Technical Field

[0001] This utility model belongs to the field of geotechnical construction device technology, and specifically relates to a geotechnical seepage prevention device. Background Technology

[0002] The bottom seepage prevention of facilities such as landfills and hydraulic dams mainly uses geomembranes and other seepage prevention materials. However, existing geomembranes as seepage prevention materials have insufficient anti-aging ability and durability. Moreover, when the seepage prevention layer is damaged, it is often impossible to accurately locate the damage, which makes rapid repair difficult. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a geotechnical seepage prevention device.

[0004] This utility model is achieved through the following technical solution:

[0005] A geotextile seepage prevention device is characterized by comprising a warp-knitted grid, wherein the warp-knitted grid is woven from a plurality of longitudinal fabrics arranged in sequence and a plurality of transverse fabrics arranged in sequence, the transverse fabrics being woven together with optical fibers, and the surface of the transverse or longitudinal fabrics being sprayed with a polyurea resin layer.

[0006] The optical fiber is connected to the transverse fabric by a fastening wire at the bend.

[0007] The optical fiber is connected to the optical fiber sensor.

[0008] The longitudinal fabric surface is coated with a polyurea resin layer.

[0009] The optical fiber is a quartz optical fiber.

[0010] The beneficial effects of this utility model are: using a combination of warp-knitted grid and resin as a seepage barrier layer, it has higher anti-aging ability and durability, and optical fibers are embedded in the seepage barrier layer, so that when the seepage barrier layer is damaged, the damaged location can be quickly located and repaired.

[0015] The attached figure illustrates a specific embodiment of this utility model. This embodiment includes a warp-knitted grid 1, which is woven from a plurality of longitudinally arranged fabrics 2 and a plurality of transversely arranged fabrics 3. The transverse fabrics 3 are woven together with optical fibers 4. A polyurea resin layer 5 is sprayed onto the surface of either the transverse or longitudinal fabrics 2. Fastening wires 6 connect the optical fibers 4 to the transverse fabrics 3 at bends. The optical fibers 4 are connected to an optical fiber sensor 7. The longitudinal fabrics 2 are coated with a polyurea resin layer 5. The optical fibers 4 are quartz optical fibers.

[0016] The geotextile seepage prevention device of this invention consists of a warp-knitted grid 1 formed by weaving longitudinal fabric 2 and transverse fabric 3 arranged sequentially. An optical fiber 4 is embedded within the transverse fabric 3. The connection between the optical fiber 4 and the transverse fabric 3 is woven, and at the bends of the optical fiber 4, it is further secured to the transverse fabric 3 using fastening lines 6. The warp-knitted grid 1 with embedded optical fibers 4 is laid to the bottom of landfills, hydraulic dams, and other construction facilities for seepage prevention. During laying, the longitudinal fabric 2 faces upwards, and a polyurea resin layer 5 is sprayed onto the surface of the longitudinal fabric 2 to form a seepage prevention layer. During spraying, uniformity is ensured to guarantee the density and stability of the seepage prevention layer. The optical fiber 4 is connected to a light sensor 7 to establish a fiber optic sensing system, which allows for real-time monitoring of the seepage prevention layer. When damage occurs in the seepage prevention layer, the fiber optic sensing system will provide feedback information via fiber optic signals, thus determining the location of the damage. Fiber optic sensing uses optical fibers to sense and measure changes in physical quantities or the environment. It has advantages such as high sensitivity, strong anti-interference ability, and long transmission distance. It can monitor performance status in real time through various sensors and monitoring equipment, and promptly detect and warn of potential risks, thereby ensuring the safety and stability of the project.

[0017] The geotextile seepage prevention device of this invention improves seepage prevention performance: It employs an optical fiber 4 embedded in a warp-knitted grid 1, followed by a polyurea resin layer 5 sprayed onto it as the seepage prevention layer. Compared to traditional geomembranes and other seepage prevention materials, it exhibits higher anti-aging capabilities and durability, effectively improving the performance and stability of the seepage prevention layer. It allows for rapid and accurate damage location: when damage occurs in the seepage prevention layer, the optical fiber sensor 7 accurately detects the damage location and provides feedback information via optical fiber signals, enabling engineers to quickly locate the damage and achieve rapid repair, significantly improving project maintenance efficiency. It has wide applications: besides being used for seepage prevention at the bottom of landfills and hydraulic dams, it can also be widely applied in other civil engineering fields, such as buildings, roads, and bridges, demonstrating broad application prospects.
