PROBLEM TO BE SOLVED: To provide a construction method for filling a core hole of a concrete structure with a filler, which enables simple and rapid preparation of the inorganic filler.SOLUTION: A cartridge houses a cylinder 1 which has a nozzle 11 at one end, a piston wall 2 movable toward a spout at the leading end of the nozzle 11 in the cylinder 1, and a mixed powder of a hydraulic composition and a thickener, which is stored as a mixture for the inorganic filler in the cylinder 1. In the construction method for filling the core hole of the concrete structure with the filler, a liquid is introduced into the cartridge from the spout; vibrations are applied to the cartridge; the mixture for the inorganic filler and the liquid are agitated and mixed together so that the inorganic filler 10 can be prepared in the cartridge; and the piston wall 2 is shifted to the spout side so as to infill the inorganic filler 10 into the wet or dry core hole from the spout. |
