The main applications of long-fiber geotextiles are concentrated in geotechnical engineering and water conservancy construction. Their core functions include isolation, reverse filtration, drainage, structural protection and reinforcement . The following are specific application scenarios: Foundation engineering protection isolation of different material layers : It is used in projects such as roadbeds and airport runways to isolate ballast from soft foundations and prevent material mixing. Youdaoplaceholder0 Enhance foundation stability : As a reinforcing material in retaining wall backfilling and slope reinforcement, it increases the tensile strength of the structure and prevents soil erosion. For instance, in the construction of wrapped retaining walls, long-fiber geotextiles can effectively disperse lateral pressure. Youdaoplaceholder0 water conservancy engineering application seepage prevention and reverse filtration : In embankment and channel engineering, water flow is allowed to pass through but soil particles are intercepted to prevent seepage and dam body erosion. Youdaoplaceholder0 Typical case: As a filter layer for the dam body, it balances water pressure and maintains structural stability. Youdaoplaceholder0 drainage system construction : It is used for seepage diversion in scenarios such as tunnels and Wells, and for reducing the groundwater level or lining pressure. Youdaoplaceholder0 Road engineering crack repair and isolation layer : Prevent the expansion of reflective cracks in flexible pavements, reduce frost damage and material consumption. Youdaoplaceholder0 Weak foundation treatment : Enhance the bearing capacity of the roadbed through reinforcement to extend the service life of the road. Environmental protection and resource conservation reduce the consumption of traditional materials : replace stone and cement for isolation layers to lower the pressure on mining. Youdaoplaceholder0 Chemical corrosion resistance and durability : Suitable for harsh environments such as chemical waste residue landfills, it can withstand long-term acid and alkali erosion. The performance characteristics of long-fiber geotextile are closely related to the production process of polyester long-fiber non-woven fabric, and its application scenarios can be further expanded to other sub-sectors of geosynthetic materials.
