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...

Embodiment 1

[0019] Embodiment one: the present invention shows a kind of preparation method specific implementation of road slope protection ecological blanket, comprises the following steps: A, with PP fiber and waste and old natural fiber as raw material, other fiber refers to the naturally degradable fiber that length is greater than 23mm, The PP fibers, waste natural fibers and other fibers are respectively opened by an opener, and then mixed by a cotton mixer after opening, and then carded by a carding machine to evenly distribute the PP fibers, waste natural fibers and other fibers; B. The combed fibers are cross-laid with a web-laying machine. After the web-laying is completed, a needle-punching machine is used for pre-punching and reinforcement to form an ecological blanket base material, and then the ecological blanket base material is needled to form a road slope protection ecological blanket. .

Embodiment 2

[0020] Embodiment two: a kind of preparation method of road slope protection ecological blanket, comprises the following steps: A, with PP fiber and waste and old natural fiber as raw material, other fiber refers to low melting point fiber or bicomponent fiber, PP fiber, waste and old natural fiber and Other fibers are opened with an opener, mixed with a cotton blender after opening, and then carded with a carding machine to evenly distribute PP fibers, waste natural fibers and other fibers; The netting machine is used for cross-laying, and after the netting is completed, the needle punching machine is used for pre-punching and reinforcement to form an ecological blanket base material, and then the ecological blanket base material is thermally bonded to form an ecological blanket for road slope protection.

Embodiment 3

[0021] Embodiment three: a kind of preparation method of road slope protection ecological blanket, comprises the following steps: A, take PP fiber and waste and old natural fiber as raw material, other fiber refers to the naturally degradable fiber that length is greater than 23mm. The PP fibers, waste natural fibers and other fibers are respectively opened by an opener, and then mixed by a cotton mixer after opening, and then carded by a carding machine to evenly distribute the PP fibers, waste natural fibers and natural fibers; B. The combed fibers are cross-laid with a web lapper, and then the fiber web and the base cloth are needle-punched to make the ecological blanket for road slope protection strong; the base cloth includes cotton cloth and PP cloth. The cost of the base cloth is low, and it can be degraded naturally.
