Embodiment Construction

[0027] Such as Figure 1~Figure 5 Among them, a diagonally braced offshore wind power monopile foundation with a damping sleeve, which includes a pile body 1, a damping sleeve 2, a diagonal brace 3, a damper 4, and a rotating shaft 5; the diagonal brace 3 and the damping sleeve 2 connection, a plurality of braces 3 are arranged radially in a circular shape along the outer wall of the damping sleeve 2; the damper 4 is arranged inside the damping sleeve 2, and the rotating shaft 5 is connected with the damping sleeve 2 and the damper 4; The direction is consistent with the axial direction of the pile body 1; a filler is arranged between the damping sleeve 2 and the pile body 1; and the damper 4 moves in translation in four directions. The structure is simple. During construction, a plurality of diagonal braces 3 are arranged radially in a ring along the outer wall of the damping sleeve 2. The viscous damper is arranged inside the damping sleeve 2 and connected with the rotating ...

Abstract

The invention discloses an inclined strut offshore wind power single pile foundation with a damping sleeve and a construction method. The inclined strut offshore wind power single pile foundation comprises a pile body, the damping sleeve, inclined struts, dampers and a rotating shaft. The multiple inclined struts are annularly and radially arranged along the outer wall of the damping sleeve, the viscous dampers are arranged in the damping sleeve and connected with the rotating shaft, and four-direction translation is achieved; the axis direction of the damping sleeve is consistent with the axis direction of the pile body, the space between the damping sleeve and the pile body is filled with the cement rubber particles, elastic contact is guaranteed, and meanwhile, the pile body is prevented from being separated from the damping sleeve under cyclic loads. The structure is simple, the inclined struts surround the lower portion of the mud surface around the foundation, the diameter of the pile body is reduced, the horizontal bearing capacity and stability of the pile body are guaranteed, horizontal lateral inclination of the pile body is avoided, installation is convenient and fast, and operation is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power, and relates to a diagonally braced offshore wind power single pile foundation with a damping sleeve and a construction method. Background technique [0002] Offshore wind power foundation structures are mainly based on single pile foundations, jacket foundations, high pile cap foundations, and barrel foundations. The single pile foundation is a large-diameter steel pipe pile, which has the advantages of clear structural force, simple manufacturing and construction technology, and short construction period. It is the most commonly used foundation type for offshore wind farms with a water depth below 30m. The basic type accounts for more than 60%. With the further development of offshore wind power, the water depth of offshore wind farms will increase from 30m to 60m. At the same time, in order to meet the needs of large-capacity units for the bearing capacity of supporting structures,...
