Geotextile can be called a veteran product in geotechnical materials. It occupies an important position in the development of geotechnical materials and is a pioneer product of its development. It has been widely used in many fields. Geotextiles have the functions of filtration, drainage, isolation, reinforcement, and protection. They have the characteristics of light weight, high tensile strength, good permeability, high temperature resistance, freeze resistance, aging resistance, and corrosion resistance. Let's talk about how the geotextile works in the process of use?
Geotextile
1. When water flows from the fine soil layer to the coarse soil layer, the good air permeability and water permeability of the geotextile are used to make the water flow through and effectively carry the soil particles, fine sand, small stones, etc. to maintain the water and soil engineering Of stability.
2. The geotextile has good water conductivity, it can form drainage channels inside the soil, and discharge excess liquid and gas in the soil structure.
3. When the water flow scours the soil, the geotextile effectively diffuses, transfers or decomposes the concentrated stress, prevents the soil from being damaged by external forces, and protects the soil.
Filament geotextiles are often used in farmland water conservancy projects, so in order to ensure their role, what should we pay attention to? I will give you an analysis below.
I. It is recommended to use thick, thick filament geotextiles for isolation and protection. It can also increase the ground temperature, which is helpful to prevent frost heaving and damage of water channels. 200 grams of filament geotextiles are used as the bottom protection of stone masonry. Played a good role.

2. It is recommended to choose the national standard filament geotextile. The filament geotextile is susceptible to damage by masonry in the channel. At the same time, the irregular operation of the construction staff may also cause damage to the geotextile. The national standard geotextile has high strength. Puncture resistance and durability consistently maintain excellent performance. Conversely, the non-standard filament geotextiles provided by other companies use too much recycled material, and the strength drops quickly. once a little damage, it will cause large-scale damage and cause the entire project to fail.
3. It is recommended to choose the appropriate width and roll length. The width and roll length should be selected according to the specific length and overlap of the channel section, and combined with the convenience of workers' construction. The recommended product is 6 meters wide and 50 meters long.
Fourth, do a good job in product protection, long-term geotextiles are not easy to be exposed to sunlight for a long time. Pay attention to product protection during storage and construction, and use plastic film or other coverings for sun protection and waterproof treatment.
