Description

Technical Field

[0001] This utility model relates to the field of surface environmental care technology, and in particular to an integrated ecological restoration blanket. Background Technology

[0002] In river protection projects with gentle longitudinal slopes, lack of boulders, and ecological greening requirements, as well as slope protection projects in soil and water conservation, such soil stabilizing mats or net mats are needed. A representative example of this type of product is the specific structure disclosed in patent number 201610021784.5, entitled "Slope Ecological Protection Vegetation Mat". After this type of product is laid and fixed on the ground, grass seeds and fertilizers are sprinkled upwards, and moisture is maintained by spraying, so as to achieve the rooting and growth of vegetation. It can both cultivate vegetation and stabilize the surface soil.

[0003] The aforementioned soil stabilization netting or mats have drawbacks in use, which can be summarized as follows: 1. The top structure of existing soil stabilization netting or mats uses a jute mesh layer and a metal mesh layer. However, the jute mesh layer uses a cross-shaped flat weave structure, which has low strength and is prone to increasing local gaps under external stress, affecting the stability of soil stabilization; 3. Existing metal mesh layers mostly adopt an integral molding design, which has poor planar ductility and is easily damaged when subjected to external impact.

[0004] In view of the shortcomings of the existing technology, the urgent technical problem to be solved by those skilled in the art is how to design an integrated ecological restoration blanket, improve the overall strength of the blanket by improving the manufacturing structure of the jute mesh layer and the metal mesh layer, and solve the technical problems of low overall strength and poor ductility in the existing technology. Summary of the Invention

[0005] The problem solved by this utility model is to provide an integrated ecological restoration blanket, which improves the strength and stability of the multi-layer structure of the top surface through the reinforcement design of the blanket body.

[0006] To solve the above-mentioned technical problems, the solution of this utility model is described as follows: an integrated ecological restoration blanket, which includes a bottom layer, a jute mesh layer, and a wire mesh layer; the jute mesh layer is disposed above the bottom layer, and the wire mesh layer is disposed above the jute mesh layer.

[0007] The jute mesh layer is woven from warp and weft yarns. The weft yarn is a single strand, and the warp yarn is a double-strand spiral. A weft yarn passes through each spiral hole, and the diameter of the weft yarn is larger than the diameter of the single warp yarn.

[0008] The wire mesh layer is composed of several double-twisted steel wires, and several polygonal holes are formed by winding a single strand of steel wire. Each polygonal hole has at least two steel wires wound around its longitudinal edge.

[0009] The bottom layer is made of polypropylene filament spunbond nonwoven geotextile, with several through holes processed on the fabric surface, the hole spacing being 2.0 to 5.0 cm.

[0010] The steel wire mesh layer is coated with plastic to improve its corrosion resistance and impact resistance.

[0011] The beneficial effects of this utility model are as follows: This utility model sets a jute mesh layer above the bottom layer of polypropylene spunbond nonwoven geotextile material, and a steel wire mesh layer above the jute mesh layer; the jute mesh layer is woven from warp and weft yarns, with the weft yarns being single strands and the warp yarns being double strands spirals, with one weft yarn passing through each spiral hole. This structure effectively improves the surface strength, making it less prone to deformation, highly stable, and less prone to damage. Combined with the steel wire mesh layer formed by longitudinally double-twisted steel wires, it effectively improves the surface strength of the top two layers, making it less prone to deformation, highly stable, and less prone to damage.

Detailed Implementation

[0020] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0021] This embodiment discloses a specific structure of an integrated ecological restoration blanket, such as... Figure 1 , 2 As shown, it includes a bottom layer 1, a jute mesh layer 2, and a wire mesh layer 3; the jute mesh layer 2 is disposed above the bottom layer 1, and the wire mesh layer 3 is disposed above the jute mesh layer 2.

[0022] More specifically, the bottom layer 1 is made of polypropylene filament spunbond nonwoven geotextile, with several through holes 11 processed on the fabric surface. The spacing between the through holes 11 is 2.0 to 5.0 cm. This bottom layer 1 has good air permeability and can be laid flat on the ground surface. The several through holes 11 make it easier for plants to take root on the ground surface through the bottom layer 1, promoting plant growth.

[0023] The improvement of this utility model lies in the improvement of the jute mesh layer 2. In the prior art, the jute mesh layer adopts a flat weave structure. The twisting method of this structure is similar to that of burlap sack weaving. The drawback of this design is that it is impossible to form large pores. When a flat weave structure is used to form large pores, the pores are usually larger than 0.5 square centimeters, which can easily lead to the loss of good density of the mesh surface. Slight force on the outside can cause the pores to increase, and the function of the mesh surface will be completely lost.

[0024] like Figure 4 , 5 As shown, this utility model uses a jute mesh layer woven from warp yarns 22 and weft yarns 21. The weft yarn 21 is a single strand, and the warp yarns 22 are double-stranded spirals. Figure 6 As shown, in this embodiment, the warp yarns 22 are formed by spirally winding warp yarns I 221 and II 222, with a weft yarn 21 passing through each spiral hole 23, and the diameter of the weft yarn 21 is larger than that of a single warp yarn 22. Through this structural design, the density of the jute mesh layer is greatly improved, and its stability is also enhanced. The mesh size can be 0.5 × 1.0 (±0.2) cm, with a smooth surface and uniform mesh size. During use, when a local area is subjected to external impact, the spirally wound warp yarns 22 have good extensibility, which can absorb impact energy through extension, preventing deformation or loss of the mesh structure.

[0025] The improvement of this utility model lies in that: the outer wire mesh layer 3 is composed of several steel wires wound horizontally, such as... Figure 6 , 7 As shown, the wire mesh layer 3 is formed by double-helical twisting of single strands of steel wire to create several polygonal holes. In this embodiment, the holes are hexagonal. The longitudinal edge 31 of each hexagonal hole is formed by winding at least two steel wires. Figure 7The enlarged view shows that the longitudinal side 31 is reinforced by a double-helical twisting of steel wires I 311 and II 312 on the inclined side 32. Furthermore, the outer periphery of the steel wire mesh layer 3 is coated with plastic, meaning that steel wires I 311 and II 312 are plastic-coated steel wires. This design improves the corrosion resistance and impact resistance of the outer layer of the steel wire mesh layer 3. As the outermost protective layer, the steel wire mesh layer 3 absorbs external impacts from hard objects such as stones and bricks through the helical reinforcement structure on the longitudinal side 31. This mitigates the impact damage to the entire steel wire mesh layer 3 and the integrated ecological restoration blanket to a certain extent, improving durability.

[0026] After molding, this utility model can be used to form a locking edge 4 by sewing the multi-layer structure together at the edge, which can facilitate one-piece fixing and laying and prevent the multi-layer structure from loosening and falling off.

[0027] In summary, this utility model uses a jute mesh layer 2 woven from weft yarn 21 and warp yarn 22, and a steel wire mesh layer 3 formed by double-helix twisting of single strands of steel wire to form several polygonal holes; the above structure effectively improves the strength of the two top woven layers, making them less prone to deformation, more stable, and less susceptible to damage.
