Abstract

The invention relates to anti-ageing vegetative slope-protection geotechnical cloth of a sandwich structure and a preparation method thereof. The geotechnical cloth comprises an upper anti-ageing non-woven cloth layer, a vegetative layer and a lower anti-ageing non-woven cloth layer, wherein the upper and lower anti-ageing non-woven cloth layers and the vegetative layer are fixedly connected intoan integer through needling so as to form the sandwich structure. The preparation method of the geotechnical cloth comprises five steps of fiber web formation, pre-needling, coating, lapping and needling. The anti-ageing vegetative slope-protection geotechnical cloth provided by the invention improves ultraviolet ray resistance and ageing resistance of the material, prolongs the service life of geotechnical cloth, further has relatively good fertility and water retaining capacity, and is beneficial for creating a good plant growth environment.

Description

technical field [0001] The invention relates to an ecological geotextile, which belongs to the technical field of textiles, in particular to an anti-aging plant-growing slope protection geotextile with a sandwich structure and a preparation method thereof. Background technique [0002] In recent years, with the construction of infrastructure such as highways and high-speed railways in my country and the large-scale development of mines, a large number of exposed earth and rock slopes have been formed in these engineering constructions, resulting in vegetation damage and soil erosion, which has a great impact on the ecological environment. big impact. [0003] The traditional slope protection technology mainly uses hard materials such as cement and block stones for slope protection. Although it can reduce soil erosion, the construction period is long, the cost is high, and it is difficult to green the slope after the slope hardens. Although the emerging vegetation slope prote...
