Abstract
A composite cylinder type foundation with auxiliary piles added in the later period is composed of a cylindrical foundation body, a transition section, reinforcing ribs, auxiliary pile fixing ring sleeves and the auxiliary piles. The center of a cylindrical foundation body top cover is fixedly connected with the transition section. The transition section is connected with a fan tower cylinder through a flange. The reinforcing ribs are evenly distributed on the transition section and the cylindrical foundation body top cover annularly and radially. The reinforcing ribs, the transition section and the cylindrical foundation body top cover are prefabricated into a whole. The auxiliary pile ring sleeves are arranged at the bottom ends of the outer sides of the reinforcing ribs. After a cylindrical foundation structure is sunk, the auxiliary piles are driven into the cylindrical foundation structure, and the auxiliary piles are driven into a seabed through the auxiliary pile ring sleeves; and the auxiliary piles are fixedly connected with the auxiliary pile ring sleeves. The composite cylinder type foundation has the beneficial effects that due to the fact that auxiliary pile structures radially distributed on the edge of the composite cylinder type foundation have large pulling-resistant bearing capacity, the composite cylinder type foundation can resist the higher transverse load and the bending moment load; and by means of the cylinder type foundation, the standardized production and one-step type installation of the structure can be achieved, production and installation efficiency is improved greatly, and the production cost is lowered.
Description
Technical field
The present invention relates to offshore wind power foundation structure, 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.
Summary of the invention
It is an object of the invention to for above-mentioned existing problems, it is provided that a kind of later stage adds the compound bucket foundation of auxiliary pile, should
Compound bucket foundation can realize the compound cylinder-shaped foundation structure that standardized production is installed with single step, and ensures that cylindrical foundation is not
With the bearing capacity under foundation condition.
Technical scheme:
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 invention has the beneficial effects as follows:
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.
