<p>PURPOSE:To form a synthetic resin pipe on the internal surface of a branch pipe by a method wherein a lining material is reversed and inserted easily into the branch pipe, having a small diameter and many curved. CONSTITUTION:When a lining material 1 is reversed and inserted into a branch pipe 31, the rod type body 6 of a guide member 2, inserted into the lining material 1, is pushed forward automatically by the reverse of the lining material 1. The pushed rod type body 6 advances along the internal surface of the branch pipe 31 by the curved surface of the guide part 7 at the tip end of the rod type body 6. The rod type body 6 is provided with a rigidity and flexibility whereby the rod type body 6 is bent in accordance with the configuration of the branch pipe 31 when the guide part 7 at the tip end is advanced, The reversed section of the lining material 2 is advanced along the rod type body 6, curved in accordance with the configuration of the branch pipe 31.</p> |
