On-site anti-corrosion treatment method for steel pipe piles for wharves

Abstract

The invention discloses an on-site preservative treatment method for a steel pipe pile for a wharf and belongs to the technical field of knife coating preservative treatment. The on-site preservative treatment method for the steel pipe pile for the wharf includes steps that I, construction preparation; II, appearance inspection for steel pipe joints; III, shot blasting; IV, surface dust extraction; V, coating preparation; VI, coating paving; VII, knife coating; VIII, knife coating appearance inspection; IX, drying film thickness detection; X, sampling inspection for adhesive force; XI, steel pipe joint acceptance check. Compared with the prior art, the on-site preservative treatment method for the steel pipe pile for the wharf saves the intermediate conveying cost of the steel pipe pile and comprehensively and effectively monitors the splicing and preservative process of the steel pipe pile through reasonable construction technology process; the one coat epoxy heavy anti-corrosive coating is high in curing characteristic, fast in drying speed and large in viscosity, the proportion of volatile ingredient arrives at 95%, and the coating mix proportion is controlled under the temperatures of different time periods; the quality defect rate is lowered, the material is saved, the working efficiency is improved, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of scraping coating anticorrosion treatment, and in particular relates to an anticorrosion treatment method for wharf steel pipe piles. Background technique [0002] With the development of domestic and foreign shipping industry, large-diameter steel pipe piles are constantly being applied to the construction of wharfs. The steel pipe piles used are assembled from steel pipe joints. Anti-corrosion treatment for steel pipe joints. At present, the anti-corrosion treatment of steel pipe joints is carried out in the factory workshop, and then the steel pipe joints are assembled into a whole pile. One of the anti-corrosion treatment methods is the spraying coating process. The appearance of the sprayed paint film is relatively uniform, the efficiency is high, the viscosity of the paint is low, and the curing time is short. ; The other is the machine scraping process, which has high viscosity, short curing time, ...

Problems solved by technology

At present, the anti-corrosion treatment of steel pipe joints is carried out in the factory workshop, and then the steel pipe joints are assembled into a whole pile. One of the anti-corrosion treatment methods is the spraying coating process. The appearance of the sprayed paint film is relatively uniform, the efficiency is high, the viscosity of the paint is low, and the curing time is short. The other is the machine scraping process, which has high viscosity, short curing time, and high efficiency of the coating process, which is suitable for mass production in factories. The two anti-corrosion treatment processes are expensive and difficult to fully and effectively assemble steel pipe piles. , The whole process of anti-corrosion is monitored, the scraping quality of steel pipe piles is seriously defective, the quality of scraping coating cannot be guaranteed, and the corrosion speed of steel pipe piles is fast, which in turn affects the quality of the wharf
