Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Reference is made to the accompanying drawings. The offshore wind power foundation of this embodiment includes suction bucket 1, umbelliform backplate 3, backup pad 4 and hollow steel pipe single pile 2. Wherein, the opening of the suction bucket 1 is arranged downwards. The umbrella-shaped guard plate 3 covers the suction barrel 1 and comprises a conical main body 30 and a vertical plate 31 connected to the lower edge of the conical main body 30 and vertically arranged, the conical main body 30 completely covers the top of the suction barrel 1, and therefore the conical main body 30 can play a role in preventing scouring. When the umbrella is installed and used, the vertical plate 31 is penetrated into the base to prevent water flow from entering the umbrella-shaped guard plate 3. Specifically, the vertical plate 31 is positioned below the top of the suction bucket 1, and the included angle between the side surface of the conical main body 30 and the axis is 45 degrees. The supporting plate 4 is in a shape of a frustum with an upper opening 40 having a diameter larger than a lower opening 41, wherein the upper opening 40 is vertically connected to the inner wall of the conical body 30 at an angle of 90 degrees, and the lower opening 41 is connected to the top surface of the suction barrel 1 at an angle of 45 degrees, so that the umbrella-shaped protecting plate 3 is connected to the suction barrel 1. The hollow steel pipe single pile 2 sequentially penetrates through the top surface of the suction barrel 1, the lower end opening of the supporting plate 4, the upper end opening of the supporting plate 4, the top of the umbrella-shaped guard plate 3 and the outer wall of the umbrella-shaped guard plate 3 to be connected with the penetrating openings of the suction barrel 1 and the umbrella-shaped guard plate 3.
Particularly, the top surface of the suction bucket 1 is also provided with a drain hole 5 and a reinforcing rib plate 6, the reinforcing rib plate 6 divides the top surface of the suction bucket 1 into a plurality of areas, and the drain holes 5 are respectively and correspondingly arranged in the areas. The support plate 4 comprises a steel plate 7 and a concrete filling 8.
