かしい。 A construction method has been developed and implemented in which the inner surface of installed metal pipes is coated with thermosetting resin to prevent fluid leakage. This construction method is an excellent construction method that can prevent the fluid inside the pipe from leaking from gaps and holes that occur at the joints of metal pipes.
When a branch pipe is connected to a metal pipe, there is a drawback that the opening that connects to the branch pipe is covered by the coating film. Therefore, after applying the coating, it is necessary to remove the coating film that blocks the opening. However, since the branch pipe is connected to other branch pipes, the coating cannot be removed from the branch pipe and must be removed from within the main pipe. However, the main pipe is buried underground and can be over 300m long, so even if a jig is inserted to remove the coating, it is difficult to stop the jig precisely at the opening location. That's difficult.

検出し、開口部のコーテイング膜を除去する装置
が必要となる。 Therefore, there is a need for a device that accurately detects the position of the opening from inside the tube and removes the coating film at the opening.

30570 and Japanese Patent Application No. 56-1949, an opening detection device for a buried pipe has been proposed. In both cases, a cart equipped with a sensor that detects the position of the opening is inserted into the main pipe and moved within the main pipe. By the way, buried pipes are not only straight sections, but also have curved sections. Since the above-mentioned opening detection device detects the opening from within the main pipe, the cart equipped with the sensor must be able to run smoothly inside the main pipe, regardless of whether it is in a straight line or a curved section.

2, 7, and 8, and the pre-sensor 14 connects to the main pipe 1.
After detecting the rough position of the opening 16 of No. 5, the device is stopped. Then, the cart travels a certain distance (for example, about half the distance between the auxiliary carts 7 and 8) due to inertia and then stops. That is, the opening 16 is located between the auxiliary carts 7 and 8. Next, by rotating the motors 6, 12, and 13, the main sensor 4 is rotated around the tube axis and simultaneously moved in the tube axis direction, thereby scanning the inner surface of the main tube and positioning the opening 16. Detect accurately. When the main sensor detects the opening position, motor 1
2 and 13 are stopped, only the motor 6 is further rotated by a preset angle, and the drilling jig 5 is rotated.
is positioned at the opening 16. Next, the drilling jig 5 is pushed out in the radial direction of the main pipe 15, and a hole is drilled into the coating film C at the opening 16.
The main pipe 15 and the branch pipe 17 are communicated with each other.
