Abstract
Description
Technical Field
[0001] This utility model relates to the field of slope protection netting technology, specifically a slope protection netting for water conservancy projects. Background Technology
[0002] Slope protection netting is an important protective structure used in water conservancy projects to reinforce and protect slopes (such as riverbanks, reservoirs, and canals) and prevent them from becoming unstable and collapsing due to water erosion, wind and waves, rainwater erosion, and gravity. Three-dimensional vegetation netting is a type of flexible slope protection netting (ecological slope protection netting). It is typically made of multi-layered filamentous mesh of polyethylene (PE) or polypropylene (PP), resembling a thick plastic "lawn." It has a complex three-dimensional spatial structure. After being laid on the slope, soil is filled inside the netting and seeds are sown. The roots of the plants penetrate the mesh and deeply into the soil, tightly intertwining with the netting to form a green composite protective layer with high tensile strength. The netting itself provides protection for the seedlings and acts as reinforcement. It has the advantages of being eco-friendly, quick to construct, low-cost, and highly effective.
[0003] Existing three-dimensional vegetation nets are fixed and reinforced by U-shaped nails during installation. Ordinary U-shaped nails act directly on a few points of the net mat, causing stress concentration around these points. When strong water flow erodes or soil deformation occurs, the net mat may be "torn" or "pulled off" from the nail holes, leading to fixation failure. Based on this, a slope protection net for water conservancy projects is provided. Utility Model Content
[0004] The purpose of this utility model is to provide a slope protection net for water conservancy projects in order to solve the problems mentioned above.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a slope protection net for water conservancy projects, comprising a three-dimensional vegetation net, wherein an installation and reinforcement component is provided on the upper surface of the three-dimensional vegetation net, the installation and reinforcement component being used to provide auxiliary positioning for the installation of U-shaped nails, and at the same time to strengthen the installation strength of the three-dimensional vegetation net; The installation reinforcement components include a rectangular mesh strip and an annular pressure plate; The annular pressure plates are arranged in pairs, and multiple sets are provided. The multiple sets of annular pressure plates are distributed in a matrix and are connected and fixed to each other by rectangular grid strips. The rectangular mesh strip and the annular pressure plate are fixed to the top of the three-dimensional vegetation net. The annular pressure plate is used to provide positioning for the installation of the U-shaped nails. When the U-shaped nails press the annular pressure plate, the rectangular mesh strip presses the three-dimensional vegetation net in the surrounding area.
[0006] As a further improvement of this utility model, reinforcing ribs are fixed between the four sets of adjacent and rectangularly distributed annular pressure plates.
[0007] As a further embodiment of this utility model: a reinforcing cone nail is fixed on the lower surface of the rectangular mesh strip and the reinforcing rib, and multiple reinforcing cone nails are evenly arranged along the trajectory of the rectangular mesh strip and the reinforcing rib.
[0008] As a further improvement of this utility model, the rectangular mesh strip, the annular pressure plate, the reinforcing rib, and the reinforcing cone nail are integrally formed by injection molding.
[0009] As a further improvement of this utility model, the rectangular mesh strip, the annular pressure plate, and the reinforcing ribs are integrally fixedly connected to the three-dimensional vegetation net through an ultrasonic welding process.
[0010] Compared with the prior art, the beneficial effects of this utility model are: By installing reinforcement components, a multi-layered fixation and reinforcement can be formed on the three-dimensional vegetation net: rectangular grid strips and reinforcing bars provide large-area coverage, increasing friction and dispersing stress; the group of reinforcing cone nails provides strong deep mechanical anchoring; U-shaped nails, through ring-shaped pressure plates, firmly lock the rectangular grid strips, reinforcing bars, reinforcing cone nails and three-dimensional vegetation net to the slope surface. In this way, the three-dimensional vegetation net has stronger reliability and durability when dealing with extreme weather, steep slopes and fragile soil. Attached Figure Description

[0013] 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.
[0014] Please see Figures 1-2 In this embodiment of the utility model, a slope protection net for water conservancy projects includes a three-dimensional vegetation net 1. The upper surface of the three-dimensional vegetation net 1 is provided with an installation and reinforcement component 2. The installation and reinforcement component 2 is used to provide auxiliary positioning for the installation of U-shaped nails 3, and at the same time strengthen the installation strength of the three-dimensional vegetation net 1. The installation reinforcement component 2 includes a rectangular mesh strip 201 and an annular pressure plate 202; The annular pressure tablets 202 are arranged in pairs and there are multiple sets. The multiple sets of annular pressure tablets 202 are distributed in a matrix and are connected and fixed to each other by rectangular grid strips 201. The rectangular mesh strip 201 and the annular pressing plate 202 are fixed to the top of the three-dimensional vegetation net 1. The annular pressing plate 202 is used to provide positioning for the installation of the U-shaped nail 3. When the U-shaped nail 3 presses the annular pressing plate 202, the rectangular mesh strip 201 is used to press the three-dimensional vegetation net 1 in the surrounding area. Four sets of adjacent, rectangularly distributed annular pressure plates 202 are fixed with reinforcing ribs 203. A reinforcing cone nail 204 is fixed on the lower surface of the rectangular mesh strip 201 and the reinforcing rib 203. Multiple reinforcing cone nails 204 are evenly arranged along the trajectory of the rectangular mesh strip 201 and the reinforcing rib 203.
[0015] In this embodiment: When laying this three-dimensional vegetation net 1, the U-shaped nail 3 is aligned with a set of annular pressing plates 202 and inserted. Then, the U-shaped nail 3 is hammered into the soil layer by a tool. The three-dimensional vegetation net 1 is fixed by pressing the annular pressing plates 202 with the U-shaped nail 3. At the same time, when all the U-shaped nails 3 are installed, the annular pressing plate 202 forms a downward pressing effect on the three-dimensional vegetation net 1 around the annular pressing plate 202 through the rectangular mesh strip 201 and the reinforcing rib 203; At the same time, during the installation of U-shaped nails 3, tools (such as rollers or small machinery) can be used simultaneously to tap the rectangular mesh strip 201, reinforcing ribs 203, or step on it to make the reinforcing cone nails 204 at the bottom pass through the three-dimensional vegetation net 1 and insert into the soil layer. The combination of these multiple components forms a multi-layered, multi-mechanism, and extremely powerful "super-fixing system": First line of defense (surface cladding): Rectangular mesh strip 201 and reinforcing ribs 203 provide large-area cladding, increasing friction and dispersing stress; The second line of defense (deep anchoring): The reinforced cone nail group 204 provides powerful deep mechanical anchoring, which is the core combat capability of the system; The third line of defense (ultimate locking): The U-shaped nail 3, through the ring pressure plate 202, firmly locks the rectangular mesh strip 201, the reinforcing bar 203, the reinforcing cone nail 204 and the three-dimensional vegetation net 1 to the slope, which is the "safety bolt" of the whole system; This makes the 3D vegetation net 1 more reliable and durable in the face of extreme weather, steep slopes and fragile soil.
[0016] Please refer to this carefully. Figures 1-2The rectangular mesh strip 201, the annular pressure plate 202, the reinforcing rib 203, and the reinforcing cone nail 204 are integrally formed by injection molding. The rectangular mesh strip 201, the annular pressure plate 202, and the reinforcing rib 203 are fixedly connected to the three-dimensional vegetation net 1 by ultrasonic welding.
[0017] In this embodiment: the installation reinforcement component 2 can be integrally molded from a material with high strength, UV resistance, and corrosion resistance, such as high-density polyethylene (HDPE) or polypropylene (PP), and its service life is matched with the three-dimensional vegetation net. The installation and reinforcement component 2 has a simple overall structure, mature production and assembly processes, controllable production costs, and is easy to promote and apply.
[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
