High-strength reinforced belt and manufacturing method thereof

Abstract

The invention relates to a high-strength reinforced belt and a manufacturing method thereof. The high-strength reinforced belt comprises multiple radial bundled rigid yarn, multiple weft polypropylenefilament yarn and radial side yarn; the radial bundled rigid yarn is arranged in parallel, the radial side yarn is arranged on the two sides of the radial bundled rigid yarn, during weaving, the radial bundled rigid yarn and the weft polypropylene filament yarn are Iinterspersed in a crisscross manner to form a reticulate body, two ends of the weft polypropylene filament yarn are fixedly connected with the radial side yarn, the radial bundled rigid yar comprises, by mass percent, 88 to 94% of polypropylene, 5 to 10% of polyethylene, 0.5 to 1% of a plastic antiaging agent and 0.5 to 1% of a plastic reinfocer. Through melting, stirring and extrusion forming, the radial bundled rigid yarn is obtained; the radial bundled rigid yarn is obtained through a mixture of polypropylene and polyethylene, the strength of the radial bundled rigid yarn can be effectively improved, and meanwhile, density of the radial bundled rigid yarn is reduced, and the proportion is low.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a high-strength reinforced belt and a manufacturing method thereof. Background technique [0002] In the construction of subgrades, embankments, retaining walls with reinforced reinforcement for slope protection, soft soil foundations, etc., in order to ensure the quality of the project, reinforcement materials are often used in the soil, and the friction with the soil is used to transfer the force to Reinforced materials form the filling of structures such as reinforced soil lattice walls, reinforced soil subgrades, reinforced soil abutments, and reinforced soil cushions. Reinforced tape is a commonly used reinforced material. Most of the existing reinforced tapes have a nominal width of 5cm (gram weight 52g / m), a breaking force greater than 20000N, or a nominal width of 7cm (gram weight 80g / m), Reinforced belts with a breaking tensile force greater than 25000N; with ...

AI Technical Summary

Problems solved by technology

[0008] Although the processing efficiency of the overlapping rib sewing method is much higher than that of the parallel double rib sewing method, its processing efficiency is still reduced by 30% compared with the single rib row, and the processing cost will increase accordingly.

And because there is a difference in the flatness of the two reinforced belts, and the thickness is thicker after overlapping, the sewing machine will also have skipped stitches and thread throwing when the worker is sewing, which will affect the quality of the entire row.

And through a large number of test experiments, we found that the double-folded ribs cannot be fully synchronized during the process of stress because the two ribs cannot be completely overlapped when sewing. In this case, its actual stress The force value can only reach about 90% of the theoretical value, and in mass production, this 90% value may not be guaranteed, and then it cannot reach the ideal state of 1+1≥2 originally envisioned by the designer.
