Description

Technical Field

[0001] This utility model relates to the field of ecological slope protection technology, specifically to a plant fiber cage net slope protection system. Background Technology

[0002] Traditional slope protection methods rely heavily on materials such as concrete, stones, and plastic geocells. While these provide some protection, they damage the ecological environment and hinder vegetation restoration and soil and water conservation. In recent years, the large-scale use of plastic geocells in ecological slope protection has been particularly problematic. Their non-degradability and the large-scale entry of plastic microparticles into the soil and water have caused significant environmental damage, severely impacting the Earth's ecosystem. There is a need for a natural and ecological slope protection material solution that can stabilize slopes, promote plant growth, and minimize environmental impact. Utility Model Content

[0003] This utility model provides a plant fiber cage net slope protection system. By comprehensively utilizing plant fibers and natural ecological materials, it uses a continuous three-dimensional cage net, a combined plant community, vegetation enhancement and water retention structure, combined with the anchoring method of plants to achieve slope stability, prevent soil erosion, and provide a suitable environment for plant growth. This achieves multiple goals of ecological restoration, slope protection and slope utilization, and enables intelligent monitoring and management.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A plant fiber cage net slope protection system includes a top net and a bottom net, with a vertical net structure between the top net and the bottom net. The top net, bottom net, and vertical net structure form at least one cage net cell. The top net, bottom net, and vertical net structure are all plant fiber nets, and the mesh size of the vertical net structure is smaller than that of the top net and the bottom net.

[0006] Furthermore, the mesh diameter of the top and bottom meshes is greater than 20mm, while the mesh diameter of the vertical mesh structure is less than 15mm.

[0007] Furthermore, the top mesh and the vertical mesh structure are integrally formed by weaving, or the connection between the two is fixedly connected by binding, sewing, bonding, or clamping.

[0008] Furthermore, the bottom mesh and the vertical mesh structure are integrally formed by weaving, or the connection between the two is fixedly connected by binding, sewing, bonding, or clamping.

[0009] Furthermore, the top net, bottom net, or vertical net structure is provided with a seed layer.

[0010] Furthermore, the top net, bottom net, or vertical net structure is provided with a nutrient layer.

[0011] Furthermore, the top mesh, bottom mesh, or vertical mesh structure is provided with a water-locking layer.

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] like Figure 1 As shown, a plant fiber cage mesh slope protection system includes a top mesh 1 and a bottom mesh 2, with a vertical mesh structure 3 between the top mesh 1 and the bottom mesh 2. The top mesh 1, bottom mesh 2, and vertical mesh structure 3 enclose at least one cage mesh chamber 4. This utility model does not specifically limit the shape of a single cage mesh chamber 4, such as a quadrilateral chamber, a hexagonal chamber, etc. As long as its structure is a three-dimensional mesh structure with internal space enclosed by the top mesh 1, bottom mesh 2, and vertical mesh, the technical solution falls within the protection scope of this utility model. Moreover, the number of cage mesh chambers 4 can be adjusted according to the specific construction situation. This design facilitates subsequent construction. Since the construction area of ​​slope protection is generally very large, if a single cage mesh design is used, the construction cost is very high, and other connecting structures are required between the individual cage meshes, resulting in low overall stability. Therefore, this technology adopts an overall cage mesh design based on the construction area, that is, weaving all the cage chambers into a whole.

[0030] The top net 1, bottom net 2, and vertical net structure 3 are all plant fiber nets. These plant fiber nets are three-dimensional mesh structures formed from natural plant fibers through processing and treatment. The fiber material of the plant fiber net can be plant fibers, plant fiber bundles, or plant fiber ropes, and its materials are derived from natural plants such as cotton, hemp fiber, and bamboo fiber. This technology uses plant fiber nets because, on the one hand, plant fibers do not pollute the soil, and on the other hand, plant fibers have water-absorbing properties, which can lock in some moisture and prolong the soil's moisture content.

[0031] The mesh size of the vertical mesh structure 3 is smaller than that of the top mesh 1 and the bottom mesh 2. Since the cage mesh chamber 4 needs to be filled with soil and contains seeds or plants, the plant roots are ultimately needed to lock the cage mesh chamber 4 to the slope. Based on this design requirement, the mesh size of the bottom mesh 2 needs to allow plant roots to penetrate, while the top mesh 1 needs to allow soil to be filled and the plant's main stem to emerge upwards. Therefore, the mesh sizes of both need to be sufficiently large. Thus, this technology preferably uses mesh sizes greater than 20mm for both the top mesh 1 and the bottom mesh 2. For the cage mesh chamber 4, the vertical mesh structure 3 forms the side mesh. The mesh size of the side mesh should be small. On the one hand, this can lock in the soil, preventing it from being washed away or slipping off by rainwater; on the other hand, increased mesh density means more fibers, resulting in greater water retention and extending the water retention time within the cage mesh chamber 4. Therefore, this technology preferably uses mesh sizes less than 15mm for the vertical mesh structure 3.

[0032] To further improve the water retention effect of vertical mesh structure 3, such as Figure 2 As shown, the vertical mesh structure 3 is provided with a water-retaining area 5. The mesh size of the water-retaining area 5 is smaller than that of the vertical mesh structure 3, so that water cannot pass through the water-retaining area 5. For each cage mesh chamber 4, the area of ​​the water-retaining area 5 does not exceed 1 / 3 of the area of ​​the inner side mesh of the cage mesh chamber 4. For partially inclined revetment scenarios, the revetment structure needs to be inclined and set on the slope surface. Whether it is the rise and fall of the river or the erosion of rainwater, it will take away the nutrients in the soil. Therefore, the best method is to prevent water flow. In this technology, the lower part of the side mesh of the cage mesh chamber 4 is provided with a water-retaining area 5, forming a water storage space in the cage mesh chamber 4. In this way, water will only flow in the upper layer of the cage mesh chamber 4, achieving the purpose of water storage and retention of nutrients and soil.

[0033] The top net 1 and the vertical net structure 3, and the bottom net 2 and the vertical net structure 3, can be integrally formed by weaving, or the connection between the top net 1 and the vertical net structure 3, and the bottom net 2 and the vertical net structure 3, can be fixedly connected by any of the following structures: binding, sewing, bonding, or clamping. Binding refers to connecting two objects or parts together by binding, fixing, or combining, such as rope binding, fiber binding, bandage binding, or tape binding. Sewing refers to penetrating and interweaving two objects or tissues with sutures, needles, or other tools to form a permanent or temporary bond. Bonding refers to joining the surfaces of two or more objects together using adhesives (glue, adhesive), relying on chemical or physical forces to form a strong interface. Clamping refers to pressing and fixing two or more components together using mechanical external force (such as bolts, clamps, buckles, etc.), utilizing friction or physical constraints to achieve the connection, such as buckles, wedges, etc.

[0034] The top net 1, bottom net 2, or vertical net structure 3 are provided with a seed layer 7, a nutrient layer 8, or a water-locking layer 9. One method is to divide the soil within the cage mesh chamber 4 into a seed layer 7, a nutrient layer 8, or a water-locking layer 9, or to spray seeds, nutrient particles, and water-locking particles onto the top net 1, bottom net 2, or vertical net structure 3. This technology does not limit the specific location of the seed layer 7, nutrient layer 8, or water-locking layer 9, but it will loosen the area below the seed layer 7. For example, if a nutrient layer 8 is located below the seed layer 7, the soil in the nutrient layer 8 will be loosely distributed. Alternatively, the soil below the seed layer 7 can be loosened by inserting needles to facilitate the downward extension of the seed and root system. Figure 3 As shown, from top to bottom, the layers are seed layer 7, nutrient layer 8 or water-locking layer 9.

[0035] The seed layer 7 of this technology utilizes the synergistic effects of plant communities and the root characteristics of different forage grasses to form a three-dimensional protective system on the slope, extending from the surface to the deeper layers. For example, the combination of heart-shaped fibrous roots and taproots allows the fibrous roots to improve the stability of the surface soil, while the taproots extend into the deeper soil, increasing the deep anchoring force of the slope. Another example is the combination of deep roots and shallow roots; the shallow roots prevent topsoil erosion, while the deep roots enhance the slope's resistance to landslides. Furthermore, the combination of grasses and leguminous plants allows the grasses to provide a strong root network structure, while the leguminous plants improve soil fertility and enhance community adaptability through nitrogen fixation. The preferred configuration of this technology is as follows: the top layer plants are shallow-rooted / fibrous-rooted, mainly annuals / biennials, including foxtail grass, ryegrass, milkvetch, goosegrass, sheepgrass, wheatgrass, and bermudagrass, etc., whose function is to quickly cover the surface, reduce slope water evaporation and rainwater erosion, and establish a preliminary stable vegetation layer; the middle layer plants are taprooted / fibrous-rooted, mainly perennials, including white clover, alfalfa, saxaul, and awnless bromegrass, etc., whose function is to fix nitrogen, improve the soil, promote the connection between top layer plants and deep layer plants, and enhance soil structure; the deep layer plants are deep-rooted / taprooted, mainly perennials, including licorice and astragalus, etc., whose function is to allow deep roots to penetrate deep into the slope, provide long-term anchoring force, and prevent landslides.

[0036] The vertical mesh structure 3 is provided with an auxiliary sleeve 6 for fitting the anchor bolts, which is used for anchor bolt insertion and can be used for auxiliary positioning of the vertical mesh structure 3. Alternatively, for the technical solution of separate top mesh 1, bottom mesh 2 and vertical mesh structure 3, during construction, the top mesh 1, bottom mesh 2 and vertical mesh structure 3 can be pulled apart and positioned by anchor bolts, and then the connection and fixation between the top mesh 1, bottom mesh 2 and vertical mesh structure 3 can be carried out.

[0037] like Figure 4 As shown, the bottom net 2 is equipped with a humidity sensor 10, a temperature sensor 11, and a displacement sensor 12. The humidity sensor 10, temperature sensor 11, and displacement sensor 12 are all connected to a wireless transmission module 13 to collect temperature, humidity, position, and displacement information inside the cage mesh chamber 4 in real time, so that staff can understand whether soil erosion, landslides, or other situations have occurred.

[0038] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
