Next, the tube 600 embedded in the loading box 200 is drawn out and transferred to the support 400 through the roller conveyor 300 (S200). At this time, the tube 600 in the frozen state in the stacking box 200 is drawn out, transferred to the second horizontal frame 402 of the support 400 while being transported with minimal friction through the roller conveyor 300, and then guided. It spans the roller 411 and then deflects downward. Here, the tube 600 inside the loading box 200 is withdrawn through the outlet 230 and seated on the roller conveyor 300 along the withdrawal roller 240. At this time, one end of the tube 600 is fastened to the rope 453 of the hoisting portion 450, and the tube 600 is loaded while the rope 453 is wound on the rotating body 452 rotated by the motor 451. It is to be transferred from the 200 to the support (400). Of course, the tube 600 may be drawn out by an operator.

Next, one end of the tube 600 drawn out to the support 400 is cut and then inverted, and one end of the inverted tube 600 is fixed (S300). Here, one end of the tube 600 is inverted by a predetermined length in the longitudinal direction by an operator, and the cutting length may vary according to the diameter of the tube 600 or the like. One end of the cut tube 600 is inverted, and one end of the inverted tube 600 is interposed between the second horizontal frame 402 and the moving panel 422 to be fixed. Here, the movable panel 422 is moved by the tube fixing cylinder 421 and is fixed in close contact with the second horizontal frame 402 to fix one end of the inverted tube 600 to the second horizontal frame 402. . At this time, one end of the inverted tube 600 is moved between the moving panel 422 and the second horizontal frame 402 by a rope 453. In addition, the rope 453 continuously provides a traction force for maintaining the fixed position of the end portion of the tube 600 even when one end of the tube 600 is fixed. This is to ensure that the inverted end of the tube 600 is maintained in a fixed position while the tube 600 is inserted into the conduit 500. As a result, the tube 600 is stably inserted into the conduit 500.

Next, water or air is injected into the tube 600 in an inverted state and expanded and drawn out so that the inversion speed of the tube 600 is adjusted (S400). In more detail, one end is fixed to the moving panel 422 and the second horizontal frame 402 so that the water is passed through the first injection device 441 and the second injection device 442 while the tube 600 is inverted. Alternatively, when air is injected, it is expanded while being drawn out. Here, the inversion of the tube 600 proceeds smoothly by the film layer of the embossed tube 600. In addition, the position in which water or air is injected into the tube 600 is the upper injection hole 501 between the first cylinder 431 and the second cylinder 432 for adjusting the reversal speed of the tube 600, and It is located in two places of the lower injection hole 502 below the two cylinders 432. Therefore, the first pressing member 433 positioned above the injection position and moved by the first cylinder 431 presses the tube 600 toward the third horizontal frame 403, thereby being injected into the tube 600. The phenomenon that water or air is discharged to the inverted end side is prevented. At this time, the pressing force of the first pressing member 433 pressurizing the tube 600 is adjusted to adjust the amount of water or air leaking toward the inverted end of the tube 600, whereby the inversion speed of the tube 600 is increased. Adjusted. In addition, the second pressing member 434, which is located below the injection position and moved by the second cylinder 432, presses the expanded tube 600 toward the fourth horizontal frame 404 so that water or air Injection amount is variable. Of course, the injection amount of water or air is controlled by adjusting the pressing force of the second pressing member 434 which presses the tube 600, thereby controlling the reversal speed of the tube 600. In addition, the amount of water or air injected from the first and second injection devices 441 and 442 may be adjusted to control the reversal speed of the tube 600. At this time, the injection amount of the first and second injection devices 441 and 442 is adjusted by the sensor measuring the reversal speed of the tube 600.

Next, the tube 600, which is expanded and pulled out of the inverted state, is inserted into the pipe line 500 and then attached to the inner surface of the pipe while being thermoset (S500). At this time, the tube 600 which is expanded and drawn out is guided toward the manhole 510 through the first guide panel 460 installed on the support 400, and enters the manhole 510 through the guide tube 520. do. At this time, the guide tube 520 is installed so that one end is located on the ground and the other end is located inside the manhole 510, the tube 600 passes through the guide tube 520. In addition, the tube 600 entering the manhole 510 through the guide tube 520 enters the pipeline 500 through the second guide panel 530 installed at the inlet of the pipeline 500. Here, it is possible to prevent the sudden refraction of the tube 600 drawn by the curved surface of the constant curvature formed in the first guide panel 460 and the second guide panel 530. In addition, the distance between the pair of width adjusting members 532 mounted on the second guide panel 530 is adjusted to contact both sides of the tube 600, thereby inducing a stable moving direction of the tube 600. Of course, the thermal curing of the conventional tube 600 is then progressed and attached to the inner surface of the conduit 500.
