Abstract

The utility model discloses a vegetation carpet capable of preventing washout of surface soil. The vegetation carpet capable of preventing washout of surface soil comprises an upper mesh, a lower mesh, wherein the upper mesh is arranged on the upper portion of the vegetation carpet and the lower mesh is arranged on the lower portion of the vegetation carpet, an inverted filter which is arranged between the upper mesh and the lower mesh, and a mixture which is arranged between the lower mesh and the inverted filter, wherein the upper mesh, the lower mesh, the inverted filter and the mixture are connected to form a carpet-shaped carpet. The vegetation carpet capable of preventing washout of surface soil is paved on a river side slope and other side slopes which are capable of preventing water erosion, 4 meters per second of water erosion can be resisted, and the vegetation carpet capable of preventing washout of surface soil allows the ecological restoration of the side slope, the water and soil erosion of the side slope is effectively prevented, and the ecological environment is protected and restored.

Description

Prevent from showing the vegetation blanket of native erosion

Technical field

The utility model relates to a kind of vegetation blanket that prevents from showing native erosion.

Background technology

Because the corrosion function of the factors such as waterpower, rainwater, wind-force, can cause the fields such as water conservancy, highway soil-slope soil erosion, vegetation deterioration in addition affect the monolithic stability of side slope, cause riverbed soil body slump, crisis roadbed to wait safely serious consequence.And the hard side slope protection means such as traditional stone masonry, concrete.Though the energy conservation of soil and water, can't be for plant growth create conditions, and side slope can't be carried out again green, uses the normal self purification that has hindered between water and soil in the river course, can not satisfy the requirement of protecting slope ecology.

Summary of the invention

The utility model purpose provides a kind of vegetation blanket that prevents from showing native erosion.

The technical solution of the utility model is: a kind of vegetation blanket that prevents from showing native erosion, it comprises: above upper wire, below lower net, at the loaded filter between upper wire and the lower net and the mixture between lower net and loaded filter, wherein upper wire, lower net, loaded filter, mixture link together and are the blanket shape.

On the basis of technique scheme, further comprise attached technical scheme:

Described upper wire is for being difficult for degradation material, and lower net is easy degradation material.

Described upper wire is composite fiber fabric, and lower net is paper fiber, and loaded filter is nonwoven.

Described mixture comprises vegetable seeds, slow release fertilizer, soil conditioner at least.

The strain footpath of the aperture of the mesh of upper wire and non-woven fabric back filtering layer during all greater than plant seed germination.

Described upper wire, lower net, loaded filter three are connected to the glue bonding connection.

Its thickness is 0.5～3cm, and length is 2～50m, and width is 1～3m.

The utility model advantage is:

The utility model is layed on the side slope of Channel slope and the erosion of other water resistants stream, and the current erosion that can resist 4m/s allows side slope to recover ecological simultaneously, effectively prevents soil erosion of side slope, protection and Revegetation of Eco-environment.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is internal construction schematic diagram of the present utility model;

Fig. 2 is that the utility model is applied to the mounting structure figure on the side slope.

The specific embodiment

Embodiment: at first with reference to shown in Figure 1, the utility model provides a kind of specific embodiment that prevents from showing the vegetation blanket of native erosion, it comprises: above upper wire 10, below lower net 20, at the loaded filter 30 between upper wire 10 and the lower net 20 and the mixture 40 between lower net 20 and loaded filter 30, wherein upper wire 10, lower net 20, loaded filter 30, mixture 40 4 link together and are the blanket shape.Thickness of the present utility model is 0.5～3cm, and length is 2～50m, and width is 1～3m.Vegetation blanket of the present utility model is an integral body.

Upper wire 10 is preferably high-intensity composite fiber fabric for being difficult for degradation material, is formed by the machinery braiding.Upper wire 10 mainly bears the fluid force that comes from the outside, and has guaranteed the erosion-resisting characteristics at grass seeds germination and later stage.

Lower net 20 is easy degradation material, is preferably paper fiber, is used for fixedly grass seeds, prevents that grass seeds is unrestrained.

Loaded filter 30 is filtration material, and material is nonwoven.It mainly plays reverse filter effect, when running into current scour, prevents the loss of soil, grass seeds and fertilizer.

Mixture 40 comprises vegetable seeds, slow release fertilizer, soil conditioner at least.Vegetable seeds select the grass seeds that carries out proportioning according to local climate.

Strain footpath when further, the aperture of the mesh of upper wire 10 and loaded filter 30 is all greater than plant seed germination.

Further, upper wire 10, lower net 20, loaded filter 30 threes are connected to the glue bonding connection, also can adopt other connected modes, as make or the snapping mode.

As shown in Figure 2, during practical application, the vegetation blanket 1 that will be formed by the bonding upper wire 10 of glue, lower net 20, loaded filter 30, the mixture 40 that formed by plant species, slow release fertilizer and soil conditioner, be layed on the side slope 3 that needs protection, by the barbed staple 4 of tool, L shaped nail 5, connecting filament 6 and bear down on one or the fabric pieces 7 of presser feet is fixed on vegetation blanket 1 on the side slope 3, other direct overburden soil 8 on the fabric pieces 7 of bearing down on one, the fabric pieces 7 of presser feet then is pressed in spats 9 times, reaches water resistant stream erosion and multiple green effect.Push up thus continuous vegetation blanket 1 structure of toe from the slope, and the end is fixed, to realize the opposing to current.

Certainly above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with this top technology can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the Spirit Essence of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
