Polyester Staple Fiber Needle Punched Geotextile
1. Filtration: Traps soil particles while allowing water to pass through, preventing piping and clogging (for drainage in dams, embankments and road subgrades).
2. Drainage: Quickly drains seepage from soil and structures, reducing pore water pressure.
3. Separation: Separates soils/aggregates of different particle sizes, subgrade and base course, preventing mixing and maintaining structural stability.
4. Reinforcement: Improves the tensile strength of soil, limits settlement, and enhances the stability of slopes and soft foundations.
Polyester Staple Fiber Needle Punched Geotextile (short name: Polyester Staple Geotextile) is a non-woven geosynthetic material made from polyester (PET) staple fibers via the needle punching process. Its core advantages include filtration, drainage, separation, reinforcement and protection. Featuring high cost performance and convenient construction, it is a mainstream material in geotechnical engineering.
Five Core Functions
1. Filtration: Traps soil particles while allowing water to pass through, preventing piping and clogging (for drainage in dams, embankments and road subgrades).
2. Drainage: Quickly drains seepage from soil and structures, reducing pore water pressure.
3. Separation: Separates soils/aggregates of different particle sizes, subgrade and base course, preventing mixing and maintaining structural stability.
4. Reinforcement: Improves the tensile strength of soil, limits settlement, and enhances the stability of slopes and soft foundations.
5. Protection: Covers slopes and anti-seepage membranes, resisting erosion and puncture, and protecting structures.
Typical Engineering Application Scenarios
1. Transportation Engineering: Road/railway subgrade reinforcement, pavement crack prevention, soft ground treatment, slope protection
2. Water Conservancy Engineering: Dam filter drainage, river channel slope protection, reservoir impermeable layer protection, canal isolation
3. Environmental Protection Engineering: Landfill (liner protection, final cover), tailings pond, leachate treatment
4. Municipal and Construction Engineering: Underground garage roof drainage, sports field foundation, tunnel lining drainage, airport runway
5. Land Reclamation from Sea / Coastal Mudflat: Soft ground reinforcement, isolation and drainage, scour protection
