Description

Combine the gravity type bottom hull basis of anchoring pile and consolidated subsoil

Technical field

The utility model is related to a kind of gravity type bottom hull bases for combining anchoring pile and consolidated subsoil, are to traditional gravity type Bottom hull basis and the improvement on water conservancy project structure basis, the utility model belong to Underwater Engineering and ocean engineering field.

Background technology

The platform abbreviation settling type platform on gravity type bottom hull basis.It is the important kind of offshore oil mobile platform, base Plinth is gravity type bottom hull basis, it is mainly by two points of Group into first, the bottom hull of closed box composition, the closed box of bottom hull can It is divided into the cuddy of several separations, a part is ballast tank, and a part is variable buoyancy compartment, and another part is the deeper skirt that buries Plate, the platform on gravity type bottom hull basis is in place rear toward variable buoyancy compartment water filling, is inserted into soil and allowed by the gravity and skirtboard of bottom hull Platform stable, this similarly suitable all kinds of water conservancy project structure bases of form structure.Its great advantage is self installation and mobility, Variable buoyancy compartment water filling is excluded, bottom hull can refloat migration.Due to being gravity type foundation, i.e., before gravity is base fixed Carry, it requires that bottom hull has the comparable scale of construction, it is big that this just generates steel using amount, it is of high cost the problem of, require in addition that and be located sea bed energy Preferable frictional resistance is provided, because of frictional resistance=gravity x friction coefficient, the flexible subserate as the Bohai Sea, gravity type bottom hull basis is just not It is applicable in.If this type basis need not the excessive scale of construction, it is big to remove steel amount, it is of high cost and high to sea bed geologic requirements the shortcomings that, Retain its self installation and mobility advantage again, be undoubtedly significant to the construction of all kinds of water conservancy project structures.

Invention content

The purpose of this utility model is by the indignant thought on gravity type bottom hull basis, and removal conventional articulated gravity formula bottom hull basis is substantially Amount, it is big to remove steel amount, it is of high cost and high to sea bed geologic requirements the shortcomings that, and retain its self installation and mobility advantage, Used technical solution is；

1. bottom hull has the Marine Reinforced Concrete Structures block of notch for bottom；Top surface sets note concrete pipe valve and high pressure water jet pipe Valve, concret block bottom surface surrounding bury steel skirtboard, and quadrangle sets the bell-mouthed anchoring pile sleeve assembly of band of no less than six, according to need Concret block is wanted to install several steel columns.

2. the above-mentioned block of armored concrete according to need installs steel column, it is whole steel column for phytal zone, spreading side need to be used Case then makes horn mouth and fills diaphragm of rubber at the top of the steel column, and post jamb sets slip casting pipe valve, and bottom surface adds anchor plate, construction such as anchor Pile protection cartridge type sample.

The principle of this design be for area of base it is larger settling type basis, vertical support-as readily satisfy, main lance Shield is resistant slide, i.e., basis should provide enough horizontal supporting power, prevents from occurring to slide along the bottom of foundation or bottom surface subjacent bed coming Design, bibliography [1] has specific considerations, this is the paper Chinese that inventor herein delivers on International Academic Conference Version.Above-mentioned several measures is effectively ensure that resistant slide target creates condition.Be first for anchoring pile squeeze into create it is slotting Enter and righting condition, spray water after secondly bottom hull is in place by noting pipe of concrete pumping slurries, while by high pressure water jet pipe, then Change note concrete, bottom frictional resistance will be greatly improved in this way.The utility model can be widely applied to each water conservancy project structure basis, such as Wave energy electric generator basis, offshore wind power foundation, net cage basis, platform and off-shore structure basis etc..

Wherein：1. for armored concrete block, 101. steel skirtboards, 2. steel columns, 201. anchor plates, 3. slip casting pipe valves, 4. notes Concrete pipe valve, 5. spray water with high pressure pipe valve, 6. sluicing playpipes, 7. anchoring pile sleeve assemblies, 701. anchoring pile ferrule barrels, 702. sleeve horn mouth .703. horn mouth guide plates, 704. sleeve positioning plates, 705. mud guards, 706. slip casting pipe valves, 8. anchors Stake, 9. superstructure columns, 10. connection flexible pipes.

Specific embodiment

The armored concrete block 1 for giving field ramming processed good on land, it should be noted that being that a. uses cement for construction in sea, b. is using thin Aggregate strengthens density, and c. covers to reinforcement thicken, and presses figure installing steel skirtboard 101, steel column 2, anchoring pile sleeve assembly 7, and note is mixed Solidifying soil pipe valve 4, spray water with high pressure pipe valve 5, and steel skirtboard 101 is by being inserted into armored concrete block depth reliably to anchor.

When 1 scale of construction of armored concrete block is larger, should be lightered by partly latent to erecting bed waterborne, armored concrete block It is refuted on 1 then using passage method, armored concrete block 1, which is tied up, ties up aerated capsule, and partly latent is refuted sinking and removed, and ties up and ties up aerated capsule and put Gas sits bottom by armored concrete block 1, when armored concrete skirtboard injection mud, starts the pipe valve 5. that sprays water with high pressure and washes away, The electric submersible pump started simultaneously forms negative pressure, steel together with reinforced concrete block weight power through noting 4 pumping slurries of concrete pipe valve Reinforced concrete block 1 sinks down into designed elevation.With same system, note concrete pipe valve 4 changes note concrete special, is reinforced with reaching Ground purpose.

Anchoring pile 8 is squeezed into, the high-strength buckle slurry so far gravity of combination anchoring pile and consolidated subsoil of splashing is injected by slip casting pipe valve 706 Accomplish on formula bottom hull basis.Superstructure supporting leg is inserted into steel column 2 with crane after superstructure ships, passes through slip casting pipe valve 3, note Enter high-strength buckle slurry of splashing.

The utility model detaches on basis with superstructure, has actually followed offshore oil jacket construction thinking, because And there is simple and practical good operability, walk out a Tiao Xin roads for large volume gravity type bottom hull base application.
