A container body including an expansion tube having a bellows-like wall surface is provided to be filled with an injection filler, the container body communicating with a base having an injection port for pressing the injection filler into a crack portion in a wall surface of concrete or the like via a bellows cap communicating with the body, and upon pressing the injection filler into the crack portion by an extrusion part from the injection port of the base, while the container body maintains a state where the injection filler is injected into the crack portion under pressure from an elastic body of the extrusion part, the injection filler remaining in the container body is manually pressed toward the injection port during a period of time when a state where the remaining injection filler is pressed in is maintained, and then the container body is removed from the base and replaced with a new container body to mount the new container body. |

1. A method for injecting an injection filler into a crack, rock pocket, and a void portion around a steel bar in a concrete structure, the method comprising:
providing a container body (10), including an expansion tube having a bellows-like wall surface (10a), to be filled with an injection filler (X); providing the container body (10) communicating with a base (20) having an injection port (21) for pressing the injection filler (X) into a crack portion (B) in a wall surface, a floor surface, or the like being a concrete surface (A), via a bellows cap (40) having a slit (42a) and communicating with the container body; and upon pressing the injection filler (X) filled in the container body (10) by an extrusion part (50) into the crack portion (B) and a void portion in a floor surface, ceiling surface, or wall surface being the concrete surface (A) from the injection port (21) of the base (20), while maintaining a state where the injection filler (X) is injected into the crack portion (B) under pressure from an elastic body (51), such as a coil spring, of the extrusion part (50), in a state where a reserve capacity space where the injection filler (X) remaining in the container body (10) is allowed to be manually pressed toward the injection port (21) within a time during which a state where the remaining injection filler (X) is pressed in is maintained, and is pressurized to not change the filling flow velocity, removing the container body (10) from the base (20) to replace the container body (10) with and mount a new container body (10′) filled with a new injection filler (X). |
