Staple Geotextile Lightweight And Durable For Highway And Railway Projects
Product Introduction
Staple fiber geotextile is an important geosynthetic material, mainly from polyester or polypropylene staple fiber as raw materials, through the opening, carding, clutter, laying and needling technology to produce.
Product Properties
1. The mesh is not easy to plug: The network structure formed by the amorphous fiber tissue has a deformation and movement.
2. High permeability: under the pressure of earthwork, it can still maintain good water permeability.
3. Corrosion resistance: polypropylene or polyester and other chemical fiber as raw materials, acid and alkali resistance, no corrosion, no moth, anti-oxidation.
4. Easy construction: light weight, easy to use.
Product Application
1. Environmental protection projects: such as landfills, industrial slag fields of chemical plants, etc.
2. Water conservancy projects: including seawall, river dyke, river dyke, lake dyke project, reservoir reinforcement project, encircling reclamation project, flood prevention and rescue.
3. Highway, railway and airport engineering: used for soft foundation reinforcement treatment, slope protection, road remote reflection, fracture structure bumble, drainage system, green isolation belt and so on.
4. Power plant engineering: nuclear power plant foundation engineering, thermal power ash dam engineering, hydropower station engineering.
5. Port channel engineering: port wharf engineering, ship lock engineering, channel management engineering, etc.
