Description

Technical Field

[0001] This utility model belongs to the field of building materials technology, specifically a tensile-resistant composite geomembrane. Background Technology

[0002] Ordinary geomembranes use plastic films as the impermeable base material. High-molecular-weight chemical flexible materials such as polyvinyl chloride (PVC), polyethylene (PE), and ethylene / vinyl acetate copolymer (EVA) are commonly used plastic films. They rely on their impermeability to block water leakage channels in earthen dams, and can withstand water pressure and adapt to dam deformation with their high tensile strength and elongation. However, ordinary geomembranes have the problem of limited tensile strength. In complex engineering environments or when subjected to large tensile forces, they are easily stretched, deformed, or even torn, affecting their impermeability and other performance characteristics.

[0003] Meanwhile, a composite geomembrane, disclosed in announcement number CN202482828U, includes a geomembrane body, wherein multiple resin strips are arranged on at least one surface of the geomembrane body, capable of embedding into the medium surrounding the composite geomembrane. When this composite geomembrane is used as a waterproof and seepage-proof layer in various engineering projects, the composite geomembrane is subjected to pressure from the overlying fill material, and the multiple resin strips arranged on at least one surface of the geomembrane body are respectively embedded into the medium surrounding the composite geomembrane.

[0004] The aforementioned composite geomembrane can only improve the stability of the composite geomembrane in engineering projects, preventing slope slippage. However, it cannot improve the tensile strength of the composite geomembrane or prevent deformation or tearing during the stretching process, thus increasing the need for maintenance and upkeep during use.

[0005] Therefore, a tensile-resistant composite geomembrane is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a tensile-resistant composite geomembrane, which enables the composite geomembrane to achieve excellent tensile and tear resistance. Not only is the tensile strength significantly improved, but the composite geomembrane is also not easily stretched, deformed, or torn, and it also reduces the maintenance work of the project.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tensile-resistant composite geomembrane, comprising a flame-retardant layer fixedly provided on the upper end face of the composite geomembrane body, fixing plates fixedly provided on both the front and rear sides of the flame-retardant layer, a nylon rope fixedly provided in the middle of the inner side of the fixing plate, a glass fiber board fixedly provided on the upper inner side of the fixing plate, an impermeable layer fixedly provided on the upper end face of the glass fiber board, and a fixed elongated body fixedly provided on the left and right sides of the upper end face of the impermeable layer, and a tough plate fixedly provided on the inner side of the fixed elongated body, and two tough plates are provided.

[0008] Preferably, concave fixing blocks are fixed around the perimeter of the impermeable layer, and the lower end of the concave fixing blocks is fixed to the lower end of the composite geomembrane body.

[0009] By adopting the above technical solution, the concave fixing block can prevent displacement during stretching.

[0010] Preferably, a second support block is fixedly provided at the middle front end of the seepage-proof layer, and a first support block is fixedly provided at the rear end of the seepage-proof layer.

[0011] By adopting the above technical solution, the device can be fixed using a support block.

[0012] Preferably, a sun-protective layer is fixedly provided on the lower end face of the concave fixing block, and a flexible plate is fixedly provided on the inner side of the concave fixing block.

[0013] By adopting the above technical solution, the surface of the composite geomembrane can be protected by a sun-protective layer, increasing its service life.

[0014] Preferably, rectangular plates are fixed on both the left and right sides of the upper end face of the flame-retardant layer, and the upper side of the rectangular plates is fixed to the lower side of the fiberglass board.

[0015] By adopting the above technical solution, the tensile effect can be enhanced by using glass fiber.

[0016] Preferably, a rubber plate is fixedly installed on the upper end surface of the second support block, and the lower side of the rubber plate is fixed to the upper end of the first support block.

[0017] By adopting the above technical solution, the rubber sheet can prevent the impermeable layer from being punctured.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model utilizes nylon ropes, fiberglass boards, and fixed long and tough plates to enable the composite geomembrane to achieve excellent tensile and tear resistance. Not only is the tensile strength significantly improved, but the composite geomembrane will not be easily stretched, deformed, or torn, thus reducing the maintenance work of the project.

[0020] 2. This utility model uses a sun-protective layer and concave fixing blocks to prevent the surface of the composite geomembrane from being directly exposed to ultraviolet rays. Over time, this can lead to a shortened lifespan of the composite geomembrane and frequent maintenance. Attached Figure Description
