[0022] Please refer to Figure 1-4 The acid-alkali resistant reinforced geotextile comprises a fabric body 1, a reinforcement edge 2 is arranged on the outer side of the fabric body 1, and a reinforcing rib 3 is arranged inside the fabric body 1.

[0023] The fabric body 1 includes an anti-corrosion layer 11, which is arranged on the lower surface of the fabric body 1, a filter layer 12 is arranged at the other end of the anti-corrosion layer 11, a waterproof layer 13 is arranged at the other end of the filter layer 12, an adhesive layer 14 is arranged at the other end of the waterproof layer 13, and the adhesive layer 14 is arranged on the upper surface of the fabric body 1, the anti-corrosion layer 11 is composed of a polyvinyl chloride (PVC) coating, PVC is a common waterproof material with good chemical corrosion resistance, and arranging the PVC coating on the lower surface of the geotextile can effectively prevent the lower part of the geotextile in contact with the substrate from being eroded by moisture and chemicals, extend the service life of the geotextile, and protect the substrate structure from corrosion and damage, the filter layer 12 is composed of polypropylene (PP), the filter layer 12 generally has good water permeability and filtering performance, can prevent the penetration of soil particles under the geotextile, while allowing moisture and The gas passes through to maintain good contact between the geotextile and the base, which helps to reduce leakage and water storage at the bottom of the geotextile, and prevents the geotextile from being blocked by soil particles and affecting its performance. The waterproof layer 13 is composed of polyvinyl chloride (PVC), which is a common waterproof material with good chemical corrosion resistance and wear resistance. The waterproof layer 13 is arranged at the other end of the filter layer 12 to effectively prevent moisture from penetrating into the bottom of the geotextile, protect the foundation structure from moisture erosion, and extend the service life of the project. The adhesive layer 14 is composed of an adhesive coating, which usually uses materials such as acrylic acid or hot melt adhesive, and can provide good adhesion and sealing. The adhesive coating can simplify the installation process of the geotextile, reduce construction time and cost, and ensure the close fit between the waterproof layer 13 and the base structure, thereby improving the waterproof performance of the project.

[0024] The fabric body 1 is movably engaged in the reinforcement edge 2, and a slot matching the fabric body 1 is provided inside the reinforcement edge 2. The reinforcement edge 2 is made of polyester PET material. Polyester (PET) is a material with good strength and durability. Making the reinforcement edge 2 of polyester material can ensure that it has sufficient strength to support the fabric body 1, and can withstand long-term use and environmental influences without being easily worn or broken. The polyester (PET) material usually has a certain flexibility and can adapt to fabric bodies 1 of different shapes and sizes, and can be bent and deformed to a certain extent without being damaged or losing function. This flexibility enables the reinforcement edge 2 to better coordinate with the fabric body 1 to form a tight connection. The polyester (PET) material usually has high corrosion resistance and can resist erosion by factors such as water, chemicals and ultraviolet rays. This means that the reinforcement edge 2 can maintain stability and performance under various environmental conditions and is not easily weakened or failed due to corrosion. Polyester (PET) is a relatively economical material with good performance and availability. Therefore, using polyester (PET) material to form the reinforcement edge 2 can reduce manufacturing costs, making the design more cost-effective and suitable for engineering projects of various sizes;

[0025] The reinforcement ribs 3 are arranged in a mesh structure. The reinforcement ribs 3 are made of glass fiber material. Glass fiber has an excellent strength-to-weight ratio and can provide good strength and rigidity while maintaining lightweight characteristics. This means that the reinforcement ribs 3 can reduce the dead weight of the structure while ensuring the structural strength, thereby reducing the overall load and improving the bearing capacity of the structure. Glass fiber has excellent corrosion resistance and is not easily corroded by water, chemicals or climate change. Therefore, the reinforcement ribs 3 made of glass fiber material can maintain stability and performance in a humid, high temperature or chemically corrosive environment, thereby extending the service life of the structure. The glass fiber material has good plasticity and can be flexibly adjusted according to design requirements. The shape and size can be adjusted, and various complex shapes of reinforcing ribs 3 can be made through molding, extrusion or stretching and other processing techniques. This plasticity enables the glass fiber reinforcing ribs 3 to adapt to different structural forms and construction requirements. Glass fiber is a good electrical insulating material with excellent insulation properties. Therefore, the application of glass fiber reinforcing ribs 3 in electrical equipment or building structures can effectively prevent electrical leakage or insulation failure, and improve the safety and reliability of equipment and structures. Glass fiber material is a recyclable and environmentally friendly material that conforms to the concept of sustainable development. After the service life of the reinforcing ribs 3 ends, they can be recycled and reused to reduce resource waste and reduce environmental load.
