As shown in FIGS. 4 and 5, the inner circumferential end surface of the closing plate 16 has a conical cutout 26 formed at the tip of the piston rod 25 of a seven-seater 24 connected to the hydraulic hose 17, similar to the straightening blade 12. As a result of the advancing movement, they move in the radial direction outside the outer case 11 and protrude and spread as shown in FIG. 4(b). The divided pieces of the blockage plate 130, which are almost the same size, are always subjected to a force in the direction of contraction by a spring (not shown), and the outer circumference thereof becomes the same as the outer circumference of the outer case 11 when it is contracted. A hydraulic hose 18.19 and a grouting hose 19.20 pass between each segment of the closure plate 16. The operating cylinder of the left-hand closing plate 13 in FIG. 1 is oriented in the opposite direction to that shown in FIG. 4. Crushing blade 16a,
As shown in FIGS. 6 and 7, 16b and 16c are conical pipes 29 formed at the tip of the piston rod 28 of the hydraulic hose 18, which is connected to the hydraulic hose 18 in the same way as the straightening blade 12 and the closing plate 16. As a result of the progressive movement of , it spreads toward the outer periphery as shown in Fig. 1(b). Immediately before each grout injection hole 14, as shown in FIG. A Y-tube is provided to send it.

管路32は第10図(e)に示すように矯正される。FIG. 9 shows the state in which the device of the present invention is inserted into a conduit and used. The device A of the present invention is connected to the rear of the television camera 31, and a wire rope 66 is passed through the conduit 62.
Connect the camera 61 to the control panel 64 and connect the hoses 18 and 19 to the control panel 64.
The grout base agent supply hose 19 and hardener supply hose 20 are connected to the base agent tank 68 and hardener tank 39 through pumps 36 and 37, respectively, and are connected to the camera 61 and the hardener tank 39. Put the invention device A into the pipe 32 and operate the winch 40 to remove the wire lobe 6.
At the same time, while winding the camera cable 41 around the cable drum 42, the camera 61 and the apparatus A of the present invention are pulled in, and the state inside the conduit 62 is photographed by the camera 61 and displayed on the television 42. Once the damaged area is confirmed using the camera 61 as shown in Figure 10(a),
As shown in FIG. 1'0(b), the straightening blade 12 is brought to the damaged area, and the piston rod 22 and the piston rod 25 are pushed forward by operating the hydraulic bomb processor 5 and the control panel 64. Expand 16. Thereby, the conduit 32 is straightened as shown in FIG. 10(e).

The mixture is fed under pressure, mixed by a Y-tube just before the injection hole 14, and discharged from the injection hole 14. As shown in FIG. 10(c), the grout discharged from the injection hole 14 comes out from the split portion of the pipe line 62 and covers the outer periphery of the split portion. Therefore, the control panel 64
is operated so that the straightening blade 12 and the closing plate 13 are contracted. Thereafter, the device A is moved to the front of the pipe by the winch 40 to crush the leaking grout, and then the winch 46 on the other side is rewound, as shown in FIG. 10(a).

When the repair device A is crushed, the crushing blade is retracted, and the winch 46 is then retracted to take out the repair device A from the pipe 62, and the grout attached to the repair device A is removed. At this time, the grout is not completely hardened and can be easily removed. Incidentally, the grout remaining in the grout injection hole 14 and other areas is also dissolved and removed using a solvent to prepare for the next use. After the repair device A is taken out of the pipe, a cloth or the like is passed through the pipe 32 several times to completely remove the grout remaining in the pipe 62. The grout that covers the outer periphery of the pipe solidifies completely, increasing the reliability of the repaired area by fixing the repaired part from outside the pipe.
