Geotextile knowledge points
Geotextiles, also known as geotextiles, are engineering materials made of fibrous or sheet-like materials that are used to strengthen soil, improve soil properties, and isolate soil from water. It usually takes the form of non-woven or woven cloth.
Function: Geotextiles have a variety of functions, including filtration, isolation, anti-scouring, reinforcement and protection, etc. Different types of geotextiles can provide different functions according to specific engineering needs.
Filtration: Geotextiles can filter particles in the soil while allowing water to pass through, preventing particle erosion and maintaining the stability of the soil layer.
Isolation function: Geotextiles can isolate impurities and particle mixing between different soil layers, and prevent mutual penetration and pollution between different soil layers.
Anti-scouring effect: In the environment of water erosion, geotextiles can slow down the speed of water flow, disperse the energy of water flow, and prevent the soil from being washed away.
Reinforcement: Geotextiles can increase the strength and stability of the soil and reduce ground subsidence and deformation.
Protection: Geotextiles can be used as a protective layer to protect the underlying soil or other structures from damage.
Classification: According to different structures and manufacturing methods, geotextiles can be divided into two types: non-woven geotextiles and woven geotextiles. Non-woven geotextiles are mainly made by bonding fibers, while woven geotextiles are composed of interwoven fiber threads.
Application fields: Geotextiles are widely used in water conservancy engineering, road engineering, railway engineering, foundation engineering, environmental engineering and other fields. Specific applications include soil filtration, roadbed reinforcement, soil erosion control, reservoir dam seepage prevention, etc.
Installation method: The installation methods of geotextiles include tiling method, covering overlapping method, winding and fixing method, etc. The specific method is selected according to the engineering requirements and the characteristics of geotextiles.
What does the anti-aging of geotextiles depend on?
Geotextiles have certain anti-aging properties, but their specific anti-aging properties depend on factors such as the type of material used, additives, and manufacturing processes.
Material selection: Geotextiles can be made of various materials, such as polypropylene (PP), polyester (PET), etc. The aging resistance of different materials will be different. Generally speaking, the aging resistance of polyester is better, while that of polypropylene is relatively weak.
Additives: During the manufacturing process of geotextiles, some anti-aging additives may be added to improve its weather resistance. These additives can resist the erosion of ultraviolet rays, oxidants and other environmental factors on the geotextile, prolonging its service life.
Coating treatment: Some geotextiles will be coated to enhance their aging resistance. The coating usually includWhat does the anti-aging of geotextiles depend on?es anti-ultraviolet, waterproof, anti-pollution and other functions, which can effectively prolong the service life of the geotextile.
Manufacturing process: The manufacturing process of geotextiles will also affect its aging resistance. Reasonable production process and quality control can improve the consistency and stability of geotextiles, thereby improving their aging resistance.
Storage and use conditions: When storing and using geotextiles, avoid prolonged exposure to strong sunlight, and try to avoid friction, tearing and damage. Proper storage and usage conditions can help prolong the service life of geotextiles.
Manufacturer and quality certification: choose a geotextile manufacturer with good reputation and experience, and ensure that its products meet the relevant quality certification standards, which can provide more reliable aging resistance.
