Abstract

PURPOSE:To make it possible to repair a crack without making a hole in the cracked part of a concrete structure with a drill or the like by installing an elastic sheet with a filler hole fitted with a check valve and a sheet supporter supporting and locking the circumference of this elastic sheet. CONSTITUTION:A repairing injector 10 is stuck together with a teeming hole 30 formed in a base 24 along a crack S of a structure C. When a repairing material P is pressed in by an injection valve or the like from a filler hole 20 of a filling pipe 18, an elastic sheet 12 consisting of a filmlike rubber member or the like is expanded, and the injection member P is filled up in the elastic sheet 12 and the base 24 or a constructing surface and the elastic sheet 12 as being charged in the cracks. When the elastic sheet 12 is expanded hereat, a projection 16 for forming a check valve 22 is solidly formed in the elastic sheet 12 via a clearance 16a, whereby only the sheet 12 comes to a state of being tensed, thus this projection 16 juts out to the inside of this elastic sheet 12. When the injection valve is removed in this state intact, the injection member P is charged by dint of shrinkage force of the elastic sheet 12 via the teeming hole 30.
