PROBLEM TO BE SOLVED: To provide a method of filling a grout material to a steel bar joint capable of reducing the volume of wastes. SOLUTION: Cartridges 31, 32 respectively containing a principal material and a hardener of the grout material are inserted to supply pipes 21, 22 from their end portions. The supply pipes 21, 22 are respectively fitted in a freely detachable manner to a large-diameter fitting portion 42 and a small-diameter fitting portion 43 of a mixing joint 41. The mixing joint 41, the supply pipes 21, 22 and the cartridges 31, 32 are installed to a mounting portion 19 of a grout filling device. Cylindrical portions 31a, 32a made of a flexible, thin film of the cartridges 31, 32 are crushed by pushing bottoms 31d, 32d of the cartridges 31, 32 to end sides of the supply pipes 21, 22 by using pistons 24, 25 thereby pushing out the principle material and the hardener of the grout material from the inside of the cartridges to a mixer 50 through the mixing joint 41. Then, the principle material and the hardener are mixed together in the mixer 50 and the mixture is filled from the mixer 50 to the inside of respective steel bar joints. COPYRIGHT: (C)2006,JPO&NCIPI
