の空気が洩れないようにしておく必要がある。 In order to line the outside of the synthetic resin pipe 16 with concrete mortar using the above-mentioned implementation device, the valve 12 is switched to first reduce the pressure in the arm 13 attached to the rotating shaft 2, and the support rod 14 is moved in the direction of the arrow 38. (the support plate is in the position shown by the chain line in FIG. 2), and then the synthetic resin pipe 16 is fitted. In the actual manufacturing process, after opening the bearings provided at the top of the frames 1 and 1a and lifting the rotating shaft 2, a synthetic resin pipe is fitted from one side. Alternatively, the rotating shaft 2 can be connected to the rotating shaft of the pulley 3 at the pedestal 1a, the synthetic resin pipe to be processed has the rotating shaft attached in advance in the preparatory process, and the synthetic resin pipe with the rotating shaft is attached. Alternatively, it can also be removed. In such a case, an air supply housing is provided on the upper part of the pedestal 1, and the tip of the air supply pipe 11 is connected to this housing. In this way, the supply and exhaust system for the arm can be completed at the same time as the rotating shaft is installed. Once the synthetic resin pipe 16 has been fitted as described above, pressurized air is inserted as shown by the arrow 33 by switching the valve 12, and the pressurized air is sent into the arm 13 through the rotating shaft. The support rods 14 are pushed outward as shown by arrows 34, and the support plate 15 abuts against the inner wall of the synthetic resin pipe 16, thereby reliably integrating the rotating shaft and the synthetic resin pipe 16. In the above, a lath net 36 is fixed in advance to the outer wall of the synthetic resin pipe 16 via a spacer 35. Next, start motor 8 and shift gears 9, 7,
While slowly rotating the rotating shaft through the chain 10, reducer 4, pulleys 3 and 5, and belt 6, pressurized air is supplied to the housing 24 through the air pipe 28.
Blow inward. Thus roving cutter 25,
Glass fiber roping 26 as rotation of 25a
is cut, mixed into concrete mortar, and sprayed onto the outer wall of the synthetic resin pipe 16 from the nozzle 23. When the rotating shaft 2 is slowly rotated by the interlocking device (interlocking mechanism between the motor 8 and the rotating shaft 2) in the direction of the arrow 37 in FIG.
The lining process is completed by finishing the lining with a smooth surface and pressing the concrete mortar tightly. Next, the processed synthetic resin pipe together with the rotating shaft is removed from the mount, and the next processed synthetic resin pipe with rotating shaft is installed. In the method described above, in which the rotating shaft and the synthetic resin pipe are integrated in the preparation stage, when installing and removing the synthetic resin pipe with the rotating shaft, the air inlet section at the end of the rotating shaft is closed (for example, by installing a valve on the rotating shaft). It is necessary to prevent the air inside the arm from leaking during movement.

Further, the reinforcing member is not limited to the lath net, and may also be a known reinforcing bar cage or hoop bar wrapped around the reinforcing member. Moreover, metal, carbon, or synthetic resin fibers can also be used instead of glass resin.

効果がある。(Effects of the Invention) That is, according to the present invention, since concrete mortar is sprayed while rotating the pipe body surrounding the reinforcing member on the outside, concrete can be easily, reliably, and efficiently rolled around the outside of the pipe body. It has a beneficial effect. In addition, spray guns and finishing rolls are installed on the outside of the rotating shaft that supports the pipe body, so rotation of the rotating shaft, spraying with the spray gun, and surface finishing with the finishing roll are fully automated. It has the effect of being able to process the outside of the body continuously and with high efficiency.
