FOUNDATION UNIT CONSTRUCTION METHOD FOR TRIPOD TYPE WIND POWER GENERATION PLANT ON THE SEA

摘要

PURPOSE: A method for constructing a tripod type foundation unit for an offshore wind power generation facility is provided to prefabricate the unit on the ground and then construct the unit on the seabed, thereby reducing the installation costs and improving workability. CONSTITUTION: A method for constructing a tripod type foundation unit for an offshore wind power generation facility includes a concrete body manufacturing step(S10) for manufacturing a concrete body having an insertion hole on the ground; a fixing pole installing step(S20) for embedding a fixing pole in the seabed; a suction step(S30) for sucking foreign matters inside the fixing pole in order to clean inside the fixing pole; a transporting step(S40) for transporting the manufactured concrete body to the sea; a sinking step(S50) for fixing the fixing pole into the insertion hole, and sinking the concrete body to the seabed; a placing step(S70) for placing the concrete at a position corresponding to the concrete body; a curing step(S80) for curing the concrete inside the fixing pole; and a cutting step(S90) for cutting the part of the fixing pole in which the concrete is not placed.
