The invention discloses a connection structure of an offshore wind power composite cylindrical foundation and a tower cylinder, and a construction method. According to the scheme, a fan bottom sectiontower cylinder is hoisted in a harbor pool, so that the height of a suspended structure object on the land is reduced; the applicable water depth range of the composite cylindrical foundation is expanded; the weight of the suspended structure object when the suspended structure object is hoisted into the harbor pool is reduced, so that the construction difficulty is reduced. The connection structure comprises a steel pad plate, a bottom section tower cylinder bottom flange, high-strength bolts and an anchor pad plate, wherein the bottom section tower cylinder bottom flange is arranged at thebottom of the bottom section tower cylinder; the steel pad plate is arranged under the bottom section tower cylinder bottom flange; the anchor pad plate is arranged at the top of a prestressed arc-shaped reinforced concrete structure; and the high-strength bolts are connected with the bottom section tower cylinder bottom flange, the steel pad plate and the anchor pad plate.
Description
technical field [0001] The invention relates to a connection structure and a construction method of an offshore wind power composite tubular foundation and a tower, and belongs to the technical field of marine engineering. Background technique [0002] The composite cylindrical foundation of offshore wind power is an offshore wind turbine foundation structure in which the cylinder is inserted into the seabed through the internal and external pressure difference formed by pumping out the water and air in the cylinder. It is composed of a prestressed arc-shaped reinforced concrete structure and a wide and shallow steel cylinder. Significant, shallow soil characteristics. [0003] The lower steel cylinder of the composite cylindrical foundation is inserted into the seabed soil to provide bearing capacity; the upper part of the prestressed arc-shaped reinforced concrete structure is partially immersed in water to withstand long-term marine environmental effects such as ocean cur...
