A manhole lift up repairing method is provided to reduce the number of repair work apparently since the durability of road filler and basis filler are relatively good. A manhole lift up repairing method comprises following processes: a first process of cutting the road by using the road cutter; a second process of excavating and removing the road of the part which is cut with cutter; a third process of setting up the height controller in the bottom flange of the manhole cover supporting board(20); a fourth process of founding the height verifier stand in the road; a fifth process of controlling height in order to coincide the top end portion of the manhole cover supporting board with the surface of road; a sixth process of applying the basis filler rapid hardening mortar(M) in the space part which is excavated of the manhole cover supporting board surrounding and ossifying; a seventh process which applies the road filler resin concrete(normal temperature ascon)(C) to the same height as the surface of road on the top of the basis filler rapid hardening mortar and ossified. |
