The hardening process can be performed, and the repair work in the pipeline can be performed without any trouble on the road traffic. Also, since the sliding material before and after the device is a brush type, the inner surface of the pipeline is cleaned with a brush by the movement of the device, and even if there is an obstacle of pebbles in the pipeline, the brush can get over, furthermore, Since the outer diameter of the brush is substantially the same as the inner diameter of the pipe to be repaired (pipe), the repair surface is cleaned over the entire circumference, and smooth repair is possible. In addition, since the sliding material is detachably fixed on the inner pipe, the sliding material can be appropriately changed to a sliding material having a size corresponding to the diameter of the repair target pipe, and a good cleaning effect can always be expected.

It is possible to run inside the pipeline. Furthermore, since the sheet-like repair material is crimped and fixed and has almost no protrusion inside after repair, there is no running water resistance in the case of sewer pipes, and in the case of conduit pipes, it is necessary to draw wire. There is no hindrance.

If the unsaturated polyester resin is left for a certain period of time even when pressed, the unsaturated polyester resin is cured. Propagation proceeds quickly and uniformly, shortening the curing time. In addition, since the area occupied by the large-area opening on the outer tube peripheral surface was set to 50% or more, the heat propagation of the heater 9 was so good that the existence of the non-opening portion on the outer tube peripheral surface was substantially negligible. .

線の引き入れ抵抗のない補修が出来る。[Effect of the Invention] According to the device of the present invention, the repair work of the pipeline does not need to prevent the flowing water in the pipeline as in the related art as long as the defect position of the pipeline is specified, and the repair device itself is repaired. The repair material is pressed and hardened on the inner surface of the pipe while flowing the water in the pipe through the inner pipe 1 of the apparatus, and the inner face of the pipe can be repaired only by sending the water to the position. And since the sheet-like repair material has only been solidified by crimping at the repair location on the inner surface of the pipeline after repair,
Since there are no protrusions and the inner surface of the pipeline can be repaired smoothly, it can be repaired without drainage resistance in the case of sewage pipes and without resistance to pull in electric wires in the case of conduits.

出来る。Further, since the repairing device has a built-in heater, the resin curing treatment of the repairing material can be quickly achieved. Furthermore, since the heat of the heater is quickly and evenly transmitted into the expanded rubber tube from the large-area openings scattered in the outer tube,
The heat treatment efficiency is greatly improved. Furthermore, since the sliding material is larger than the outer diameter of the outer tube of the apparatus, the sliding member is not loosened on the rubber tube of the outer tube even when sliding in the pipeline, so that the repair material is not damaged. Pasting can be performed neatly.

することにより、滑走用材の機能を有効に発揮できる。Also, since the heater is a heater with a built-in heating means, there is no need to receive a heat source from the ground during the repair work. Therefore, the work can be performed with the manhole closed without any hindrance to road traffic. Can be performed. In addition, since the sliding material is sandwiched and held by the flexible plate material and the outer diameter is substantially the same as the inner diameter of the pipeline, the inner surface of the pipeline can be cleaned at the time of sliding.
In particular, when the sliding material is of a brush type, even if there are pebbles or the like in the pipeline, smooth sliding can be performed without any trouble. In addition, since the sliding material is detachable, the function of the sliding material can be effectively exhibited by replacing and mounting the sliding material corresponding to the target pipeline diameter.
