When the installation of the repair member 10 is completed as described above, the retraction arm 220 is removed to collect the split sleeve 221 and shrink. Then, the repair member 10 maintains the state in close contact with the inner wall of the pipeline P, and only the repair device of the present invention can be taken out.

The operations described with reference to FIGS. 11A through 11D may be repeatedly performed when it is necessary to continuously install the repair member 10 in one pipeline P. FIG. In this case, unlike the conventional type in which the airbag conceals both ends of the repairing member, the present invention can secure a field of view that continuously observes both ends of the repairing member 10 by using the cameras 400 and 600, and thus the repairing member 10 is interposed therebetween. It can be installed precisely with little allowance for seams.

FIG. 11E shows the removal of the foreign material 50 in the inner wall of the pipeline P that prevents the correct installation of the repair member 10 before installing the repair member 10 in the pipeline P. To this end, the tool mounting machine 510 is equipped with a cutting edge 550 and removes foreign substances in the vicinity of the pipe P member to be installed using the mounted cutting edge 550. In FIG. 11E, as long as the tool mounting machine 510 is rotated 180 ° in the rolling direction and the height of the cutting edge 550 is precisely adjusted by the hydraulic cylinder 540 to remove the foreign matter adhering to the upper portion of the inner wall of the pipe P. You can see it. At this time, the retracting arm 220 is radially advanced to the expanded state in which the split sleeve 221 is opened. As a result, the repairing apparatus of the present invention is stably supported without bias in the pipeline P, so that it is possible to smoothly perform ancillary work that may require precision as needed. On the other hand, the camera 400 is angled toward the working site to observe the working state. This operation is mainly performed before the operation described in FIG. 11A to facilitate the installation of the repair member 10, but after the installation of the repair member 10 or during the installation, the tool mounting machine 510 is installed. Other tools, such as rolling rollers, can be mounted to perform a variety of tasks.

Subsequently, an unexcavated pipeline repair apparatus according to a modified embodiment of the present invention will be described.

12 is a plan view partially cut to explain a non-excavated pipeline repair apparatus according to a modified embodiment of the present invention.

As shown, in the modified embodiment of the present invention there is a difference in the configuration of the main body 100 'and the retraction means (including 210,231,241) compared to before the deformation. In a modified embodiment the main body 100 'is characterized by consisting of a plurality of combinations of the partial body (100A, 100B) and the retraction means (210, 231, 241 included) is configured to be suitable for the main body 100' having such characteristics do.
