Description

Technical Field

[0001] This utility model relates to the field of ecological grid technology, specifically a bank protection ecological grid. Background Technology

[0002] The flow of water in bodies of water such as rivers, lakes, or oceans has a great impact force, which can lead to soil erosion and scouring in riverbanks and embankments over a long period of time. Therefore, it is necessary to use bank protection engineering to reinforce and protect the riverbank areas, prevent water flow from damaging and losing land and causing bank slope collapse, and avoid serious damage to the surrounding ecological environment and land resources. In addition, important infrastructure and buildings such as roads, bridges, pipelines, and cables are often located in riverbanks and embankments. Bank protection engineering is needed to protect these infrastructure and buildings from the impact of water flow erosion and ensure their safe and stable operation.

[0003] For example, the gabion ecological riverbank protection disclosed in patent publication number CN221855414U includes a first mesh body, a second mesh body, and spiral steel wires. Four first mesh bodies are arranged, enclosing each other along their length. Adjacent first mesh bodies are fixedly connected by spiral steel wires. The two ends of the four enclosing first mesh bodies are fixedly connected to second mesh bodies by spiral steel wires. The first and second mesh bodies are enclosed by spiral steel wires to form a cavity. The gabion mesh, composed of the first and second mesh bodies, allows water and air to pass freely, avoiding obstruction and accumulation of water flow. It has high strength and durability, and can withstand certain loads and impacts. By setting up an ecological layer, a filling layer, and a filter layer in coordination, it can effectively mitigate the impact of gabion ecological riverbank protection on the ecological environment and water quality, achieving coordinated development between the riverbank protection project and the ecological environment.

[0004] While these types of equipment possess high strength and durability, and can withstand certain loads and impacts, they are prone to bulging in the middle of the first net structure when enclosing a long distance due to their own weight or filling pressure. Furthermore, the ecological layer and filling layer of these types of equipment are relatively poor in enhancing ecological functions and maintaining the overall stability of the revetment.

[0005] Therefore, we propose a bank protection ecological grid. Utility Model Content

[0006] One of the technical problems this application aims to solve is to enhance ecological functions and maintain the overall stability of the revetment.

[0007] To address the aforementioned technical problems, this application provides a revetment ecological grid, comprising a first net body and a second net body. The second net body is fixedly connected to both ends of the first net body. The first net body has four sections, which enclose each other along their length to form a accommodating cavity. It also includes support rods, which are installed on the first net body at equal intervals via snap-fit ​​components. The support rods are used to provide rigid support for the first net body. An ecological layer, a filling layer, and a filter layer are arranged sequentially from top to bottom within the accommodating cavity. Ecological bags are disposed on the surface of the ecological layer. Multiple habitat tubes for accommodating small aquatic organisms are dispersed within the filling layer.

[0008] In some embodiments, the snap-fit ​​element is a U-shaped structure with one end closed, and the snap-fit ​​element is made of galvanized steel wire.

[0009] In some embodiments, the cross-sectional area of ​​the support rod is 1.5 times the cross-sectional area of ​​the rod inside the first mesh.

[0010] In some embodiments, the improved planting soil is a mixture of peat moss and well-rotted organic fertilizer in a 2:1 ratio. The ecological bag is a non-woven ecological bag filled with the improved planting soil and arranged along the top edge of the first mesh body. Climbing plants are planted on the surface of the ecological bag.

[0011] In some embodiments, the perch is made of PVC.

[0012] In some embodiments, the inner wall of the perch tube is provided with multiple holes, and the perch tube is filled with broken shells or tree bark fragments.

[0013] In some embodiments, a U-shaped permeable blind pipe is added between the filter layer and the filling layer, and multiple conversion holes are opened in the U-shaped permeable blind pipe. The periphery of the U-shaped permeable blind pipe is wrapped with permeable geotextile.

[0014] This utility model has at least the following beneficial effects: 1. This device binds the support rod to the first net body through the snap-fit ​​component, and then strengthens the first net body in sections through the support rods that are set at equal intervals, thereby improving the deformation resistance of the net body.

[0015] 2. This device can fix the ecological bag to the first net with cable ties. Plant roots can penetrate the ecological bag and enter the filling layer to form a three-dimensional anchor of "vegetation-net-embankment". At the same time, it provides nesting support for birds, enhances the vertical diversity of the ecosystem, and the perches set in the filling layer can provide micro-habitats for small aquatic organisms to avoid the impact of water flow, ensuring that the overall stability of the revetment is maintained while enhancing the ecological function.

[0018] 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.

[0019] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a bank protection ecological grid, including a first net body 1 and a second net body 2, the second net body 2 being fixedly connected to both ends of the first net body 1, the first net body 1 having four parts, which enclose each other along its length to form a receiving cavity 3, and also including: Support rod 4 is installed on the first net body 1 at equal intervals via snap fastener 10, and the support rod 4 is used to provide rigid support for the first net body 1; The containment cavity 3 is provided with an ecological layer 5, a filling layer 6 and a filter layer 7 arranged from top to bottom. The surface of the ecological layer 5 is provided with an ecological bag 8, and multiple habitat tubes 9 for accommodating small aquatic organisms are dispersed in the filling layer 6.

[0020] Example 2: As Figure 3As shown, the snap-fit ​​10 is a U-shaped structure with one end closed. The snap-fit ​​10 is made of galvanized steel wire. The cross-sectional area of ​​the support rod 4 is 1.5 times the cross-sectional area of ​​the inner rod of the first mesh body 1. It should be noted that there are four first mesh bodies 1, which are spliced ​​together by spiral steel wire to meet the needs of the workers to install the first mesh body 1. The first mesh body 1 and the second mesh body 2 are also connected by spiral steel wire (since spiral steel wire is a common existing technology in the market, it is not described in detail in this device). Both the first mesh body 1 and the second mesh body 2 are woven from galvanized steel wire, and the support rod 4 is also made of galvanized steel wire. However, it is connected to the first mesh body 1 by the snap-fit ​​10. The snap-fit ​​10 is a U-shaped structure. When the support rod 4 is put on the first mesh body 1, the free end of the U-shaped structure is screwed together by the clamp, so that the snap-fit ​​10 can fix the support rod 4.

[0021] Example 3: As Figure 2 As shown, the ecological bag 8 is a non-woven ecological bag filled with improved planting soil, and is arranged along the top edge of the first net body 1. Climbing plants are planted on the surface of the ecological bag 8. Polypropylene non-woven ecological bags (size 300mm×200mm, weight ≥80g / ㎡, tensile strength ≥1.5kN / m) are selected. The improved planting soil is mixed with peat moss and decomposed organic fertilizer in a 2:1 ratio, and 5% water-retaining agent (particle size 1-3mm) is added to improve water retention capacity. When filling the bag, the filling amount is controlled to 70%-80% of the bag volume (to avoid overfilling and restricting the growth of plant roots). The bag opening is sealed with a tie (leaving a 10mm margin for ventilation). Then, 10mm wide nylon tie is used to arrange the ecological bag 8 along the top edge of the first net body 1. Each cable tie passes through the mesh of the top of the eco-bag and the first mesh body 1. After tightening both ends of the cable tie, fold it in the opposite direction and use a special tool to press and lock the buckle. Make 3-4 cross-shaped cuts on the surface of the eco-bag with a utility knife. Insert 2-3 vine seedlings (such as kudzu or ivy, seedlings 100-150mm tall) into each cut. After planting, water until the soil is moist (20%-25% moisture content). Water once a week for the first 3 months (dry season) to ensure a seedling survival rate of ≥90%. The perching tube 9 is made of PVC. The inner wall of the perching tube 9 has multiple holes. The perching tube 9 is filled with broken shells or bark fragments. It should be noted that the perching tube is set on the side of the first net body 1 facing the receiving cavity 3. The installation points are marked at intervals of 1-1.5m to ensure that it is located in the middle and lower part of the filling layer 6 (300-500mm from the bottom of the receiving cavity 3 to avoid being covered by surface stones). A "U-shaped fixing clip" is made of galvanized steel wire (the same material as the wire of the net body), which is bent into an open U-shape (fitting the diameter of the perching tube 9). The two ends are passed through the mesh of the first net body 1 and then bent in the opposite direction to lock it. Insert the perching tube 9 into the U-shaped fixing clip (since it is a common existing structure on the market, its structure is not described in this device), ensuring that the tube body is parallel to the surface of the first net body 1 and the pipe opening faces the inside of the river channel. After installing the perching tube 9, fill the receiving cavity 3 with environmentally friendly stones. Microhabitat construction: The holes in the habitat tube 9 and the internal filling material form a multi-level pore structure, providing habitat space for snails, caddisfly larvae, and small crustaceans to avoid the impact of water flow, thereby enhancing benthic biodiversity. Food chain support: The slow degradation of shells and tree bark releases elements such as calcium and carbon, promoting the attachment and growth of algae, providing a food source for aquatic organisms, and forming a basic food chain of "microorganisms-algae-small organisms". Structural reinforcement: The perching tube 9 is rigidly connected to the first net body 1 through a U-shaped clip, which can share the lateral pressure of the filling layer 6 and help enhance the deformation resistance of the net body (especially in soft riverbeds, reducing the net body protrusion caused by local settlement).
