A method is used in which the m-swivel tube 13 moves forward while rotating above it. Further, as shown in FIG. 4, in the construction work to rehabilitate the existing pipe 14 by inserting the helical pipe 13 into the aged existing pipe 14 while using the pipe making machine 132, the spiral pipe 13 A method is employed in which the spiral tube 13 is guided by pulling the wire 411 at the end of the tube.

１１１が設けられている。After the belt-shaped body 131 is supplied from the ground to the pipe making machine 132 to start manufacturing the helical tube 13, the support jig 11t is pressed and supported on the inner circumferential surface of the end of the helical tube 13. At this time, it is necessary to align the center of the through hole 112, that is, the center of the guide wire 12 with the tube axis of the spiral tube 13. As an example of the support jig 11 is shown in FIG. 2, nine through holes 112 are formed in the center, and support arms 111 are provided radially at equal intervals in three directions.
通孔１１２の内周にボールベアリング１１４が設けられ
ていると、前記支持腕１１１がガイド用線材１２に沿っ
てより一層円滑に回転・前進することができる。If a ball bearing 114 is provided on the inner periphery of the through hole 112, the support arm 111 can rotate and move forward along the guide wire 12 even more smoothly.
支持腕１１１には管内周面を直接押圧するアーム１１５

こともできる。When the support jig 11 is pressed and supported on the inner circumferential surface of the end of the helical tube 13 immediately after tube manufacture in this way, the helical tube 13 advances along the guide wire 12 due to the driving force generated by the manufacture. In this way, the m-circle tube 13 is smoothly inserted into the old existing tube 14 without coming into contact with the inner circumferential surface of the tube 14 at all. The guide wire 12 may be made of steel, and if the old existing pipe is a curved pipe with a large radius of curvature, it can be made by fixing a steel material with the same radius of curvature so as to match the axis of the curved pipe. A spiral tube can not only move straight but also curve within its own variable range of internal pressure.

である。As described above, the method of the present invention is particularly effective when using spiral pipes to rehabilitate old existing pipes where scale, sludge, etc. have adhered to the inner peripheral surface and it is difficult to insert new pipes due to contact friction. However, this method is also effective at factory manufacturing sites.
