Staple Geotextile Effective Filtration For Landfills And Waste
Management
Product Introduction
Staple fiber geotextile with good filtration performance is a
geomaterial made of staple fiber as raw material by non-woven
production equipment, which plays an important filtering role in
civil engineering.
Product Properties
1. Good water permeability: the short fiber geotextile has a gap
between the fibers, so it has good water seepage performance, can
make water flow through, and effectively intercept soil particles,
fine sand, small stone, etc., to prevent soil erosion.
2. Corrosion resistance: staple fiber geotextile with polypropylene
or polyester and other chemical fiber as raw materials, with acid
and alkali resistance, no corrosion, no moth, anti-oxidation
characteristics.
3. Microbial resistance: It is not damaged by microorganisms and
insects, and maintains the stability and functionality of the
material.
4. Convenient construction: Due to the light and soft material, the
transport, laying and construction of short fiber geotextile are
convenient.
Product Application
1. Hydraulic engineering: In reservoirs, DAMS and other projects,
staple fiber geotextiles play the role of isolation and filtration
to prevent the loss of fine particles of soil.
2. Road construction: used for reinforcement of railway roadbed,
maintenance of highway pavement, improve the bearing capacity and
stability of roadbed.
3. Environmental protection engineering: In landfills, sewage
treatment plants and other projects, staple fiber geotextiles can
prevent the spread of pollutants, while having drainage and
isolation functions.
4. Slope engineering: In slope protection, staple fiber geotextiles
can prevent soil erosion and landslide and improve slope stability.
