とする埋め戻し治具。An annular jig that closes one opening of a gap formed between the outer peripheral surface of a pipe installed through a through hole provided in a wall, floor, etc. and the inner wall of the through hole, the inner peripheral surface being the outer peripheral surface of the pipe. It has a shape that comes into contact with the annular part, and a spaced part that can be connected and separated is provided at one place on the annular part, and a short and short elastic part that can be expanded and contracted is interposed at a position symmetrical to the spaced part with respect to the center point of the annular part. A backfilling jig characterized in that the remaining part consists of two circular arc-shaped rigid parts that are connected to each other.
