Description
Technical field
The utility model relates to a kind of offshore wind turbine single-pile foundation integrated form accessory structure.Be applicable to Oversea wind power generation industry.
Background technique
Along with reaching its maturity of wind generating technology, the mode relying on wind-power electricity generation to increase energy supply is subject to the favor of countries in the world gradually.Wide ocean has abundant, stable wind energy resources because of it, attracts attention already.China has very long shore line, marine site is contained abundant wind energy resources, at present, the maritime provinces such as Hebei, Shandong, Jiangsu, Zhejiang, Shanghai, Guangdong, Fujian have all formulated offshore wind farm development plan, and wherein Jiangsu Province has marine wind electric field demonstrative project and to put into operation and power generation.
Single-pile foundation is as a kind of foundation pattern the most extensively adopted in offshore wind farm engineering, and its structure is simple, quick construction, cost performance are high; The steel pipe pile of general employing diameter 4 ~ 6m vertically squeezes into sea bed, and is connected with top blower fan tower barrel by changeover portion, is connected between changeover portion with steel pipe pile by high-strength grouting material.Find through field monitoring in recent years, occur between the single-pile foundation high-strength grouting material of external part offshore wind turbine and changeover portion coming to nothing and the unfavorable phenomenon such as vertical displacement, there is certain potential safety hazard.
For avoiding the engineering safety risk caused because of high-strength grouting material Joint failure, applicant has invented a kind of without changeover portion single pile formula offshore wind turbine foundation structure (patent No.: ZL 2,012 1 0114192.X), this fondational structure eliminates changeover portion, not only have that structure is simple, outside quick construction, cost performance advantages of higher, also eliminate the risk of Joint failure between high-strength grouting material and steel pipe pile; The Accessory Members such as shortcoming is fender system, cable trunk, sacrificial anode all weld on the body construction, and installation difficulty is large, easily produce piling and destroy.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, there is provided that a kind of structure is simple, the offshore wind turbine single-pile foundation integrated form accessory structure of easy construction, to reduce Accessory Members installation difficulty, save the offshore construction activity duration, eliminate Accessory Members piling and destroy equivalent risk.
The technological scheme that the utility model adopts is: a kind of offshore wind turbine single-pile foundation integrated form accessory structure, is characterized in that: this accessory structure integral assembling on single-pile foundation, and is supported on the support bracket of single-pile foundation bottom stake surface programming;
Described accessory structure comprises blower fan outer platform, cable protection pipe, fender system, sacrificial anode and some collar tie beams be set on single-pile foundation, described collar tie beam and collar tie beam keep at a certain distance away, concentric coaxial arrangement, are connected for overall between collar tie beam and between collar tie beam with blower fan outer platform through cable protection pipe, fender system and some collar tie beam struts; Described sacrificial anode is welded on bottom collar tie beam or the bottom of collar tie beam strut.
Space between described collar tie beam and single-pile foundation adopts some pieces of wedge steel discs to clog closely.
The beneficial effects of the utility model are: 1) Accessory Members such as fender system, blower fan outer platform, cable protection pipe and sacrificial anode are become one by collar tie beam and collar tie beam strut by the utility model, reduce Accessory Members installation difficulty, decrease the offshore construction activity duration, reduce offshore lifting cost, economic benefit is obvious; 2) the utility model effectively can evade the flutter failure of piling pile body Accessory Members, is particularly useful for without changeover portion single-pile foundation.
