Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical materials for filling slope protection and greening, and in particular to a three-dimensional turf reinforced mesh pad. Background Art

[0002] In slope protection projects, vegetation slope protection can not only contain water and consolidate soil, stabilize the slope, but also beautify the ecological environment. It is an important slope protection technology. Vegetation can effectively improve the anti-erosion ability of the base soil, but the protective effect of vegetation weakens with the increase of slope flow velocity. The reinforcement materials in engineering design have a certain influence on the anti-erosion performance of the turf slope protection. Three-dimensional turf reinforced mesh mat grass planting and irrigation ecological slope protection refers to the use of active plants with developed root systems combined with engineering materials such as geosynthetics to establish an active and ecological slope protection system. Through the strong root growth of plants combined with the soil consolidation effect of geosynthetics, a new slope protection technology is used to green and reinforce the slope. Three-dimensional turf reinforced mesh mat materials can greatly improve the anti-slope erosion performance of natural turf, the reinforcement effect of the slope soil, the protective effect of the mesh on the foundation soil, and the lateral continuity between the grass. Greatly improve the stability and anti-scouring ability of the slope, limit the occurrence of shallow surface sliding and uplift of the slope. The three-dimensional turf reinforced mesh mat can significantly improve the anti-erosion performance of natural turf, that is, the greater the flow rate, the more significant the protective advantage of the turf. The three-dimensional turf reinforced mesh mat is planted with grass, and the plants with developed root systems are combined with the three-dimensional reinforced mesh mat to form a growable slope protection. The soil consolidation effect is obvious, and it can withstand the impact of rainwater and effectively prevent surface runoff erosion. In addition, the process is simple, easy to operate, fast in construction, and low in engineering cost. Compared with traditional slope protection projects, it can reduce project investment.

[0003] In the prior art, the utility model patent with announcement number CN213539016U discloses an ecological greening composite mesh mat for slope protection, which includes an upper stretch mesh, a bubble three-dimensional geonet, a lower stretch mesh and a geotextile arranged in sequence from top to bottom, and the overall structure is relatively complex.

[0004] To this end, the present application proposes a three-dimensional turf reinforcement mesh mat whose structure is different from the above-mentioned prior art. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a three-dimensional turf reinforced mesh mat with high strength, good elongation and high resistance to ultraviolet aging, which can better combine with plant turf, improve the erosion resistance of the slope, and improve the project quality and service life.

[0007] The organizational structure of the convex and concave parts is a honeycomb organization or a variable honeycomb organization, and the organizational structure of the long float line part of the warp and weft yarns is a variable double flat organization.

[0008] Furthermore, the cross-sectional area of ​​the warp yarn or the weft yarn is circular, rectangular or square.

[0010] Furthermore, the weave structure of the convex and concave part is based on 1 / 3, 1 / 4, 1 / 5, and 1 / 6 weft twill. In the weave cycle of the convex and concave part, the highest convex point and the lowest concave point adopt double warp or double weft structure to strengthen the protrusion of the convex and concave points and ensure and stabilize the thickness of the mesh pad; while the long floats of the warp and weft yarns are variable double flat weaves, and the long floats of the warp and weft yarns are used as auxiliary structures to increase the porosity of the mesh pad.

[0011] Furthermore, the fabric structure has a thickness of 2 mm to 12 mm and a porosity of 30% to 50%.

The warp yarn and weft yarn of this embodiment are both made of polypropylene raw yarn with a circular cross-section, a linear density of 1020 dtex, and a warp density of 96 strands / 10 cm; the weft yarn uses polypropylene round yarn with a linear density of 1020 dtex and a weft density of 65 strands / 10 cm, and the warp and weft yarns have a yarn diameter of 0.32 mm.

[0017] The warp yarn and the weft yarn work together to form a convex and concave part 100 and a long floating line part 200 of the warp and weft yarns on the fabric surface, and the two are arranged alternately; wherein the structure of the convex and concave part is a honeycomb structure, and the base structure is a 1 / 3 honeycomb structure. Figure 1 In the organization diagram shown, the first and second warp yarns are double warp weaves interwoven with the weft yarns to form a reinforcement convex point 3, which is the highest convex point, and the fifth and sixth warp yarns are double warp weaves interwoven with the weft yarns to form a reinforcement concave point 4, which reinforces the stability of the thickness of the mesh pad to meet the thickness of 5mm. The organization structure of the long float part of the warp and weft yarns is a variable double flat organization, and the warp floats 5 and weft floats 6 serve as auxiliary structures to increase the porosity of the mesh pad.

[0018] The three-dimensional turf reinforced mesh mat of this embodiment has a thickness of 5 mm and a porosity of 45%.

[0019] The utility model is made of polypropylene round wire or flat wire, and takes advantage of its high strength, good elongation, and high anti-ultraviolet aging performance. Through the combination of honeycomb tissue structure and heavy flat fabric tissue, the three-dimensional turf reinforced mesh mat has certain thickness, porosity, water permeability and other properties, which is conducive to plant growth.
