Claims

[Scope of utility model registration request]

A jig that closes one opening of the gap formed between the outer circumferential surface of a pipe installed through a through hole provided in a wall, floor, etc. and the inner wall of the through hole, and has a diameter approximately the same as the outer circumference of the pipe. a circular hole portion and an annular portion surrounding the hole portion, the annular portion is provided with a separating portion having a removable connecting member attached to one or more opposing surfaces cutting the annular portion; When the jig is attached to the piping adjacent to the through hole, there is an elastic member on the surface facing the wall, floor, etc. of the annular portion that surrounds the opening and comes into contact with the surface around the opening. A backfill jig characterized by being provided with a protrusion.
