Description

Technical Field

[0001] The utility model relates to the field of green slope protection, in particular to a three-dimensional reinforced vegetation mesh mat. Background Art

[0002] Slope refers to the sloping part of a mountain or earth embankment. Planting green plants on the slope can effectively prevent soil erosion, stabilize the slope structure, and improve the ecological environment. In the construction of transportation projects such as railways, highways, and municipal roads, a large number of fill and cut slopes will be formed. Slope protection forms include green protection, masonry protection, and other forms, among which green protection is becoming more and more mainstream. In the green slope protection project, the protection structure itself is required to have a certain strength, and at the same time be able to resist rain erosion and be conducive to plant growth.

[0003] Due to the large catchment area of ​​the slope, fast water flow, strong scouring ability, lack of soil conditions, nutrient conditions and water conditions for plant growth, it is extremely difficult for plants to survive, resulting in an unstable slope surface, easy slope collapse, and serious soil and water loss. Moreover, since the slope is not covered with plants, it is exposed to the natural environment all year round and is affected by various natural conditions such as wind, rain, sun, and water scouring, making the slope higher and steeper, and the ecological environment of the slope falls into a vicious cycle.

[0004] At present, green protection generally uses three-dimensional geotechnical vegetation nets for slope protection. Due to the low strength of the three-dimensional vegetation net, the applicable slope height is generally below 6m and the slope rate is generally gentler than 1:1.5. When the slope height is high and the slope rate is steep, the three-dimensional vegetation net will be greatly deformed or even damaged by its own weight, substrate, vegetation, etc., making it difficult to achieve the slope protection effect. In addition, the three-dimensional vegetation net is generally fixed to the slope with U-shaped nails. Due to the low strength of the vegetation net itself, a large number of U-shaped nails are required for fixing, which is troublesome to construct and will cause certain damage to the vegetation net during the construction process. Utility Model Content

[0005] In view of the deficiencies of the prior art in the above-mentioned background technology, the purpose of the present utility model is to solve the problems of low strength, large deformation and troublesome construction of the existing three-dimensional vegetation net, which not only improves the strength of the geotechnical vegetation net, but also meets the requirements of soil consolidation and greening.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A three-dimensional reinforced vegetation mat comprises a vegetation mat, wherein the vegetation mat consists of an upper layer and a lower layer, wherein the upper layer comprises a raised geotechnical vegetation net, and the lower layer comprises a three-dimensional geogrid, and the three-dimensional geogrid is laid on a slope surface.

[0008] As a further solution of the utility model, the raised geotechnical vegetation net is connected to the three-way geogrid by binding, winding or welding.

[0009] As a further solution of the utility model, the tensile strength of the three-dimensional geogrid is greater than 5 KN / m.

[0010] As a further solution of the utility model, the raised geotechnical vegetation net is a winding net, a warp knitted net or an extruded net.

[0011] As a further solution of the utility model, the thickness of the raised geotechnical vegetation net is greater than 1CM.

[0012] As a further solution of the utility model, the mesh size of the three-dimensional geogrid is 3-10 times that of the raised geotechnical vegetation net.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model adopts a two-layer structure, and adopts a three-dimensional geogrid and a mesh raised geotechnical vegetation net to combine. The three-dimensional geogrid can greatly improve the strength of the three-dimensional geotechnical vegetation net and avoid the three-dimensional geotechnical vegetation net from causing large deformation. The raised geotechnical vegetation net on the upper layer is connected with the three-dimensional geogrid on the lower layer by binding, winding, welding, etc. to form a composite structure, which not only improves the strength of the geotechnical vegetation net, but also meets the requirements of soil consolidation and greening, provides a force-bearing support structure for the slope protection structure, and solves the problems of low strength and large deformation of the existing three-dimensional net.

[0015] (2) The utility model adopts a composite geotechnical vegetation net, which can reduce the arrangement of U-shaped nails during the construction process, facilitate on-site construction, and can also be used for green protection of slope surfaces with high slope heights and steep slopes.
