It includes steel -pipe pile, annular slab, rib and the wing, and the steel -pipe pile welding has the annular slab, and the annular slab upper surface passes through the rib to be connected with the steel -pipe pile, the rib be triangle -shaped, the welding of annular slab below has a plurality of wings, crisscross setting of rib and the wing. The utility model discloses a set up the reinforced plate on fin upper portion, make every effort to reduce cost when increasing pile foundation rigidity to promote marine wind power's commercialized process.
Description
Technical field
This utility model is related to technical field of power generation and in particular to one kind is new adds wing stake.
Background technology
With the increase of global warming and energy scarcity pressure, Oversea wind power generation is increasingly becoming new energy field
Development priority.Cost of electricity-generating is the bottleneck of offshore wind farm development, and the principal element affecting offshore wind farm cost is basis knot
Constitute this (including manufacturing, install and safeguarding).At present, in the gross investment of marine wind electric field, base structure accounts for 15~25%, and land
Upper wind energy turbine set is only 5~10%.Therefore, the offshore wind power foundation structure developing low cost is reduce offshore wind farm cost one
Main path.
At present, offshore wind turbine generator foundation structure has gravity type, single pile structure, tripod structure, jacket structure, barrel-shaped
Basis and floating structure etc..Deposits in Eastern Coastal China coastal waters wind energy resources enriches, and has the supremacy clause of exploitation offshore wind farm.But I
State's deep water offshore is shallower, and submarine surface is mud, silty clay and silty sand ground, and bearing capacity is little;Basic sediment based on fine sand,
Bearing capacity is relatively large, can make supporting course.Therefore gravity type foundation and barrel base should not be adopted, piling strtucture can be adopted.King
Scape full academician point out, China's development offshore wind farm will be with piling strtucture for main base form.
Compared to other engineerings, in order to ensure the normal of blower fan and safe handling, for pile crown horizontal displacement and corner
Require very strict, according to German engineering experience, the accumulation corner permissible value at pile foundation mud face is 0.5 °.In order to meet in engineering
This strict restriction is it has to be realized by increasing the buried depth of single pile, and this also directly results in being greatly improved of infrastructure investment,
Propose a kind of new single pile pattern-plus wing stake for this in the world, that is, specific in the pile body of conventional large diameter single pile foundation
At position, (typically at shallower position below foundation surface) installs fin additional, in the hope of improving pile foundation in the case of cost increase is less
Rigidity, effectively reduces pile deflection.But fin breakage phenomenon occurs in test, thus pile foundation is led to produce the danger of over-large displacement
Evil.Kong Linggang etc. proposes a kind of fin stake, if actually arranging arterial highway fin in pile body total length according to a determining deviation, this
Although kind of a pile-type can be greatly improved STIFFNESS BOTH THE BASE, there is stake end nearby fin is inefficient, pile body weight is excessive etc. and ask
Topic, can propose rigors to the offshore set-up ability such as pile hammer in Practical Project.So urgently occurring a kind of new in engineering
Pile-type, the strict demand with regard to displacement in design specification can be met, and cost is relatively fewer, sea is applied at present with China
Work ability matches;This utility model designs a kind of new pile-type, strengthens hardened structure by arranging in flap upper, is increasing pile foundation
Reduces cost is made every effort to, thus promoting the commercialization process of offshore wind farm while rigidity.
Utility model content
For solving the above problems, this utility model provides a kind of new plus wing stake, is strengthened by arranging in flap upper
Plate, makes every effort to reduces cost, thus promoting the commercialization process of offshore wind farm while increasing STIFFNESS BOTH THE BASE.
For achieving the above object, the technical scheme that this utility model is taken is: a kind of new plus wing stake, including steel-pipe pile,
Annular slab, rib and the wing, steel-pipe pile is welded with annular slab, and annular slab upper surface is connected with steel-pipe pile by rib, and described rib is three
Angular, it is welded with multiple wings below annular slab, described rib and the wing are crisscross arranged.
Preferably, the described wing is three wings or four wings.
Preferably, the described wing is rectangle or right-angled trapezium.
Preferably, described wing array annular in shape is arranged on below annular slab.
This utility model has the advantages that by arranging enhancing plate in flap upper, is increasing STIFFNESS BOTH THE BASE
Make every effort to reduces cost, thus promoting the commercialization process of offshore wind farm simultaneously.

Specific embodiment
In order that the purpose of this utility model and advantage become more apparent, with reference to embodiments this utility model is entered
Row further describes.It should be appreciated that specific embodiment described herein is only in order to explain this utility model, and without
In restriction this utility model.
As Figure 1-4, this utility model embodiment provides a kind of new plus wing stake, including steel-pipe pile 1, annular slab 2,
Rib 3 and the wing 4, steel-pipe pile 1 is welded with annular slab 2, and annular slab 2 upper surface is connected with steel-pipe pile 1 by rib 3, and described rib 3 is three
Angular, it is welded with multiple wings 4 below annular slab 2, described rib 3 and the wing 4 are crisscross arranged.
It should be noted that the described wing 4 is three wings or four wings.The described wing 4 is rectangle or right-angled trapezium.
Additionally, the described wing 4 array annular in shape is arranged on below annular slab 2.
This specific embodiment adds the fin frangibility problem of wing stake presence for current offshore wind turbine, has invented a kind of new
Type adds wing stake, by arranging annular slab with ribbing in flap upper, while increasing STIFFNESS BOTH THE BASE and intensity, reduces its one-tenth
This, alleviate the weight of pile body, and fin service efficiency is high, and the wing pilework that adds of this specific embodiment designs more adduction
Reason, service life is longer, improves its service efficiency, practical.
The above is only preferred implementation of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
