In the figure, J is an upright hole, and K is a winding drum arranged at the opening of the upright hole J. Further above the ground,
The electric power generator L, the electric heat welding transformer M, and the vehicle O on which the hydraulic motor unit N is mounted are waiting, and the electric wire and the hydraulic hose arranged from the electric heat welding transformer M and the hydraulic motor unit N Is connected to a required portion of the pipe making machine H. As a technical problem that occurs in such a lining construction work, whether the pipe-making machine can be carried into the narrow vertical hole J and whether the operation is easy, and the buried pipe Q is always located at the center position of the vertical hole J. Whether or not it is possible to easily adjust the eccentricity of the pipe making machine installed at the bottom of the upright hole, rather than being arranged, is a matter. As is clear from the above description, the pipe making machine H of the present embodiment can easily overcome the above problems. That is, according to the lining pipe manufacturing machine H of the present embodiment, the pillar member 11 and the upper and lower movable beams 13 and 14 supporting the pipe manufacturing mechanism parts are moved and adjusted, and the angle of each pipe manufacturing mechanism part is adjusted. By doing
It is possible to easily respond to changes in pipe diameter. Then, the continuously supplied strip-shaped member 1 is passed through each of the pipe making mechanism parts of the joining mechanism part 40, the guide mechanism parts 70 and 80, and the rotation mechanism part 50 and spirally wound to automatically manufacture the pipe. You can do it. At this time, a pulling force (pulling back force) is introduced into the belt-shaped member 1 by reducing the feeding speed of the belt-shaped member feeding mechanism portion 20, and the slack of the belt-shaped member 1 in the other pipe manufacturing mechanism portions is adjusted to be uniform. A lining pipe P having a diameter can be obtained.

That is, the following aspects are included in the technical scope of the present invention. The pipe manufacturing mechanism is not necessarily limited to the position of this embodiment, and the essential point is that it can be arranged at a position that guarantees the perfect circle of the manufactured pipe. For example, the joining mechanism portion 40 is appropriately positioned not only in the horizontal position passing through the central axis of the pipe P but also in the closing position of the belt-shaped member 1 to be supplied. Further, the feed mechanism unit 20 can be attached to the upper portion of the machine body frame 10 (that is, on the upper beam 12). Eliminating the lower movable beam 14 and mounting the lower guide roller mechanism 70 on the lower beam 15. In this case, the pipe diameter is adjusted by doubling the movement of the upper movable beam 13, and the joining mechanism 4
0 and the side guide mechanism 80 are also movable. The outer guide roller 71 of the lower guide mechanism unit 70 is abolished and guided by the inner guide roller 72. Dispose of the welding roller 43 in the joining mechanism section 40. Further, instead of the welding roller 43, the joining rollers 41, 42
A welding means (for example, an adhesive injection nozzle) is arranged at a position before the strip-shaped members 1 are overlapped with each other. The angle adjusting mechanisms 28, 47, 58, 75, 84 are not limited to those of this embodiment. What is essential is that each pipe-making element can be adjusted to a predetermined angle according to the pipe diameter. The constituent members of the machine body frame 10 are made of appropriate materials and shapes, the driving force is changed to an electric motor instead of a hydraulic motor, the drive transmission is changed to a chain, and appropriate means (for example, belt transmission) is used. Since it is a matter of course for design, it will not be described in detail.

EFFECTS OF THE INVENTION According to the pipe manufacturing machine of the present invention, it is possible to move and adjust each pipe manufacturing element in the vertical direction and the width direction (horizontal direction) according to the pipe diameter, and adjust the angle. A pipe having a pipe diameter can be produced, and therefore, it is suitable for lining construction in a sewer pipe. Further, since the inner and outer surfaces of the strip-shaped member are sandwiched by the inner-outer surface rollers and driven and fed, the strip-shaped member is surely folded into a tubular shape, and a lining pipe with high roundness can be obtained.
