To provide an injection apparatus for preventing an injected repairing material from flowing backward, even if an injection part is removed, immediately after injecting the repairing material, in the injection apparatus for injecting the repairing material into an injection hole bored in a concrete structure.
This injection apparatus is composed of a hollow body pipe 101 for arranging a flange part 144 in a tip part, and arranging a check valve 142 inside, a connecting nut pipe 102 of a hollow body, and a base end side hollow body 103 for arranging an injection port of the repairing material in a base end part of a hollow body. An elastic tube 151 is fitted to the body pipe 101, and the body pipe 101 projecting from the elastic tube is joined by a screw to the connecting nut pipe 102. The base end side hollow body 103 and the connecting nut pipe 102 are joined by a screw. When the body pipe 101 is intruded into the connecting nut pipe 102 by rotating the base end side hollow body 103, the elastic tube 151 is compressed in the shaft direction between the flange part of the body pipe 101 and the connecting nut pipe 102, and is diametrally expanded.
