Accordingly, when the lifting hydraulic cylinder 22f is operated, the sealed container 2 moves in an arc shape around the fixed rotating shaft 22g, and at the same time, the outlet 2d of the outlet of the tube lining material of the sealed container 2 is opened. You can get up and down. In addition, the pipe lining material which is a subject of the present invention is a bending table which is a bent portion of the tube lining material 9 for folding the tube lining material 9 at the bottom of the manhole 20 and changing the direction in the direction of the pipe line 21 9c) can be easily secured. Next, the reversal insertion step S4 of the tube lining material 9 which changes the inversion advancing direction of the tube lining material 9 in the pipe direction will be described in detail with reference to the second embodiment.

The sealed container 2e containing the tube lining material is loaded on the truck 22, transported to the lining construction site, and the bag 22b of the truck 22 is disposed near the entrance of the manhole 20 installed on the road. do.

Then, the front and rear hydraulic cylinders 22d adjacent to the load stage 22b of the truck 22 are operated to slide the entire sealed container 2 to the rear of the truck 22, and the entire reverse nozzle 15 of the truck 22 is moved. It is taken out from the article stage and aligned so that the center of the entrance of the manhole 20 and the center of the reversal nozzle 15 may be in a straight line.

Next, the end of the lining material 9 which extends from the inside of the sealed container 2 to the inside of the manhole 20 is passed through the driving roller 5 and the carrying in and out 2d, and then the carrying in and out of the sealed container 2 again. The tube lining material 9 is folded back and fixed with a band 15a or the like to the inverting nozzle 15 adjacent thereto.

After operating the lifting hydraulic cylinder 22f to raise the inversion nozzle 15 installation side of the sealed container 2 by the diameter of the tube lining material 9, the air pressure is acted in the sealed container 2 to drive the rollers 5 ), The pipe lining material 9 is inverted to the pipe passage.

Here, once the air in the airtight container (2) is drained, the lifting hydraulic cylinder (22f) is operated again to lower the inversion nozzle (15), and the inverting end of the pipe lining material (9) is bent L-shaped in the direction of the conduit (21). The air in the airtight container 2, and then pressurize the air with a compressor 16 or the like in the airtight container 2 and invert the pipe lining material 9 into the pipe line 21 to insert the pipe lining material 9 into the pipe line 21. Can be.

Second Embodiment The sealed container 2e is to fix the sealed container 2 to the load stage 22b of the truck 22, unlike at the time of the alignment step S2 of the sealed container 2 shown in FIG. It is not necessary for the cylindrical first front support 18, the second front support 18a.

However, in order to maintain the level of the sealed container 2 more, the reverse nozzle stand 6 is used on the ground. The reversal nozzle stand 6 is a suspension stand provided to fit with the cylindrical part provided in the center of the said reversal nozzle 15.

The reverse inserting step (S4) of the tube lining material is the same, and compressed air is supplied from the compressor 16 to the sealed space S in the sealed container 2, and the driving roller 5 inside the sealed container 2 is supplied. The tube lining material 9 is pushed from the manhole 20 to the conduit 21 while monitoring the situation in the closed space S with a TV monitor 8a installed inside the sealed container 2. Invert to widen.

When reversal of the tube lining material 9 is completed, the compressed air in the sealed space S is taken out, and the bolt nut 15b connecting the carry-out port 2d of the sealed container 2 and the reverse nozzle 15 is connected. After separating and separating the control roller 11 and the flat hot water hose 10 inside the sealed container 2, the truck 22 may be released from the site.

In addition, the bottom inversion nozzle (27) shown in FIG. 8 shall be performed according to the hardening process (S5) and the hot water circulation process (S6) of the tube lining material shown in FIGS. ) Can also be used.

First, the pipe lining material reversal method of the present invention does not require a high warehouse for securing the head pressure even if the thickness of the pipe lining material is thick, it is possible to reverse insert the pipe lining material into the pipeline.

By sending the tube lining material stored in the second folded state to the driving roller, the force to pull the tube lining material becomes unnecessary, and the tube lining material is reversed by a low fluid pressure action.

Third, by matching the lining material outlet of the airtight container with the manhole inlet, the pipe lining material sent to the drive rollers falls down to the bottom of the manhole and falls down just below, requiring no force to pull the pipe lining material out of the airtight container. Do not. Therefore, the tube lining material can be reversed by lower fluid pressure.

Fourth, the pipe lining material reversed from the ground toward the manhole bottom must be changed in the L-shape from the manhole bottom to the in-pipe direction. At that time, the direction can be easily changed by releasing the air pressure in the tube lining material, lowering the entire sealed container, and bending the tube lining material inverting end at the L-shape toward the pipe direction as much as the lower length.
