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.
