Abstract
The utility model discloses a kind of anti-rotating skirt-type suction basis, it is included with the main bucket of suction of central shaft, skirt-type structure and four anti-rotating steel plates, the wherein main bucket of suction is top closure, a kind of steel base barrel shaped structure of bottom opening, its top sets osculum, skirt-type structure is be looped around suction main bucket periphery columnar structured, its top surface has been evenly arranged the permanent permeable circular hole of a circle, in main bucket periphery, equidistant vertical welds four anti-rotating steel plates, anti-rotating steel plate is located between the 0.45 1 0.7 of main bucket height, the height of anti-rotating steel plate determines according to the height, length takes the 1/2 of main bucket height.The utility model is compared with conventional barrel basis, increase the contact area on basis and ground, the horizontal and vertical bearing capacity on suction basis is improve, horizontal displacement and the rotation displacement of generation of the basis under level and vertical uniform load q is reduced, the bearing capacity on basis is effectively improved.
Description
Technical field
The utility model is related to field of ocean engineering, more particularly to suitable for offshore wind energy project foundation of sea floor base
Plinth.
Background technology
Suction basis is to be applied to ocean engineering in recent years, the foundation pattern with good its development.It has fortune
It is defeated with easy construction, shorten the duration, it is repeatable the advantages of utilize and be cheap, compensate for traditional jacket platform and gravity
The deficiency of the fixed shallow sea offshore engineering structure such as formula platform etc., has obtained relatively broad application in ocean engineering.
Traditional suction basis increases during being acted on by horizontal loading, vertical load, cyclic load etc. with the time
Length can produce larger horizontal displacement and corner, easily migrate, it is impossible to ensure the stability of foundation of sea floor infrastructure.
The content of the invention
For the deficiency that existing suction basis is present, the utility model provides a kind of anti-rotating skirt-type suction basis, should
Basis increases the contact area on basis and the soil body by increasing skirt and anti-rotating steel plate, reduces around cylinder to a certain extent
The washed out degree of seabed soil, effectively improves the horizontally and vertically bearing capacity of infrastructure, improves the steady of foundation of sea floor facility
It is qualitative.
To achieve the above object, construction of the present utility model is：A kind of anti-rotating skirt-type suction basis, it is characterised in that：
It includes the main bucket of suction with central shaft, skirt-type structure and four anti-rotating steel plates, and the wherein main bucket of suction is top closure, bottom
A kind of steel base barrel shaped structure of opening, its top sets osculum, and skirt-type structure is the cylinder for being looped around the main bucket periphery of suction
Shape structure, its top surface has been evenly arranged the permanent permeable circular hole of a circle.
A kind of anti-rotating skirt-type suction basis, it is characterised in that：In main bucket periphery, equidistant vertical welds four anti-rotating steel
Plate, anti-rotating steel plate is located between the 0.45 1 0.7 of main bucket height, and the height of anti-rotating steel plate determines according to the height, length
Take the 1/2 of main bucket height.
Specific implementation method when the utility model is used is：Skirt-type suction is basic under effective weight effect first,
Sink in seawater, sink to seabed, staving cuts sea bed, staving top osculum is always on during this, skirt-type suction basis
Deadweight is heavy to pass through end；Then staving top osculum connection drainage system, drains the water body in staving, forms negative in staving
Continue to sink under suction function in pressure, suction basis；Sunk in the range of most rear skirt and passed through, top surface is provided with permanent drains hole, suction base
Plinth closes osculum when sinking to precalculated position, remove drainage system, and whole construction terminates.
Compared with prior art, advantage of the present utility model is：The setting of shirt rim and anti-rotating steel plate is substantially increased
The ability of basis resistance seabed soil erosion, it is ensured that bearing capacity is not reduced because by seabed soil erosion, so as to extend basis
Life-span.Shirt rim and anti-rotating steel plate increased the contact area of basis and the soil body, improve the horizontally and vertically carrying on basis
Power, improves the stability of foundation of sea floor facility.
Brief description of the drawings
Fig. 1 is a kind of structural representation on anti-rotating skirt-type suction basis of the utility model.
Fig. 2 is a kind of structure schematic top plan view on anti-rotating skirt-type suction basis of the utility model.
Marginal data：The main bucket of 1 one suction；2 one skirt-type structures；3 one anti-rotating steel plates；4 one osculums；5 one permeable circular holes.
Specific embodiment
The utility model provide a kind of anti-rotating skirt-type suction basis, for make the utility model realize technical scheme,
Reached purpose and effect characteristic are more explicit, and its specific embodiment is further elaborated below in conjunction with the accompanying drawings.
Such as Fig. 1, shown in Fig. 2, a kind of anti-rotating skirt-type suction is basic, and it is included with the main bucket 1 of suction, the skirt-type knot of central shaft
Structure 2 and four anti-rotating steel plates 3, the wherein main bucket 1 of suction are top closures, a kind of steel base barrel shaped structure of bottom opening,
Its top sets osculum 4, and skirt-type structure 2 is be looped around the main periphery of bucket 1 of suction columnar structured, and its top surface has been evenly arranged one
The permanent permeable circular hole 5 of circle.
A kind of above-mentioned anti-rotating skirt-type suction basis, it is characterised in that：Four are welded in the peripheral equidistant vertical of main bucket 1 to resist
Rotate steel plate 3, anti-rotating steel plate 3 is located between the 0.45 1 0.7 of the height of main bucket 1, the height of anti-rotating steel plate 3 according to this highly
It is determined that, length takes the 1/2 of the height of main bucket 1.
Specific implementation method when a kind of anti-rotating skirt-type suction basis of the utility model uses is：Skirt-type suction base first
Plinth sinks under effective weight effect in seawater, sinks to seabed, staving incision sea bed, the main top of bucket 1 row of suction during this
Water hole 4 is always on, and the deadweight of skirt-type suction basis is heavy to pass through end；Then staving top osculum 4 connection drainage system, drains bucket
Internal water body, forms negative pressure in staving, and suction basis continues to sink under suction function；Finally sunk in the range of " skirt " and passed through,
Top surface is provided with permanent permeable circular hole 5, and osculum is closed on suction basis when sinking to precalculated position, remove drainage system, entirely
Construction terminates.
