Abstract
The utility model discloses a space truss type multi-bucket foundation of a seaborne wind-power generator unit, which mainly comprises a connecting cylinder, three suction buckets arranged triangularly or four suction buckets arranged quadrilaterally and supporting pillars with the same number of the suction buckets, wherein all suction buckets are connected with the connecting cylinder by corresponding supporting pillars; and support components of a truss structure are connected among the supporting pillars. A space truss system and multiple suction bucket-shaped foundations form an integral structure, and upsetting load born by the integral foundation is converted into vertical pushing load and vertical up-lifting load of single bucket-shaped foundations by the supporting pillars and the space truss; and the space truss type multi-bucket foundation fully utilizes the advantage that the bucket-shaped foundations can bear vertical load, has reasonably stressed structure, and can effectively solve the problems of high manufacturing cost and complicated construction of the seaborne wind-power generator unit.
Description
Technical field
The utility model relates to the form of structure on a kind of offshore structures basis, particularly at a kind of form of structure on offshore wind farm unit basis.
Background technology
China's coastal waters sea bed mostly is Deep Thick Soft Ground greatly, and construction offshore wind farm unit has proposed very big challenge to the selection on basis on this ground.The pattern of tradition offshore wind farm unit has: single pile basis and multi-column pier foundation.For the single pile basis, because itself level and resistance to compression bearing capacity are lower, in order to satisfy requirement for bearing capacity, pile foundation need be squeezed into to carrying condition bearing stratum preferably, thereby stake is long often longer, and cost is higher, to geology conditional request height, and need special large-scale piling ship to construct, the piling difficulty has further increased operating expenses.Also need set up interim operation platform and template, the work progress complexity during for the offshore concrete bearing platform construction of multi-column pier foundation.In addition, the offshore wind farm unit just gradually to big depth condition (15～40m) development, traditional base form is difficult to satisfy this requirement, thereby need seek that new opposing superstructure topples that weight bearing power is strong, easy construction, foundation structure form that cost is lower.
The utility model content
Technical problem to be solved in the utility model provides a kind of space truss multi-barrel base that reduces the offshore wind farm unit of cost.
Design of the present utility model is: in the weak soil of ocean, the suction type barrel base vertically press down and on to pull out load-carrying properties all better, and adopt the negative pressure construction also comparatively convenient at sea.The utility model utilize the support member of support column and space truss structure make the major part of superstructure topple load be converted into act on the suction type barrel base vertically press down and on pull out load, make them do as a whole basis as the wind-powered electricity generation unit.Basic pattern of the present utility model need not special piling ship, has reduced foundation cost.Total is stressed rationally, is suitable for resisting the huge load that topples of superstructure, is particularly useful on China's Deep Thick Soft Ground sea bed, the large-scale wind electricity unit under the big depth condition, and difficulty of construction is low.
The technical solution adopted in the utility model is as follows: the space truss multi-barrel base of this offshore wind farm unit mainly comprise connecting cylinder, three suction type buckets that are triangularly arranged or be four suction type buckets that quadrangle arranges, with the identical support column of described suction type barrelage amount, each suction type bucket is fixedly connected by corresponding support column and connecting cylinder, is connected with the supporting member of trussed construction between each support column.
Further, support column described in the utility model is a hollow structure, is perfused with filler in the cavity of this support column.
Further, the bung top of suction type bucket described in the utility model is provided with cavity, and the cavity of this bung is communicated with the sealing of the cavity of support column, is perfused with filler in the cavity of described bung.
Compared with prior art, the utility model has the advantages that: (1) has been avoided traditional single pile basis and multi-column pier foundation offshore construction complicated problems, and has been reduced construction costs because the suction type bucket utilizes negative pressure mode to sink and passes through.(2) the utility model efficiently solves offshore wind farm unit basis, the complicated difficult problem of construction by the supporting member of support column, trussed construction and many suction type buckets structure that forms a whole.(3) utilize the suction type bucket to bear the advantage of vertical load, supporting member by support column and trussed construction with superstructures such as wind motor act on major part on the connecting cylinder topple load be converted on the suction type bucket vertically press down and on pull out load, make structure stress reasonable.(4) filler such as concrete perfusion in the cavity of the bung top of suction type bucket and hollow support post, can increase the vertical pressure of the utility model space truss multi-barrel base, thereby can effectively reduce the uplift force of single suction type bucket, further improve the whole overturning or slip resistance analysis bearing capacity of space truss multi-barrel base.

The specific embodiment
Further set forth the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 3, the space truss multi-barrel base of the offshore wind farm unit in the present embodiment is provided with three suction type buckets 1, and these three suction type buckets 1 are plane triangle to be arranged, can make whole barrel base have stability preferably.Arrange if three suction type buckets 1 are equilateral triangle, can guarantee further that then whole barrel base has stable bearing capacity when different directions is toppled load, thereby have better stability.
As shown in figures 1 and 3, identical with the quantity of suction type bucket 1, three support columns 2 are arranged.The outer wall of connecting cylinder 4 is installed with a bracing frame 8.Each suction type bucket 1 is fixedly connected by the bracing frame 8 of a support column 2 with connecting cylinder 4; Be connected with the supporting member 3 of trussed construction between each support column 2, enough rigidity and stability arranged to guarantee whole barrel base.Connecting cylinder 4 is used to connect the tower tube of top wind-powered electricity generation unit.
As shown in Figure 1, the top of each support column 2 is exposed sea 6 and is poured in the support column 2 to avoid seawater.Support column 2 can be the steel pipe of hollow.
The utility model utilizes suction type bucket 1 to bear the advantage of vertical load, supporting member 3 by support column 2 and trussed construction with superstructures such as wind motor act on major part on the connecting cylinder 4 topple load be converted on the suction type bucket 1 vertically press down and on pull out load, make structure stress reasonable.Filler 5 such as concrete perfusion or sand in the support column 2 of the bung top of suction type bucket 1 and hollow, can increase the vertical pressure of the utility model space truss multi-barrel base, thereby can effectively reduce the uplift force of suction type bucket 1, further improve the overturning or slip resistance analysis bearing capacity of mass-type foundation.
As another kind of embodiment of the present utility model, the utility model also can be provided with four suction type buckets 1 as shown in Figure 2, and these four suction type buckets 1 are quadrangle and arrange.With in like manner aforementioned,, can further strengthen the stability of whole barrel base if four suction type buckets 1 are arranged to square.
