Abstract

The invention discloses an ecological geotextile material used for slope protection and capable of effectively preventing water and soil loss, and relates to the technical field of ecological geotextile. The ecological geotextile material comprises a grating surface layer, a first bonding layer, a filter cloth layer, a second bonding layer and a water-permeable enhancement layer from outside to inside, wherein the grating surface layer improves the reinforcement effect of the geotextile material; the filter cloth layer improves the strength, corrosion resistance, ultraviolet resistance, antibiosis, filtration and water permeability of the geotextile material; the strength, the ultraviolet resistance and the corrosion resistance of the geotextile material are further improved by the permeable reinforcing layer; after the ecological geotextile material is used for slope protection, water and soil loss can be effectively prevented for a long time, and the service life is long. The needling shaping device conducts continuous treatment of oil spraying finishing, needling reinforcing and heat shaping on the fiber net to obtain the filter cloth, the passing guide mechanism, the buffering guide mechanism and the needling mechanism are matched, the stability in the guide process is kept, and the strength of the fiber net is improved.

Description

technical field [0001] The invention relates to the technical field of ecological geotextiles, in particular to an ecological geotextile material used for slope protection and effectively preventing soil erosion. Background technique [0002] Geotextiles, also known as geotextiles, are water-permeable geosynthetic materials made of synthetic fibers through needle punching or weaving. Geotextile has excellent functions of filtration, drainage, isolation, reinforcement and protection, and has the characteristics of light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance. [0003] The invention patent of publication number CN112477321A discloses a geotextile, preparation method and application. The geotextile includes a reinforcement layer and a filter cloth layer connected to the outside of the reinforcement layer. An adhesive layer is provided between the reinforcement layer and the fi...
