Description

Technical Field

[0001] This utility model relates to the field of geotextile technology, specifically to a reinforced crack-resistant geotextile. Background Technology

[0002] Geotextile, also known as geotextile fabric, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile is one type of new geosynthetic material; the finished product is cloth-like, generally 4-6 meters wide and 50-100 meters long. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles. As a key material in modern engineering, geotextiles play an irreplaceable role in civil engineering, water conservancy, transportation, and other fields due to their multifunctionality (such as isolation, filtration, and reinforcement) and adaptability (corrosion resistance and permeability). With the development of composite technology, its application scenarios continue to expand. However, during installation, workers need to hold one end while laying the geotextile, which is relatively labor-intensive.

[0003] As disclosed in application number CN202122151235.9, this utility model discloses a reinforced crack-resistant geotextile, comprising a geotextile body, a base layer, a reinforcing layer fixedly connected to the surface of the base layer, a crack-resistant layer fixedly connected to the surface of the reinforcing layer, a corrosion-resistant layer fixedly connected to the surface of the crack-resistant layer, an insulation layer fixedly connected to the surface of the corrosion-resistant layer, a flame-retardant layer fixedly connected to the surface of the insulation layer, a waterproof layer fixedly connected to the surface of the flame-retardant layer, and a functional layer fixedly connected to the surface of the waterproof layer. This utility model, through the combined use of the geotextile body, base layer, reinforcing layer, crack-resistant layer, corrosion-resistant layer, insulation layer, flame-retardant layer, waterproof layer, functional layer, elastic layer, wrinkle-resistant layer, and wear-resistant layer, solves the problems of existing commonly used geotextiles having a simple structure, low tensile strength and deformation resistance, and poor corrosion resistance, waterproofing, flame retardancy, and insulation effects, thus reducing the service life and practicality of the geotextile.

[0004] The above applications currently have the following shortcomings:

[0005] During the laying process, one end needs to be held by manpower. If no manpower is available to hold it, the laying process will shift, affecting the efficiency of the laying work.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a reinforced crack-resistant geotextile in order to achieve a more practical value. Utility Model Content

[0007] The purpose of this invention is to provide a reinforced crack-resistant geotextile to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a reinforced crack-resistant geotextile, comprising a waterproof membrane layer and a heat-insulating cotton layer, characterized in that a geotextile base layer is disposed below the waterproof membrane layer, and a connecting strip is provided at the right end of the geotextile base layer, and a positioning ring is provided at the end of the connecting strip, a synthetic fiber layer is disposed inside the geotextile base layer, and the heat-insulating cotton layer is disposed below the synthetic fiber layer.

[0009] Furthermore, a geotextile subbase is placed below the insulation cotton layer, and the shape and structure of the geotextile subbase match the shape and structure of the geotextile base layer.

[0010] Furthermore, a vertical braided strip is disposed above the synthetic fiber layer, and a horizontal braided strip is threaded through the interior of the vertical braided strip.

[0011] Furthermore, the vertical and horizontal braided strips are arranged in a cross shape, and an internal cavity is provided between the vertical and horizontal braided strips.

[0012] Furthermore, the digital class sign display screen is equipped with a movable cover plate at its upper end, and a fiber layer is placed above the vertical and horizontal woven strips of the handle fixed on the surface of the movable cover plate, and the fiber layer is tightly attached to the geotextile base layer.

[0013] Furthermore, friction balls are placed on the bottom surface of the geotextile base layer, and the friction balls are symmetrically distributed about the center of the geotextile base layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model significantly enhances the waterproof performance of the geotextile base layer by adding a waterproof membrane layer. Geotextile itself does not possess waterproofing capabilities, but by combining it with a waterproof membrane, it effectively prevents water penetration. The composite structure of the waterproof membrane layer and the geotextile base layer not only enhances the overall strength of the material but also improves its tensile and erosion resistance, preventing cracking. The positioning ring facilitates positioning at one end of the geotextile base layer, making it convenient for workers to lay the geotextile and effectively preventing its movement. The vertical and horizontal woven strips form an internal cavity that can store anti-corrosion materials, extending the geotextile's service life. The insulation layer has waterproof and moisture-proof properties, protecting the geotextile from moisture and extending its service life. The synthetic fiber layer, such as polypropylene, polyester, and nylon, has high initial strength and, after weaving, forms a regular interwoven structure, further improving the geotextile's load-bearing capacity. The synthetic fiber layer typically has good resistance to acids, alkalis, insects, and mold, maintaining its original properties in various harsh environments. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figures 1-4 As shown, it includes a waterproof membrane layer 1 and a heat insulation cotton layer 11. The feature is that a geotextile base layer 2 is placed below the waterproof membrane layer 1, and a connecting strip 3 is provided at the right end of the geotextile base layer 2. A positioning ring 4 is provided at the end of the connecting strip 3. A synthetic fiber layer 10 is placed inside the geotextile base layer 2, and the heat insulation cotton layer 11 is placed below the synthetic fiber layer 10.

[0025] In summary: the positioning ring 4 facilitates the positioning of one end of the geotextile base layer 2, making it convenient for workers to lay the geotextile and effectively preventing it from shifting. The insulation layer 11 has waterproof and moisture-proof properties, protecting the geotextile from moisture and extending its service life. The synthetic fiber layer 10, such as polypropylene, polyester, and nylon, has high original strength and forms a regular interwoven structure after weaving, further improving the load-bearing capacity of the geotextile. The synthetic fiber layer 10 usually has good resistance to acids, alkalis, insects, and mildew, and can maintain its original properties in various harsh environments.

[0026] like Figures 1-4As shown, a geotextile base layer 12 is placed below the insulation cotton layer 11, and the shape and structure of the geotextile base layer 12 match the shape and structure of the geotextile base layer 2. A vertical woven strip 7 is placed above the synthetic fiber layer 10, and a horizontal woven strip 8 is inserted inside the vertical woven strip 7. The vertical woven strip 7 and the horizontal woven strip 8 are arranged in a cross shape, and an internal cavity 9 is placed between the vertical woven strip 7 and the horizontal woven strip 8. A movable cover plate is placed at the top of the digital class sign display screen, and a handle is fixed on the surface of the movable cover plate. A fiber layer 6 is placed above the vertical woven strip 7 and the horizontal woven strip 8, and the fiber layer 6 is tightly attached to the geotextile base layer 2. Friction balls 5 are placed on the bottom surface of the geotextile base layer 2, and the friction balls 5 are symmetrically distributed about the center of the geotextile base layer 2.

[0027] In summary, the addition of the waterproof membrane layer 1 significantly enhances the waterproof performance of the geotextile base layer 2. While geotextile itself does not possess waterproofing capabilities, its combination with the waterproof membrane effectively prevents water penetration. The composite structure of the waterproof membrane layer 1 and the geotextile base layer 2 not only strengthens the overall material but also improves its tensile and erosion resistance, preventing cracking. The vertical braided strips 7 and horizontal braided strips 8 form an internal cavity 9, which can store anti-corrosion materials, extending the service life of the geotextile.

[0028] Working principle: When this type of reinforced crack-resistant geotextile is used, it first... Figures 1-4 During installation, the geotextile base layer 2 is laid on the bottom surface, and the positioning bolt is passed through the positioning ring 4 to position one end of the geotextile base layer 2. After positioning, the other end of the geotextile base layer 2 is pulled to lay it flat. The friction ball 5 can prevent the geotextile base layer 2 from sliding. The heat insulation cotton layer 11 has waterproof and moisture-proof properties, which can protect the geotextile from moisture and extend its service life. The synthetic fiber layer 10, such as polypropylene, polyester, nylon, etc., has high original strength. After being woven, it forms a regular interwoven structure, which further improves the load-bearing capacity of the geotextile. The synthetic fiber layer 10 usually has good acid resistance, alkali resistance, insect resistance and mildew resistance, and can maintain its original properties in various harsh environments. The addition of the waterproof membrane layer 1 significantly enhances the waterproof performance of the geotextile base layer 2. Geotextile itself does not have waterproof function, but by combining it with a waterproof membrane, it can effectively prevent water penetration. The composite structure of the waterproof membrane layer 1 and the geotextile base layer 2 not only enhances the overall strength of the material, but also improves its tensile and erosion resistance, preventing cracks. The vertical woven strips 7 and the horizontal woven strips 8 form an internal cavity 9, which can store anti-corrosion materials and extend the service life of the geotextile.
