When large diameter steel pipe files for offshore wind power generation are transported horizontally from the sea to the excavation position of foundation grounds (ground surface), buoyancy and self weight of buoyancy and self weight of buoyancy pipes of large diameter pipes are adjusted by using pump, A large-diameter steel pipe file can be buried with a barge with a simple crane installed without using equipment, and the large-diameter steel pipe file can be easily erected at the excavation position while preventing the rapid inflow of water by the inlet formed at the lower end of the large- In addition, by using a pump-integrated plug in which a pump is fastened on a plug for closing an upper end portion of a large diameter pipe tube pile, it is possible to separate and recover the large diameter pipe tube pile after the purchase of the large diameter pipe tube pile. By using an inlet cap to seal and transport, An embankment large-diameter steel pipe file for offshore wind power generation and a method of embedding the steel pipe file are provided.
