PURPOSE:To simplify lining operation, by a method wherein after a lining tube has been inserted into a tube, a spreading member of the lining tube is inserted to spread it further. CONSTITUTION:A lining tube 21 is sent into a tube 36 while applying an //adhesive agent to an external circumferential surface of the lining tube 21 by an application device 40 for the adhesive agent. Then a spreading member 23 is inserted into the lining tube 21 under a state where the diameter of the spreading member 25 is reduced by an operation body 24. Then an end part of the lining tube 21 is clogged, the inside of the lining tube 21 is made to have negative pressure and the diameter of the spreading member 23 is reduced further by the lining tube 21. The operation body 24 is pulled out under this state. As closure of the end part of the lining tube 21 is released after pulling-out of the operation body 24, the lining tube 21 is spread by widening outward in a radius direction of the spreading member 23 through bouncing force. The lining tube 21 is pressed sufficiently against an inner circumferential surface of the tube 36 and the same does not hang down. |
