Hollow columnar reinforcement method and hollow columnar reinforcement material used for this

摘要

To provide a reinforcement material for a hollow columnar object capable of achieving construction to be performed by a simpler method and a reinforcement method for the hollow columnar object using the reinforcement material.SOLUTION: A reinforcement material for a hollow columnar object includes: a reinforcement sheet 2 made of a fiber material, and formed in a cylindrical shape; a hollow pipe 4 provided on the inside of the vertical uppermost part of the reinforcement sheet 2, and formed with a plurality of through-holes 10 along an axial direction; and a balloon 6 provided on the inside of the reinforcement sheet 2 for fixing the vertical upper part of the reinforcement sheet 2 to an inner surface of an electric pole 100 from the inside. A reinforcement material 1 is pushed up from below by the hollow pipe 4, and disposed in the electric pole 100, and a filler is supplied to the hollow pipe 4, and injected into the electric pole 100 by using the through-holes 10 in order from below.SELECTED DRAWING: Figure 1
