Description

Technical Field

[0001] The utility model belongs to the technical field of geotechnical materials for water conservancy projects, and more specifically, relates to a tensile-resistant and anti-seepage soil composite cloth. Background Technique

[0002] Due to the advantages of light weight, good flexibility, high strength, strong integrity and not easy to rot, geotechnical materials have functions such as filtration, drainage, isolation, reinforcement and anti-seepage in engineering, which can improve the engineering quality. Therefore, they are widely used in engineering fields such as water conservancy, water transportation, highways, and buildings. At present, however, there are problems with geotechnical anti-seepage materials such as low tensile strength, weak puncture resistance, poor resistance to high-speed water flow scouring, poor soil retention, poor anti-seepage ability, and short service life, which cannot meet the high demand for anti-seepage geotextiles in various projects.

[0003] For example, a kind of anti-seepage composite geotextile with the patent application number CN202020595912.9 includes: a composite fiber layer and first geotextile layers respectively arranged on the upper and lower layers of the composite fiber layer. The composite fiber layer and the two first geotextile layers are sewn together by polyester fiber threads; the composite fiber layer includes a polyethylene terephthalate fiber layer, a second geotextile layer and a polypropylene fiber layer arranged in sequence, and the polyethylene terephthalate fiber layer, the second geotextile layer and the polypropylene fiber layer are fixed by sewing threads. The anti-seepage composite geotextile of the utility model has good adaptability to deformation, high puncture strength and high cylindrical strength, and its characteristics such as high tensile strength, high tear strength and high resistance to high-speed water flow scouring, thereby improving the soil retention performance of geotechnical materials; and its water permeability coefficient is small, so it has excellent anti-seepage and waterproof properties, and at the same time also has excellent impact resistance and acid and alkali resistance.

[0004] Although the above-mentioned anti-seepage composite geotextile can improve the soil retention performance of geotechnical materials; and its water permeability coefficient is small, its tensile resistance ability is still poor. Content of the Utility Model

[0005] The utility model provides a tensile-resistant and anti-seepage soil composite cloth to solve the above technical problems and improve the tensile resistance ability.

[0006] A tensile-resistant and anti-seepage soil composite cloth of the utility model includes a nylon outer cloth; the number of the nylon outer cloth is two layers; the two layers of nylon outer cloth are respectively fixedly connected to a polyester waterproof cloth; it also includes a polyester fiber layer slidably arranged inside the polyester waterproof cloth; each pair of adjacent polyester waterproof cloth and polyester fiber layer are fixedly connected by high-elastic sponge; a bacteriostatic layer is fixedly connected to the inner side of each layer of polyester fiber layer; a plurality of buffer balls are pressed between the two bacteriostatic layers; the plurality of buffer balls are fixedly connected by a tensile-resistant layer; the outer edge of the tensile-resistant layer is fixedly connected to an adhesive layer; hot melt adhesives are arranged on the upper and lower end faces of the adhesive layer.

[0007] Preferably, the nylon outer cloth is made of nylon material; the thickness of the nylon outer cloth is 10-15 mm.

[0008] Preferably, the bacteria isolation layer is a blended silver ion bamboo charcoal cotton fabric; the bacteria isolation layer is grooved at multiple buffer ball positions to snap-fit the buffer balls.

[0009] Preferably, the buffer balls are made of high-elastic heat-resistant rubber material.

[0010] Preferably, the anti-tensile layer is made of high-elastic rubber material.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By providing a high-elastic sponge, the gap between the high-elastic sponge and the lower end surface of the inner side of the polyester waterproof cloth and the upper end surface of the inner side of the polyester fiber layer provides space for the deformation of the high-elastic sponge, preventing the pressure from directly acting on the nylon outer cloth, the polyester waterproof cloth, and the polyester fiber layer and causing surface damage, and improving the anti-tensile performance; by providing buffer balls, the pressure received during use is further buffered; by providing an anti-tensile layer, the anti-tensile layer is fixedly connected to the buffer balls. During the stretching process, first, the high-elastic sponge deforms for buffering, and at the same time, by using the deformation of the buffer balls, the surface of the anti-tensile layer close to the two bacteria isolation layers is further improved in anti-tensile performance.

[0016] Specific Embodiment 1: Please refer to Figure 1-2An anti-tensile and anti-seepage soil composite cloth, comprising a nylon outer cloth 10; the number of the nylon outer cloth 10 is two layers; the two layers of the nylon outer cloth 10 are respectively fixedly connected to a polyester waterproof cloth 11; it further comprises a polyester fiber layer 13 slidably arranged inside the polyester waterproof cloth 11; each pair of adjacent polyester waterproof cloth 11 and polyester fiber layer 13 are fixedly connected by a high-elastic sponge 12; the inner side of each layer of the polyester fiber layer 13 is fixedly connected to an antibacterial layer 14; a plurality of buffer balls 16 are pressed between the two layers of the antibacterial layer 14; the plurality of buffer balls 16 are fixedly connected by an anti-tensile layer 17; the outer edge of the anti-tensile layer 17 is fixedly connected to an adhesive layer 15; hot melt adhesives are arranged on the upper and lower end faces of the adhesive layer 15; the nylon outer cloth 10 is made of nylon; the thickness of the nylon outer cloth 10 is 10-15 mm; the antibacterial layer 14 is a blended silver ion bamboo charcoal cotton fabric; the antibacterial layer 14 is grooved at positions corresponding to the plurality of buffer balls 16 to snap the buffer balls 16; the buffer balls 16 are made of high-elastic heat-resistant rubber; the anti-tensile layer 17 is made of high-elastic rubber; by arranging the high-elastic sponge 12, the gap between the high-elastic sponge 12 and the lower end face inside the polyester waterproof cloth 11 and the upper end face inside the polyester fiber layer 13 provides space for the deformation of the high-elastic sponge 12, preventing the pressure from directly acting on the nylon outer cloth 10, polyester waterproof cloth 11, and polyester fiber layer 13 and causing damage to their surfaces, and improving the anti-tensile performance; by arranging the buffer balls 16, the pressure received during use is further buffered; by arranging the anti-tensile layer 17, the anti-tensile layer 17 is fixedly connected to the buffer balls 16, and during the stretching process, first the high-elastic sponge 12 deforms for buffering, and at the same time, by using the deformation of the buffer balls 16, the surface of the anti-tensile layer 17 close to the two antibacterial layers 14 is used to further improve the anti-tensile performance.

[0017] During operation, it is laid on the construction surface; when the soil layer on the construction surface is loose, the nylon outer cloth 10 first intercepts the dust for the first time. As the soil blocks or the stones in the soil blocks continuously roll over the surface of the nylon outer cloth 10, the polyester waterproof cloth 11 conducts the pressure received by the nylon outer cloth 10, and the high-elastic sponge 12 is used for preliminary absorption and torsion. At the same time, the gap between the high-elastic sponge 12 and the lower end face inside the polyester waterproof cloth 11 and the upper end face inside the polyester fiber layer 13 provides space for the deformation of the high-elastic sponge 12, preventing the pressure from directly acting on the nylon outer cloth 10, polyester waterproof cloth 11, and polyester fiber layer 13 and causing damage to their surfaces; when bacteria and microorganisms in the construction surface enter the inside, they are blocked by the antibacterial layer 14 and will not continue to damage the internal structure; when a huge pressure or tensile force acts on the surface of the nylon outer cloth 10, the deformation of the buffer balls 16 is used to further absorb the pressure or shear force. At the same time, the anti-tensile layer 17 starts to deform and wraps around the inner and outer sides of the two anti-tensile layers 17 to support other cloth layers, preventing the surfaces of the nylon outer cloth 10, polyester waterproof cloth 11, polyester fiber layer 13, and antibacterial layer 14 from being easily damaged due to lack of support after being stretched by a large force.
