Abstract

PURPOSE:To make it possible to apply an inner surface lining to a branch pipe using a tube and a body with the supply of gas continued, by introducing the body for sticking the tube to the branch pipe into the tube from a ground section by using a passing line. CONSTITUTION:A traction device 4 introduced from a ground section 2a of one branch pipe 2 is sent by a pressurized gas through a main pipe 1 to a ground section 3a of the other branch pipe 2 so that a passing line 5 is passed between the ground sections 2a, 3a of the branch pipes 2, 3 through the branch pipes and the main pipe. A tube 9 is introduced into the branch pipe 2, to which an inner lining is to be applied, from the ground section 2a through the passing line 5, a body 16 is introduced into the tube 9, and the tube 9 is stuck onto the branch pipe 2a, 3a by the pressing action of the body 16, so that the introduction of the tube 9 and the body 1 can be carried out smoothly and the branch pipes 2a, 3a can be favorably lined with the tube 9. Thus, branch pipes connected to a main pipe embedded or situated in a hidden place can be lined using the body and the tube.
