Here, in order to pull the piping unit 8 into the laying pipe 3, it is necessary to run wheels mounted on the support frame 5 on the guide rails 4. At this time, the wheels may fall off from the guide rails 4. It is important to prevent
For this purpose, as shown in FIG. 7, the guide rail 4 installed at the lower part of the inner peripheral surface of the laying pipe 3 is, for example, U-shaped or U-shaped.
A channel-shaped rail typified by a steel material such as a channel steel having a U-shaped cross section is applied, and a wheel 12 attached to a lower portion of the support frame 5 is placed in a groove 4a of the guide rail 4,
The structure is such that the wheels 12 run in the grooves 4a of the guide rail 4. The wheels 12 are arranged inside a cover 13 fixed to a lower portion of the support frame 5.
Is fixed to the support frame 5 via the cover 13 so as to be rotatable.

That is, the channel-shaped guide rail 4
When traveling on the guide rail 4, the wheel 12 does not climb over the side wall 4 b of the guide rail 4, not only in the straight section of the laying pipe 3, but also in the curved section. Thus, the support frame 5 can be stably pulled in over the entire area of the laying pipe 3. In particular, the height h of the side wall 4b of the guide rail 4 shown in FIG. 7 (b) is not less than 3, preferably not less than の of the diameter D of the wheel 12.
This is advantageous for preventing the wheels 12 from falling off the guide rails 4.

The side wall 4b of the guide rail 4 and the wheel 12
, That is, the difference w−t between the groove bottom width w of the guide rail 4 and the thickness t of the wheel 12 is about 5 to 10 mm, which is advantageous to facilitate the drawing in the curved section. That is, in the curved section, the support frame 5 guided into the laying pipe 3 must be run on the guide rail 4 in an oblique direction with respect to the straight section, and the inclination for the straight section is absorbed. A gap is required between the side wall 4b of the guide rail 4 and the wheel 12. For this purpose, the groove bottom width w needs to be larger than the thickness t of the wheels 12, but if the gap between them is too large, the running of the support frame 5 becomes unstable, and stable pull-in is hindered. Will be. From such a viewpoint,
The difference between the groove bottom width w of the guide rail 4 and the thickness t of the wheel 12 is 5
It is recommended to be about 10mm. It is preferable to provide a gap of about 5 to 10 mm between the cover 13 of the wheel 12 and the side wall 4b of the guide rail 4 for the same reason.
