Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation technology, and more specifically, to a novel planting and maintenance net. Background Technology

[0002] Slope greening is an indispensable part of the construction of highways, railways, water conservancy and other projects. Its main purpose is to prevent slopes from being affected by rainwater erosion, weathering and other factors, and to protect the stability of the slopes.

[0003] Currently, the two most common methods of slope greening are vegetation slope protection and engineering slope protection. Although vegetation slope protection has good ecological benefits, the root system of vegetation is loose in the early stages of growth, and its ability to stabilize the soil is poor, making it difficult to play an effective protective role. Engineering slope protection, such as masonry slope protection and shotcrete, has a better protective effect, but it has problems such as a significant heat island effect and the inability to achieve vegetation restoration, resulting in poor ecological benefits.

[0004] Traditional protective fabrics have several shortcomings in the process of planting vegetation on slopes. First, protective fabrics are mostly made of non-woven fabric. Due to their material characteristics, non-woven fabrics are often quite dense and have poor air permeability. When covered on newly sown slopes, they can compress the plant seeds underneath, restricting their growth space and affecting gas exchange and water absorption between the seeds and the soil, thus leading to a low seed germination rate. Second, this type of protective fabric often has poor soil stabilization effects, easily causing rocks or ballast on the slope to move or even slide down, thereby reducing the effectiveness of slope vegetation planting. These are the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art above, and then to propose a new type of planting and maintenance net.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a novel planting and maintenance net, including an upper protective cloth and a protective net. The upper protective cloth covers the top of the protective net. The upper protective cloth is provided with several constraint-reducing zones that accommodate the germination and penetration of seeds, and there is an intermediate gap between adjacent constraint-reducing zones. The protective net is made of multiple plastic filaments interwoven and connected to form several irregular N-sided grids, wherein N≥4. Nodal protrusions are provided at the intersections of the plastic filaments to increase the connection strength at the intersections.

[0007] A further improvement of this invention is that the linear array within the constraint reduction zone has several circular holes or elongated slits.

[0008] A further improvement of this utility model is that a lower protective cloth is provided at the bottom of the upper protective cloth, and the upper protective cloth and the lower protective cloth are joined together by hot-melt stitching at the middle interval, and a rectangular placement cavity is formed between the constraint weakening area and the lower protective cloth.

[0009] A further improvement of this utility model is that the plastic filament and the segment are integrally formed.

[0010] A further improvement of this utility model is that the protective net forms several irregular quadrilateral grids.

[0011] A further improvement of this invention is that both the plastic filaments and the protrusions are made of PP material.

[0012] A further improvement of this invention is that both the plastic filaments and the protrusions are made of PE material.

[0013] A further improvement of this utility model is that a water-retaining layer is added to the lower surface of the upper protective cloth or between the upper and lower protective cloths.

[0014] The beneficial effects of this utility model are as follows: The constraint-reducing zone of this application is designed to accommodate seed germination and penetration. The round holes or elongated slits within the constraint-reducing zone allow for sufficient gas exchange and water absorption between the seeds and the soil during growth, which is beneficial to seed growth and germination. Through the design of the protective net structure and the selection of materials, the strength of the protective net is significantly improved compared to existing technologies, greatly enhancing the geonet's resistance to external forces. In summary, this application combines protective fabric and protective netting, which not only provides sufficient growth space for seeds during slope planting, promoting vegetation recovery and growth, but also effectively prevents soil and rock landslides, ensuring the stability and safety of the slope structure, thereby improving ecological benefits.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0021] like Figures 1-4 As shown, a novel planting and maintenance net includes an upper protective fabric 2 and a protective net 1. The upper protective fabric covers the top of the protective net. The protective net is used for soil stabilization, while the upper protective fabric effectively protects the seeds below, providing insulation and moisture retention. The upper protective fabric 2 is mainly made of polypropylene non-woven fabric, polyethylene woven fabric, or polypropylene woven fabric. These materials have good weather resistance and a certain degree of breathability, while also possessing sufficient strength to meet the needs of slope greening.

[0022] The upper protective fabric 2 is provided with several constraint-reducing zones to accommodate seed germination and penetration. These constraint-reducing zones are designed to reduce pressure on seed growth and improve seed germination rate. An intermediate interval 23 is left between adjacent constraint-reducing zones to ensure the overall structural strength of the upper protective fabric 2.

[0023] Furthermore, the linear array within the constraint reduction zone has several round holes 21 or elongated slits 22. The arrangement of these round holes 21 or elongated slits 22 allows the seeds to fully exchange gases and absorb water with the soil during growth, which is beneficial to seed growth and germination.

[0024] In at least one embodiment, such as Figure 3 As shown, the upper protective fabric 2 has a lower protective fabric 3 at its bottom. The upper protective fabric 2 and the lower protective fabric 3 are joined together by heat fusion stitching at a mid-spacing 23. This connection method ensures the strength between the upper protective fabric 2 and the lower protective fabric 3, and also makes the structure of the entire planting and maintenance net simpler and easier to produce. A rectangular placement cavity is formed between the constraint-reducing area and the lower protective fabric. People can directly pull open the long strip 22 to place the seed packet in the rectangular placement cavity between the upper protective fabric 2 and the lower protective fabric 3. The seed packet is wrapped in glutinous rice paper and contains grass seeds and nutrient soil.

[0025] Furthermore, a water-retaining layer is added to the lower surface of the upper protective fabric 2 or between the upper protective fabric 2 and the lower protective fabric 3. This water-retaining layer contains water-retaining materials or nutrient solutions, such as superabsorbent polymers, sodium alginate, humic acid, etc., which can absorb and store large amounts of water and nutrients, providing a continuous supply of water and nutrients for plant seeds. The addition of the water-retaining layer significantly improves the water and fertilizer retention capacity of the planting and maintenance net, providing a continuous supply of water and nutrients for plant seeds and promoting plant growth and development.

[0026] The solution can be further refined; the water-retaining layer can be designed as a thin layer that fits tightly against the upper protective fabric 2, or it can be fixed to the lower surface of the upper protective fabric 2 by means of sewing, bonding, or other methods.

[0027] In at least one embodiment, the protective net 1 is formed by interlacing multiple plastic filaments 11 to create several irregular N-sided grids 13, where N ≥ 4. N represents the minimum number of sides of the polygon, and N ≥ 4 means that these grids 13 have at least four sides, ensuring structural diversity and stability. Preferably, the protective net forms several irregular quadrilateral grids. The quadrilateral grids can adapt to the external forces generated by rock blocks or ballast on the net body and distribute the external forces evenly to each plastic filament, reducing the breakage of the protective net. At the same time, it provides a certain degree of protection for the upper protective fabric and seeds, making it particularly suitable for engineering fields such as slope protection and roadbed reinforcement.

[0028] In a more detailed design, N can be preferably 5, and the protective net is made of multiple interwoven plastic filaments to form several irregular pentagonal grids.

[0029] Furthermore, protrusions 12 are provided at the intersections of the plastic wires 11 to increase the connection strength at the intersections. These protrusions not only increase the contact area at the intersections, but also effectively disperse the stress acting on the mesh through their unique shape design, significantly improving the overall structural stability and service life. The protrusions 12 connect and reinforce each intersection of the plastic wires 11, making the geonet less prone to damage when facing complex and changing soil environments and external forces.

[0030] In a more detailed design, the plastic filament 11 and the segment 12 are integrally formed by punching holes in a plastic sheet at designed positions using a mold, followed by heating and stretching from different directions. This design simplifies the production process, reduces assembly costs, and ensures a seamless connection between the two components.

[0031] Furthermore, both the plastic filaments 11 and the protrusions 12 are made of PP material. PP (polypropylene) material is lightweight, high-strength, corrosion-resistant, and has good thermal stability, making it very suitable for geonets exposed to outdoor environments for extended periods. In addition to PP material, the plastic filaments 11 and protrusions 12 can also be made of PE material.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
