Description
Technical field
The utility model relates to ocean platform construction technique field; be particularly related to a kind of steel pipe pile of platform; it is a kind of spud leg steel pipe of ocean platform with three layers of anticorrosive coat; be applicable to the anti-corrosion protection of ocean platform spud leg steel pipe pile, and be specially adapted to the repairing anticorrosion coating at labour ocean platform spud leg Tidal zone splash zone.
Background technology
At present, ocean platform has with the anticorrosion protection main method of spud leg steel pipe steel: coated with glass fibre reinforced plastics and anticorrosion coat protection.
Coated with glass fibre reinforced plastics has lightweight, the advantage that specific strength is high, heat-resisting, excellent corrosion resistance, the characteristics such as shock resistance is good, and workability is superior.But because the rigidity of glass fiber reinforced plastic is stronger, seawater can infiltrate the sheath inboard during with fiberglass sheath, after anti-corrosion protection effect, the fiber glass reinforced plastic cover that is difficult to reach satisfied leaked, because concrete erosion causes protecting the life-span reduction.
It is the way that generally adopts both at home and abroad that anticorrosion coat protects, and from mode of occupation for many years, the anticorrosion coat protection also exposes certain problem, the one, and the anticorrosion coat impact resistance is relatively poor, just needs to be serviced in the rear 1-2 of newly-built or maintenance; The 2nd, although had now can subaqueous construction anticorrosive paint, from the effect of the field, field repair is difficult to guarantee construction quality, does not reach the antiseptic effect of expection.
The utility model content
The purpose of this utility model is: a kind of spud leg steel pipe of ocean platform with three layers of anticorrosive coat is provided, can be applicable to the ocean platform spud leg repairing anticorrosion coating at the Tidal zone splash zone of labour, but have subaqueous construction, simple, the long characteristics of low, the anticorrosion guard time of surfacing requirement of construction.
The technical solution adopted in the utility model is: the ocean platform spud leg steel pipe with three layers of anticorrosive coat, comprise steel pipe, oil coating of the anticorrosion end of water proof, anticorrosion Cold winding band layer and anti-corrosive cover, it is characterized in that: scribble oil coating of the anticorrosion end of water proof at outer surface of steel tube, surface at oil coating of the anticorrosion end of water proof is tied with anticorrosion Cold winding band layer, outer surface cover at anticorrosion Cold winding band layer has anti-corrosive cover, and wherein nominal diameter of steel pipe is between 559~1355mm; The thickness of oil coating of the anticorrosion end of water proof is between 0.1~0.3mm; The thickness of anticorrosion Cold winding band layer is between 0.5~3mm, and when twining anticorrosion Cold winding band, lap width is between 55~70% between the anticorrosion Cold winding band; The thickness of anti-corrosive cover 4 is between 0.5~3mm.
The more excellent spud leg steel pipe of the ocean platform with three layers of anticorrosive coat is characterized in that: nominal diameter of steel pipe is 1004mm; The thickness of oil coating of the anticorrosion end of water proof is 0.2mm; The thickness of anticorrosion Cold winding band layer is 2mm, when twining anticorrosion Cold winding band, between the anticorrosion Cold winding band 60% of lap width; The thickness of anti-corrosive cover is 1.8mm.
Sketch the manufacturing process of spud leg steel pipe of the ocean platform with three layers of anticorrosive coat.Consult Fig. 1.Utilize instrument that steel pipe 1 is carried out surfacing, process to rustless, without surface irregularities, adhere to without other oxide and any halobios.External surface at steel pipe 1 applies oil of the anticorrosion end of water proof, forms water proof oil coating of the anticorrosion end 2, twines the cold anticorrosion belt that twines at oil coating of the anticorrosion end of water proof 2, forms anticorrosion Cold winding band layer 3.When twining anticorrosion Cold winding band, anticorrosion Cold winding band need overlap more than 55% up and down, then coat outer anti-corrosive cover 4, adopt and press take-up device that anti-corrosive cover 4 both sides are compressed along two axial flange of steel pipe pile, tighten with stainless steel bolt, and need the anti-corrosion of steel pipe pile cover to extrude oil of the anticorrosion end of water proof in two ends about in the of 4.
The beneficial effects of the utility model: the ocean platform spud leg steel pipe that the utlity model has three layers of anticorrosive coat, oil of the anticorrosion end of water proof has hydrophobicity performance, the anticorrosion Cold winding band in intermediate layer is the transition zone of oil of the anticorrosion end of bottom water proof and outer anti-corrosive cover, the anti-corrosion method of three-layer protection is convenient to subaqueous construction, require low to the steel pipe pile surfacing, easy construction, the protection time limit is long and can reduce halobiontic adhering to.Can be applicable to the ocean platform spud leg repairing anticorrosion coating at the Tidal zone splash zone of labour.
