Seed band-net-fiber bundle ecological slope protection structure

Abstract

The invention provides a seed band-net-fiber bundle ecological slope protection structure which comprises an anchor rod, a wire net, seed bands, a fiber bundle and a substrate layer, wherein the wire net is connected with and fixed on the anchor rod; the seed bands are fixed on the weft net of the wire net in parallel; the fiber bundle is vertically fixed on the same weft net; the substrate layercoats the wire net; the fiber bundle and the surface of the wire net form an upward included angle, and the upper end of the fiber bundle is higher than the surface of the substrate layer. The structure can effectively prevent the surface runoff of the substrate layer, improve the water infiltration, ensure the structural stability of the slope surface and the successful plantation of artificial vegetation on the slope surface, realize the reasonable sowing density and sowing depth of plant seeds and reduce the seed dosage, is beneficial to improving the germination ratio and seedling formation ratio of the seeds, has simple and convenient construction, high efficiency and reasonable cost and is mainly used for ecological slope protection projects of various side slopes.

Description

technical field [0001] The invention relates to a protection structure in the field of slope protection, in particular to a "seed belt-network-fiber bundle" ecological slope protection structure. Background technique [0002] In recent years, ecological slope protection has become a key project of ecological environment construction. Although technologies such as hydraulic spraying, three-dimensional net grass planting, geotechnical compartment grass planting, thick-layer substrate spraying and spray-mixed planting have emerged successively, it has been proposed that the anchor rod, added However, there are still many deficiencies in practice. Chinese patent CN2873888 discloses a slope protective greening layer structure, which mainly includes barbed wire, anchor rods fixedly connected with the barbed wire, and a protective greening layer wrapping the barbed wire. Among them, the protective greening layer includes the surface layer containing plant seeds, more cement, straw...

AI Technical Summary

Problems solved by technology

Although it can better prevent rainwater erosion and reduce surface runoff erosion, the alkalinity of the cement has a greater impact on seed germination and root growth, inhibiting the anchoring function of plant roots to the slope, which is not conducive to plant reinforcement of the slope, and high construction cost
