Abstract

The utility model provides a novel suction anchor foundation. It includes that a bottom is uncovered, top confined staving, and the staving top is equipped with the wash port, in order to overcome the not enough of present suction bucket, thereby evenly sets up antitorque and the resistance to plucking bearing capacity that the one side that there is a grade 12 lower parts comes the area of contact increase basis of increase bucket basis and ground for the triangle -shaped recess on bent limit in original suction bucket basis bucket wall outside.

Description

A kind of novel suction anchor strengthening twisting resistance and uplift resistance
Art
The utility model belongs to ocean engineering field, is widely used in various offshore structure facility, as ship mooring, keg float location, storage facility, beacon, jacket and platform etc.Along with the extensive use of basis in ocean engineering field of suction anchor formula, it will become the base form of equal importance with the traditional infrastructure form such as pile foundation.
Background technology
At present, with world energy sources shortage and the aggravation of environmental problem, marine wind energy is a kind of regenerative resource having Utilization prospects, as marine wind energy resource-rich country, wind power generation will be the important ring in following China energy strategy, lack problem in order to the energy solving facing mankind.The basis of wind-power electricity generation is the important component part of marine wind field, needs the load bearing superstructure.
Suction basis, as a kind of marine facility basis, is widely used in ocean engineering.The common ground of suction foundation structure is similar to one inverted " bucket ", i.e. the drum structure of bottom-open, top seal, and bucket top is provided with suction eye.Its negative pressure by deadweight and formation after drawing water carries out heavy passing through, and arrives the load of assigned address consequence by superstructure.But, the possibility of destruction is had when larger moment of flexure or larger uplift force are born in suction bucket basis.For improving the bearing capacity on basis, a kind of novel foundation bearing larger moment of flexure and uplift force need be researched and developed.
Summary of the invention
In order to overcome the deficiency of existing suction bucket, the utility model provides a kind of novel suction bucket basis, and this basis can increase the antitorque and anti-pulling capacity on basis.
The utility model solves the technical scheme that its technical problem adopts: be that the triangular groove on bent limit increases the contact area of barrel base and ground thus increases basic antitorque and anti-pulling capacity by what evenly arrange outside the bucket wall of original suction bucket basis that certain slope is arranged at 12 bottoms.
Effective benefit of the present utility model is that increase the antitorque of barrel base and anti-pulling capacity, structure is simple.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the utility model top view.
Detailed description of the invention
In the construction stage, as in Fig. 1, first barrel base sinks to passing through at Gravitative Loads, draws water when making it to open bucket top suction eye (3) when continuing heavy passing through after sinking certain depth under deadweight state, thus produce negative pressure at the enclosure space that bucket and ground surround with outside, thus continue heavy passing through.When Upper Structure torsion load, staving (1) and the triangular groove (2) for bent limit extrude mutually with the foundation soil contacted with it or sand facies, provide opposing moment of torsion; When upper load transmits pulling force upwards, staving (1) and the triangular groove (2) for bent limit produce frictional force and increase resistance with the foundation soil contacted with it or sand, provide uplift resistance.

Claims (4)

1. a barrel-shaped suction basis, is characterized in that: install the triangular groove that 12 are bent limit to bucket bottom end 0.3 times of bucket is high.
2. barrel-shaped suction basis according to claim 1, is characterized in that: 12 equal-sized is that the triangular groove on bent limit is evenly arranged on staving one circle.
3. barrel-shaped suction basis according to claim 1, is characterized in that: for the triangular groove opening part on bent limit is except handing over distance from point to curved surface to be 0.5 times of bucket radius in the other both sides on bent limit.
4. barrel-shaped suction basis according to claim 1, is characterized in that: other two edge lengths that the triangular groove opening part for bent limit removes bent limit are equal.
