Description
Technical field
This utility model relates to a kind of offshore platform foundation, a kind of barrel base with fan-shaped cavity.
Background technology
Barrel base is applied to the North Sea platform of Norway the earliest the nineties, as a kind of novel ocean engineering basis,
Have speed of application fast, cheap, can the advantage such as repetitive cycling utilization, the most gradually instead of pile foundation, mainly apply
In offshore wind power foundation, the Geotechnical Engineering field, ocean such as ocean platform builds, floating marine structure is fixing.Its operation principle is:
First by deadweight and the weight of superstructure, insert seabed certain depth, formed after effectively sealing, then by pumped bucket
Air and water form negative pressure, utilize the projected depth that the pressure differential inside and outside bucket drives in basis in subsea strata.When platform needs
Time mobile, rechargeable gas is extracted basis from stratum.
Conventional barrel basis is the most inadequate in terms of opposing horizontal loading and drawing weight bearing power, is especially in multiple when it
In miscellaneous marine environment, barrel base is more easy to sidesway and rotation, has had a strong impact on the stable use of barrel base.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides a kind of barrel base with fan-shaped cavity,
The Its ultimate bearing capacity on this basis, vertical bearing capacity and breakout capacity are effectively promoted, and shearing resistance and bending rigidity obtain bright
Aobvious raising, extends the service life on basis.
To achieve these goals, the technical solution adopted in the utility model is: a kind of barrel-shaped base with fan-shaped cavity
Plinth, including staving, has inlet opening in the middle part of staving；Described staving upper periphery is evenly equipped with multiple fan-shaped cavity；Described fan-shaped chamber
The outline of body is sector, and outer end is in the arc-shaped.
This utility model is further, tapers off to a point bottom described staving.
This utility model is further, and described fan-shaped cavity bottom tapers off to a point.
This utility model is further, has sluicing notch in the middle part of described fan-shaped cavity.
This utility model is further, and described fan-shaped cavity is evenly equipped with four, is connected by rod member two-by-two between fan-shaped cavity
Get up.
This utility model is further, described staving top suspension ring are distributed.
This utility model is further, and the top of described fan-shaped cavity is fixed with suspension ring near end.
Owing to using technique scheme, this utility model has the advantage that the setting of (1) fan-shaped cavity makes basis
Shearing resistance and bending rigidity are improved significantly.(2) structure simple structure, form is brief, and globality is strong, centered by staving, all
Being furnished with fan-shaped cavity, connect further through rod member between cavity, globality and the rigidity on basis are strengthened.(3) staving and fan
The end of shape cavity is all made and is prone to the heavy tip passed through, for basis preliminary injection and heavy through journey be smoothed out there is weight
Want meaning.(4) compared with conventional barrel basis, there is higher level, vertical bearing capacity and anti-pulling capacity.(5) suspension ring
It is symmetrical arranged, good assosting effect is played for basis control of perpendicularity and stability in hoisting process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A-A profile in Fig. 1；
In figure: 1, staving, 2, inlet opening, 3, fan-shaped cavity, 4, sluicing notch, 5, rod member, 6, suspension ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, this utility model one is with the barrel base of fan-shaped cavity, including staving 1, in the middle part of staving 1
Have inlet opening 2, it is simple to basis is heavy pass through during draw water formation negative pressure and when needing mobile basis water filling basis is extracted, permissible
Open or close as required.It is evenly equipped with multiple fan-shaped cavity 3 in staving 1 upper periphery；The outline of fan-shaped cavity 3 is fan
Shape, outer end is in the arc-shaped, advantageously reduces sea water directly washing away basis.
On the basis of said structure, taper off to a point bottom staving 1, it is simple to basis is initially passed through such as mud and smooth sinking thereof.At fan
Tapering off to a point bottom shape cavity 3, the most advanced and sophisticated shape being similar to staving 1 end is made in its bottom, it is simple to coordinate heavy passing through with basis.At fan
Sluicing notch 4 is had in the middle part of shape cavity 3.Beneficially basis reduces resistance during heavy passing through, it is achieved sinks smoothly and passes through.
The quantity of fan-shaped cavity 3 can be adjusted according to practical situation, and scheme given here is that fan-shaped cavity 3 is uniform
There are four, coupled together by rod member 5 between fan-shaped cavity 3 two-by-two.Arrange and make the globality on basis be strengthened, the entirety on basis
Rigidity is improved.
Suspension ring 6 are distributed on staving 1 top；The end at the top of fan-shaped cavity 3 is also fixed with suspension ring 6,4 altogether,
The top of fan-shaped cavity 3 is fixed with suspension ring 6 near end.The arranging of suspension ring 6 can facilitate the lifting on basis and basis heavy through
Regulation in journey, it is possible to ensure heavy the stablizing through journey in basis.
This utility model is specifically heavy through journey: first passes through lifting and is placed into by a kind of barrel base with fan-shaped cavity
Position set in advance, can make full use of the symmetrical lifting rope interted in suspension ring 6 and carry out stability and perpendicularity in placement process
Regulation.Opening inlet opening 2, under the effect of deadweight, basis sinks to seabed certain depth, then utilizes suction pump to draw water formation
Negative pressure is by basis gradually injection.Heavy through journey, fan-shaped cavity 3 gradually starts such as mud, and sinking the water during passing through can be by sluicing
Notch 4 is discharged.Then staving 1 and fan-shaped cavity 3 start to work in coordination with sinking, note adjusting the vertical of basis entirety during this
Degree.Treat that basis injection to projected depth can complete heavy passing through.
Certainly, above-described embodiment is only preferred version of the present utility model, is specifically not limited thereto, and on this basis may be used
Make according to actual needs having and adjust targetedly, thus obtain different embodiments.Due to mode in the cards relatively
Many, illustrate the most one by one.
