Staple Geotextile Durable and Corrosion-Resistant for Environmental Engineering
Product Introduction
Staple fiber geotextile is a kind of geomaterial with good water permeability, which is widely used in civil engineering.
Product Properties
1. Water permeability: water permeable short fiber geotextile has good permeability and water permeability, can make water flow through, while effectively intercepting soil particles, fine sand, small stone, etc., to maintain the stability of soil and water engineering.
2. Filterability: When water flows from the fine soil layer into the coarse soil layer, the permeable staple fiber geotextile can play a filtering role to prevent soil loss.
3. Durability: It has good tensile strength and deformation resistance, which can enhance the stability of the building structure.
4. Corrosion resistance: can resist the erosion of a variety of chemical substances, suitable for different environmental conditions.
Product Application
1. Water conservancy projects: In reservoirs, DAMS, canals and other projects, permeable staple fiber geotextiles are used for reinforcement and filtration.
2. Road construction: improve the bearing capacity and stability of the roadbed, extend the service life of the road.
3. Environmental engineering: Prevent the spread of pollutants in landfills, sewage treatment plants and other projects.
4. Slope engineering: Used for slope protection to prevent soil erosion and landslides.
