Diversified due to different sea situations.The fixed basis of weak soil sea bed offshore wind farm unit common are: pile foundation (includes single
Stake, high-rise pile cap, many pile leaders frame), gravity type, negative pressure bucket.Gravity type foundation needs marine levelling；Single-pile foundation needs to be equipped with
Heavy construction equipment；Multi-pile structure sea operation is on the high side, and construction efficiency is low.
Accordingly, it is desirable to provide a kind of many barrels of negative pressure bucket jacket-type offshore wind turbine foundations are solving the above problems.
Utility model content
In order to solve this problem, the utility model discloses a kind of many barrels of negative pressure bucket jacket-type offshore wind turbine foundations, it
Efficiently solve when weak soil sea bed builds big megawatt of blower foundation, need sea bed levelling or be equipped with asking of large-scale pile driving equipment
Topic, decreases offshore construction operation, improves construction efficiency, reduce construction cost, in addition compared with single barrel of negative pressure barrel base,
Go for the deeper marine site of the depth of water.A kind of many barrels of negative pressure bucket jacket-type offshore wind turbine foundations, it includes: catheterostat steel knot
Structure (11) and two or more negative pressure bucket (6) are it is characterised in that described catheterostat steel construction (11) top is provided with work platformses
(10), work platformses (10) are provided with changeover portion (2) above, and changeover portion (2) is provided with tower (1) above；More than sea level (9)
Catheterostat steel construction (11) is provided with halfpace (3) above, and halfpace (3) is connected with cat ladder (4)；Run through catheterostat steel construction
(11) top to bottom is provided with an extra large cable pipe (8), is provided with two or more negative pressure bucket in catheterostat steel construction (11) bottom
(6), and it is respectively equipped with air extractor (7) above each negative pressure bucket (6), air extractor (7) is in sea bed face (5) with upper bit.
The beneficial effects of the utility model are:
This utility model portable construction, install simple, it is levelling both need not to have carried out sea bed, sets without being equipped with Large Construction
Standby.
In conjunction with advantages and features of the present utility model described further below.
Brief description
Fig. 1 is organizational structure schematic diagram of the present utility model.
Specific embodiment
In the following description, give a large amount of concrete details to provide, this utility model more thoroughly to be managed
Solution.It will be apparent, however, to one skilled in the art that this utility model can be one or more of these thin
Save and be carried out.In other examples, in order to avoid obscuring with this utility model, for more well known in the art
Technical characteristic is not described.
In order to thoroughly understand this utility model, detailed structure will be proposed in following description.Obviously, this utility model
Execution be not limited to the specific details that those skilled in the art is familiar with.Preferred embodiment of the present utility model is retouched in detail
State as follows, but in addition to these describe in detail, this utility model can also have other embodiment.
Hereinafter embodiment of the present utility model is described in detail.
With reference to Fig. 1, a kind of many barrels of negative pressure bucket jacket-type offshore wind turbine foundations, it includes: catheterostat steel construction (11) and
, it is characterised in that described catheterostat steel construction (11) top is provided with work platformses (10), work is flat for two or more negative pressure bucket (6)
Platform (10) is provided with changeover portion (2) above, and changeover portion (2) is provided with tower (1) above；Catheterostat steel knot more than sea level (9)
Structure (11) is provided with halfpace (3) above, and halfpace (3) is connected with cat ladder (4)；Run through the top of catheterostat steel construction (11)
It is provided with an extra large cable pipe (8) to bottom, is provided with two or more negative pressure bucket (6) in catheterostat steel construction (11) bottom, and each is negative
Pressure bucket (6) is respectively equipped with air extractor (7) above, and air extractor (7) is in sea bed face (5) with upper bit.
The embodiment of the present embodiment is: the present embodiment top is catheterostat steel construction (11), and bottom is born for two or more
Pressure bucket (6), each negative pressure bucket (6) is respectively equipped with air extractor (7) above, and basis adjusts the negative of each negative pressure bucket (6) when sinking
Pressure size is so that basis uniformly sinks；The present embodiment working procedure is roughly the same with catheterostat basis: steel structure base is pre- on the bank
System → basic transport → foundation immersion；The present embodiment compared with gravity type foundation, before this foundation construction sea bed need not carry out excavating,
Leveling, this basis can carry out sinking operation using crane ship, during sinking, to basis by way of interval, point sequence
Each negative pressure bucket carries out gas pump drainage, and under the collective effect of negative pressure, basis deadweight and loaded weight, basis uniformly sinks, until base
Plinth top reaches designed elevation.
The having the beneficial effect that of the present embodiment
The wave load that the present embodiment is born with Conventional gravity formula basis structure compared is less, with single barrel of negative pressure barrel base phase
Stronger than resistance to capsizing, have the advantages that marine operation is few, efficiency of construction is high, low cost.
