Description

Technical Field

[0001] This utility model relates to the field of grid technology, and in particular to a fiber-plastic bundled grid. Background Technology

[0002] Fiber-plastic bundled geogrid is a high-performance geosynthetic material, primarily formed by bundling high-strength, high-toughness, and high-molecular-modulus polyester yarns together and then covering them with a PE protective layer. This geogrid offers advantages such as high strength, stability, miniaturization, and economy. It can withstand extremely high loads while maintaining long-term stability without significant creep deformation. Under 70% ultimate strength load, the geogrid exhibits less than 1% creep deformation over 114 years, demonstrating its excellent strength and stability. Compared to traditional polypropylene and polyethylene geogrids, fiber-plastic bundled geogrids exhibit significantly less creep deformation, helping to better control post-construction deformation of embankments and structures. Furthermore, by using this geogrid, the pile spacing can be increased from 2.0m to 3.0m, thereby reducing the number of piles used by 50% and reducing overall costs by 30%-40%. This not only improves construction efficiency but also shortens the construction cycle to approximately half of the original time.

[0003] The problem with the existing technology is that after the polyester yarn of the fiber plastic grid is bundled into strands and covered with a PE protective layer, the contact area between the inner wall of the PE protective layer and the bundled polyester yarn strands is small, which will cause the strands to separate from the protective layer and affect subsequent use.

The transverse grid and the longitudinal grid are intersected to form the polyester yarn fiber-plastic grid. Each grid bar includes a PE wrapping layer and a polyester yarn bundle wrapped on its inner wall. The outer wall of the polyester yarn bundle is wound with tightening wires. Multiple tightening wires are provided and distributed in a vertical array on the outer wall of the polyester yarn bundle. Adjacent tightening wires are fixedly connected by a series wire bundle.

[0007] Preferably, a reinforcing rib is fixedly connected to the outer wall of the serial wire harness, and the outer wall of the reinforcing rib is provided with a groove.

[0014] 2. This type of fiber-reinforced bundled grid increases the contact area with epoxy resin by creating grooves on the outer wall of the reinforcing ribs and wrapping them with a PE coating layer, thereby improving stability. Attached Figure Description
