The present invention relates to a steel pipe for filling comprising a steel pipe column in which concrete is poured; a concrete inlet part which has an outlet disposed inside the steel pipe column and an inlet disposed outside the steel pipe column to put concrete into the steel pipe column; a cover part disposed at the outlet to prevent the entered concrete from reentering the concrete inlet part; and a connection member mounted to prevent the cover part from being separated from the outlet while concrete flows into the steel pipe through the concrete inlet part. The steel pipe for filling according to an embodiment of the present invention makes a concrete blocking work easy by blocking concrete doubly because concrete blocking is carried out by a blocking device attached to the outside of the steel pipe and by the concrete outlet part in the steel pipe. |
