In the injection device, a block is formed on the outer periphery of the shield frame for excavating the ground to form the tunnel hole, and the block is retractable radially outward from the shield frame. A backfilling agent injection device is characterized in that a backfilling agent injection tube that can be freely extended into the gap between the segment and the segment is provided so as to be able to freely enter and exit.
