The about key factor of offshore wind farm exploitation.
Offshore wind power foundation structural shape is varied, including many pile leaders frame, single pile, spider basis, gravity type base
Plinth, cylindrical foundation and floatation type basis etc..Due to single pile simple in construction, stress is clear and definite, and short construction period, is in Practical Project
Most widely used foundation pattern.
Single-pile foundation is generally made up of single large diameter steel pipe, and bottom is goed deep in soil, it is provided that bearing capacity.It is applicable to cover layer
The preferable marine site of thicker and topsoil, shallow overburden needs the construction of embedding rock.The single-pile foundation construction cycle is short, and construction is affected by weather
Little, but injection in place for super-large diameter single pile must possess large-scale sinking apparatus, and perpendicularity is required the highest by single pile, embedding rock
During construction, difficult construction degree is relatively big, considerably increases cost.
Utility model content
The purpose of this utility model is to overcome drawbacks described above, it is provided that a kind of difficulty of construction is little, the sea turn that cost is low
Electricity foundation columns pilework.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of offshore wind power foundation stanchion structure, including single pile and plural steel-pipe pile, the diameter of described single pile is big
In the diameter of steel-pipe pile, steel-pipe pile more than said two is parallel to each other and is connected to the lower surface of single pile, and described steel-pipe pile divides
Cloth is in the circumference range of single pile.
Further, described steel-pipe pile is embedding rock formula stake or driving into type stake.
Further, described steel-pipe pile upper end is coupled by armored concrete with bottom single pile.
Further, described steel-pipe pile upper end is coupled by steel construction with bottom single pile.
Further, described steel-pipe pile upper end is coupled by combinative structure with bottom single pile.

Belong to coating.
Further, a diameter of more than 2.0m of described single pile, a diameter of more than 0.6m of described steel-pipe pile.
The beneficial effects of the utility model are: the sea turn that many steel-pipe piles of this utility model combine with large-diameter pile
Electricity base structure, large diameter steel pipe pile is after pile sinking reaches certain depth, in the case of continuation pile sinking difficulty is very big, if using
Dry small diameter steel pipe piles instead of large diameter steel pipe pile, continues pile sinking, owing to the pile sinking of little steel-pipe pile larger diameter steel-pipe pile is difficult
Spend less, and small diameter steel pipe piles can effectively contact soil, produce frictional resistance and end resistance is little, to the raising of bearing capacity power and
Control pile body sedimentation and have the biggest contribution.This base structure reduces piling construction difficulty, and the cycle is short, good in economic efficiency.

Mode also coordinates accompanying drawing to be explained in detail.
The design of this utility model most critical is: uses some small diameter steel pipe piles to instead of large diameter steel pipe pile and sinks
Stake, reduces piling construction difficulty, and the cycle is short, good in economic efficiency.
Referring to shown in Fig. 1 to Fig. 2, the offshore wind power foundation stanchion structure of the present embodiment, including single pile 1 and two or more
Steel-pipe pile 2, the diameter of described single pile 1 is more than the diameter of steel-pipe pile 2, and steel-pipe pile 2 more than said two is parallel to each other and connects
Being connected on the lower surface of single pile 1, described steel-pipe pile 2 is distributed in the circumference range of single pile 1.
Work process of the present utility model is: small diameter steel pipe piles 2 is after large-diameter pile 1 is driven into certain depth, clearly
Manage 1 interior soil body of big single pile, then in large-diameter pile 1 body, squeeze into small diameter steel pipe piles 2, small diameter steel pipe piles from top to bottom
2 extend into large-diameter pile 1 certain length couples.
Knowable to foregoing description, the beneficial effects of the utility model are: many steel-pipe piles 2 of this utility model and major diameter
The offshore wind power foundation structure of single pile 1 combination, large diameter steel pipe pile 2, after pile sinking reaches certain depth, continues pile sinking difficulty non-
In the case of the biggest, use some small diameter steel pipe piles 2 to instead of large diameter steel pipe pile 2, continue pile sinking, due to little steel-pipe pile 2
The pile sinking difficulty of larger diameter steel-pipe pile 2 is less, and small diameter steel pipe piles 2 can effectively contact soil, produces frictional resistance and end resistance
Power is little, and raising and control pile body sedimentation to bearing capacity power have the biggest contribution.It is difficult that this base structure reduces piling construction
Degree, and the cycle is short, good in economic efficiency.
