Problems solved by technology

However, the first and second types are uneconomical, costly and time-consuming, and the effect is not obvious
The third method is to increase the amount of steel used in the caisson, which undoubtedly increases the cost and is uneconomical

Abstract

The invention discloses an assembled gravity type flanged suction caisson foundation which comprises a flanged suction caisson foundation, wherein the bottom of the flanged suction caisson foundationis provided with an opening; the top of the flanged suction caisson foundation is provided with a sealing cover; the sealing cover is provided with a steel column, a steel sleeve and a drainage channel; a plurality of precast concrete weight blocks are sequentially stacked up on the flanged suction caisson foundation; the top of each of the precast concrete weight blocks is provided with a truncated-cone-shaped convex groove; the bottom of each of the precast concrete weight blocks is provided with a truncated-cone-shaped concave groove; every two adjacent precast concrete weight blocks are connected to each other in an engaged manner and stacked up through the corresponding truncated-cone-shaped convex groove and the corresponding truncated-cone-shaped concave groove; the upper part of the side of the flanged suction caisson foundation is provided with flange plates or a ring-shaped flange; the drainage channel communicates with the inner cavity of the flanged suction caisson foundation through the steel sleeve; and the diameter of each of the precast concrete weight blocks is greater than or equal to the diameter of the flanged suction caisson foundation. The vertical and horizontal bearing capacity of the suction caisson foundation can be greatly improved by virtue of the flange plates and the self weight of concrete.

Description

technical field [0001] The invention relates to the technical field of anchoring of floating offshore wind turbines, in particular to an assembled gravity-type winged suction-type caisson foundation. Background technique [0002] Most of the global offshore wind power is within a range of less than 50m. The development of resources in the deep sea is in the exploratory stage. The application of traditional fixed wind turbines to wind power in the deep sea will inevitably cause disadvantages such as high cost and difficult construction. Therefore, replacing traditional fixed wind turbines with floating offshore wind turbines has become the direction of future wind power development. [0003] The suction caisson foundation is a new type of foundation form for deep-sea offshore platform structures, which meets the needs of wind turbine construction in the deep-sea field. Compared with the traditional pile foundation, the suction caisson foundation has the advantages of conveni...
