Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a repair method which enables a through-hole to be surely and rapidly repaired only by work from the one side of a wall of a structure, when the through-hole penetrating the one side of the wall and the other side thereof is repaired. SOLUTION: In this method for repairing the structure, an expandably/contractibly constituted cover member 10 is inserted in a contracted state into the through-hole 4 from a one-side opening 6 of the through-hole 4 formed in the wall 1; the cover member 10 in the contracted state is expanded on the other side of the wall 1; the state of making the other side of the wall 1 and the through-hole 4 communicate with each other is cut off by making the cover member 10 in an expanded state abut on the peripheral wall surface of the other-side opening 5 of the through-hole 4; and subsequently, a filler 20 is infilled into the through-hole 4 from the one-side opening 6 of the through-hole 4.
