Abstract
The utility model discloses an anti-corrosion structure of a steel pipe pile with a marine engineering structure. The anti-corrosion structure comprises the steel pipe pile, wherein protection coating layers are coated on the surface of the upper part of the steel pipe pile along the circumferential direction; a concrete protection layer covers the surface of the middle part of the steel pipe pile along the circumferential direction; the surface of the lower part of the steel pipe pile are fixedly connected with sacrificial anodes. Due to a corrosion control system with a reasonable design, the anti-corrosion structure disclosed by the utility model perfectly protects the steel pipe pile from top to bottom, so that the influence of corrosion on the steel pipe pile is avoided, and the safety of the structure is guaranteed. Furthermore, at the expiration date of the control system, the control system can be repeatedly used, so that the service life of the steel pipe pile can be prolonged. The anti-corrosion structure is high in practicability; the whole structure is lower in cost and has an extremely good market prospect. The anti-corrosion structure of the steel pipe pile with the marine engineering structure can be widely applied to the marine engineering structures.
Description
Technical field
The utility model relates to marine structure corrosion control systems technology field, is specifically related to a kind of anti-corrosion structure of marine structure steel pipe pile.
Technical background
In marine structure, needing to widely apply steel pipe pile, steel pipe pile is basis and the key position of Oversea bridge, long piled wharf, offshore platform.Once steel pipe pile is corroded destruction, integrally-built safety will be had a strong impact on, and even causes the inefficacy of scrapping of structure, causes security incident.In current example; the long-term etch-proof problem of not comprehensive and systematic consideration steel pipe pile; for a certain section of steel pipe pile, protect for general; particularly not obvious for the anticorrosion ability in He Langjian district, Tidal zone; general coating can only guarantee the effect of 3-5; and reparation is substantially unrealistic again, the corrosion-resistant system of steel pipe pile integral body is not intactly set up.
Utility model content
The utility model is exactly for above-mentioned technical problem; a kind of anti-corrosion structure of marine structure steel pipe pile is provided; comprise steel pipe pile; it is characterized in that: the upper face of described steel pipe pile be circumferentially coated with protective coating; middle part surface be circumferentially coated with concrete cover, lower surface is fixedly connected with sacrificial anode.
Further, described sacrificial anode is fixedly welded on the both sides of steel pipe pile lower surface.
The beneficial effects of the utility model are: by the corrosion control system of appropriate design, steel pipe pile has been carried out to complete protection from top to bottom, avoided steel pipe pile to be corroded impact, guaranteed the safety of structure.And when this control system expires application life, also can repeated application, extend steel pipe pile application life.Practicality is good, and integrally-built cost is lower, has good market prospects, in marine structure, can find broad application.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Wherein, 1-steel pipe pile, 2-protective coating, 3-concrete cover, 4-sacrificial anode.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The anti-corrosion structure of marine structure steel pipe pile as shown in Figure 1, comprises steel pipe pile 1, the upper face of described steel pipe pile 1 be circumferentially coated with protective coating 2, middle part surface be circumferentially coated with concrete cover 3, lower surface is fixedly connected with sacrificial anode 4.
In technique scheme, described sacrificial anode 4 is fixedly welded on the both sides of steel pipe pile 1 lower surface.By protective coating 2, the Global Macros that 4 pairs of steel pipe piles of concrete cover 3 and sacrificial anode 1 carry out from top to bottom, integral body has formed complete anti-corrosion system.
Steel pipe pile 1 in the utility model, can be divided into ooze region from top to bottom, region under water, tidal range region, Lang Jian district and atmospheric region.Sacrificial anode 4 can adopt aluminium alloys, by in 4 pairs of steel pipe piles 1 of sacrificial anode in ooze region and under water the part in region carry out anticorrosion, sacrificial anode 4 is directly welded on steel pipe pile 1, guarantees at design lowest stage line below 1.5 meters, to guarantee antiseptic effect during welding.Concrete cover 3, by installation form, is arranged at the week of steel pipe pile 1 upwards after cast, contain resistance to erosion in concrete; anticracking; the material of resistance rust, is good maritime concrete, in 3 pairs of steel pipe piles 1 of concrete cover, in the part in He Langjian district, tidal range region, carries out anti-corrosion protection.Protective coating 2 is the good coating system of resistance to extra large work atmospheric environment, and the part in atmospheric region in steel pipe pile 1 is had to good protection effect.Of the present utility model simple in structure; cost is low, at reasonable consideration steel pipe pile 1 overall structure and environment of living in the situation that, for the residing varying environment of steel pipe pile 1 different piece, protect respectively; and the protection structure of each several part can not influence each other, and has greatly improved antiseptic effect.The utility model not only can be protected the steel pipe pile 1 of new installation, for in-service steel pipe pile 1, also can protect with reference to structure of the present utility model, has good practicality.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
