Description

Jacket steel bucket foundation
Technical field
The utility model relates to a kind of jacket steel bucket foundations.It is led suitable for wind power industry civil engineering technology Domain.
Background technique
China possesses very long coastline, and sea area, which is contained, wind energy resources abundant, currently, Jiangsu, Zhejiang, Shanghai, wide The maritime provinces such as east, Hebei, Fujian have all formulated respective offshore wind farm development plan, and begin with part marine wind electric field and go into operation Construction.With the support energetically of national policy, China's offshore wind farm construction process is accelerated, and China coast Wind Power Generation Industry develops at present More rapidly.
With the development of offshore wind farm industry, the region that offshore distance is close, the depth of water is shallower is developed totally substantially, and wind-powered electricity generation is more next More develop toward deep-sea direction, due to the characteristic of China mainland frame, within the scope of certain continental shelf, the depth of water substantially still in 50m hereinafter, And shallow-layer geological conditions is general, considers that the convenience of economy and construction, bucket foundation become a kind of novel Wind turbines Foundation structure form, built model machine engineering shows using the foundation pattern at present, when running of wind generating set the rigidity of structure compared with Greatly, stability is good, substantially without friction.
Concrete structure is used on the basis of traditional compound cartridge type, with water depth increases, using concrete structure figure It is more and more huger, difficulty of construction is further increased, and horizontal fan load and Moment are larger, concrete, which is easy to produce, to be split Seam, will cause the damage of unrepairable, and problem is more prominent.
Summary of the invention
Technical problem to be solved by the utility model is: in view of the above problems, provide that a kind of structure is simple, construction The jacket steel bucket foundation convenient, cost is relatively low, safe and reliable.
The technical scheme adopted by the utility model is a kind of jacket steel bucket foundation, it is characterised in that: including big Diameter thin-wall steel pipe, steel top plate, jacket and cylinder, wherein large diameter thin wall steel cylinder is fixed on sea bed vertically, this is big straight The fixed steel top plate in the top of diameter thin-wall steel pipe is simultaneously blocked through steel top plate, and steel top plate is fixed with jacket, conduit on top surface The upper end of frame is fixedly connected with the cylinder coaxially arranged with large diameter thin wall steel cylinder through strut, and barrel top is equipped with connecting flange.
The jacket has more equally distributed supervisors, and the steel top plate is fixed on through terminal pad in the lower end of supervisor On, it is connected between supervisor and supervisor through diagonal brace.
It is connected between the supervisor lower end and adjacent supervisor lower end through connecting plate, connecting plate is fixed on the steel top plate On.
The strut and the supervisor, which correspond, to arrange, one end of the strut, which is fixed on, is responsible for top, strut it is another End is fixed on the side wall of the cylinder.
The jacket top is equipped with steel platform.
The beneficial effects of the utility model are: the utility model uses large diameter thin wall steel cylinder, steel top plate and jacket Deng being used as blower foundation, it can be adapted for the coastal waters of the depth of water relatively deep (being greater than 15m), effective less bucket foundation weight, compared with Shaohai The difficulty such as upper construction transport, and avoid using working procedures such as grouting waterborne.The supervisor of steel pipe frame is through even in the utility model It connects disk and connecting plate is fixed on steel top plate, structure is simple, can preferably adapt to subsea environment, improves the safe and reliable of connection Property.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment 1.
Fig. 2 is the top view of embodiment 1.
Fig. 3 is the top view of embodiment 2.
Specific embodiment
Embodiment 1: as shown in Figure 1 and Figure 2, the present embodiment is a kind of jacket steel bucket foundation, including large diameter thin wall Steel cylinder 1, steel top plate 2, jacket 3 and cylinder 8, wherein large diameter thin wall steel cylinder 1 is fixed on sea bed vertically, and the major diameter is thin The fixed steel top plate 2 in the top of wall steel cylinder is simultaneously blocked through steel top plate 2, and top plate blocks and is fixed with jacket 3, jacket on top surface 3 upper end is fixedly connected with the cylinder 8 coaxially arranged with large diameter thin wall steel cylinder 1 through strut 7, is equipped with connecting flange at the top of cylinder 8 9。
Jacket 3 has 4 equally distributed supervisors 301 in this example, and steel is fixed on through terminal pad 5 in the lower end for being responsible for 301 On matter top plate 2, it is responsible between 301 lower ends and 301 lower ends of adjacent supervisor and is connected through connecting plate 4, connecting plate 4 is fixed on steel top plate On 2, an entirety is connected into through diagonal brace 302 between supervisor 301 and supervisor 301.
Every supervisor 301 is corresponded in the present embodiment and is equipped with a strut 7, and corresponding supervisor's 301 be fixed in one end of strut 7 Top, the other end of strut 7 are fixed on the side wall of cylinder 8.
Large diameter thin wall steel cylinder 1 is the thin-wall steel pipe of diameter 20m~40m, 15~25mm of thickness in the present embodiment.Major diameter Multiple equally distributed separation storehouses are separated to form through steel plate in thin-wall steel pipe 1, steel top plate 2 is equipped with the corresponding centrifugation for separating storehouse The bucket foundations such as pump take out the equipment such as negative pressure, leveling.
Embodiment 2: it as shown in figure 3, the present embodiment is substantially the same manner as Example 1, the difference is that only in the present embodiment Jacket 3 has 3 equally distributed supervisors 301.
Certainly, above description is not limitation of the utility model, and the utility model is also not limited to the example above, this skill The those of ordinary skill in art field, in the scope of the utility model, variation, addition or the replacement made all should belong to this reality With novel protection scope.
