Summary: | To remove a large number of porcelain tiles attached over long distances along a tunnel road with a short time with little effort, and to re-decorate an inner wall surface of a concrete skeleton.SOLUTION: In a method for repairing a tunnel for re-decorating an inner wall surface of a concrete skeleton 2 from which porcelain tiles 4 are removed in which the large number of porcelain tiles 4 are attached on the inner wall surface of the concrete frame 2 along a road 1 with a synthetic resin adhesive 3 and the large number of porcelain tiles 4 are removed from the concrete skeleton 2 along the road 1, the tiled wall surface on which the large number of porcelain tiles 4 are attached is heated from a surface side before removing the porcelain tiles 4 from the concrete skeleton 2, the large number of porcelain tiles 4 are mechanically peeled off from the concrete frame 2 after raising the temperature of the interface between the large number of porcelain tiles 4 and the synthetic resin adhesive, and the inner wall surface of the concrete skeleton 2 from which the porcelain tiles 4 have been removed can be re-decorated.SELECTED DRAWING: Figure 1
【課題】少ない労力でトンネルの道路に沿って長距離に亘って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ようにする。【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、合成樹脂接着剤3を介して多数枚の磁器タイル4を貼ってあり、道路1に沿って多数枚の磁器タイル4をコンクリート躯体2から取り外して、それらの磁器タイル4を撤去したコンクリート躯体2の内側壁面を、再び内装するトンネルの補修方法であって、コンクリート躯体2から前記磁器タイル4を取り外す前に、多数枚の磁器タイル4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多数枚の磁器タイル4と合成樹脂接着剤との界面を昇温させた後に、多数枚の磁器タイル4をコンクリート躯体2から機械的に剥離し、磁器タイル4を撤去したコンクリート躯体2の内側壁面を、再び内装できる様にする。【選択図】図1 |
