PURPOSE:To make application easy and to make strength of a synthetic resin pipe uniform by fixing a heat-resistant film hose connected on an apex of an inner lining material on an outlet for the inner lining material of a reverse pressure vessel. CONSTITUTION:An inner lining material 1 on an apex of which a heat-resistant film hose 3 is connected is put in a heating and insulating container 4 wherein the temp. is kept at a shape recoverying temp. or higher and a shape memorizing temp. or lower. An outlet 7 for the inner lining material of the heating and insulating container 4 is connected with an inserting hole 9 for the inner lining material of a reverse pressure vessel 8 having a cylindrical outlet 10 for the inner lining material on its apex. Then, a heat-resistant film hose 3 is pulled out from the inserting hole 9 for the inner lining material of the reverse pressure vessel 8. Then, the apex of the heat-resistant film hose 3 is reversed in such a way that the inner face of the hose comes to the outside and it is fixed on the outlet 10 for the inner lining material. The outlet 10 for the inner lining material 10 is placed close to a pipe hole of an existing pipe 14. Then, an advancing heated fluid 17 with a temp. of the shape recovery temp. of the resin pipe or lower is continuously fed in the reverse pressure vessel 8 to reverse and advance the inner lining material 1 in the existing pipe 14. |
