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 comes the resistance to plucking bearing capacity on increase bucket basis and the area of contact increase basis of ground at the annular groove that original suction bucket basis bucket wall outside set up three lower part and have a grade.

Description

A kind of novel suction anchor strengthening withdrawal resistance
Art
This utility model belongs to ocean engineering field, is widely used in various offshore structure facility, such as ship mooring, keg float location, storage facility, beacon, catheterostat and platform etc. Along with the basis extensive use 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 the aggravation of world energy sources shortage and environmental problem, marine wind energy is the regenerative resource of a kind of great Utilization prospects, as marine wind energy resource-rich country, wind power generation will be the important ring in following China energy strategy, and the energy in order to solve facing mankind lacks problem. The basis of wind-power electricity generation is the important component part of marine wind field, it is necessary to bear the load of superstructure.
Suction basis, as a kind of marine facility basis, is widely used in ocean engineering. The common ground of suction base 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. It carries out heavy passing through by the negative pressure formed after conducting oneself with dignity and drawing water, and arrives specific bit and postpones the load bearing superstructure. But, when bearing bigger moment of flexure or bigger uplift force when suction bucket basis, have the possibility of destruction. For improving the bearing capacity on basis, a kind of novel foundation bearing bigger moment of flexure and uplift force need to be researched and developed.
Summary of the invention
In order to overcome the deficiency of existing suction bucket, this utility model provides a kind of novel suction bucket basis, and this basis can increase the anti-pulling capacity on basis.
This utility model solve its technical problem be the technical scheme is that by outside the bucket wall of original barrel-shaped suction basis from 0.1 times, bottom bucket eminence set up three spacing be the bottom that 0.1 times of bucket is high have the annular groove of certain slope to increase barrel-shaped suction basis and ground contact area thus increasing the anti-pulling capacity on barrel-shaped suction basis.
Effective benefit of the present utility model is to increase the anti-pulling capacity of barrel base, simple in construction.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is this utility model schematic diagram.
Fig. 2 is this utility model front view.
Fig. 3 is this utility model top view.
Detailed description of the invention
In the construction stage, in Fig. 1, first barrel base sinks to passing through at Gravitative Loads, open bucket top suction eye (3) when heavy passing through cannot be allowed to continue to after sinking certain depth under deadweight state to draw water, thus in the closing space that bucket and ground surround and externally-generated negative pressure, thus continue heavy passing through. When upper load transmits pulling force upwards, staving (1) and three annular grooves (2) and the foundation soil contacted or sand produce frictional force and increase resistance, it is provided that withdrawal resistance.

Claims (2)

1. barrel-shaped suction basis, is characterized in that: be the annular groove that size that 0.1 times of bucket is high is identical setting up three spacing from 0.1 times, bottom bucket eminence.
2. barrel-shaped suction according to claim 1 basis, is characterized in that: bucket wall outermost becomes 30 degree of angles with annular groove.
