PURPOSE:To perform repair in a short period at a low cost without reconstructing a building, constructing a new bridge, or temporarily supporting a bridge girder in the repairing method of a concrete bridge pier, the base of a large machine, or the other general concrete skeleton. CONSTITUTION:A repairing hole 9 is bored at the required repair position, multiple resin injection conduits 10, 11 are inserted into the inlet of the hole 9 while the rear end sections are protruded to the outside, the tip sections 10a, 11a of the resin injection conduits 10, 11 are located at the depth side of the hole 9, and the inlet 9a section of the hole 9 is sealed with grout 12. A repairing filler material is injected into the hole 9 with an injection device from one resin injection conduit 10. After the hole 9 is filled with the repairing filler material, the other resin injection conduit 11 used for an air vent is closed, the repairing filler material is further injected with high pressure into the hole 9 from the other resin injection conduit 10 to be infiltrated to fine sections of the position under repair. |
