Description of the Related Art A seam portion between a main pipe and a branch pipe buried therein may be cracked or damaged due to deterioration, ground subsidence, vibration of a traffic vehicle, or the like. Conventionally, with respect to such damage, it is common that the portion is exposed by excavation work and repair work is performed from the outer surface side of the sewer pipe. Next, in such a sewer pipe, it is known that repair work is performed from the inner surface side of the pipe by a repair device.
In this, a pair of disc-shaped side lids is arranged at both ends of the shaft, and a cylindrical rubber material is airtightly attached between the outer peripheries of both discs,
A heater is provided at an intermediate portion of the shaft to send compressed air into the rubber tubular body so that the rubber tubular body can expand and contract. Then, a reinforcing cloth with a thermosetting water sealant (a curing agent, an accelerator, etc. is mixed in at the time of work) is attached to the outer periphery of the rubber cylinder as a repair material, and the repair device is installed inside the cracked pipe. Was inserted, compressed air was sent into the cylinder to expand the outer circumference of the cylinder, and the thermosetting water sealant on the surface of the heated repair material was adhered to the inner surface of the sewer pipe together with the reinforcing cloth. The heating by the heater at this time accelerates the curing of the thermosetting water sealant.

があった。The former method of performing the excavation work has a drawback that the work is large and troublesome. Further, the conventional device which is performed from the inner surface side of the pipe has the following drawbacks. (1) A heating device for adhering the repair material has to be provided on the shaft portion, but the rubber cylinder to which the repair material is adhered expands during the repair and comes into contact with the inner surface of the sewer pipe. Then, the gap between the heater and the rubber cylinder is widened, and it is difficult to efficiently heat the repair material. Especially when the repair material comes into contact with the inner surface of the pipe to be repaired,
There was a drawback that the repair material that had been heated to a certain extent was cooled and it was difficult to bond it to the inner surface of the pipe. That is, there is a drawback in that the reliability of adhesion and the speed of repair work are lacking. (2) Further, there is a drawback that the sewer pipe through which the waste water flows cannot be repaired in the flowing state. (3) Further, the rubber cylinder drive unit for aligning the repair material provided on the outer periphery of the rubber cylinder with the damaged portion of the sewer pipe has to be arranged outside the apparatus main body. Therefore, there is a drawback that the entire device becomes long and lacks compactness. or,
There is a risk that the drive unit may break down due to leakage of drainage or the like in the sewer pipe.

First, the protrusion amount of the shafts of the pair of drive wheels 27 of the traveling means 10 is adjusted according to the diameter of the repaired pipe 30. Then, the control cable 17 penetrating the side cover 8 on the right side of FIG. 1 in a liquid-tight manner is connected to a control device having a power source. Further, one end of the air hose 18 of the gas press-fitting means 5 shown in FIG. 4 is airtightly connected to the side cover 8, and the other end of the air hose 18 is connected to the compressor. At the same time, the ends of the wire are locked to U shackles 19 arranged at the front and rear ends in the axial direction of the device. Then, a cover for peeling is previously attached to the outer periphery of the rubber tube body 3, and then a repair material 34 is attached as shown in FIG. The repair material 34 is composed of a reinforcing cloth and a thermosetting water sealant applied to both surfaces thereof. The reinforcing cloth is made of a woven glass fiber cloth and a non-woven cloth. The thermosetting water sealant comprises a main agent, a curing agent and an accelerator. The device thus prepared is inserted into the repaired pipe 30. FIG. 8 shows a branch pipe 31.
It shows an example of repairing the bifurcation part. The drive wheel 27 of the traveling means 10 is rotated so that the central portion of the device in the longitudinal direction is the branch pipe 31.
Place it so that it is located at. For that purpose, a television camera (not shown) or the like may be inserted through the opening of the branch pipe 31, and the rotation of the drive wheel 27 may be controlled while monitoring.

The side lid drive motor 9 is rotated so that the opening provided at the center of 34 is aligned with the opening of the branch pipe 31. Therefore, the rubber cylinder 3
While heating the flexible heater 4 inside, the compressor is driven to expand the rubber tube body 3 in the radial direction as shown in FIG. Then, the repair material 34 is pressed against the inner surface of the repaired pipe 30. Then, the thermosetting water sealant of the repair material 34 is accelerated by the heating of the flexible heater 4 and adheres the repair material 34 to the inner surface of the repaired pipe 30. In this embodiment, after the repair material 34 to be joined to the inner surface of the branch pipe 31 is pre-bonded, a new repair material 34 is adhesively fixed to the inner surface of the repaired pipe 30 so that the ends of the repair material 34 overlap. I'm taking the way.
