Abstract
Description
Technical Field
[0001] This utility model relates to a fiber bio-mat, and more particularly to a fiber bio-mat structure for use on slopes and banks. Background Technology
[0002] Riverbanks are an important line of defense for intercepting urban non-point source pollution and protecting water bodies. Building ecological riverbanks is an effective way to solve non-point source pollution.
[0003] Fiber bio-mats play a key role in urban non-point source pollution control and are widely used as an ecological slope protection technology. They have the advantages of rapid mass growth of plants, strong plant compatibility, high coverage, prevention of soil erosion, easy formation of small ecosystems, good interception and purification of many pollutants such as SS, N and P, improved slope stability and permeability, low slope protection cost, quick and easy construction, and good landscape effect. They have become a new type of ecological riverbank construction material.
[0004] However, since the fiber bio-mat is laid on a slope with a certain gradient, it is prone to landslides under the weight of the slope itself and other external forces. Therefore, existing technologies use U-shaped nails to fix the fiber bio-mat, a relatively cumbersome process. To solve this problem, a Chinese utility model patent, "A Highway Slope Anti-erosion Bio-mat Retaining Structure" (patent number 202420629423.9), discloses a highway slope anti-erosion bio-mat retaining structure, which uses first and second anchor nails to fix the plant fiber mat to the slope. However, in this structure, because the first barb and conical head are in a fixed, open state, during the process of nailing the anchor nail into the slope, the first barb and conical head impact the soil, creating voids in the soil around the nail hole. Thus, even with barbs, the presence of soil voids leads to insufficient force on the barbs, making it difficult to guarantee a stable fixation effect. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing a fiber bio-mat structure for slopes and banks.
[0006] The fiber bio-mat structure for slope banks described in this utility model includes a bio-mat body and a combined jig for fixing the bio-mat body to the slope bank.

[0008] The anti-detachment sleeve is hammered into the slope and fixed in place, with the tail end of the anti-detachment sleeve penetrating upwards through the biological blanket body.
[0009] The pressure plate is attached to the tail end of the anti-detachment sleeve and presses downward against the upper surface of the bio-mat body.
[0010] The fibre biological blanket structure for slope bank, the biological blanket body includes composite fibre fabric layer, adsorption filling layer, grass seed fertilizer layer and degradable fibre fabric layer which are sequentially stacked from top to bottom.

[0013] The anti-falling rod includes round rod body, and the outer wall of the round rod body is provided with elastic clamping claw extending upward.
[0014] When the anti-falling rod is inserted from the tail end of the outer sleeve under the external force, the front end of the anti-falling rod presses against the elastic top plate to make the elastic top plate compressively move downward.
[0015] When the external force acting on the anti-falling rod disappears, the elastic top plate rebounds to move upward to lift the anti-falling rod upward, the elastic clamping claw is capable of sliding into the guide slot hole, and the tip of the elastic clamping claw is capable of penetrating out of the guide slot hole.

[0025] The present application will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement the present application according to the description.
[0026] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 the fiber biological blanket structure for slope bank according to the present application comprises a biological blanket body 10. The biological blanket body 10 comprises a composite fiber fabric layer 100, an adsorption filling layer 200, a grass seed fertilizer layer 300 and a degradable fiber fabric layer 400 stacked from top to bottom. The composite fiber fabric layer 100 is formed by mixing and needling or weaving cotton fiber or hemp fiber with PLA fiber, far infrared fiber and flame-retardant fiber, which plays a role of supporting and reinforcing the fiber biological blanket, improves the hydraulic impact strength of the slope surface and prevents soil erosion. The adsorption filling layer 200 contains microporous adsorbent such as meerschaum, zeolite or diatom mud, activated carbon and the like, which can improve the ability of the fiber biological blanket to intercept and purify non-point source pollutants. The grass seed fertilizer layer 300 contains rye grass seeds and fertilizer. Rye grass has strong adaptability and belongs to a grass plant with developed root system, which is used for root growth on the slope surface to protect the slope surface. The degradable fiber layer 400 is composed of degradable fiber fabric such as wood pulp fiber fabric. The wood pulp fiber fabric can easily degrade when it comes into contact with water and will not remain in the soil for a long time to affect the environment. At the same time, the degraded wood fiber becomes organic fertilizer, which can increase the fertility of the soil and nourish the grass plant.
