Offshore wind power large-diameter bionic bamboo joint steel pipe pile of integrated damping shock absorber

Abstract

The invention discloses an offshore wind power large-diameter bionic bamboo joint steel pipe pile of an integrated damping shock absorber. The offshore wind power large-diameter bionic bamboo joint steel pipe pile of the integrated damping shock absorber comprises a steel pipe pile body, a transverse bearing component and a damping shock absorber, the lower portion of the steel pipe pile body is driven into the seabed, and a frame component of the transverse bearing component is located in the steel pipe pile body on the lower portion of the seabed and connected with the steel pipe pile body on the lower portion of the seabed. A flat plate component of the transverse bearing component is located in the steel pipe pile body on the upper portion of the seabed and connected with the steel pipe pile body on the upper portion of the seabed, the damping shock absorber is arranged on the flat plate component in the steel pipe pile body or the inside of the steel pipe pile body, and the steelpipe pile body and the transverse bearing component form the bionic bamboo joint steel pipe pile. According to the offshore wind power large-diameter bionic bamboo joint steel pipe pile of the integrated damping shock absorber, the problems that an offshore wind power large-diameter steel pipe pile is prone to bending damage and buckling damage, large in vibration response and high in manufacturing cost are solved. According to the bionic bamboo joint design, the bending strength and buckling resistance of the steel pipe pile are improved, deformation in the transportation process is avoided,the vibration frequency of a single pile foundation is reduced through the damping shock absorber, the resonance and vortex vibration of the foundation, a tower drum and a unit are avoided, and the characteristics of being easy to manufacture, low in cost and good in stability are achieved.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power pile foundations, and relates to an offshore wind power large-diameter bionic bamboo-jointed steel pipe pile integrated with a damping shock absorber. Background technique [0002] At present, domestic 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 process, and short construction period. It is the most commonly used foundation type for offshore wind farms with a water depth of less than 30m. Type accounts for more than 80%. With the further development of offshore wind power development, the water depth of offshore wind farms will increase from 30m to more than 60m, the unit capacity will reach 15MW, and the diameter of wind...
