The purpose of this invention is to provide a kind of being convenient to and make, safeguard that can guarantee is not again influencing under the oil tank ordinary production situation, change floating top of external floating top tank single-deck buoyancy module sectional type and method fast.
The object of the present invention is achieved like this, and the floating top of external floating top tank single-deck buoyancy module sectional type method connects into floating top edge buoyancy module or central removable buoyancy module by a plurality of fan-shaped plates, and annular buoyancy module is connected with single-deck again, and fan-shaped plate junction is provided with hermetically-sealed construction.
According to the floating top of method design-calculated external floating top tank single-deck buoyancy module sectional type, the floating top of external floating top tank single-deck buoyancy module sectional type, comprise floating top edge buoyancy module, single-deck and foam dam, it is characterized in that: floating top edge buoyancy module is connected by bolt arrangement with fan-shaped plate by fan-shaped plate and surrounds belt buoyancy module; Each quadrant of edge buoyancy module and annular slab connect into the cross section by bolt arrangement and are " h " shape, seal by ring seal between fan-shaped plate and the annular slab; Annular slab horizontal-extending to the inside is connected by bolt arrangement with single-deck.
Described single-deck can be to be connected as one by bolt arrangement by plate and plate, and the joint close face of plate and plate has face seal.
Be provided with radial seal between the described fan-shaped plate joint face.
Be welded with foam dam on the described floating top edge buoyancy module, soft seal is adopted in the gap between the foam dam on the floating top edge buoyancy module.
There is sealing gyratory intersection joint with annular slab between the described floating top edge buoyancy module.
Described single-deck central authorities connect central removable buoyancy module by bolt arrangement, and central removable buoyancy module is an integral type.
The removable buoyancy module in described middle part is to connect into belt buoyancy module by fan-shaped plate by bolt arrangement.
Described single-deck lower end can be connected with beam tube integrative-structure, and beam tube integrative-structure is to be connected with attaching parts by the cylindrical shell outside, and attaching parts is " fourth " word shape, and plane and plane, single-deck lower surface join on " fourth " shape, and last plane is connected by bolt arrangement with single-deck again.
Joint face has vertical connection side between described fan-shaped plate and the fan-shaped plate, between the vertical connection side radial seal is arranged, and is connected by bolt arrangement between the vertical connection side again.
Soft seal is adopted in gap between the foam dam on the described floating top edge buoyancy module.
Characteristics of the present invention are: floating top edge annular buoyancy module, the removable buoyancy module in middle part (or central removable buoyancy module) are designed to the piecemeal formula by single buoyancy module, and plate plate and all buoyancy modules adopt bolted connection, and all junctions are provided with special hermetically-sealed construction.The whole batch production of manufacturing work on floating top can reduce field activity greatly, improve workman's work situation; In service if certain buoyancy module leakage in floating top can be prefabricated in the factory earlier, is transported to on-the-spotly directly to change, thereby has avoided the safety that traditional floating top causes because of maintenance and the stopping production problem of oil tank, guarantees the oil tank long-term use.
