Description

Technical Field

[0001] The utility model relates to the technical field of geotextiles, in particular to a special cold-resistant geotextile for high-altitude areas. Background Art

[0002] High altitude areas refer to areas with higher altitudes, usually located in mountains, plateaus or alpine areas. The climatic conditions in high altitude areas are usually cold and dry, with large temperature fluctuations and obvious temperature differences between day and night. As the altitude increases, the temperature tends to decrease and the air pressure will decrease accordingly. In order to protect the soil in plateau areas, geotextiles are needed. Cold-resistant geotextiles are a special geotechnical material used in civil engineering, protective engineering and environmental protection. They are designed to provide excellent protection and enhance soil functions in cold environments.

[0003] After searching: Chinese patent announcement number: CN216507234U, it relates to the field of geomembrane technology, and discloses an environmentally friendly smooth high-density polyethylene geomembrane, including a first anti-seepage layer, a reinforcement layer, a substrate layer and a second anti-seepage layer arranged from top to bottom, the first anti-seepage layer, the reinforcement layer, the substrate layer and the second anti-seepage layer are fixedly welded, the first anti-seepage layer and the second anti-seepage layer are fixedly welded on the opposite sides thereof, the substrate layer is made of chlorinated polyethylene, the reinforcement layer is made of cross-linked polyethylene, the first geotextile layer and the second geotextile layer are both made of high-density polyethylene, the first anti-seepage layer and the second anti-seepage layer are both made of chlorosulfonated polyethylene, and the surfaces of the first geotextile layer and the second geotextile layer are both provided with a plurality of uniformly distributed anti-slip bumps. The utility model not only effectively improves the chemical corrosion resistance and wear resistance, but also effectively improves the heat and cold resistance and mechanical properties.

[0004] The above patent records that "chlorinated polyethylene has good impact resistance and insulation performance, cross-linked polyethylene is heat-resistant and cold-resistant, has good mechanical properties, high-density polyethylene has high mechanical strength and long service life, chlorosulfonated polyethylene is resistant to ozone, chemical corrosion, oil, heat, light, wear and tensile strength, and the anti-slip bumps 7 improve the anti-slip properties of the surface of the first geotextile layer 6 and the second geotextile layer 1. The 2.2 cm spacing not only ensures the use effect but also reduces the production cost. The 0.6 mm first impermeable layer 5 and the second impermeable layer 2 have good use effect and long service life", which can increase the service life of the geotextile, but for geotextiles exposed to plateau pressure and temperature for a long time, the internal wear and breakage of the geotextile will increase. Therefore, in response to the above-mentioned deficiencies, a new type of cold-resistant geotextile specially used in high altitude areas is proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a special cold-resistant geotextile for high-altitude areas, including a geotextile main body 1, the function of the geotextile main body 1 is to connect multiple internal structures, and it is mainly used for soil reinforcement, drainage, protection and filtration in various civil engineering projects. Two protective layers 3 are arranged inside the geotextile main body 1. The material of the protective layer 3 is polyester. Polyester has good wear resistance and can provide additional protection in the protective layer 3. It also has good UV resistance and weather resistance, which helps to protect the structure from erosion by natural environments such as sun and rain. A plurality of mounting holes 2 are opened inside the geotextile main body 1. The mounting holes 2 are set to facilitate the staff to use rivets to fix the geotextile main body 1. The adjacent ends of the two protective layers 3 are fixedly connected with an anti-corrosion layer 4. The material of the anti-corrosion layer 4 is glass fiber. Glass fiber has excellent corrosion resistance and can effectively prevent the erosion of other materials by corrosive media. It is a high-strength and rigid material. By using glass fiber in the anti-corrosion layer 4, the overall strength and rigidity of the structure can be increased, and its performance in terms of resistance to wind loads, earthquake loads, etc. can be improved. The adjacent ends of the two anti-corrosion layers 4 are fixedly connected with a reinforcement layer 5, and the reinforcement layer 5 is made of polypropylene fiber. Polypropylene fiber has high strength and can increase the tensile strength and tear resistance of the overall structure. Polypropylene fiber has good weather resistance and corrosion resistance, which can enhance the durability of the structure and extend its service life.

[0023] Reference Figure 2The adjacent ends of the two reinforcing layers 5 are fixedly connected with an insulation layer 6. The insulation layer 6 is made of foam plastic. The foam plastic has good thermal insulation performance, can effectively reduce the conduction and loss of heat, and has a certain airtightness, can prevent water vapor penetration, keep the internal dry state of the structure, and extend the service life. The adjacent ends of the two insulation layers 6 are provided with an air layer 7. The air layer 7 is provided because air is a relatively poor heat conductive medium. By providing an air layer 7 between the two insulation layers 6, the thermal resistance of the entire structure can be increased, the conduction of heat can be hindered, and thus the insulation effect can be improved. The adjacent ends of the two insulation layers 6 are fixedly connected with a waterproof component. The interior of the waterproof component is fixedly connected with an anti-cracking layer 9. The material of the anti-cracking layer 9 is polyurethane. Polyurethane has good elasticity and toughness, can reduce the stress concentration when the structure is subjected to external loads, thereby reducing or preventing cracks. Polyurethane has good adhesion and can be well combined with other materials to form a continuous and strong anti-cracking layer 9.

[0024] Reference Figure 2 The waterproof component includes a waterproof layer 8 and a wear-resistant layer 10. The top of the waterproof layer 8 is fixedly connected to the bottom of one of the thermal insulation layers 6, and the bottom of the wear-resistant layer 10 is fixedly connected to the top of one of the thermal insulation layers 6. The waterproof layer 8 is made of polyvinyl chloride. The waterproof layer 8 has good waterproof performance, can effectively prevent the penetration and leakage of water, protect the interior of the structure from water damage, and has good weather resistance. It can resist the influence of external environment such as ultraviolet rays, high temperature, cold, etc., and extend the service life of the waterproof layer 8. The wear-resistant layer 10 is made of polyethylene. Polyethylene has a certain airtightness, which can prevent moisture from penetrating into the interior of the structure and avoid moisture erosion and damage to structural materials.

[0025] Working principle: The geotextile body 1 is used for soil reinforcement, drainage, protection and filtration in various civil engineering projects. The multiple installation holes 2 opened inside are for the convenience of the staff to fix the tools used on the geotextile body 1. The protective layer 3 can increase the tensile strength of the geotextile, improve its ability to resist external tensile force, and provide anti-ultraviolet performance to prevent the geotextile from aging and degradation under sunlight, thereby extending the service life of the geotextile. The pre-cut glass fiber cloth is manually placed layer by layer in the mold to be combined. By using glass fiber as the material of the anti-corrosion layer 4, it can provide superior corrosion resistance, chemical resistance, mechanical strength and insulation performance, making the structure more stable and reliable in harsh environments, and by covering or wrapping the reinforcing layer 5 polypropylene fiber on the outside of the glass fiber. The strength, rigidity and wear resistance of the fiber are increased while the softness of polypropylene is maintained. The impact resistance of the geotextile is increased through the combination of polypropylene fibers, making it more able to withstand external impact and reducing the risk of damage caused by external forces. The polypropylene fiber and foam plastic are heated and softened separately, and then stacked together and hot-pressed at a certain temperature and pressure. The insulation layer 6 uses foam plastic as the material, and the foam plastic has good thermal insulation properties. It can improve the thermal insulation effect of the geotextile to a certain extent and protect the material from low temperature.

[0026] The air layer 7 is opened to increase the thermal resistance of the entire structure, hinder the conduction of heat, and thus improve the thermal insulation effect. The thermal insulation layer 6 is fixedly connected with the wear-resistant layer 10 and the waterproof layer 8 by using a hot melt method, and the foam plastic, polyethylene and polyvinyl chloride are placed together respectively, and then hot-pressed at a certain temperature and pressure to combine them together. The good waterproof properties of polyethylene and polyvinyl chloride can effectively prevent moisture from penetrating into the surface or underground structure under the geotextile, thereby playing a role in waterproofing and anti-penetration. The anti-cracking layer 9 polyurethane connected by the internal combination has good toughness and elasticity. Therefore, adding polyurethane can increase the flexibility of the geotextile, making it more resistant to stretching and tearing.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
