Staple Geotextile Lightweight And Durable For Highway And Railway Projects
Product Introduction
The main raw material of staple fiber geotextile is polypropylene or polyester staple fiber. These fibers have amorphous fiber tissue, forming a network structure with anisotropic and motility, so the mesh is not easy to plug. At the same time, this structure also ensures high water permeability, even under the pressure of earthwork can still maintain good water permeability.
Product Properties
Staple fiber geotextile also has corrosion resistance, polypropylene or polyester and other chemical fibers as raw materials, can resist acid and alkali, no corrosion, no moth, anti-oxidation.
Product Application
Staple fiber geotextile is widely used in many fields because of its unique properties. It can be used as an isolation material to deal with surfaces with complex terrain or large curvature. In water conservancy projects, staple fiber geotextile can be used for seawall, river embankment, river embankment, lake embankment projects and reservoir reinforcement projects. In highway, railway and airport engineering, it can be used in soft foundation reinforcement treatment, slope protection, road remote reflection, fracture structure bumble, drainage system and green isolation belt. In addition, the staple fiber geotextile is also suitable for environmental protection engineering, power plant engineering and port waterway engineering and other fields.
