Summary:To provide a tile removal method that can remove a large number of porcelain tiles attached to an inner wall of a tunnel in a short time with a small amount of labor and repaint an inner wall surface of a concrete skeleton, and a heating device for repair used in the tile removal method.SOLUTION: Provided is a method of repairing a tunnel where a large number of porcelain tiles 4 are attached to an inner wall surface of a concrete skeleton 2 along a road 1 through mortar for bonding tiles, and the porcelain tiles are removed from the concrete skeleton along the road so as to repaint the inner wall surface of the concrete skeleton from which the porcelain tiles are removed. A tiled wall surface to which the porcelain tiles are attached is heated from the surface side to raise a temperature of the mortar for bonding tiles before removing the porcelain tiles from the concrete skeleton, then the porcelain tiles are mechanically peeled off from the concrete skeleton so as to repaint the inner wall surface of the concrete skeleton from which the porcelain tiles are removed.SELECTED DRAWING: Figure 1 【課題】少ない労力でトンネル内側壁面に貼られた多数枚の磁器タイルを短時間で撤去して、再びコンクリート躯体の内側壁面を内装できるタイル撤去方法及びタイル撤去方法で使用する補修用加熱装置を提供する。【解決手段】道路1に沿ったコンクリート躯体2の内側壁面に、タイル接着用モルタルを介して多数枚の磁器タイル4を貼ってあり、道路に沿って多数枚の磁器タイルをコンクリート躯体から取り外して、それらの磁器タイルを撤去したコンクリート躯体の内側壁面を、再び内装できる様にするトンネルの補修方法であって、コンクリート躯体から磁器タイルを取り外す前に、多数枚の磁器タイルを貼ってあるタイル貼り壁面を、その表面側から加熱してタイル接着用モルタルを昇温させた後に、多数枚の磁器タイルをコンクリート躯体から機械的に剥離し、磁器タイルを撤去したコンクリート躯体の内側壁面を、再び内装できる様にする。【選択図】図1
