Unit has been researched and developed successfully and has progressively put into application, uses traditional single pile pattern, the diameter of stake and wall thickness to dramatically increase, its
Diameter is likely to be breached more than 10 meters, has both added cost, simultaneously because the shortage of super-large diameter pile driving equipment, can smooth construction
It is implemented as the key of its application.
Summary of the invention:
The purpose of this utility model is to provide circular combined super-large diameter offshore wind farm single-pile foundation, this single-pile foundation
Efficiently solve a difficult problem for super-large diameter single pile construction and installation, significantly enhance the control action to horizontal displacement simultaneously,
Improve the load-carrying properties on basis, greatly reduce the horizontal displacement of structure, increase diameter or thickness relative to simple, have more
Good economic benefit and application prospect.
This utility model circular combined super-large diameter offshore wind farm single-pile foundation, it is characterised in that: include mutually being nested with
The first single pile and the second single pile, described first, second single pile is steel-pipe pile, if two single piles are by being located between the two
Dry junction steel plate one annular of welding formation is overall.
Further, above-mentioned first single pile diameter is less than 8 meters, a diameter of 8 meters of described second single pile, 9 meters or bigger.
Further, above-mentioned first single pile a length of 30-100 rice, described second single pile outside the first single pile, its top
Highly less than the first single pile, junction steel plate upper end extends to the first single pile top and plays distortion, and the second single pile bottom is comparable
First single pile is short, and junction steel plate lower end can make stiffener pattern equally.
Further, above-mentioned junction steel plate is 3,4,5 or more.
Further, the space formed with junction steel plate between above-mentioned two single piles is perfused with concrete or embedding rock concrete
Stake.
The construction technology of this utility model circular combined super-large diameter offshore wind farm single-pile foundation, described circular combined
Super-large diameter offshore wind farm single-pile foundation includes the first single pile and the second single pile being mutually nested with, and described first, second single pile is equal
For steel-pipe pile, two single piles form an annular entirety by several junction steel plates welding being located between the two；Construction step
Rapid:
1), after the accurate setting-out of factory, the first single pile and the second single pile are made, single by junction steel plate welding first, second
Stake is combined into entirety；
2) site operation marine site determines this place, basis installation site；
3) prefabricated single-pile foundation being transported to relevant position, lifting is had good positioning；
4) arrange pile driving equipment on the first single pile top, the first single pile carries out piling operation, then this single-pile foundation is overall
Squeeze into sea bed accordingly；
5) silt particle within annular space that cleaning single-pile foundation is formed, is irrigated concrete or boring pours into embedding rock
Stake；
6) in the first single pile upper end, blower fan tower barrel is installed.
This utility model gives a kind of novel offshore wind farm super-large diameter single-pile foundation pattern, by large-diameter pile
(the first single pile) is welded and fused by junction steel plate with super-large diameter single pile (the second single pile), only hits major diameter during piling
Single pile (the first single pile), squeezes into sea bed by the junction steel plate of annular space together by super-large diameter single pile (the second single pile).Beat
After entering certain depth, penetration concrete or several according to actual demands of engineering choice arrangement in the multiple annular spaces separated
Embedding rock paxilla, need not penetration concrete or embedding rock in large-diameter pile, greatly subtract while increasing basis integral rigidity
Little concrete amount.Meanwhile, this basis efficiently solves the difficult problem that super-large diameter pile foundation construction is installed, and improves pile foundation water
Flat bearing capacity and resistance to capsizing, reduce the dynamic response of base structure, expands the scope of application of single-pile foundation, makes
The most jumbo Wind turbines of 6MW, 8MW uses single pile to be possibly realized.Therefore, this base case has high engineering in fact
Border using value.
