Description
Technical field
This utility model relates to a kind of offshore wind farm embedding rock single-pile foundation.
Background technology
Due to increasing the weight of of increasingly serious energy crisis and problem of environmental pollution, the utilization of regenerative resource is increasingly becoming people
The emphasis of research and development.The most land wind-powered electricity generation has had large-scale exploitation, but it has many shortcomings and restrictive condition,
Therefore Oversea wind power generation initially enters people's sight line with its unique advantage.The advantage of Oversea wind power generation has: wind energy on the sea provides
During storage capacity Datong District, source the most more stable, sea surface roughness is little, sea turn turbulence intensity is little, wind trimming is little, development efficiency is higher, no
There is the problem of environmental pollution such as noise jamming, landscape destruction, be especially suitable for developing on a large scale.
The structural shape of offshore wind plant wind turbine foundation can be divided into gravity type foundation, single-pile foundation, many column foundations, suction type
Basis etc..The structure model selection of blower foundation, need to from base structure feature, natural geological conditions, offshore construction technology and experience with
And economy aspect is analyzed comparing.
Single-pile foundation refers generally to single steel pipe pile foundation, and it is structurally characterized in that convenient and quick construction, good economy performance；Single pile base
Plinth is made up of a steel-pipe pile, and its length of embedment is determined by the depth of water and geological conditions.Single-pile foundation is because of low cost, easy construction
And be applied widely abroad, use the ratio of single-pile foundation to reach more than 70% in Europe.Single-pile foundation be primarily subjected to wind,
The horizontal loads such as wave, its horizontal bearing performance is its key whether being suitable for.Owing to integral rigidity is relatively small, pile body position
Migration is toward relatively big, and the structural dynamic response under wave, wind action is relatively big, easily produces fatigue damage and even lost efficacy.With
The exploitation of offshore wind farm scale, Wind turbine single-machine capacity is increasing, and 5MW and above unit have been researched and developed successfully and thrown
Enter to use, use traditional single pile pattern, the diameter of stake and wall thickness to dramatically increase, both added cost, too increased and execute
Work difficulty.Simultaneously for coastal waters, part province sea bed shallow overburdens such as Fujian, in order to meet foundation bearing capacity, pile foundation often needs
Wanting embedding rock, for large-diameter pile, current embedding rock construction equipment lacks, and is difficulty with the embedding rock of major diameter tunneling boring.
Utility model content
In view of this, the purpose of this utility model is to provide the offshore wind farm embedding rock single-pile foundation of a kind of novel structure.
This utility model uses below scheme to realize: a kind of offshore wind farm embedding rock single-pile foundation, including be positioned at center and under
End inserts upper end in sea bed and is positioned at the steel pipe single pile on sea level, and described steel pipe single pile upper end is provided with blower fan tower barrel, steel pipe
Single pile inner peripheral portion or peripheral part are arranged at intervals with multiple steel pipe bored concrete pile being fixed on steel pipe single pile, described steel pipe bored concrete pile lower end
Insert upper end in sea bed and be positioned on sea level, inside described steel pipe bored concrete pile lower end, be perfused with concrete embedded rock pile, described mixed
Solidifying soil embedded rock pile lower end passes steel pipe bored concrete pile lower end build-in in preventing seabed base rock stratum.
Further, described blower fan tower barrel is installed on steel pipe single pile upper end through adpting flange.
Further, described steel pipe bored concrete pile is by being fixedly welded on steel pipe single pile；The diameter of described steel pipe single pile is big
In 5m, a length of 30 ~ 100m, the described a diameter of 1.5 ~ 3m of steel pipe bored concrete pile.
Compared with prior art, this utility model has the advantages that this utility model offshore wind farm embedding rock single pile
Base structure is novel, reasonable in design, efficiently solves the most domestic difficulty that cannot realize the construction of large diameter pile foundation tunneling boring embedding rock
Topic, the minor-diameter steel-tube bored concrete pile simultaneously circumferentially increased greatly strengthen the integral rigidity of base structure, improves pile foundation
Its ultimate bearing capacity and resistance to capsizing, reduce pile body displacement, reduce the dynamic response of base structure, improves construction effect
Rate, expands the scope of application of single-pile foundation, has high using value.
For making the purpose of this utility model, technical scheme and advantage clearer, specific embodiment below will be passed through
And relevant drawings, this utility model is described in further detail.
