Description
Technical field
It the utility model is related to the design field of ocean engineering, more particularly to a kind of structure of jack up service platform shoe
Design.
Background technology
Jack-up unit is mainly used in offshore drilling, oilfield services, and life is supported and wind-powered electricity generation is installed etc..From top to bottom according to
It is secondary to be mainly made up of main hull structure, spud leg and shoe.Shoe is located at spud leg lower end, when platform sits bed die formula, shoe insertion
Seabed, give spud leg larger bearing area, the corresponding requirement for reducing platform to resistance of soil and plug-in depth of pile, main hull is then
Sea specified altitude assignment is risen to by spud leg, avoids long crested waves from impacting.
The appearance and size of shoe is generally dependent on platform weight and operating load, and the weight one of same type jack-up unit
As it is closely related with operating water depth.In general, operating water depth is deeper, and platform is heavier, and required shoe size is bigger；Instead
It, platform is then lighter, and required shoe size is with regard to smaller.Under normal circumstances, large scale shoe can be brought tired to pile pulling operation
Difficulty, the shoe of small size are not readily available larger pile foundation counter-force again.
Marine geo-hazard is complicated, and general platform operations region sea bed supporting course soil is broadly divided into batt, silty clay
And closely knit Extra-fine sand etc..In general, common jack-up unit can cause shoe driving depth mistake when compared with soft formation operation
Greatly.And platform pile shoe pitching pile driving depth crosses conference and significant damage is caused to platform, spud leg very likely occurs to puncture and cause
Platform topples；And jack-up unit, in harder stratum operation, because shoe driving depth is excessively shallow, shoe bottom contacts with seabed
Area is small, and bottom is easy to produce sliding because ocean current washes away and emptied, and shoe bottom local pressure can be caused excessive, makes knot
Structure failure damage.At the same time, batt is larger to shoe absorption affinity, and pile pulling difficulty also can accordingly increase.Therefore, also need to
Shoe is equipped with and more efficiently rushes stake system.So the change of geologic(al) factor is easy to have influence on the operating area of platform.
Therefore, it is necessary to design the shoe of a kind of reasonable size and form, can not be limited by coastal waters seabottom geology condition,
Larger pile foundation counter-force and the easy shoe of pile pulling can be readily available again simultaneously.
Utility model content
The utility model provides a kind of novel self-lifting type platform pile shoe structure, the shoe possess rational bottom area and
Structure type, it can adapt to the various Marine Geology conditions in coastal waters and facilitate platform pitching pile and pile pulling operation.
To realize object above, the utility model provides a kind of jack-up unit octagon shoe, including external shell
And internal structure, the top surface of shoe and bottom surface are respectively provided with certain slope；The internal structure forms shoe together with external shell,
Shoe is welded in spud leg lower end；Inside the insertion shoe of spud leg section of rack, shoe internal bulkheads dock composition six with spud leg rack
Side shape structure；Spud leg is connected on spud leg down tube with shoe by big riser；Shoe center is provided with shoe central tube, in shoe
The heart Guan Yuliu blocks bulkhead composition star structure of 60 degree of angles and extend to shoe periphery each other；Shoe bottom be pyramidal structure simultaneously
Provided with frustum；There is certain slope at the top of shoe；Shoe is provided with two access paths away from each other.
The bottom plate of access path 8 is apart from top plate vertical height between 860mm ~ 1500mm.
In a word, using a kind of jack-up unit octagon shoe of the utility model, to spud leg large carrying capacity, structure letter
It is single, it can adapt to the various Marine Geology conditions in coastal waters and facilitate platform pitching pile and pile pulling operation, job area wide so that platform is more
It is competitive.

Embodiment
A kind of new jack-up unit octagon shoe of the present utility model is described in detail with reference to accompanying drawing, should
It is clear that description herein is not used to limit the utility model only to explain the utility model.
As shown in Fig. 2, Fig. 3 and Fig. 5, the new jack-up unit octagon shoe mainly includes external shell and inside
Structure, the top surface of shoe and bottom surface are respectively provided with certain slope, and set one piece of frustum 7 in bottom center.
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 5, internal structure forms shoe 3 together with external shell, and shoe 3 is welded in stake
The lower end of leg 2, the section of rack of spud leg 2 are inserted inside shoe 3, and shoe internal bulkheads dock composition hexagonal structure with spud leg rack,
The stress of the area of shoe bottom 50% under dangerous situation can be ensured, spud leg 2 is connected to spud leg diagonal brace with shoe 3 by big riser 4
On pipe 5, to bear vertical reaction and corresponding horizontal load.The center of shoe 3 is provided with shoe central tube 6, shoe central tube 6 with
Six pieces the bulkhead composition star structure of 60 degree of angles and extend to shoe periphery each other, ensure shoe bulk strength and uniformly by
Power.Shoe bottom is pyramidal structure and is provided with frustum 7, and under hard paste soil property, shoe also can guarantee that one is incorporated into mud depth
Degree.The top of shoe 3 has certain slope so that during platform pile pulling operation, the soil of attachment departs from rapidly at the top of shoe, and shoe is set
Have two access paths 8 away from each other, at passage bottom plate apart from top plate vertical height between 860mm ~ 1500mm so that construction
And later stage maintenance has enough spaces.
Explanation embodiment of the present utility model is the foregoing is only, is not limited to form disclosed herein, should not
The exclusion to other embodiment is considered as, it is to those skilled in the art, all not depart from essence kind and original of the present utility model
Then scope, any modification, equivalent substitution and improvements made etc., all should be in the protection domain of the appended claims for the utility model
It is interior.
