The utility model provides a tilting bucket foundation can make full use of tilting bucket foundation lateral wall and dead weight of the steel pterygoid lamina upper portion soil body and the frictional force improvement resistance to plucking bearing capacity of basis with the soil body when receiving the up -pull load. The utility model discloses can fix single or the showy structure in a plurality of seas, work as the utility model provides a when tilting bucket foundation upper portion and lower part crab -bolt all received the up -pull load, the running torque that tilting bucket foundation produced this moment can effectually be resisted in the dead weight of the steel pterygoid lamina and the basic upper portion soil body.
Description
Technical field
The utility model belongs to floating structure in ocean engineering to be fixed and anchors technical field, is specifically related to a kind of tilting barrel base mooring system.
Background technology
In recent decades, along with society is to the sharply increase of petroleum resources demand, the scarcity day by day of land energy resources, the emphasis of people to energy development starts to turn to ocean by land, and the exploitation of marine energy resource gets prosperous with every passing day.According to the prediction of the world energy sources committee, 10% will be increased than 2013 to the offshore wind farm installed capacity of the year two thousand twenty world.But, because the depth of water is on the impact of foundation construction cost and difficulty of construction, offshore wind farm single-pile foundation and gravity type foundation are applicable to the shallow sea that the depth of water is no more than 30m, after the degree of depth is more than 80m, select floatation type marine wind electric field more economical, and do not need complicated construction machinery.Therefore barrel base becomes the most preferred a kind of deep water foundation form of floating marine structure, and current barrel-shaped plinth has been applied to the sea bed deeply reaching 2000m.
Barrel base is the steel drum basis of a kind of bottom opening, top closure, it is a kind of novel offshore foundation form, in clay foundation or sand foundation, basis sinks by suction the mode injection sea bed passed through, after finishing using in basis, basis can be made to eject sea bed to basic internal water filling and utilize again.Barrel base has easy construction, saves cost, adapts to different water depth and the advantage such as reusable, is widely used in the engineerings such as marine wind electric field, offshore platform foundation and floating production unloading system.The uplift resistance that China in 2014 utilizes suction basis to provide first is just pulled to shipwreck the biggest in the world " TRANSSUMMER " wheel, this be in the world first by suction base application to marine Salvage.
Current barrel base mostly is vertical sea bed and sinks the single barrel base passed through, and when fixing for floating marine structure, mainly through increasing the size on basis to improve its anti-pulling capacity, also has the anti-pulling capacity adopting the mode of multi-barrel base to improve basis in addition.Although these two kinds of modes can increase the anti-pulling capacity on basis to a certain extent, for floating marine structure provides fixation, while increasing key dimension and quantity, also necessarily increase cost and the difficulty of construction on basis.
To sum up, in order to improve, ability is fixed to floating marine structure, reduce the cost of offshore anchoring system, accelerate the construction of deep-sea ocean platform and marine wind electric field, promote the exploitation of marine energy sources resource, need to propose a kind of novel offshore anchoring system that anti-pulling capacity can be provided higher.
Summary of the invention
In order to reduce the cost of offshore anchoring system, providing a kind of anti-pulling capacity higher and the offshore anchoring system of anchoring can be provided for multiple floating structure, the utility model proposes a kind of tilting barrel base mooring system.
For achieving the above object, the utility model discloses a kind of tilting barrel base mooring system, comprise floating marine structure, buoy, anchor chain, discharge ring, tilting barrel base, gutter, crab-bolt and steel wing plate, described tilting barrel base utilizes the heavy mode of passing through of suction to be embedded in sea bed; Steel wing plate and crab-bolt are symmetrically welded on the sidewall of tilting barrel base; In the middle of the top cover of tilting barrel base, welding one is for the discharge ring of basis lifting, and two gutters with switch are installed in discharge ring both sides; Anchor chain bottom and anchor bolts, top is installed buoy and is connected with floating marine structure.
In the utility model, the top cover of tilting barrel base is parallel with foundation bottom anchor ring, and the angular range of tilting barrel base and horizontal plane is 30 ° ~ 90 °.
In the utility model, crab-bolt is arranged symmetrically with along tilting barrel base top and bottom sidewall, crab-bolt has semicircular anchor hole, and steel wing plate is arranged along about tilting barrel base.
In the utility model, gutter is provided with drainage switch, drainage switch is only installed at tilting barrel base and is opened when extracting, and when tilting barrel base mooring system normally uses, drainage switch is in closed condition.
The beneficial effects of the utility model are:
(1) tilting barrel base effectively can utilize the ability providing opposing uplift load based on the soil pressure of the foundation side wall upper and lower soil body;
(2) steel wing plate adds the lifting surface area on basis, the rotating torque ability produced when improve basis opposing floating structure multiple by mooring, and then improves the anti-pulling capacity on basis;
(3) single mooring system can simultaneously for multiple floating structure provides anchoring, and multiple mooring system also can be used to provide anchoring for multiple floating marine structure simultaneously.

Detailed description of the invention
(1) first crab-bolt 5 is connected with anchor chain 2 and tilting barrel base 6 is fixed by discharge ring 3 when implementing tilting barrel base mooring system; Open gutter 4, suction pump is connected with gutter 4.
(2) on sea bed, tilting barrel base 6 is positioned, first utilize basic self gravitation injection sea bed, adjust the angle on basis.
(3) when no longer declining under the Gravitative Loads of tilting barrel base 6, loosen anchor chain 2, open suction pump, tilting barrel base 6 is carried out to suction is heavy to be passed through, close drainage switch time concordant with sea bed face to basic top cover, remove suction pump.
(4) on anchor chain 2 top, buoy 8 is installed, anchor chain 2 upper end is connected with required fixing floating marine structure 1.
