<p><P>PROBLEM TO BE SOLVED: To provide a tool for pulling a regeneration pipe in capable of avoiding dropping of the regeneration pipe from a tip and catching of the regeneration pipe in a bent section of an existing pipe when pulling the regeneration pipe into the existing pipe. <P>SOLUTION: A substantially cylindrical insertion part 2A inserted into the inside of the regeneration pipe 1 is provided in a tip plug 2 mounted in a tip part of the regeneration pipe 1 made of thermoplastic resin, and channels 23, 23 are provided in a plurality of sections on an outer peripheral face of the insertion part 2A to deform the regeneration pipe 1 to fit it into the channels 23, 23 by utilizing tightening bands B, B. Consequently, it is possible to prevent the tip plug 2 from dropping from a tip of the regeneration pipe 1 during regeneration pipe pulling-in work. Also, it is possible to prevent the tip part of the regeneration pipe 1 from being bent to prevent a situation where the regeneration pipe 1 is caught in the existing pipe and cannot be pulled in. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
