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.
