3D mesh vegetation blanket

Abstract

The invention discloses a 3D mesh vegetation blanket. The 3D mesh vegetation blanket comprises a vegetation blanket body, plant seeds and nutrient soil, wherein the vegetation blanket body comprises asurface layer, a middle layer and a bottom layer; the surface layer and the bottom layer are both of mesh structures, meshes of the surface layer are larger than those of the bottom layer, the mesh structure of the surface layer and the mesh structure of the bottom layer are connected through central wires, and the central wires are located at the middle layer. and the mesh structure of the surface layer, the mesh structure of the bottom layer and the central wires for connecting the mesh structure of the surface layer and the mesh structure of the bottom layer form a funnel-shaped mesh structure with a wide upper part and a narrow lower part. The 3D mesh vegetation blanket is formed through one-time weaving, the manufacturing process is simple, and the cost is reduced. The funnel-shapedmesh structure on the vegetation blanket can effectively stabilize vegetation and accumulate a proper amount of water, so that on one hand, water and soil loss caused by rain wash is avoided, and on the other hand, too fast evaporation of the water in arid climate is avoided.

Description

technical field [0001] The invention relates to a 3D mesh vegetation blanket. Background technique [0002] like Figure 4 Vegetation net slope protection refers to the use of active plants combined with geosynthetic materials and other engineering materials (vegetation blanket / slope protection cloth) to build a protection system with its own growth ability on the slope surface, and to reinforce the slope through the growth of plants. new technology. According to the characteristics of slope topography, soil quality and regional climate, a layer of geosynthetics is covered on the surface of the slope and a variety of plants are planted according to a certain combination and spacing. Through the growth activities of plants, the purpose of strengthening the root system and preventing erosion of stems and leaves can be achieved. After ecological slope protection technology treatment, dense vegetation coverage can be formed on the slope surface, and intertwined root systems can...

Problems solved by technology

And this vegetation blanket has the following defects: 1, the connection between the vegetation layer and the growth matrix layer is not stable enough, the growth matrix layer will produce loss after being washed away by rainwater erosion, and the connection between the plant root system and the growth matrix layer becomes unstable, Eventually lead to the loosening of vegetation; 2. The connection between the growth substrate layer and the cushion layer is not strengthened by the interweaving similar to plant roots, and it is easy to directly separate the growth substrate layer from the cushion layer; 3. The cushion layer is made of degradable materials , laid directly on the green surface, after a period of time, the cushion layer is gradually degraded, and the vegetation blanket will be directly separated from the surface

However, the defects are obvious. Firstly, the materials used for each layer are different, and the material cost is relatively high. In the subsequent steps, each layer must be stitched layer by layer, which increases the manufacturing cost. The water and air permeability between layers is inconsistent, which affects the growth of vegetation roots in different positions
