Description

A kind of novel suction cartridge type composite structure wind power foundation suitable for shallow sea
Technical field
The present invention relates to technical field of wind power generation.
Background technique
The wind-powered electricity generation energy is a kind of pollution-free, reproducible clean energy resource.China's offshore wind speed is abundant, offshore wind farm and land On compare, wind turbine power generation amount is higher, runs more stable, and is not take up land resource, therefore offshore wind farm is China's wind power new energy Following important development direction.
China sea area is mostly the unfavorable foundations such as bury and flour sand, and bearing capacity is lower, stability is poor, and marine wind environment Complexity often faces the extreme sea conditions such as typhoon, and Limit of Wind Speed is larger, and traditional foundation structure form is by very big challenge.Therefore, it grinds It is good to send out stability a kind of, and resistance to capsizing is strong, suitable for unfavorable foundation soil property and novel offshore wind power foundation easy for construction, is Very necessary.
Summary of the invention
The present invention proposes a kind of novel suction cartridge type composite structure wind power foundation suitable for shallow sea: the system includes center Stake, suction tube, barrel, top cover divide storehouse plate, steel ribbed stiffener, tower linkage section and peg.The system has given full play to composite structure Advantage, reasonable stress, stability is good, and resistance to capsizing is strong, is suitable for unfavorable foundation soil property, compared to traditional steel construction suction tube Basic steel using amount is lower, easy for construction, has wide future in engineering applications.
Technical scheme is as follows:
A kind of novel suction cartridge type composite structure wind power foundation suitable for shallow sea, the system include central post, suction tube, Barrel, top cover divide storehouse plate, steel ribbed stiffener, tower linkage section and peg.
Suction tube is enclosed by barrel and top cover, and three pieces of points of storehouse plates are arranged in cylinder and form suction tube cavity, is utilized Three cavity pressure differences adjust base water Pingdu.Barrel, top cover and a point storehouse plate are all made of double-layer plate concrete, and steel plate connects with concrete Side weld stud is touched to reinforce connecting.The bottom end of barrel is made into pointed to be inserted into sea bed soil layer.
Central post using solid steel tube concrete or empty steel pipe, stake top, stake side respectively with top cover, that a point storehouse plate is connect is firm. The bottom end of central post is made into pointed to be inserted into sea bed soil layer.
Tower linkage section is arranged in top cover top, and tower linkage section is below seawater face using real in 1/2~2/3 altitude range Heart concrete filled steel tube.Top cover top circumferentially arranges that steel ribbed stiffener, steel ribbed stiffener are closely connect with top cover and tower linkage section.
The present invention has the advantages that compared with the existing technology
(1) combined structure system is used in basis, bearing capacity is high, and it is easy for construction, compared to traditional steel construction suction tube base Plinth steel using amount is lower, saving construction cost.
(2) in combination with two kinds of basic advantages of suction tube and single pile: soil body collective effect in suction tube and cylinder, favorably In resisting horizontal loading and deformation, reduce differential settlement；Central post can provide biggish pile side friction and end resistance, energy It effectively improves vertical bearing capacity and reduces vertical deformation；By being reliably connected to form entirety, common stress and deformation have the two Higher bearing capacity and resistance to capsizing.The foundational system can play good effect in the unfavorable foundation soil property in sea area.
(3) tower linkage section uses solid steel tube concrete below seawater face in 1/2~2/3 altitude range, can be improved Overall structure rigidity；Top tower load Transmit evenly is conducive into base to basis by the steel ribbed stiffener circumferentially arranged Plinth plays one's part to the full.
