METHOD FOR CONTRUCTING MARINE WIND POWER SUPPORTING STRUCTURE WITH SUCTION FILE AT SEA

摘要

PURPOSE: A method for constructing a marine wind power supporting structure with a suction pile at sea is provided to reduce construction period by manufacturing an integral foundation with a suction pile on land, penetrating the foundation into seafloor through self-load and suction pressure, and fixing the foundation by inserting ripraps into the foundation. CONSTITUTION: A method for constructing a marine wind power supporting structure with a suction pile at sea comprises the following steps: a step of installing a manufacturing space in land; a step of manufacturing a plurality of suction pumps in the manufacturing space; a step of refloating a guide frame by using a marine crane, penetrating a foundation, connecting the guide frame with the refloating unit, refloating the guide frame, and inserting the bucket of the foundation to a predetermined depth in the water to transfer to an installation site; a step of descending the guide frame to penetrate the foundation into the seafloor by self-load; a step of operating the suction pump to penetrate the bucket into the seafloor through suction pressure; and a step of loading ripraps(S) to the upper side of a slab by using an angle crane(50) in which a cram shell(51) is installed.
