The Role of Geotextiles
1. Isolation Effect
Geotextiles can be used to isolate building materials with different physical properties, such as soil and sand, soil and concrete.
2. Filtration (inverse filtration) Effect
Geotextile has good air permeability and water permeability, which can allow water flow through, while intercepting fine sand, small stones, etc., to maintain the stability
of soil and water engineering.
3. Drainage Function
Geotextile has good water conductivity, can form a drainage channel inside the soil, the excess liquid and gas in the soil structure discharge.
4. Reinforcing Effect
Geotextile can enhance the tensile strength and deformation resistance of soil, so as to enhance the stability of building structure and improve the quality of soil.
5. Protective Effect
Geotextile can diffuse concentrated stress, transfer stress, prevent soil from being damaged by external force, and play a protective role. This is particularly common in river
regulation, bank protection, bottom protection works, as well as coastal moisture, road slope protection and other works.
6. Anti-puncture Effect
Combined with geomembrane, geotextile can play a role in preventing puncture, thus improving the effect of composite waterproof and impermeable materials.
7. Environmental Protection and Ecological Restoration
Geotextiles can also play a role in environmental protection and ecological restoration. It can be used as a growth medium for plants, promote plant growth and root development,
and repair vegetation cover and ecosystems. In addition, geotextiles can also be used for the closure and isolation of landfills and tailings ponds, effectively controlling and
reducing the leakage and diffusion of pollutants.
In summary, geotextile can play a variety of functions in land engineering and environmental protection, such as protection, enhancement, filtration and repair, and has a wide range
of application prospects.
