Highway slope protection ecological carpet preparation method

Abstract

The invention discloses a highway slope protection ecological carpet preparation method. The preparation method comprises the following steps: A, utilizing polypropylene (PP) fibers and waste natural fibers as raw materials, adding other fibers, adopting an opener to respectively open the PP fibers, the waste natural fibers and other fibers, using a mixing cotton machine to mix after the opening, then adopting a carding machine for carding, and uniformly distributing the PP fibers, the waste natural fibers and other fibers; and B, utilizing a lapping machine to carry out cross lapping on the carded fibers so as to form a fibrous net, and carrying out post-processing on the fibrous net so as to form a highway slope protection ecological carpet. The method has the advantages that the preparation method is simple, the prepared ecological carpet can ensure the safety of highways and vehicles, and the protection cost of a hard material is lowered.

Description

technical field [0001] The invention relates to a preparation method of an ecological blanket for road slope protection. Background technique [0002] In recent years, my country's expressway construction has developed rapidly, but constructions such as splitting mountains, digging soil, filling, and building bridges will destroy terrain, landforms, and vegetation, resulting in serious soil erosion on slopes. In order to maintain the slope, the traditional slope reinforcement method is to add steel bars with cement. This method is very effective in reducing the instability and erosion of the slope in the initial stage of construction, but as time goes by, the rocks weather, the concrete ages, and the steel bars corrode. , the strength of the slope decreases, the reinforcement effect becomes worse and worse, and the management and operation cost of the expressway increases. At the same time, replacing ecological vegetation with concrete and steel bars will destroy the microc...
