[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] Reference Figure 1 and Figure 2The utility model embodiment is a geotextile with anti-seepage and anti-filtration capabilities, which includes a base fabric layer 1, an upper cushion layer 2 and a protective layer 3 are provided on one side of the base fabric layer 1, the protective layer 3 is far away from the base fabric layer 1, and a lower cushion layer 4 and a bottom layer 5 are provided on the other side of the base fabric layer 1, and the bottom layer 5 is far away from the base fabric layer 1; the base fabric layer 1 includes a base layer 11, an anti-filtration layer 12 provided on one side of the base layer 11 and an anti-seepage layer 13 provided on the other side of the base layer 11, the protective layer 3 can be selectively covered with vegetation or rocks to prevent external water flow or wave impact, weathering erosion, freezing damage and shielding sunlight ultraviolet rays, etc. The upper cushion layer 2 serves as a transition layer between the protective layer 3 and the base fabric layer 1, which can prevent the protective layer 3 from being directly placed on the base fabric layer 1 to damage the base fabric layer 1. The base fabric layer 1 serves as the anti-seepage and anti-filtration body, which can effectively prevent moisture in the soil from passing through the interlayer and causing damage to the building structure. The underlying layer 4 arranged below the base fabric layer 1 can play the role of drainage and exhaust, ensuring the dryness and stability of the environment below the geomembrane, while protecting the base fabric layer 1 from damage by the bottom layer 5. The bottom layer 5 between the base fabric layer 1 and the soil can provide good basic support and protection. The geotextile as a whole has multiple aspects such as waterproofing, protection, drainage, and exhaust, providing comprehensive and effective protection for the building structure, and significantly improving the reliability and safety of the project.

[0022] The base layer 11 is made of polyester fiber, the anti-permeation layer 13 is made of polyvinyl chloride, and the filter layer 12 is made of nylon fiber. The base layer 11 made of polyester fiber has the characteristics of high strength and wear resistance. The anti-permeation layer 13 made of high molecular material made of polyvinyl chloride has excellent waterproof performance and can effectively prevent liquid penetration. The filter layer 12 made of nylon fiber can easily achieve a specific pore size and porosity by adjusting the diameter and arrangement of the fiber, which can not only filter soil particles and prevent blockage, but also maintain good drainage performance.

[0023] Reference Figure 3 The upper cushion layer 2 includes a first non-woven fabric layer 21 and gravel material 22 filled in the first non-woven fabric layer 21. The woven fabric has good air permeability and water permeability, and has a certain tensile strength. The first non-woven fabric layer 21 wraps the gravel material 22 and can be used as a transition layer between the protective layer 3 and the base fabric layer 1 to prevent the protective layer 3 of large pieces of rough material from damaging the base fabric layer 1.

[0024] Reference Figure 4 The lower cushion layer 4 includes a second non-woven fabric layer 41 and a fine soil layer 42 filled in the second non-woven fabric layer 41. The non-woven fabric has good air permeability and water permeability, and has a certain tensile strength. The second non-woven fabric layer 41 is used to wrap the fine soil layer 42 to help maintain the stability of the soil and reduce water loss.

[0025] Working principle: The protective layer 3 can be covered with vegetation or rocks to prevent external water flow or wave impact, weathering erosion, freezing damage and shielding sunlight ultraviolet rays, etc. The upper cushion layer 2 serves as a transition layer between the protective layer 3 and the base fabric layer 1, which can prevent the protective layer 3 from being directly placed on the base fabric layer 1 to damage the base fabric layer 1. The base fabric layer 1, as the main body of anti-seepage and anti-filtration, can effectively prevent the moisture in the soil from passing through the interlayer and causing damage to the building structure. The lower cushion layer 4 located below the base fabric layer 1 can play the role of drainage and exhaust, ensuring the dryness and stability of the environment under the geomembrane, while protecting the base fabric layer 1 from damage by the bottom layer 5. The bottom layer 5 between the base fabric layer 1 and the soil can provide good basic support and protection. The geotextile as a whole has multiple aspects such as waterproofing, protection, drainage, and exhaust, providing comprehensive and effective protection for the building structure, and significantly improving the reliability and safety of the project.

[0026] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
