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.
