Zusammenfassung:PROBLEM TO BE SOLVED: To provide a manhole repair method for constituting a solid lining layer for repair by a manhole repair material and a grout material inexpensively. SOLUTION: In this manhole repair method, a glass fiber reinforced vinyl ester resin 57 is laminated on a mold 55 having a columnar outer face by a hand lay up method, and a plate piece 49 is pressed against ribs 39, 41 for forming clearance and is sticked to them while the vinyl ester resin is not hardened. The plate piece 49 is made of the glass fiber reinforced vinyl ester resin being the same material as that of the manhole repair material 1. After the vinyl ester resin is hardened, diecutting is performed to constitute the manhole repair material 1 made of FRP and having an anchor structure integrally. COPYRIGHT: (C)2010,JPO&INPIT
