Description
Technical field
This utility model relates to offshore wind power foundation structure, and a kind of later stage adds the compound bucket foundation of auxiliary pile.
Background technology
In recent years, offshore wind farm quickly grows as a kind of green clean reproducible energy, and its market is almost with every year
The speed of more than 40% increases swift and violent.Offshore wind farm has that wind field quality is good, turbulivity is little, be not take up ploughing, utilize in year little
The significant advantages such as Shi Gao.But maritime environment is complicated, stormy waves stream is complicated to the coupling of basis and pylon structure, and sea water is to basis
Wash away obvious with corrosion function.Simultaneously as maritime environment is complicated, the difficulty of construction of base structure is relatively big, relatively costly, and
Later stage monitoring and maintenance is costly.Therefore, how to improve the bearing capacity of base structure, and to reduce cost be offshore wind farm
The key issue of technology development.
In numerous offshore wind power foundation structures, compound cylindrical foundation is shown as a kind of emerging base structure
It is at the superiority of wind power foundation technical field.Compound tubular base structure has good bearing capacity and transportation by driving ability.
But, due to the difference of the geological conditions of different wind fields, the geological conditions difference of the most identical wind field different regions so that tubular
The size on basis differs greatly with the design of structure.This significantly limit the mass of cylindrical foundation structure, standardized life
Producing, its design is of a relatively high with the cost manufactured.Simultaneously as the design of cylindrical foundation structure is decided by the geology of addressing substantially
Condition, relative transportation by driving condition considers less with sinking condition, thus adds being constructed into of cylindrical foundation to a certain extent
This.Most importantly, due to compound cylindrical foundation is that single structure carries, once bearing capacity deficiency, entirety can be caused
Structural damage, risk is bigger.Proposing a kind of later stage for this application and add the compound bucket foundation of auxiliary pile, this basis is by cylinder
Jointly carry with auxiliary pile, reduce the risk that entirety is destroyed, improve bearing capacity so that the design of cylindrical foundation structure is cleverer
Live, thus the standardized production that can realize cylindrical foundation is installed with single step, reduces cost, improves efficiency.
Utility model content
The purpose of this utility model is for above-mentioned existing problems, it is provided that a kind of later stage adds the compound cartridge type base of auxiliary pile
Plinth, this compound bucket foundation can realize the compound cylinder-shaped foundation structure that standardized production is installed with single step, and ensure tubular base
Plinth bearing capacity under the conditions of different grounds.
The technical solution of the utility model:
A kind of later stage adds the compound bucket foundation of auxiliary pile, by cylindrical foundation, changeover portion, ribs, auxiliary pile retainer ring
Set and auxiliary pile are constituted, and cylindrical foundation top cover is reinforced concrete structure, and sidewall is steel construction;Cylindrical foundation top cap central and mistake
The section of crossing is fixing to be connected;Changeover portion is steel construction, and diameter and blower fan tower barrel lower end diameter quite and pass through flange and blower fan tower barrel phase
Even;Changeover portion and cylindrical foundation top cover arrange 4-8 the radial equally distributed ribs of hoop;Ribs is steel construction, with
Changeover portion and cylindrical foundation top cover are made as unified entirety in advance;Ribs outer lower end arranges 4-8 auxiliary pile ring set;Auxiliary anchor ear
Set is steel construction, is welded and fixed with ribs;Squeezing into auxiliary pile after cylindrical foundation structure is sunk, auxiliary pile number is with auxiliary
Help anchor ear set number identical;Auxiliary pile squeezes into sea bed by auxiliary pile ring set respectively;Auxiliary pile is steel construction, with auxiliary pile ring set
Fixing connection.
The beneficial effects of the utility model are:
This compound bucket foundation has bigger resistance to plucking bearing capacity because of the auxiliary pile structure of the radial distribution in its edge, makes
Obtain this base structure and can resist higher, more complicated lateral load and moment load;Simultaneously because structure bending resistance, shear resistance
Raising so that the design of tubular construction can be wholly constrained to the factor of geological conditions, and more consideration structure is made
Cost, the optimum transportation by driving degree of depth and optimum sinking condition;This cylindrical foundation can realize the standardized production of structure and install with single step,
Greatly improve the efficiency producing with installing, reduce production cost.
