Abstract
The utility model relates to a prefabricated reinforced concrete-caisson-type offshore wind turbine foundation structure, which is simple in structure, safe, reliable and easy to construct, and realizes reduction of steel consumption and construction cost. The prefabricated reinforced concrete-caisson-type offshore wind turbine foundation structure comprises an annular inner cylinder and an annular outer cylinder which are made of reinforced concrete and arranged coaxially; the height of the outer cylinder is less than the height of the inner cylinder; the top of the outer cylinder is connected with the outer wall of the inner cylinder through top plates; spoke-shaped partition walls are disposed between the outer wall of the inner cylinder and the outer cylinder; the partition walls, the inner cylinder, the outer cylinder and the top plates form a plurality of enclosed compartments; and the top plates corresponding to the compartments are provided with operation holes. The prefabricated reinforced concrete-caisson-type offshore wind turbine foundation structure is applicable to the field of offshore wind power generation.
Description
Technical field
The utility model relates to a kind of prefabricated reinforced concrete caisson type offshore wind generating foundation structure.Be applicable to the Oversea wind power generation field.
Background technology
In China, Oversea wind power generation is an emerging industry.China begins progressively to develop the Oversea wind power generation industry after 2007, and existing at present a small amount of marine wind electric field puts into operation, and along with the enforcement of China's energy strategy from now on, offshore wind farm will be developed fast.
Because the particularity of marine natural environment, common land construction machinery and job practices can not be used, and the wind driven generator base structure of land routine can not be used for the sea.Domestic in recent years, abroad also studied and used some and be applicable to the structural shape on offshore wind generating basis; Single pile basis is generally arranged, jacket is basic, highrise pile cap is basic, gravity type foundation etc.; These bases or need to consume a large amount of steel and cause construction cost expensive, or ground had relatively high expectations and be not suitable for China's Coastal Areas.
Summary of the invention
The technical problem that the utility model will solve is: to the problem of above-mentioned existence; A kind of prefabricated reinforced concrete caisson type offshore wind generating foundation structure of simple in structure, safe and reliable, easy construction is provided; To scheme to reduce steel consumption, reduce construction cost.
The technical scheme that the utility model adopted is: a kind of prefabricated reinforced concrete caisson type offshore wind generating foundation structure; It is characterized in that: said foundation structure system is made up of the annular inner core and the urceolus of steel concrete material, coaxial arrangement; High and urceolus top is connected with inner tank theca through top board in the inner core tube in urceolus tube higher primary school; Be provided with the partition wall of spoke-like between inner tank theca and the urceolus; This partition wall, inner core, urceolus and top board surround the separation of several sealings, leave handle hole on the pairing top board of each separation.
Said inner core inside is provided with prestress wire, and the prestress wire top links to each other with basic flange, and the other end extend into the bottom of inner tube wall always.
The outside at said inner core top connects outer inspection platform, and the inwall of inner core is provided with interior inspection platform.
The beneficial effect of the utility model is: the separation that 1, forms a plurality of sealings between inner core, urceolus, partition wall and top board; Because infiltrating separation, empty G&W needs the regular hour; Bear the moment of flexure that unit transmits and when rotating distortion, will in separation, form certain negative pressure when the basis, this negative pressure can be resisted the moment of flexure in short-term that part of generating units transmits; Therefore can save key dimension, save construction investment.2, reinforced concrete structure is adopted on whole basis, compares with traditional steel work basis, has saved a large amount of steel, has therefore saved construction investment.3, reinforced concrete structure is adopted on whole basis, compares with traditional steel work basis, and sea water corrosion resistant is better, and basic reliability is better.4, whole basis is prefabricated by land, at sea disposable sinking put, and convenient, the cycle weak point of constructing has been saved a large amount of ship machine equipments.
Description of drawings
Fig. 1 is the sectional drawing of the utility model.
Fig. 2 is the plan view of the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2; Present embodiment is basically in the natural conditions in the coastal marine site of China; Proposed a kind ofly to be applicable to 0 ~ 20m depth of water, to be applicable to chiltern or shale ground, and prefabricated reinforced concrete caisson type offshore wind generating foundation structure cheap, reliable, easy construction.This foundation structure is made up of inner core 1, urceolus 2 and partition wall 3, and wherein inner core 1 is the steel hoop concrete structure with urceolus 2, and inner core 1 is higher than urceolus 2.Inner core 1 and urceolus 2 coaxial arrangement in this example, the partition wall 3 that both arrange through spoke-like connects, and urceolus 2 tops also are connected with inner core 1 through the top board 21 of horizontal arrangement.This partition wall, inner core, urceolus and top board surround the separation of several sealings, leave handle hole 22 on the pairing top board of each separation.Said handle hole 22 is used for construction period and advances people, draining and ventilation, after immerge is in place, and handle hole 22 sealings.
Be provided with prestress wire 12 in inner core 1 inside in the present embodiment, prestress wire 12 reaches the bottom of inner core 1 always, and the top of prestress wire 12 links to each other with basic flange 13, and basic flange 13 can be connected with end flanges under the wind-power generating unit tower.The outside at inner core 1 top is provided with outer inspection platform 11 in this example, and the inwall of inner core 1 is provided with interior inspection platform 14, and interior inspection platform 14 can be used for laying tower tube bottom equipment and makes things convenient for the tower tube to install.
Prefabricated reinforced concrete caisson type offshore wind generating foundation structure described in the present embodiment, be accomplish by land integral prefabricated, be transported to the scene through barge after, through deadweight and hydraulic sinking, heavyly put back in place wind power generating set be installed on the basis.
