Description

Technical Field

[0001] This utility model relates to the field of slope treatment technology, and in particular to a vegetation restoration device for slope treatment. Background Technology

[0002] Vegetation restoration in slope management is an important ecological restoration measure. It not only helps to restore the damaged ecological environment, but also enhances the stability of the slope. By selecting appropriate vegetation restoration methods and implementing precautions, it is possible to effectively restore the damaged ecological environment, improve the stability of the slope, and prevent natural disasters such as soil erosion and landslides.

[0003] Existing vegetation restoration methods involve directly planting vegetation on slopes. However, in the immediate period immediately following slope restoration, when the vegetation is still in its early stages of growth, its root system is not yet fully developed. If the slope is exposed to rain or river water, the soil covering the roots can easily be loosened or even washed away. The vegetation is very susceptible to being knocked down or even washed away by the water flow after the soil loss, resulting in poor slope restoration and failure to achieve the intended vegetation restoration state. Utility Model Content

[0004] The purpose of this utility model is to solve some problems existing in the prior art and to propose a vegetation restoration device for slope treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vegetation restoration device for slope treatment includes multiple planting units, which are laid sequentially on the slope.

[0007] The planting unit includes:

[0008] The skeleton frame is precast by casting reinforced concrete, and anchor holes are reserved during casting. The skeleton frame is laid on the slope.

[0009] The base layer is set within the skeleton frame;

[0010] A protective pad that covers a base layer, the protective pad comprising a thin fiber layer, a filter layer, a composite fiber fabric layer and a fixed mesh that are fixedly connected to each other from bottom to top;

[0011] An anchor, one end of which is limited to the side of the protective pad away from the base layer, and the other end passes through the protective pad and the anchoring hole in sequence.

[0012] Preferably, the base layer includes, from bottom to top, a clay layer, a gravel layer, a soil layer, an organic matter layer, and a vegetation planting layer laid within the frame.

[0013] The thin fiber layer is bonded to the vegetation planting layer.

[0014] Preferably, the mesh size of the solid mesh is 10m*10m and the tensile strength is not less than 0.8kN / m, the composite fiber fabric layer is made of high-strength polyester mechanically woven, the filter layer is made of non-woven fabric, and the thin fiber layer is made of polylactic acid composite fiber.

[0015] Preferably, the anchor includes an anchor rod that can pass through a protective pad and an anchor hole. A pressure plate is fixedly sleeved on the outer side of the anchor rod. A rotating rod is rotatably arranged inside the anchor rod. A gear located inside the anchor rod is fixedly sleeved on the outer wall of the rotating rod. A rack that meshes with the gear is slidably arranged inside the anchor rod.

[0016] Preferably, the anchor rod is internally fixedly connected to a limiting platform, and an I-beam limiting block is slidably disposed below the limiting platform. The rack is fixedly connected to the bottom of the I-beam limiting block, and one end of the rack can penetrate and extend to the outside of the anchor rod.

[0017] Preferably, the top and bottom of the frame are provided with an upper notch and a lower notch, respectively. After the anchor rod is installed, the pressure plate is located in the upper notch and presses the protective pad into the upper notch. The rack is located in the lower notch. The distance between the pressure plate and the rack is equal to the sum of the minimum distance between the upper and lower notches and the thickness of the protective pad.

[0018] Preferably, the anchor rod has a cylindrical structure with a diameter matching the anchor hole, and the bottom end of the anchor rod is conical.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. The base layer is set inside the frame, which protects and blocks the internal base layer, preventing it from being washed away by rainwater. Covering the base layer with a protective pad reduces the impact of rainwater on the base layer, prevents it from being loosened by rainwater, and also prevents rainwater from washing away the base layer from above. This further enhances the vegetation restoration device's ability to resist soil erosion and avoids the problem of poor slope restoration effect caused by vegetation loss.

[0021] 2. The protective mat is composed of a thin fiber layer, a filter layer, a composite fiber fabric layer, and a fixed mesh, which effectively resists water erosion. The protective mat and the frame are connected by anchors. The protective mat covers the vegetation planting layer with appropriate vegetation, protecting the vegetation and ensuring that the vegetation can grow stably even when the root system is not well developed in the early stage. This avoids the problem of poor slope restoration effect caused by vegetation loss, improves the efficiency and effect of slope management, and promotes the sustainable development of the ecological environment through scientific ecological restoration methods, achieving a win-win situation for economic and ecological benefits.

Detailed Implementation

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] like Figure 1-7 As shown, this utility model provides a vegetation restoration device for slope treatment, including multiple planting units 200, which are laid sequentially on the slope 100.

[0033] The planting unit 200 includes a framework frame 300, a base layer 400, a protective mat 500, and anchors 600. The framework frame 300 is precast from reinforced concrete, with anchor holes 301 pre-drilled during casting. The framework frame 300 is laid on the slope 100. The base layer 400 is placed within the framework frame 300, and the protective mat 500 covers the base layer 400. The protective mat 500 includes a thin fiber layer 501, a filter layer 502, a composite fiber fabric layer 503, and a fixing net 504, which are fixedly connected from bottom to top. The thin fiber layer 501 is bonded to the vegetation planting layer 405. The fixing net 504 increases the strength of the protective mat 500 to prevent deformation, and the filter layer 502 prevents soil from seeping upwards onto the protective mat 500, ensuring soil erosion prevention. The thin fiber layer 501 increases the adhesion between the protective mat 500 and the base layer 400. One end of the anchor 600 is limited to the protective pad 500 on the side away from the base layer 400, and the other end passes through the protective pad 500 and anchoring holes 301 and 400 in sequence for anchoring.

[0034] The base layer 400 is set inside the frame 300. The frame 300 can protect and block the inner base layer 400, preventing the base layer 400 from being washed away by rainwater. Furthermore, the protective pad 500 covers the base layer 400, which can reduce the impact of rainwater on the base layer 400, prevent the base layer 400 from being loosened by rainwater, and also prevent rainwater from washing away the base layer 400 from above. This can further improve the vegetation restoration device's ability to resist soil erosion and avoid the problem of poor slope restoration effect caused by vegetation loss.

[0035] The protective mat 500 is composed of a thin fiber layer 501, a filter layer 502, a composite fiber fabric layer 503, and a fixed mesh 504, which effectively resists water erosion. The protective mat 500 is connected to the frame grid by anchors 600. The protective mat 500 covers the vegetation planting layer with appropriate vegetation, protecting the vegetation and ensuring that the vegetation can grow steadily even when the root system is underdeveloped in the early stage. This avoids the problem of poor slope restoration effect caused by vegetation loss, improves the efficiency and effect of slope management, and promotes the sustainable development of the ecological environment through scientific ecological restoration methods, achieving a win-win situation for economic and ecological benefits.

[0036] In this embodiment, the base layer 400 includes, from bottom to top, a clay layer 401, a gravel layer 402, a soil layer 403, an organic matter layer 404, and a vegetation planting layer 405 laid within the framework 300. A protective mat 500 covers the vegetation planting layer 405, and a thin fiber layer 501 adheres to the vegetation planting layer 405. The clay layer 401 increases the adhesion between the base layer 400 and the slope 100, further enhancing the effect of preventing soil erosion. The gravel layer 402 facilitates the drainage of excess water, preventing root rot. The organic matter layer 404 provides more nutrients, increasing the survival rate of the vegetation.

[0037] In this embodiment, the mesh size of the fixed mesh 504 is 10mm*10mm and the tensile strength is not less than 0.8kN / m. The composite fiber fabric layer 503 is made of high-strength polyester mechanically woven. The filter layer 502 is made of non-woven fabric. The thin fiber layer 501 is made of polylactic acid composite fiber. The fixed mesh 504 can resist water flow erosion and has outstanding impact resistance, achieving the effect of stabilizing the structure. The thin fiber layer 501, made of polylactic acid composite fiber, has strong impact resistance and tensile strength, which can fix the plants. It is also biodegradable and can be decomposed into carbon dioxide and water by microorganisms in soil or water, which is pollution-free and harmless.

[0038] In this embodiment, the anchor 600 includes an anchor rod 601, which can pass through the protective pad 500 and the anchor hole 301. A pressure plate 602 is fixedly sleeved on the outside of the anchor rod 601, and the pressure plate 602 is limited on the side of the protective pad 500 away from the base layer 400. A rotating rod 603 is rotatably arranged inside the anchor rod 601. A gear 604 located inside the anchor rod 601 is fixedly sleeved on the outer wall of the rotating rod 603. A rack 605 that meshes with the gear 604 is slidably arranged inside the anchor rod 601. By rotating the rotating rod 603, the gear 604 is rotated, and the gear 604 drives the rack 605 that meshes with it to move out of the anchor rod 601 and insert into the base layer 400.

[0039] In this embodiment, a limiting platform 606 is fixedly connected inside the anchor rod 601. An I-beam limiting block 607 is slidably disposed below the limiting platform 606. A rack 605 is fixedly connected to the bottom of the I-beam limiting block 607. One end of the rack 605 can penetrate through and extend to the outside of the anchor rod 601. The movement of the rack 605 is limited by the cooperation of the I-beam limiting block 607 and the limiting platform 606.

[0040] In this embodiment, the top and bottom of the frame 300 are respectively provided with an upper notch 302 and a lower notch 303. After the anchor rod 601 is installed, the pressure plate 602 is located in the upper notch 302 and presses the protective pad 500 into the upper notch 302. The rack 605 is located in the lower notch 303. The distance between the pressure plate 602 and the rack 605 is equal to the sum of the minimum distance between the upper notch 302 and the lower notch 303 and the thickness of the protective pad 500.

[0041] In this embodiment, the anchor rod 601 has a cylindrical structure with a diameter matching the anchor hole 301, and the bottom end of the anchor rod 601 is conical. The conical shape makes it easier to insert the anchor rod 601 into the base layer.

[0042] How to use and how to work this device:

[0043] First, multiple framework frames 300 are laid along the slope 100. Within each framework frame 300, a clay layer 401, a gravel layer 402, a soil layer 403, an organic matter layer 404, and a vegetation planting layer 405 are laid sequentially. The vegetation planting layer 405 is used to plant appropriate plants. Then, a protective mat 500 is laid within the upper opening 302 and covers the vegetation planting layer 405. Anchor rods 601 are passed through the protective mat 500 and then through the anchor holes 301, causing the pressure plate 602 to press onto the protective mat 500. Next, rotating rod 603 causes gear 604 to rotate. The rotation of gear 604 pushes the meshing rack 605 against the I-beam limiting block 607 and the limiting platform 606. With the downward movement, the rack 605 can be moved out from the anchor rod 601, inserted into the base layer 400 and locked into the lower notch 303 below the frame 300, thereby securing the protective pad 500 to the vegetation planting layer 405. The protective pad 500, composed of a thin fiber layer 501, a filter layer 502, a composite fiber fabric layer 503 and a fixed mesh 504, has the advantages of resisting water erosion, outstanding erosion resistance and excellent tensile strength, thus protecting the vegetation planting layer 405 covered by it. In the case of underdeveloped root systems, the vegetation will not be easily washed away by water flow, avoiding poor slope restoration effect and ensuring the effect of vegetation restoration.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
