Production process of steel pipe pile for bridge applicable to marine environment

Abstract

The invention provides a production process of a steel pipe pile for a bridge applicable to the marine environment. The production process of the steel pipe pile for the bridge applicable to the marine environment comprises the following steps of S1, preparing polyether-ether-ketone anti-corrosion wear-resistant emulsion; S2, adopting the steel pipe pile, heating the steel pipe pile by utilizing aquenching furnace, and derusting a rear surface by sandblast, wherein the temperature range of heating ranges from 800 to 850 DEG C; S3, spraying or roll-coating the polyether-ether-ketone anti-corrosion wear-resistant emulsion prepared in the S1 to the surface of the steel pipe pile treated through the S2, and high-temperature baking at 400 DEG C to form a film after surface drying, wherein thebaking duration time ranges from 1 to 2h; and after spraying the polyether-ether-ketone anti-corrosion wear-resistant emulsion to a connector part of the steel pipe pile, treating by adopting medium frequency heating or infrared heating. The composite steel pipe pile prepared through the process can last for 15000h in a neutral salt spray resistance test, and has super-long-acting chemical corrosion resistance and wear resistance. The wear-resistant bearing capacity of the steel pipe pile is effectively improved, meanwhile, the service life of the steel pipe pile is prolonged, and the servicelives of a large-scale sea-crossing bridge, a tunnel and a building are effectively guaranteed.

Description

technical field [0001] The invention relates to the field of anti-corrosion materials, and more specifically relates to a production process of steel pipe piles for bridges suitable for marine engineering environments. Background technique [0002] At present, due to the influence of the marine environment in which large-scale sea-crossing bridges are located, and the subsequent bridge deck is affected by vehicle vibration, friction, rain and snow ablation on the bridge deck, salt spraying and snow removal construction, etc., the corrosion resistance and wear resistance are poor. security risks. Among them, steel pipe piles used in large quantities are also subject to corrosion due to the complexity of the environment, which is difficult to overcome. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a production process for steel pipe piles for bridges suitable for marine environments, and to...
