Assembly type high-pile bearing platform for offshore wind power

Abstract

The invention discloses an assembly type high-pile bearing platform for offshore wind power. The assembly type high-pile bearing platform comprises a plurality of steel pipe piles embedded into bed rock, a lower bearing platform erected at the upper ends of the steel pipe piles, a plurality of pieces of lower-layer profile steel used for connecting every two adjacent steel pipe piles, a plurality of pieces of upper-layer profile steel correspondingly arranged at the tops of the steel pipe piles, an upper bearing platform formed by pouring concrete materials on the lower bearing platform and hardening the concrete materials, and a bolt assembly; pile holes corresponding to the steel pipe piles in a one-to-one manner are formed in the bottom of the lower bearing platform; the bottoms of the lower bearing platform are supported through the lower-layer profile steel; each piece of upper-layer profile steel is arranged in the radial direction of the corresponding steel pipe pile; the bolt assembly comprises a plurality of bolts in the axial direction; and the bolt assembly and the lower bearing platform are poured together. According to the assembly type high-pile bearing platform, the construction efficiency of the high-pile bearing platform structure can be improved, the window period time needed by construction is shortened, the influences of the offshore environment conditions on construction of the high-pile bearing platform are reduced, and the construction quality of the high-pile bearing platform can be better controlled.

Description

technical field [0001] The invention relates to the field of offshore wind power equipment, in particular to an assembled high pile cap used for offshore wind power. Background technique [0002] With the advancement of the national carbon neutrality goal, the development and utilization of renewable energy such as wind power has important strategic significance for the optimization of China's energy structure. In the construction process of offshore wind power projects, the foundation structure of high pile caps has been widely used as the foundation type of offshore wind power projects independently developed by China. The technology is mature and suitable for soft ground. The high pile cap structure currently used mainly includes steel pipe pile sinking and concrete cap construction. The construction of the concrete cap requires the fabrication and installation of steel casings at the wind turbine installation site, pouring concrete, and finally dismantling the steel cas...
