[0023] like Figure 2As shown in the figure, the material of the resin impregnation layer 2 is epoxy resin, which has excellent mechanical properties and corrosion resistance and is often used to coat or impregnate geotextiles to enhance their strength and durability. The material of the fiber reinforcement layer 3 is carbon fiber, which is a fiber material with extremely high strength and light weight. Adding carbon fiber to the geotextile can significantly improve the strength of the geotextile, making it more suitable for applications requiring high strength and stiffness.

[0024] Working principle: The resin impregnated layer 2 is the base layer of the geotextile. By impregnating the geotextile in resin, its strength, stability and durability can be increased. The resin impregnated layer 2 is usually located at the bottom of the geotextile, directly in contact with the surface, and plays a supporting and protective role. The waterproof layer 5 is located above the resin impregnated layer 2. Its function is to prevent moisture from penetrating into the geotextile. This layer usually uses materials with good waterproof properties, such as special polymers or rubber, to ensure that the geotextile remains dry in a humid environment and prevent moisture from eroding the geotextile. The anti-corrosion layer 6 is located above the waterproof layer 5 and is mainly used to enhance the corrosion resistance of the geotextile. This layer usually contains anti-corrosion ingredients, which can effectively resist the erosion of the geotextile by chemicals, microorganisms, etc., and extend its service life.

The filter layer 9 is located above the reverse osmosis membrane layer 4. Its function is to prevent the geotextile from being blocked by particulate matter and maintain the water permeability of the geotextile.
