Abstract

Provided is a restoration pipe pulling-in method which can easily determine whether pilling-in of a restoration pipe is possible wherein the restoration pipe has a diameter as much as large relative to a deteriorated drainage channel, and which can pulling a restoration pipe into a sewer pipe wherein the gap between the restoration pipe and the sewer pipe is shorter. The restoration pipe pulling-in method comprises preparing a dummy restoration pipe 30′ which imitates the restoration pipe; attaching a determination jig 10 for determining whether pulling-in of the restoration pipe is possible to an insertion-side leading end portion of the dummy restoration pipe 30′; pulling the dummy restoration pipe 30′ with the determination jig 10 into the existing pipe 1; after confirming completion of passing-through of the dummy restoration pipe 30′ with the determination jig 10, attaching a pull-in jig to a leading end portion of the restoration pipe; and arranging the restoration pipe over an entire length of the existing pipe 1, by inserting the restoration pipe with the pull-in jig, through an upper opening 2b of the existing pipe 1, into the existing pipe 1, and by pulling the pull-in jig with a wire.
