PURPOSE:To inject a repairing material surely and economically, by injecting gas having pressure higher than atmospheric pressure in an airtight container and injecting the repairing material in a crack through an introducing pipe part by utilizing the high internal pressure of said container. CONSTITUTION:At first, the seat part 11 of an introducing pipe part 1 is fixed to the exposed crack 4 of a structure 3 to be repaired by an adhesive while compressed air is injected in a container 22 through a valve apparatus 21 to make the internal pressure of the container slightly higher than atmospheric pressure. Then, a predetermined amount of a repairing material is injected in the container 22 against the rising in the internal air pressure of the container 22. The container 22 having the repairing material injected therein by this method is threaded with and connected to the connection part 12 of the pipe part 1 through the valve apparatus and, when the valve body 213 of the valve apparatus 21 is pushed up by the connection part 12 to open the valve apparatus 21, the repairing material in the container 22 is made to flow out by the pressure of compressed air in the container to be made to surely flow into the crack 4 of the structure 3.
