Abstract

PURPOSE: To use normal forms and a repair material at a low cost, and to remove the voids of a boundary surface between a base-body concrete structure and mortar or the like by constituting the concrete structure so that mortar or the like is placed on the boundary surface and adhesives can be injected. CONSTITUTION: Nozzles 1 for injection are arranged along a boundary surface B formed by removing a concrete layer in the underside section of the concrete structure C up to specified depth, and the other ends of hoses 4 as pipe bodies for injection, in which one ends are connected to the nozzles 1, are led out and disposed up to the outside of the structure C. Forms are arranged, dense concrete or mortar 12 is placed into the forms, mortar 12 or the like is cured, adhesives 13 are injected through the hoses 4 and the nozzles 1, and voids along the boundary surface B are filled with adhesives 13. Accordingly, voids are removed surely while adhesion onto the boundary surface B can be improved.
