A case has been described in which the hardening material 27 is injected into the bag body 17 in which 5, 39, and 43 are set so that the retaining wall 31 and the slope 29 are in close contact with each other. Even when the gap between the ground and the ground is filled with the hardening material, it is possible to use the bag body 17 in which the injection fittings 15, 35, 39, and 43 of each embodiment are set.

入作業能率が著しく向上することとなった。As described above, by using the bag filling device according to each claim, for example, a bag filled with a hardening material can be filled in a gap between a structure and the ground. The injection pipe used when the structure and the ground are brought into close contact with each other becomes unnecessary, and as a result, the efficiency of the operation of injecting the hardening material into the bag body is significantly improved as compared with the related art.
