Description

Technical Field

[0001] This utility model relates to the field of ecological restoration technology, specifically a protective net structure for ecological restoration of bare ground. Background Technology

[0002] The protective netting structure for ground ecological restoration is fixed to the slope using high-strength steel wire rope nets and anchor bolts. It actively intercepts falling rocks and prevents shallow landslides, providing a stable base for vegetation restoration. Its open structure allows plant roots to penetrate, and combined with vegetation concrete spraying technology (which sprays a mixture of soil, cement, grass seeds, etc., onto the slope to form a substrate layer that can support vegetation growth, used for slope ecological restoration and soil and water conservation), it forms a porous water-retaining layer, promoting the mixed growth of shrubs and herbaceous plants, enhancing the natural recovery capacity of the ecosystem. The mesh design optimizes drainage performance, reducing rainwater erosion of the slope, while allowing free exchange of air and moisture, maintaining soil microbial activity.

[0003] Protective nets need to be pre-fixed by inserting anchor rods into the soil. However, since protective nets are generally large and workers need to go around and fix multiple anchor rods one by one, the labor intensity is high and it is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a protective net structure for ecological restoration of bare ground, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective net structure for ecological restoration of exposed ground, comprising a net body and an elastic frame, and further comprising: Several vertical cylinders are disposed inside the elastic frame. The inner wall of each vertical cylinder is slidably connected to a movable block. An anchor rod is bolted to the bottom of each movable block. A support ring is welded to the lower part of the interior of each vertical cylinder. A compression spring is provided at the top of the support ring, and the top of the compression spring is in contact with the bottom of the movable block. A water inlet is provided through the top of the elastic frame, and a sealing cap is threadedly connected to the top of the water inlet.

[0006] Preferably, a ring is fixed inside the water inlet, and a one-way cover is hinged to the bottom of the ring.

[0007] Preferably, the outer diameter of the one-way cover is larger than the inner diameter of the ring.

[0008] Preferably, the surface of the anchor bolt is also welded with several barbs.

[0009] Preferably, the inner diameter of the middle side of the support ring is larger than the outer diameter of the anchor rod.

[0010] Preferably, the interior of the elastic frame is hollow, and the material of the elastic frame is glass fiber reinforced polyurethane composite material.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention involves opening the sealing cover and injecting water into the interior of the elastic frame through the water inlet. The water pressure overcomes the reaction force of the compression spring, causing the movable block to drive the anchor rod downwards and insert it into the soil. This eliminates the need for workers to fix the anchor rods one by one around the entire protective net, saving time and effort. At the same time, the increased weight of the elastic frame after water injection makes the entire protective net less prone to movement, thus improving its stability. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-7As shown, a protective net structure for ecological restoration of exposed ground includes a net body 1 and an elastic frame 2. The net body 1 and the elastic frame 2 are fixed to each other. The elastic frame 2 has a hollow interior and is made of glass fiber reinforced polyurethane composite material. The glass fiber reinforcement significantly improves its tensile strength and puncture resistance, while the polyurethane matrix provides excellent corrosion resistance and a moderate elastic modulus to adapt to slope deformation. Vertical cylinders 3 are installed through the interior of the elastic frame 2, penetrating the bottom surface of the elastic frame 2 and being flush with each other. The inner wall of the vertical cylinders 3 is smooth. A movable block 4 is connected to the vertical cylinder 3. An anchor rod 5 is bolted to the bottom of the movable block 4. A support ring 7 is welded to the lower part of the vertical cylinder 3. The inner diameter of the middle side of the support ring 7 is larger than the outer diameter of the anchor rod 5 so that the anchor rod 5 can pass through. A compression spring 6 is provided at the top of the support ring 7. The top of the compression spring 6 is in contact with the bottom of the movable block 4. Under the action of the compression spring 6, the movable block 4 is always located at the top of the vertical cylinder 3, so that the anchor rod 5 is retracted inside the vertical cylinder 3. A water inlet 9 is provided through the top of the elastic frame 2. A sealing cap 10 is threadedly connected to the top of the water inlet 9.

[0016] During use, the protective net structure is placed on the required slope, and then the sealing cover 10 is opened. Water is injected into the interior of the elastic frame 2 through the water inlet 9 (slope protection is generally installed on the roadside, and water is injected into the interior of the elastic frame 2 by a water truck). A ring 11 is fixed inside the water inlet 9, and a one-way cover 12 is hinged to the bottom of the ring 11. The outer diameter of the one-way cover 12 is larger than the inner diameter of the ring 11. Water can force open the one-way cover 12 and allow it to open downwards. Water passes through the ring 11 and enters the interior of the elastic frame 2. If the water pressure flows in the opposite direction towards the top of the water inlet 9, the one-way cover 12 is pushed closed by the water, preventing water from flowing out of the water inlet 9 in the opposite direction. As the amount of water inside frame 2 increases, the water pressure inside the elastic frame 2 gradually increases, allowing the elastic frame 2 to expand. The water pressure overcomes the upward reaction force exerted on the movable block 4 by the compression spring 6, pushing the movable block 4 and anchor rod 5 downwards. This causes the movable block 4 to drive the anchor rod 5 into the soil. With multiple anchor rods 5 inserted, the protective net structure is fixed to the slope, eliminating the need for workers to fix each anchor rod 5 around the entire protective net, saving time and effort. Afterward, the sealing cover 10 can be closed. The surface of the anchor rod 5 is also welded with several barbs 8, making it difficult to pull out after being inserted into the soil. Furthermore, the increased weight of the elastic frame 2 after being filled with water makes the entire protective net less prone to movement, improving stability.
