Corrosion Resistant Acid And Alkali Drainage Special Short Fiber
Geotextile
Product Introduction
Staple fiber geotextile is a kind of water-permeable geosynthetic
material made of synthetic fiber by needling or weaving. Its main
raw material is usually polypropylene or polyester staple fiber. In
the production process, these fibers will go through a series of
technological steps such as opening, combing, clutter, laying nets
and needling, and finally made into cloth.
Product Properties
1. Water permeability: Staple fiber geotextile has high water
permeability, even under the pressure of earthwork, it can maintain
good water permeability. This characteristic allows it to
effectively control the water table and prevent the accumulation of
water, thus improving the stability of the foundation.
2. Corrosion resistance: The staple fiber geotextile is made of
acid and alkali resistant chemical fiber materials, which will not
be corroded by acid and alkali substances, nor will it be eaten or
oxidized, which makes it have a long service life.
3. Simple construction: short fiber geotextile light weight, easy
to use, easy to construction. It can be tailored and used according
to specific needs, reducing the difficulty and cost of
construction.
4. Tensile strength: Although the fracture strength and other
parameters of staple fiber geotextile may not be as high as that of
filament geotextile, it still has a certain tearing resistance and
tensile strength. This makes it show good adaptability when dealing
with surfaces with complex terrain or large curvature.
Product Application
1. Water conservancy projects: In water conservancy projects,
staple fiber geotextiles can be used for dam filtration, channel
isolation and seepage prevention. It can effectively prevent water
penetration, protect soil structure, and prevent soil erosion.
2. Road and airport construction: staple fiber geotextile can be
used for road and airport runway foundation isolation, reverse
filtration, drainage, soil slope, retaining wall and pavement
reinforcement, drainage, etc. It can enhance the structural
stability of the road and improve the durability.
3. Port engineering: In port engineering, staple fiber geotextile
can be used for soft foundation treatment, beach embankment, harbor
pier and breakwater reinforcement, drainage, etc. It can
effectively improve the stability of soft soil foundation and
reduce project risk.
4. Landfill and mine tailings dam: Staple fiber geotextile can be
used for landfill, thermal power plant ash dam, mine tailings dam
isolation and seepage prevention. It can prevent pollutants from
penetrating into groundwater and protect the environment.
