<p><P>PROBLEM TO BE SOLVED: To provide a method for reversal-inserting a pipe lining material into a conduit which can reversal-insert the material surely and smoothly into an existing conduit without stopping the reversal of the pipe lining material during the insertion. <P>SOLUTION: The pipe lining material 17 is pulled out from a storage container 1 and led to a reversal nozzle 10 through a conduit 40, and the reversal of the lining material by the reversal nozzle is started by applying the pressure of fluid into a closed container. The reversed lining material is reversal-inserted into the conduit through a bent pipe 45 arranged in the inlet of the existing conduit 31 with its direction changed from the vertical direction to the horizontal direction. In this constitution, since the bending advance direction of the lining material is changed gently and surely into the extension direction of the conduit, the lining material can surely be reversal-inverted into the conduit without being affected by the level difference etc., of an existing pipe. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
