Description

Technical Field

[0001] This utility model relates to the field of slope protection netting technology, and in particular to a slope protection netting. Background Technology

[0002] Soil and water conservation slope protection netting is a flexible ecological protection technology developed to address the low ecological benefits and limited soil and water conservation capabilities of traditional rigid slope protection structures. Its core principle is to achieve soil stabilization and ecological reconstruction on slopes through the synergistic effect of a three-dimensional mesh structure and vegetation restoration measures. This technology is mainly applied to easily eroded areas such as highway slopes, mine restoration, riverbank embankments, and exposed mountain slopes. The netting layer intercepts rainwater runoff and slows its flow velocity, effectively inhibiting raindrop splash erosion and surface erosion. Simultaneously, the netting structure is filled with planting soil, providing germination space for herbaceous and shrub seeds and promoting root penetration and soil anchoring, forming a dual protective layer of "mechanical + biological" protection.

[0003] Soil and water conservation slope protection nets are generally installed in conditions where the soil is loose. In such cases, the anchor rods are prone to falling off. To prevent this problem, the anchor rods are usually lengthened for reinforcement. However, setting longer anchor rods will increase the anchoring cost and reduce the installation efficiency of the anchor rods. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a slope protection net that prevents anchor bolts from falling off and is easy to install while reducing usage costs.

[0005] The technical solution of this utility model: a slope protection net, including a vegetation net, and further comprising: Fasteners for securing vegetation netting include short anchors and long anchors. A wooden board is fixedly installed between two adjacent short anchors. The length of the short anchor is less than that of the long anchor. The long anchor corresponds one-to-one with the wooden board and is rotatably connected to the middle of the wooden board. Optionally, a connecting block is fixedly installed on the top of the short anchor rod, and the connecting block has multiple positioning holes. The wooden board is located inside the positioning holes.

[0006] Optionally, the wooden board is provided with multiple connecting holes, and connecting ropes are tied in the connecting holes. The other end of the connecting ropes is fixedly connected to the vegetation net.

[0007] Optionally, the long anchor bolt is provided with a reinforcement component, which includes multiple fastening rods and a drive component for extending and retracting the fastening rods to the outside of the long anchor bolt.

[0008] Optionally, the long anchor rod has an installation cavity, and the fastening rod is slidably installed inside the installation cavity.

[0009] Optionally, the drive assembly includes a drive plate slidably mounted in the mounting cavity, and multiple connecting rods are rotatably mounted on the drive plate, with each connecting rod corresponding to and rotatably connected to the fastening rod.

[0010] Optionally, the drive assembly further includes a pull rod fixedly mounted on the drive plate, a sealing plate fixedly mounted on the pull rod, a transmission cylinder fixedly mounted in the mounting cavity, the transmission cylinder being slidably connected to and sealed with the sealing plate, a drive box fixedly mounted in the mounting cavity, a sealing plate slidably mounted in the drive box, one end of the drive box being connected to one end of the sealing plate via a delivery pipe, and a drive rod fixedly mounted on the sealing plate.

[0011] Optionally, one side of the drive box, one side of the transmission cylinder, and the delivery pipe are all filled with hydraulic medium, and the cross-sectional area of ​​the drive box is larger than the cross-sectional area of ​​the transmission cylinder.

[0012] In summary, this application includes at least one of the following beneficial technical effects: By connecting multiple short anchor rods with wooden boards, the short anchor rods are integrated into a whole, which effectively improves the tightness between the vegetation net and the slope. By setting a few long anchor rods, the tightness effect is further strengthened, which effectively prevents the vegetation net from falling off. The vegetation net also intercepts slope runoff, reduces water flow velocity, and prevents the surface soil particles from being washed away by rainwater. Attached Figure Description

[0015] The technical solutions of the embodiments of this application 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 application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0016] Example like Figures 1 to 3 As shown, this utility model proposes a slope protection net, including a vegetation net 1. The vegetation net 1 is a multi-layered three-dimensional mesh structure formed by extrusion and stretching of a high-molecular polymer, with a relatively loose appearance. The bottom layer of the vegetation net 1 is a flat base net that fits tightly against the slope surface. The middle layer is a regular or irregular wavy net bag, forming cavities 3-5 cm high. The surface layer is a permeable covering layer. The vegetation net 1 intercepts slope runoff, reduces water flow velocity, and prevents surface soil particles from being washed away by rainwater.

[0017] This embodiment also includes fasteners for securing the vegetation net 1. These fasteners fix the vegetation net 1 to the slope. Furthermore, the fasteners include short anchor rods 2 and long anchor rods 3. A wooden board 202 is fixedly installed between adjacent short anchor rods 2, effectively enhancing the overall integrity between adjacent short anchor rods 2, thereby effectively improving the tensile strength of the short anchor rods 2. This allows multiple short anchor rods 2 to distribute the tensile force, thus preventing the short anchor rods 2 from falling off. The length of the short anchor rod 2 is shorter than that of the long anchor rod 3. The long anchor rod 3 is connected to the wooden board 2. 02 corresponds one-to-one with and rotates to connect with the middle of the wooden board 202. The long anchor rod 3 penetrates into the mud layer and has better stability than the short anchor rod 2. By setting a small number of long anchor rods 3 and connecting them with the wooden board 202, the short anchor rod 2 can be effectively reinforced. When the short anchor rod 2 is subjected to an upward tension, it will exert a downward pressure on the other side of the short anchor rod 2 through the transmission of the wooden board 202, thereby effectively offsetting the tension on the short anchor rod 2 and effectively improving the stability of the vegetation net 1.

[0018] like Figure 2 and Figure 3 As shown, in this embodiment, a connecting block 201 is fixedly installed on the top of the short anchor rod 2. The connecting block 201 is provided with multiple positioning holes. The wooden board 202 is located inside the positioning holes. When installing the wooden board 202, the installation can be completed by inserting the wooden board 202 into the positioning holes and fixing the wooden board 202 and the positioning holes with pins.

[0019] The wooden board 202 has multiple connecting holes 203, and connecting ropes 204 are tied inside the connecting holes 203. The other end of the connecting rope 204 is fixedly connected to the vegetation net 1. By using the connecting rope 204 to fix the vegetation net 1 to the wooden board 202, the number of connection points between the vegetation net 1 and the fasteners can be effectively increased, so that the fasteners are subjected to balanced forces and the problem of easy detachment due to excessive local forces can be prevented.

[0020] like Figure 3 , Figure 4 As shown, in this embodiment, the long anchor rod 3 is provided with a reinforcement component inside. The reinforcement component includes multiple fastening rods 302 and a drive component that drives the fastening rods 302 to extend and retract to the outside of the long anchor rod 3. When the fastening rods 302 extend to the outside of the long anchor rod 3, a barb structure will be formed on the outside of the long anchor rod 3, which can increase the tensile strength of the long anchor rod 3 and make the connection between the long anchor rod 3 and the slope more stable.

[0021] The long anchor rod 3 has an installation cavity 301. The fastening rod 302 is slidably installed inside the installation cavity 301. The drive assembly includes a drive plate 303 slidably installed inside the installation cavity 301. Multiple connecting rods 304 are rotatably installed on the drive plate 303. The connecting rods 304 correspond one-to-one with the fastening rods 302 and are rotatably connected. By lifting the drive plate 303, the connecting rods 304 can be driven to rotate. By rotating the connecting rods 304, the fastening rods 302 can be pushed to move, thereby pushing or pulling the fastening rods 302 out.

[0022] Furthermore, the drive assembly also includes a pull rod 305 fixedly mounted on the drive plate 303, a sealing plate 306 fixedly mounted on the pull rod 305, a transmission cylinder 307 fixedly mounted in the mounting cavity 301, the transmission cylinder 307 being slidably connected to and sealed with the sealing plate 306, a drive box 308 fixedly mounted in the mounting cavity 301, a sealing plate 309 slidably mounted in the drive box 308, one end of the drive box 308 being connected to one end of the sealing plate 306 via a delivery pipe 310, and a sealing plate 309 being fixedly mounted on the sealing plate 309. Hydraulic medium is filled in the drive rod 311, one side of the drive box 308, one side of the transmission cylinder 307, and the delivery pipe 310. When the drive rod 311 is pushed, the sealing plate 309 will move. The moving sealing plate 309 will squeeze the hydraulic medium. The squeezed hydraulic medium will enter the transmission cylinder 307 through the delivery pipe 310 and push the sealing plate 306 to move, which in turn drives the pull rod 305 and the drive plate 303 to move, thereby pushing the fastening rod 302 to move.

[0023] It should be noted that the cross-sectional area of ​​the drive box 308 is larger than that of the transmission cylinder 307, which can effectively amplify the influence of the stroke of the drive rod 311 on the stroke of the drive plate 303, thus amplifying the stroke. As a result, a shorter drive rod 311 can be used to complete the drive, effectively reducing the area and volume occupied by the long anchor rod 3.

[0024] In this embodiment, the vegetation net 1 adopts a multi-layer three-dimensional mesh structure formed by extrusion and stretching of polymer, resulting in a relatively loose appearance. The bottom layer of the vegetation net 1 is a flat base net that adheres tightly to the slope surface. The middle layer consists of regular or irregular wavy netting, forming cavities 3-5 cm high. The surface layer is a permeable cover layer. The vegetation net 1 intercepts slope runoff, reduces water flow velocity, and prevents surface soil particles from being washed away by rainwater. The wooden board 202 can effectively enhance the integrity between two adjacent short anchor rods 2, thereby effectively improving the tensile strength of the short anchor rods 2, allowing multiple short anchor rods 2 to distribute the tensile force, thus preventing the short anchor rods 2 from falling off. The long anchor rods 3 penetrate deep into the mud layer and have better stability than the short anchor rods 2. By setting a small number of long anchor rods 3 and connecting the long anchor rods 3 to the wooden board 202, the short anchor rods 2 can be effectively reinforced. When the fastening rod 302 extends to the outside of the long anchor rod 3, it will form a barb structure on the outside of the long anchor rod 3, which can increase the tensile strength of the long anchor rod 3 and make the connection between the long anchor rod 3 and the slope more stable.
