Description
Technical field
The utility model relates to offshore platforms more particularly to a kind of for the close of offshore platform deck supporting leg
Seal anti-corrosive apparatus.Belong to Offshore Engineering field of steel structure.
Background technique
Currently, the offshore platform of 10,000 tons mostly uses " floating support method " to carry out Attention problems, and offshore platform
Deck supporting leg (DSU) is essential device in " floating support method ".In offshore platform land formation, deck supporting leg
It is mounted between piston shoes and offshore platform, to the connection between piston shoes and offshore platform and supports ocean stone
Oily platform.During offshore platform floating support, the essence of " floating support method " installation be exactly by the supporting point of offshore platform,
Offshore platform is slowly transferred on permanent structure from temporary structure, then, then by each bearing diagonal of deck supporting leg
Lacing wire cutting, to complete platform weight transfer.
The mounting technique of existing offshore platform " floating support method ", usually by offshore platform deck supporting leg with
The bearing diagonal lacing wire root of offshore platform platform connection carries out gas flame cuttiug operation using flame cutting gun.Support lacing wire cutting
After the completion, the oval-shaped support foot position that offshore platform bottom is connect with deck supporting leg, will be no any effectively anti-
It is exposed in wet air in the state of rotten measure；Therefore, on the one hand lead to the antifouling paint near cut point, in high temp fire
Under the baking effect of flame, by carburation by evaporation until destroying；On the other hand, this position due to being exposed to offshore platform bottom for a long time
On the sea in portion, under the influence of wave and surrounding sea areas moist air environment, the corrosion at the position will be accelerated.In order to guarantee this
It is imperative to reinforce anti-corrosion measure research at this for the anti-corrosion effect at place.
Utility model content
The main purpose of the utility model is to overcome disadvantages mentioned above of the existing technology, and provide a kind of offshore oil
The sealing corrosion device of platform deck supporting leg not only solves offshore platform bottom and offshore platform deck branch
The Anticorrosion of support leg junction；Moreover, substantially increasing offshore platform bottom and offshore platform deck supporting leg
The anti-corrosion effect and anticorrosive quality of junction.
The purpose of this utility model is realized by the following technical solutions:
The sealing corrosion device of a kind of offshore platform deck supporting leg, it is characterised in that: include: to be mounted on air zone
Sealing plate between cutting area, the Support being arranged in below cutting area, wherein air zone and sealing plate, cutting area and Support
It is arranged in straight line type, and forms the overall structure of a penetration type brace, and brace is installed on the upper surface of annular slab.
The outside of the air zone is round steel construction, and inside is confined space, and air zone is close to one end of mesa base
For elliptical openings form, and link together with mesa base region.
The sealing plate is round steel construction, and one section of closed air section is formed between sealing plate and mesa base, which exists
Land prefabrication phase is arranged in inside brace in advance.
The cutting area and Support are round steel construction, are connected between cutting area and Support, and in land precast oblique
The lacing wire stage completes.
The Support is round steel construction.
Load-carrying construction of the annular slab as support brace, the bottom in deck support leg structure.
The utility model has the beneficial effects that the utility model due to the adoption of the above technical scheme, not only solves ocean
The Anticorrosion of oil platform bottom and offshore platform deck supporting leg junction；Moreover, substantially increasing offshore oil
The anti-corrosion effect and anticorrosive quality of mesa base and offshore platform deck supporting leg junction.
