Abstract

A diagonal bracing offshore wind power single pile foundation with a damping sleeve and its construction method, which includes a pile body, a damping sleeve, a diagonal brace, a damper and a rotating shaft, and a plurality of diagonal braces are formed in a circular radial shape along the outer wall of the damping sleeve Layout, the viscous damper is arranged inside the damping sleeve and connected with the rotating shaft to achieve four-way translation. The axial direction of the damping sleeve is consistent with the axial direction of the pile body, and cement rubber particles are filled between the damping sleeve and the pile body to ensure Elastic contact while avoiding separation of the pile body from the damping sleeve under cyclic loads. The invention has a simple structure, and the diagonal bracing surrounds the lower part of the mud surface around the foundation, which is beneficial to reduce the diameter of the pile body, ensures the horizontal bearing capacity and stability of the pile body, avoids the horizontal tilting of the pile body, is convenient and quick to install, and is simple and convenient to operate.

Description

Technical field [0001] The present invention belongs to the field of offshore wind power technology, relates to a diagonal bracing offshore wind power monopile foundation with a damping sleeve and a construction method. Background [0002] The offshore wind power infrastructure is mainly monopile foundation, conduit frame foundation, high pile pile pile foundation, and barrel foundation. The single pile foundation is a large-diameter steel pipe pile, which has the advantages of clear structural stress, simple production and construction process, short construction period, etc., and is the most commonly used foundation type for offshore wind farms with a water depth of less than 30m, accounting for more than 60% of the foundation types of established offshore wind farms in the world. With the further development of offshore wind power, the water depth of offshore wind farms will increase from 30m to 60m, and in order to meet the needs of large-capacity units for the bearing capaci...
