PROBLEM TO BE SOLVED: To provide a manhole repairing panel for easily repairing a manhole. SOLUTION: The manhole repairing panel 1 is installed on an inner peripheral surface of a body 11 of the manhole 4, to cover the inner peripheral surface of the body 11. A filler 5 is filled and hardened in clearance between the inner peripheral surface of the body 11 of the manhole 4 and an outer peripheral surface of a panel body 21 of the manhole repairing panel 1. A variation is not caused in the finish without requiring skill for work more than when repairing by banking concrete again on the inner peripheral surface of the manhole 4. Large-scale equipment is not required more than when repairing by lining the manhole 4. Repairing work of the manhole 4 can be performed easily and surely. COPYRIGHT: (C)2005,JPO&NCIPI
