High-strength earth work grille net

Abstract

A high-strength earth work grille net is characterized in that the grille net is waved by the high-strength high-modulus northylen. The grille net is weaved by a plurality of high-strength high-modulus polythene cords. Each cord comprises a plurality of folds, and each fold comprises a plurality of threads. Each lattice of the grille net is quadrangle. The outer layer of the grille net is coated with art glue. The grille net of the invention has the advantages of remarkably high tensile strength, high corrosion resistance, high wearing resistance, low specific elongation, less creep deformation, stronger locking and engaging function to the soil body, effectively processing the soft earth base and the steep bank, restricting the lateral displacement of the soil body, overcoming the differential descending of the soil body, greatly increasing the bearing capacity of the ground work and increasing the whole capability of the ground work.

Description

technical field [0001] The invention relates to a geogrid net used in foundation construction processes such as roads, railways, water conservancy, hydropower, dam reclamation, flood control and the like. Background technique [0002] Advanced non-metallic composite materials have been developing vigorously in the past ten years. Especially in developed countries, the application of advanced new fiber materials and their composite technology is regarded as a major industry for the development of high-tech new materials. Since the 1990s, they have been widely used in aviation, Aerospace, military equipment, sports equipment and civil engineering fields such as bridges, tunnels, and building reinforcement. At present, there are three types of fibers used in known composite materials: First, carbon fiber sheets are widely used. Carbon fibers have excellent mechanical properties and high modulus advantages, and are widely used in the fields of aviation, aerospace and structural ...

AI Technical Summary

Problems solved by technology

However, there is also a fly in the ointment, such as fear of water damage and light exposure. The strength of the aramid sheet is greatly reduced after being soaked in water and exposed to light, so it is not suitable for applications in the field of water and long-term light.

3. Glass fiber cloth, the strength of glass fiber is only one-third of that of aramid fiber, and one-fifth of that of high-strength polyethylene fiber. It has low mechanical properties, and it is rigid, easy to break, difficult to construct, and not resistant to acid and alkali. Anti-ultraviolet light, only suitable for filling materials in low-grade composite materials

However, the grid mesh made of metal is easy to deform, it is not easy to recover after deformation, the folding volume is large, the storage and transportation are extremely inconvenient, and there are many difficult problems in terms of tensile strength, corrosion resistance and anti-microbial.
