Abstract

The invention discloses a manufacturing technology of a high-speed railway track plate. The manufacturing technology of the high-speed railway track plate comprises the steps of high-speed railway track plate reinforced bar prefabrication, high-speed railway track plate concrete prefabrication, pouring manufacture of the high-speed railway track plate, maintenance and treatment of high-speed railway track plate concrete and high-speed railway track plate finished products. The track plate has the advantages of high seismic resistance strength, good weather resistance, long service life, good internal compactness, excellent anti-freezing property, excellent anti-cracking property and the like. The influence of electromagnetic induction caused by using metal materials in the operation process of high-speed railway or urban track transit is avoided, so that the communication security of high-speed railway or urban track transit is improved.

Description

technical field [0001] The invention relates to a manufacturing process of a track slab, in particular to a manufacturing process of a high-speed rail track slab. Background technique [0002] Fiber-reinforced matrix composites were first developed in the United States in the 1930s. At that time, composite products were mainly to meet the needs of military and aerospace fields. In recent years, based on the many advantages of fiber thermoplastic composite materials, people began to shift the research focus to fiber reinforced thermoplastic or / and thermosetting composite materials, and began to conduct continuous and in-depth research on this type of material. The output of fiber thermoplastic composite materials has gradually increased. It has been applied in many fields, such as aerospace, military industry, automobiles, electronic appliances, bridge building reinforcement, yachts and ships, etc. [0003] Compared with thermoplastic resins, thermosetting resins have many a...
