Claims

[Scope of Claim for Utility Model Registration] (1) A jig that closes one opening of the 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. An air pressure inlet that can be opened and closed is provided on the side, and by pressurizing air, it becomes a long rod-shaped body that tightly surrounds the outer circumferential surface of the piping. A connecting member that connects freely is attached,
A backfilling jig characterized in that it is constituted by a flexible hollow body that forms an annular body inscribed in the outer circumferential surface of the piping by winding it around the outer circumferential surface of the piping and connecting the connecting member to the outer circumferential surface of the piping. . (2) A jig for backfilling according to claim 1, which is provided with a large number of elastic protrusions on a portion corresponding to the inner circumferential surface of an annular body inscribed in the outer circumferential surface of the pipe.
