  Next, operation | movement of the lining material continuous feeding apparatus 11 which concerns on this embodiment is demonstrated with reference to drawings. In FIG. 4, the lining material 25 provided outside is introduced from the lining material introducing portion 21 into the main body portion 12. At this time, lip portions 22a and 22b having elasticity are provided around the opening of the lining material introduction portion 21 so as to be folded inside, and the lining material 25 is introduced so as to slide on the lip portions 22a and 22b.

In the above, the lining material 25 is sent to the existing laying pipe and the existing laying pipe is repaired. However, in this embodiment, the resin tube (lining material 25) is inverted as the resin tube continuous feeding device to have a predetermined length. The inner layer 26a impregnated with the uncured curable resin that is sent out in the lateral direction and impregnated outward is cured, and both ends are closed with a closure or the like to form a cylindrical sealed container of a predetermined length It is. Since the inside of the sealed container is made of a plastic film which is the outer layer 26b of the resin tube (lining material 25), the sealing performance is ensured. Since the resin tube continuous feeding device has the same structure as the lining material continuous feeding device 11, the conveyance speed can be adjusted by the conveyance mechanism 37, so that a cylindrical sealed container 71 having a desired length is formed. I can do it.

  The sealed container 71 can be used, for example, as an emergency water supply tank. As shown in FIGS. 6A to 6C, the sealed container 71 having a predetermined length is placed on the bases 75a, 75b, and 75c. In the upper part of the sealed container 71, a water supply port 72 for supplying drinking water to the inside of the sealed container 71 and a pressurized air port 73 for introducing air into the inside are provided. A VP pipe 76 for taking out the drinking water in the container is attached to the lower part of the side surface of the sealed container 71 along the longitudinal direction of the sealed container 71.

  Thus, in the event of an emergency such as an earthquake, a sealed container having a length as required can be quickly formed, and a plurality of faucets 77a to 77f are provided. Since water supply can be received, rapid water supply is possible with a simpler device than water supply by a conventional water supply vehicle.

  As mentioned above, although some embodiment of this invention and the modification of each part were described, this embodiment and the modification of each part are shown as an example, and are not intending limiting the range of invention. . These novel embodiments described above can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
