PROBLEM TO BE SOLVED: To facilitate padding even in a small place by injecting a liquid mortar to a hopper by a pipe with a hopper, running liquid mortar by a fixed pipe and connecting a pipe with a socket if the length is not enough. SOLUTION: A pipe 1 with a hopper is inserted into a fixed pipe 2 of a liquid mortar injector, a liquid mortar is injected from the hopper, and when running horizontally the liquid mortar, the liquid mortar flows out from a pipe 3 with a socket. When running the liquid mortar vertically, only the pipe 1 with a hopper is used, and if the length is not enough, by connecting the pipe 3 with a socket, the liquid mortar can be injected vertically and horizontally. Therefore, when backfilling a floor opening in a shaft, vertical injection is used and horizontal injection is used for fixing voids of bath legs, a liquid mortar can be injected into even small places.
