Description

Technical Field

[0001] The utility model belongs to the technical field of punching equipment, in particular to a punching section of a polyester grille net for isolating and protecting the periphery of a highway. Background Art

[0002] Highway slope protection is a key component of highway engineering, and its main purpose is to prevent soil erosion, protect the stability of the roadbed, and ensure the safety and smooth operation of the highway. It involves many aspects, including design, material selection, construction methods, and subsequent maintenance management.

[0003] In terms of material selection, highway slope protection can use a variety of materials, including natural stone, concrete, geogrid, vegetation, etc. Natural stone and concrete slope protection have good stability and durability, but the cost is high and has a greater impact on the ecological environment. Geogrid and vegetation slope protection are more environmentally friendly and economical, and can effectively prevent soil erosion and improve the ecological environment.

[0004] There are many materials for geogrids. Polyester materials are also called polyethylene terephthalate (PET). Polyester materials have many advantages, such as good fiber-forming and mechanical properties: polyester fibers have good strength, wear resistance and creep resistance; chemical corrosion resistance: polyester materials have good resistance to chemical substances, especially acids and alkalis; electrical insulation: polyester has good electrical insulation properties; light and comfortable: compared with some synthetic fibers, polyester fibers are lighter and suitable for making summer clothing; easy to process: polyester materials can be made into products of different shapes through a variety of processing methods; cost-effective. The price of polyester materials is relatively low and suitable for large-scale industrial production. Therefore, thin sheets made of polyester materials will be selected for further processing into grid shapes.

[0005] For grid-shaped punching processing, the conventional operation is to pause the passing material before punching. This punching method will reduce the efficiency of punching and extend the processing cycle. Utility Model Content
