Description
Technical field
The utility model relates to a kind of single pile formula 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 single pile formula steel bucket foundation convenient, cost is relatively low, safe and reliable.
The technical scheme adopted by the utility model is a kind of single pile formula steel bucket foundation, it is characterised in that: including by
It is lower and on sequentially coaxially connected large diameter thin wall steel cylinder, steel top plate, circular arc steel cylinder and cylinder, wherein large diameter thin wall steel cylinder
It is fixed on sea bed vertically, the fixed steel top plate in the top of the large diameter thin wall steel cylinder simultaneously blocks, the circular arc through steel top plate
Steel cylinder lower end outer diameter is adapted with the steel top plate, and circular arc steel cylinder upper end outer diameter is adapted with the cylinder, the circular arc steel cylinder
By lower end to upper end, its outer diameter is gradually reduced, and the cylinder top is formed with connecting flange.
The large diameter thin wall steel cylinder is having a size of diameter 20m~40m, 15~25mm of thickness；The drum diameter be 4~
8m, 40~100mm of thickness.
Multiple equally distributed separation storehouses are separated to form through steel plate in the large diameter thin wall steel cylinder.
The barrel top is equipped with steel platform.
The beneficial effects of the utility model are: the utility model undertakes top fan loads using large diameter thin wall steel cylinder,
The feature that blower foundation vertical force is small, horizontal force and horizontal bending moment are big is adapted to, effective less structural steel amount is further reduced cylinder
Type basis weight, the difficulty such as less offshore construction transport.The utility model realizes major diameter by steel top plate and circular arc steel cylinder
The transition of thin-wall steel pipe and cylinder connects, and structure is simple, and connection is reliable.The shape of circular arc steel cylinder can be preferably in the utility model
Subsea environment is adapted to, the appearance of stress concentration is avoided, improves the security reliability of connection.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment.
Fig. 2 is the top view of embodiment.
Specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment is a kind of single pile formula steel bucket foundation, including large diameter thin wall steel cylinder 1, steel
Matter top plate 2, circular arc steel cylinder 3 and cylinder 4, wherein large diameter thin wall steel cylinder 1 is fixed on sea bed vertically, the large diameter thin wall steel cylinder
The fixed steel top plate 2 in top and blocked through steel top plate 2, top plate block is fixed on top surface it is same with large diameter thin wall steel cylinder 1
The circular arc steel cylinder 3 of axis arrangement, the upper end of circular arc steel cylinder 3 is with cylinder 4 is connected with, and cylinder 4 and circular arc steel cylinder 3 are weldingly connected or one
It is made, is terminated on cylinder 4 for the connecting flange with 6 bottom flanged joint of tower, it can be according to Wind turbines need at the top of cylinder 4
Seek setting steel platform 5.
Multiple equally distributed separation storehouses, steel top are separated to form through steel plate in large diameter thin wall steel cylinder 1 in the present embodiment
Plate 2 is equipped with the bucket foundations such as the corresponding centrifugal pump for separating storehouse and takes out the equipment such as negative pressure, leveling.
Thin-wall steel pipe of the large diameter thin wall steel cylinder 1 having a size of diameter 20m~40m, 15~25mm of thickness in this example；Cylinder 4
Size is mating with tower, and diameter is 4~8m, and thickness uses 40~100mm according to fatigue load.
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
