Geotextile is a special material used in civil engineering and environmental engineering, often used for soil reinforcement and protection. It is made of synthetic materials such as polyester, polypropylene or polyethylene, and has the characteristics of anti-corrosion, anti-aging, corrosion resistance and high strength.
The main application range of geotextiles
Soil reinforcement: Geotextiles are often used for soil reinforcement. For example, in foundation projects such as roads, railways, and airport runways, geotextiles can be laid as soil reinforcement materials to improve the stability and bearing capacity of the foundation.
Soil filtration and drainage: Geotextiles have good water permeability and filtration properties, and can be used for soil filtration and soil and water conservation. In embankments, dams, river courses and earthworks, geotextiles can be used to filter particulate matter in water, prevent soil erosion, and at the same time achieve soil drainage and water storage regulation through the water permeability of the material.
Prevent soil erosion: Geotextiles can be used to prevent soil erosion, especially for steep slopes and areas prone to erosion. By laying geotextiles on the soil surface or at a position perpendicular to the direction of water flow, soil particles can be effectively fixed to prevent the erosion and erosion of the soil by wind, rain and water.
Reduce soil subsidence and deposition: Geotextiles can also be used to reduce soil subsidence and deposition. In earth filling projects, the use of geotextiles can limit the settlement of the fill layer and provide a more uniform load-bearing capacity, thereby protecting the stability of the foundation structure.
Waste treatment and environmental protection: Geotextiles can also be used in waste treatment and environmental protection projects. For example, in landfills, geotextiles can be used to isolate waste from the soil, preventing waste from seeping or contaminating soil and groundwater.
In conclusion, geotextiles have a wide range of applications in civil engineering and environmental engineering. It can provide soil reinforcement, filtration, anti-corrosion and fixation functions, protect the stability of the infrastructure and the safety of the environment
