PURPOSE: A method for repairing a manhole is provided to stably maintain the manhole without deformation because spacers of lining materials are integrally hardened with an inner wall of the manhole by fillers. CONSTITUTION: A method for repairing a manhole is as follows. Manhole lining materials impregnated with thermosetting resins are manufactured and comprise a shape corresponding to an inner wall of the manhole(1). The manhole lining materials are inserted into the inside of the manhole. The manhole lining materials are closely attached to the inner wall, and hardened. Curable fillers(60) are charged in a space between the manhole lining materials and the inner wall of the manhole and hardened. |
