PROBLEM TO BE SOLVED: To provide a reinforcement material for a hollow columnar object, which enables construction to be performed by a simpler method, and a reinforcement method for the hollow columnar object using the same.SOLUTION: A reinforcement material for a hollow columnar object includes: a reinforcement sheet 2 that is made of a fiber material and formed in a cylindrical shape; a hollow pipe 4 that is provided inside the vertical uppermost part of the reinforcement sheet 2 and in which a plurality of through-holes 10 are formed along an axial direction; and a balloon 6 that is provided on the inside of the reinforcement sheet 2 and that is used to fix the vertical upper part of the reinforcement sheet 2 to an inner surface of an electric pole from the inside. The reinforcement material 1 is pushed up from below by the hollow pipe 4 and arranged within the electric pole. A filler is supplied to the hollow pipe 4, and injected into the electric pole by using the through-holes 10 in order from below. |
