And, as shown in Figure 11, after exiting all from the cylindrical drum 110 to the rear end 210 of the tube lining material 200, and after passing through the bent portion between the manhole 11 and the conduit 10 is less resistance In this case, the inverted control line connected with the heat medium supply pipe 181 to the rear end 210 that the bent portion of the tube lining material 200 rapidly run reversed by air pressure while the rear end of the tube lining material 200 passes through the curved portion. By being suppressed by 183, the pipe lining material 200 can be reversed naturally and can be drawn in slowly.

As shown by the imaginary line of FIG. 11, in the state in which the rear end 210 of the pipe lining material 200 is advanced to the other opening side of the pipe line 10 and completely reversely inserted, the reverse nozzle 155 is cut off. Alternatively, after separating from the tube lining material discharge pipe 151, the separated reverse nozzle 155 is coupled to the cover 157 covering the manhole 11, as shown in FIG.

In addition, the airtight lid 158 is coupled to the end of the inversion nozzle 155 to seal the tube lining material 200 to maintain airtightness with the outside.

In the above state, the recovery pipe 185 is inserted into the tube lining material 200 through the airtight lid 158, and pressurized air is used by using a compressor not shown in the tube lining material 200. It is supplied and brought into close contact with the inner wall of the pipeline 10. In this state, when the heat medium such as hot water or steam is supplied from the hot water supply unit 181 to the heat medium supply pipe 181, the heat medium is sprayed from the heat medium supply pipe 181 to maintain a state of being in close contact with the inner wall of the conduit 10. By heating and hardening the existing pipe lining material 200, the pipe line 10 can be repaired. Then, the hot water in the pipe lining material 200 is drawn out to the outside by the driving of the pump 320 through the recovery pipe 185 to be recovered.

Thus, when using the tube lining material reversing apparatus 100 according to an embodiment of the present invention, after transporting in a state separated into the lower drum 111 and the upper drum 113 of the cylindrical drum 110, in the field Since it is assembled in a cylindrical drum shape it is possible to wind the longer tube lining material 200 therein than in the conventional.

For example, as shown in FIG. 10, assume that the height limit H of the vehicle is 3.8 m in road traffic. In addition, in the case where the height h1 of the normal truck, that is, the transport vehicle 30 is assumed to be 1.0 m, as shown in FIG. Becomes 6.16 m 2.

On the other hand, as in the embodiment of the present invention, by manufacturing the cylindrical drum 110 in the medium type (I), it is possible to divide the lower drum 111 and the upper drum 113, the lower drum 111 and the upper drum The height of the cylindrical drum 110 after joining 113 becomes 3.6m, and the area of a side surface becomes 10.18m <2>.

In the cylindrical drum 110 'of the large size type II, the height of the cylindrical drum 110' after the lower drum and the upper drum is joined is 4.0 m, and the side surface area is 12.57 m 2. The increase in the area of the side surface of the cylindrical drum 110 ′ is proportional to the increase in the winding length of the tube lining material 200. Therefore, in the cylindrical drum 110 'of the large size type II, the tube lining material 200 of about twice the length of the conventional cylindrical drum 20 can be wound up. The effect calculation table can be detailed in Table 1 below.

division Height (m) Side area (㎡) Magnification Comparative example (traditional cylindrical drum) 2.8 6.16 1.00 Experimental Example 1 (Type I) 3.6 10.18 1.65 Experimental Example 2 (Type II) 4.0 12.57 2.04

As described above, the cylindrical drum 110 is divided into the lower drum 111 and the upper drum 113, thereby being transported and assembled to the construction site in a divided state, thereby allowing the large diameter cylindrical drums 110 and 110 'to be assembled. You can get it. Therefore, since the pipe lining material carried to the construction site can be wound longer than before, construction of a long distance is naturally possible, and the installation location of the tunnel for insertion of the pipe lining material 200 can be reduced, thereby reducing costs. The effect can be expected, and as the length of construction increases, two constructions can be possible with one construction, which can greatly reduce construction costs and minimize traffic obstacles on the surrounding roads. There is an advantage to that.

Hereinafter, a method of winding and inverting the tube lining material 200 in the tube lining material inverting apparatus 100 according to the embodiment of the present invention having the above configuration will be described in detail.

First, as shown in FIG. 3, the cylindrical drum 110 having the structure separated into the lower drum 111 and the upper drum 113 is mounted on the transport vehicle 30 in a separated state and transported to the construction site.

Upon arriving at the construction site, as shown in FIG. 5, the separated upper drum 113 is assembled on the upper portion of the lower drum 111.

In the state in which the cylindrical drum 110 is assembled, as shown in FIG. 8, the tube lining material 200 transported to the construction site using a separate transport vehicle 60 is a tube lining material of the cylindrical drum 110. It enters into the insertion hole 141 and winds up.

That is, as shown in Figure 6, the rear end of the tube lining material 200 is connected to the heating medium supply pipe 181 and the control line 183, which is pre-wound on the rotary shaft 120. And the passage line 187 is installed in advance so as to pass through each of the tube lining material insertion port 141 and the tube lining material discharge pipe 151.

In this state, the tube lining material 200 is wound around the rotation shaft 120 while rotating the rotation shaft 120 in the direction of the arrow in FIG. 6. At this time, the inside of the cylindrical drum 110 can be adjusted so that the tube lining material 200 can be wound around the rotary shaft 120 uniformly.

Here, since the tube lining material 200 is about 1.57 times larger than the diameter of the folding in the flat state, when the tube lining material insertion hole 141 is circular, the tube lining material 200 should be folded in the width direction, but Since the tube lining member insertion hole 141 of the embodiment is formed in a rectangular shape at an arc portion behind the cylindrical drum 110, it is necessary to fold the tube lining material 200 in the width direction. It can be rolled up naturally. In addition, since the height of the tube lining material insertion port 141 may be greater than or equal to the thickness of the tube lining material 200, the tube lining material insertion port 141 may be processed to minimize the size of the tube lining material insertion port 141. .

On the other hand, after winding all the tube lining material 200 on the rotary shaft 120 in the same manner as described above, before the front end of the tube lining material 200 enters the tube lining material insertion hole 141, The tip 230 of the tube lining material 200 is connected to the passage line 187.

And the tow line 187 is pulled from the tube lining material discharge pipe 151 side, so that the tip 230 of the pipe rising material 200 to be drawn out toward the tube lining material discharge pipe 151.

In such a state, the reverse nozzle 155 is attached to the pipe lining material discharge pipe 151 and installed.

Then, the tip of the tube lining material 200 is inverted to be coupled to surround the outside of the inverted nozzle 155 attached thereto, and then firmly fastened to be hermetically sealed by the fastening band 156.

In this state, when the compressor 40 is driven to supply pressurized air into the cylindrical drum 110, the pressurized air is applied to the tip 230 of the tube lining material 200 in the direction of the arrow in FIG. 7 by the pressurized air. Is applied and discharged in reverse.

Then, the inverted pipe lining material 200 enters into the conduit 10 to be repaired through the manhole 11, as shown in FIG.

And, as shown in Figure 11, when entering into the pipe line 10 to the rear end 210 of the pipe lining material 200, the pipe lining material 200 can proceed even by a small air pressure, the rear end 210 The rapid runaway inversion of the pipe lining material 200 at the moment of passing through the bent portion between the manhole 11 and the conduit 10 may be suppressed by the inversion control line 183 so that the inversion may proceed slowly slowly. Therefore, it is possible to prevent damage to the tube lining material 200 or damage to other parts or devices due to the metal runaway reversal. That is, while the tube lining material 200 is wound around the rotation shaft 120, the rapid runaway reversal of the tube lining material 200 is controlled by air pressure, but the tube lining material 200 is withdrawn from the rotation shaft 120. In this case, it is not possible to control the rapid runaway reversal only by the tension force of the heat medium supply pipe 181, and in a worse situation, the heat medium supply pipe 181 may be pulled out and broken, but a reverse control line composed of a rope or a belt ( 183 is additionally installed and wound together with the heat medium supply pipe 181, thereby preventing rapid runaway reversal of the tube lining material 200.

11, when the tube lining material 200 is completely inverted and inserted, as described above, the inversion nozzle 155 is separated from the tube lining material discharge pipe 151 and then, as illustrated in FIG. 12. As shown, it is coupled to the cover 157, and its open end is installed to engage and seal the airtight lid 158.

And the recovery pipe 185 is installed to enter the inverted tube lining material 200. In this state, the inverting nozzle 155 to which the tube lining material 200 is connected is hermetically connected to an air pressurization unit, that is, a compressor, not shown, and the tube lining material 200 is in close contact with the inside of the pipe line 10. The hot water is sprayed on the inner wall of the pipe lining material 200 through the supply pipe 181 to cure the pipe 10. At the same time, the hot water can be recovered through the recovery pipe 185.

On the other hand, the above has been described by taking hot water as a heating medium as an example, but this is only illustrative, it is natural that the hot steam can be sprayed as a heating medium.

While the invention has been shown and described in connection with preferred embodiments for illustrating the principles of the invention, the invention is not limited to the construction and operation as shown and described. Those skilled in the art will readily appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
