▎ 摘  要

NOVELTY - Steel trestle anticorrosive material comprises 45-55 pts. wt. bisphenol A type epoxy resin, 25-35 pts. wt. alkyd resin, 15-25 pts. wt. light curing resin, 8-12 pts. wt. curing agent, 3-7 pts. wt. accelerator, 25-35 pts. wt. diluent, 1-3 pts. wt. pigment, 5-10 pts. wt. dispersing wetting agent, 2-4 pts. wt. thixotropic agent and 15-20 pts. wt. filler. The filler comprises modified graphene oxide, microcapsule filling and metal protection powder in a weight ratio of (1-3):(19-27):10. USE - The material is useful for steel pipe pile anti-corrosion in offshore steel trestle construction process. ADVANTAGE - The material: utilizes modified oxide graphene zinc powder as reinforcing material so as to improve the anti-impact strength of the antireflective coating; has the probability of reducing the anti-corrosion coating falling by ocean wave impact; improves the anti-corrosive coating to the steel protection effect; prolongs the service life of the steel pipe pile; utilizes the modified oxidation graphene that promotes resin curing on one hand; improves the impact resistance of the material; invades the seawater when the material on the surface of the pipe pile is impacted to generate fine cracks; oxidizes the metal protective powder to protect the pipe; increases the volume to repair the crack; and combines the micro-capsule filler with the oxidized and oxidized metal protective. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for constructing steel trestle anticorrosive material, comprising (1) constructing the steel trestle anticorrosive material by filling the soil and building the island, (2) performing the steel pipe column of anticorrosion treatment by using the anticorrosion material, forming anti-corrosion coating by anti-corrosion materials, and driving the steel pipe column in by hanging method according to the design position, (3) driving three steel pipe piles into each pier, using I-beams to connect the piles, using channel steel welding scissors to brace the steel pipe piles, and welding pad beam on the top of the piles to form whole, (4) fixing the spliced Bailey truss beam on the pad beam with U-shaped clips, (5) laying of bridge decks on two Bailey truss girders and installation of protective railings, and (6) performing the construction of the second span after the construction of the first span is completed, and repeating the operation until the construction of the steel trestle bridge is completed.
