Description

TECHNICAL FIELD

[0002] As an ecological engineering measure, the ecological blanket is widely used in the falling zone area around the reservoir, lake, river and other water areas. The falling zone refers to the falling zone area between the highest water level line during the water rising period and the lowest water level line during the water falling period formed by the water level rising and falling of the river and lake, which is a special seasonal aquatic-terrestrial ecotone ecosystem. The ecological blanket is applied in this environment, which can solve the soil erosion problem caused by the periodic change of water level, promote plant growth and improve the ecological environment.

[0003] The patent scheme with the publication number CN213836683U discloses an anti-scouring blanket for ecological protection of the falling zone slope, which is provided with a buckle fiber surface and a buckle hook surface at both ends of the mesh cloth, and a plurality of U-shaped nails are arranged on the front and back sides of the mesh cloth, so that the size of the anti-scouring pad can be conveniently controlled, the anti-scouring pad only needs to be connected and fastened in the soil by the U-shaped nails without cutting, and the anti-scouring pad is convenient for the staff to carry and lay. However, in actual engineering application, for a large-area falling zone protection or vegetation restoration project, when the ecological blanket is laid, not only is there a requirement for the laying area, but also the adjacent ecological blankets often need to be overlapped to avoid gaps between the ecological blankets, which may become the starting point of soil erosion, leading to soil erosion and affecting the protection effect; and the continuous growth of plant roots is also hindered.

[0004] However, the existing protective blanket, although some like the aforementioned patent scheme, is provided with a connecting structure to combine the anti-scouring blanket, can conveniently adjust the size of the blanket body and meet the laying area requirement, but cannot meet the overlapping requirement.

[0026] The connector is located at the edge of the vegetation body 2. The connector includes a positioning nail 1; the positioning nail 1 is an anchor nail or a plant nail. In this embodiment, conventional long anchor nails are used, which have a better anchoring effect and can effectively prevent the vegetation body 2 from shifting. Specifically, the positioning nail 1 is set along the four sides of the vegetation body 2 to fully fix the vegetation body 2 to the drawdown zone slope and prevent displacement.

[0027] The vegetation body 2 comprises a substrate layer 3, a vegetation seed layer 4, a reinforcing layer and a cover layer 6. The substrate layer 3 is a square mesh cloth made of degradable material. In the embodiment, an environmentally friendly mesh non-woven fabric or degradable synthetic fiber can be used as the material of the substrate layer 3. The reinforcing layer is a grid 5, the grid of the grid 5 penetrates the vegetation seed layer 4 and is fixedly connected with the bottom of the substrate layer 3. The substrate layer 3 is filled with a substrate 301, and the vegetation seed layer 4 is paved with grass seeds. Specifically, the substrate 301 comprises a composition pressed into a block; the composition is a composition mixed by rice husk, straw, water-retaining agent, adhesive, compound fertilizer, hemp fiber and soil. The substrate 301 layer can provide nutrients and support structure required for plant growth, and ensure that the ecological blanket has good soil fixation capacity and erosion resistance. The grass seeds include at least one of wild bluegrass seeds, ox whip grass seeds and Bermuda grass seeds. Such grass seeds have relatively good tolerance to barrenness and waterlogging, and can achieve good ecological restoration effect.

[0028] The grid 5 has a grid bar width of 5-8 cm. The bottom surface of the substrate layer 3 is further provided with a polyester wear-resistant layer, which can further enhance the service life of the ecological blanket. The cover layer 6 is laid on the vegetation seed layer 4 and the reinforcing layer. The cover layer 6 is a coconut fiber mesh.

Specifically, the size markings 9 include three markings, i.e., a 5 cm marking, a 10 cm marking and a 15 cm marking. The origin of the size markings 9 is the left starting point of the lower edge of the substrate layer 3, and the markings are marked along the lower edge of the substrate layer 3.

[0030] The lap positioning mechanism comprises a positioning cylinder 7 provided on the reinforcing layer and a lap column 8 provided at the bottom of the substrate layer 3. The inner diameter of the positioning cylinder 7 matches the outer diameter of the lap column 8. The positioning cylinder 7 penetrates the vegetation seed layer 4, and the bottom surface of the positioning cylinder 7 is flush with the 1 / 2 thickness position of the vegetation seed layer 4. The positioning cylinder 7 and the lap column 8 are separately provided on the left side and the right side of the vegetation body 2. The positioning cylinder 7 is provided with a plurality of positioning cylinders along the direction of the lower edge of the vegetation body 2.

And the setting position of the positioning cylinder 7 is separated from the left edge of the base material layer 3 by 5cm. In this way, the lapping is more reliable.

[0032] In specific applications, when laying the ecological blanket, adjacent ecological blankets can cooperate with each other to realize stable and accurate lapping laying. According to actual engineering requirements, the reference size mark 9 is selected to select the required lapping range, such as selecting 5cm lapping, the lapping column 8 is pressed into the positioning cylinder 7 corresponding to the 5cm mark, and then the reliable lapping of two adjacent ecological blankets at the accurate position is completed. Alternatively, the positioning nail 1 can also be used to reinforce the surrounding of the lapping point, so that the lapping is more stable.

[0033] The ecological blanket for preventing erosion of the falling zone provided in the embodiment can realize stable and accurate lapping laying, and has good ecological restoration effect.
