increasing the contact surface between the prestressed anchor cable 100 and the concrete anchor 400.
[0031] Furthermore, such as Figure 4 As shown, a plurality of first anti-detachment rods 130 are provided on the outer wall of the prestressed anchor cable 100 near the rear side of the annular fixing block 210. The first anti-detachment rods 130 are used to embed into the concrete anchor pier 400 to increase the contact area between the anchor cable and the concrete to prevent detachment. A plurality of second anti-detachment rods 140 are provided on the outer wall of the prestressed anchor cable 100 near the front side of the annular fixing block 210. The second anti-detachment rods 140 cooperate with the first anti-detachment rods 130 to form an effective anti-detachment structure.
[0032] Furthermore, such as Figure 2 As shown, the first anti-detachment rod 130 and the second anti-detachment rod 140 are both located within the concrete anchor pier 400. The double anti-detachment rod design is used to improve the pull-out resistance of the anchor cable in the concrete.
[0033] Furthermore, in combination Figure 2 and Figure 5 As shown, the anchor mold 300 has a truncated quadrangular structure. The top sloping surface of the anchor mold 300 is provided with a pouring pipe 320. The input end of the pouring pipe 320 is threaded with a cap. The pouring pipe 320 is used to inject concrete into the anchor mold 300. After pouring, it can be sealed by the threaded cap.
[0034] The side of the internally threaded fixing pipe 220 away from the annular fixing block 210 is fitted against the inner wall of the anchor mold 300. This fitted design prevents concrete from seeping into the internally threaded fixing pipe 220 and affecting the connection function of the threaded rod 230. Four clearance holes 310 are provided on the outer side of the anchor mold 300, each communicating with one of the four internally threaded fixing pipes 220. The connecting rod 231 passes through the clearance holes 310 to prevent the anchor mold 300 from obstructing the assembly of the connecting component 200. During use, when the concrete in the anchoring groove of the slope... After the soil solidifies, the anchor mold 300 is placed on the outside of the front end of the prestressed anchor cable 100, and the rear opening of the anchor mold 300 is pressed tightly against the slope surface to reduce concrete seepage. Then, four threaded rods 230 are passed through the four clearance holes 310 and threadedly connected to the corresponding internal threaded fixing pipes 220. Finally, concrete is poured into the anchor mold 300 through the pouring pipe 320. After the concrete solidifies, a concrete anchor 400 is formed. The anchor mold 300 can play a certain protective role for the concrete anchor 400.
[0035] In this embodiment of the optimized anchor-type protective net structure, during slope protection construction, firstly, prestressed anchor cables 100 are installed in the prepared slope anchoring groove, and the ends of the prestressed anchor cables 100 are extended to a preset position; then, concrete is poured into the anchoring groove, and the barbs 110 increase the frictional resistance with the concrete; after the concrete in the slope anchoring groove has solidified, the anchor mold 300 is fitted onto the outer side of the front end of the prestressed anchor cable 100, ensuring that the clearance hole 310 of the anchor mold 300 corresponds to the position of the internal threaded fixing pipe 220, and that the side of the internal threaded fixing pipe 220 away from the annular fixing block 210 is attached to the inner wall of the anchor mold 300 to prevent mixing. Concrete is infiltrated, and then the threaded rod 230 is passed through the clearance hole 310 and threadedly connected to the internally threaded fixing pipe 220. The connecting rod 231 and the collar 240 are assembled to the connecting assembly 200 through the fixing action of the threaded rod 230. After that, concrete is injected into the anchor block mold 300 through the pouring pipe 320 to form a concrete anchor block 400 that wraps the prestressed anchor cable 100, the annular fixing block 210, the internally threaded fixing pipe 220, the first anti-detachment rod 130 and the second anti-detachment rod 140. After the concrete anchor block 400 is formed, the protective net is connected to the support rope 500 through the collar 240. Finally, multiple anchor blocks and protective nets constitute an overall protective system.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
