Construction device and method for offshore wind turbine foundation with piling performed later

ZHU RONGHUA

The invention provides a construction device and method for an offshore wind turbine foundation with piling performed later, and belongs to the technical field of offshore wind turbine foundation construction. The construction device comprises the offshore fan foundation, a pipe casing and a sleeve. The pipe casing is used for installation of a steel pile and arranged at the bottom of the offshore wind turbine foundation. The lower end of the sleeve is detachably connected with the upper end of the pipe casing. According to the construction device and method for the offshore wind turbine foundation with piling performed later, by adding the sleeve for temporary construction, it is ensured that offshore wind turbine foundation leveling and grouting connection work does not need underwater operation performed by workers and completely adopts dry operation, and operation is safe and reliable; traditional wet grouting is changed into dry grouting, constructors achieve real-time monitoring on a pipe casing platform, and construction precision is easy to control; and meanwhile, offshore rock-socketed construction is convenient.
