FIG. 1 is a schematic diagram of a pipe for carrying out a method of passing a wire through a pipe according to an embodiment of the present invention. In FIG. 1, 1 is a main pipe, and a branch pipe 3-1 is provided on the upstream side of the main pipe 1,
3-2, 3-3, 3-4 are branched, and branch pipes 5-1, 5-2, 5-3, 5-4 are branched downstream of the main pipe 1.
In the pipe branched in this way, for example, a branch pipe 3-
2 is arranged between the branch pipe 5-3 and the branch pipe 5-3 (when conducting a wire), the other branch pipes 3-1, 3-3, 3-4,
An obturator 7 is provided at 5-1 5-2 5-4.

ために設けられる。Next, the reel 9 around which the wire 13 is wound is placed in the opening of the branch pipe 3-2. FIG. 2 is an enlarged view of the reel 9, in which one wire 13 is multiply wound.
The reel 9 is provided with a tractor 11 made of, for example, cloth. The tow tool 11 is provided to efficiently receive the suction force of the suction device.

配置される。Next, the suction device 15 attached to the branch pipe 5-3 is driven to suck gas such as air in the pipe. In this case, no gas can flow in or out of the branch pipes other than the branch pipe 3-2, so that the gas is sucked from the branch pipe 3-2 and the tractor 11 is sucked to the suction device 15 side accordingly. At this time, while the wire 13 is unwound from the reel 9, the reel 9 moves in the pipe and the wire 13 is arranged in the pipe.

できる。By driving the suction device 15 in this way, the wire rod 1 is provided between the branch pipe 3-2 and the branch pipe 5-3.
3 can be arranged. In this case, since the reel 9 moves while unwinding the wire 13, the wire 13 itself does not move in the pipe, and it is not necessary to consider the frictional force between the wire 13 and the pipe. Therefore, the wire rod 13 can be reliably arranged even if the pipe is long or the pipe has many bends.

In this example, four blades 17 are provided in the reel 9. By providing the blade 17 in this manner,
Even if the suction force of the suction device 15 is strong, the reel 9 rotates in the direction in which the wire rod 13 is unwound from the reel 9, so that the wire rod 13 does not break, and the pipe length is long or the pipe is bent The wire 13 can be reliably arranged.
