Subsequently, when the compressed air G is supplied into the reinforcing tube 20, the reinforcing tube 20 is inflated and adhered to the inner surface of the conduit 10 (S120).

The steam generating unit 220 generates high temperature steam S and supplies the steam to the reinforcing tube 20 through the steam supply pipe 230. When the high temperature steam S is supplied into the reinforcing tube, the reinforcing tube 20 is thermally cured to the pipe 10 to be bonded (S130). When the steam S is moved along the reinforcing tube 20, low-temperature condensed water W1 is generated in contact with the low-temperature air inside the reinforcing tube 20. The low temperature condensate W1 is moved to the downstream side along the reinforcing tube 20.

The low temperature condensed water W1 generated inside the reinforcing tube 20 and the waste steam S1 thermally cured by the reinforcing tube 20 are moved to the heat exchange bath 330 at step S140. When the condensate return pipe 310 and the steam recovery pipe 320 are inserted into the other end 23 of the reinforcing tube 20 and the condensate recovery pump 313 is driven, Is recovered to the heat exchange tank (330). Also, the waste steam S1 is recovered to the heat exchange tank 330 through the steam recovery pipe 320.

The waste steam S1 is exchanged with the low temperature condensate W1 in the heat exchange tank 330 and the high temperature condensed water W2 heated by the heat exchange is supplied to the reinforcement tube 20 again at S150. The high temperature condensate W2 is supplied to the inside of the reinforcing tube 20 through the inversion casing 123 through the condensate supply pipe 340 connected to the heat exchange tank 330.

As shown in FIG. 4, the low-temperature condensate W1 remains in the interior of the reinforcing tube 20. In this state, when the high-temperature condensate W2 is supplied by the condensate supply pump 341, the remaining low-temperature condensate W1 is moved to the downstream side by the water pressure or the heat is exchanged with the high-temperature condensate W2, I will go up.

The high temperature condensed water W2 moves along the reinforcing tube 20 to move the remaining low temperature condensate W1 and thermally cure the unhardened area of the reinforcing tube 20 that is floating in the conduit 10 at step S160. . The high temperature condensed water W2 comes into contact with the reinforcing tube 20 and becomes uncured as shown in Figure 1 so that the area a floating on the surface of the conduit 10 is thermally cured by the heat of the high temperature condensed water W2 do. 4, the low-temperature condensate W1, which has been accumulated in the region 11 depressed by the pipeline 10 or the region where the pipeline 10 is curved due to the gradient defect, is returned again to the high-temperature condensate W2 And is thermally cured by the heat of the high-temperature condensate water (W2).

The low temperature condensed water W1 which has been moved downstream by the moving pressure of the high temperature condensed water W2 is again collected by the condensed water returning pipe 310 into the heat exchange tank 330 and heated by the heat exchange with the waste steam S1 And then to the inside of the reinforcing tube (20). Due to the circulation structure of the condensed water, the entire region of the reinforcing tube 20 can be thermally cured to the conduit 10 without any uncured region.

On the other hand, in the above-described sewer unguarded full repair system 1, the work of reinforcing the pipeline 10 by inserting the reinforcing tube 20 into the manhole 30a at the downstream side from the upstream side manhole 30 proceeds. However, there is a possibility that it is difficult to proceed with the operation of inserting the reinforcing tube 20 because the structure is installed in the upstream manhole 30 and the vehicle is difficult to enter or the flow population is large.

In this case, as shown in FIG. 6, the reinforcing tube 20 is inserted into the upstream manhole 30 from the downstream manhole 30a to reinforce the conduit 10. When the reinforcing tube 20 is inserted from the downstream manhole 30a into the upstream manhole 30, the low temperature condensed water W1 is collected on the downstream manhole 30a side. The low temperature condensate W1 flows into the condensate storage tank 331 through the condensate return pipe 310a.

At this time, the waste steam S1 is discharged to the atmosphere through the waste steam discharge pipe 320a.

The steam of the steam generating unit 220 is transferred to the steam storage tank 333 for heat exchange of the low temperature condensate W1. The high temperature steam S generated in the steam generating unit 220 is supplied to the reinforcing tube 20 through the steam supply pipe 230 and a part of the steam S is supplied to the steam storage tank 333).

In the heat exchange tank 330, the condensed water W1 is heated by heat exchange with the hot steam S, and is re-supplied to the reinforcing tube 20 through the condensed water supply pipe 340.

Then, the quality of the maintenance work of the pipeline 10 can be improved by thermally curing the uncured reinforcing tube 20 by raising the temperature by heat exchange with the hot steam while circulating the low-temperature condensate W1 in the same manner as above .

As described above, according to the present invention, the low-temperature condensed water generated in the inside of the reinforcing tube is heated by heat exchange with the waste steam, And the unhardened area of the reinforcing tube is thermally cured. Accordingly, the reinforcing tube can be uniformly attached to the entire area of the entire channel without the uncured area, thereby completing the maintenance work on the channel.

In addition, the reinforcing tube can be thermally cured by the high-temperature condensed water even in a poor-gradient region or a recessed region of the piping, which has been hardly thermally cured in the past, so that the quality of piping repair can be improved.

In addition, since the existing waste heat of the steam is utilized, the recycling of resources is effected, and the amount of discarded steam is also reduced.
