[0006]

BEST MODE FOR CARRYING OUT THE INVENTION To explain the present invention with reference to an embodiment shown in FIGS. 1 to 8, a corrugated tube (1) shown in FIG. 1 has a convex ring portion (1A) and a concave groove portion (1B). They are arranged alternately and are made of thermoplastic synthetic resin such as polypropylene, polyethylene, polyester and polyvinyl chloride.

The corrugated pipe (1) is bundled in plural lines by the pipe concentrators (2, 2A) shown in FIGS. 2 and 3.
The tube concentrator (2,2A) is provided with a notch (4,4A) at the lower end C
A plurality (3) of V-shaped tube support frames (3, 3A) and the tube support frames
It consists of a connecting beam (5,5A) that connects (3,3A) at the upper end,
The plurality of pipe support frames (3, 3A) are connected so as not to interfere with each other by shifting their front and rear positions, and in this embodiment, the central pipe support frame (3, 3A) is connected to the recess of the corrugated pipe (1). The groove (1B) is arranged one pitch ahead of the pipe support frames (3, 3A) on both sides. Further, on the upper side of the connecting beam (5A) of the tube focusing tool (2A) shown in FIG. 3, an arcuate tube receiving frame (6A) is provided at a position corresponding to the tube supporting frame (3A).
Is provided.

The pipe concentrator (2, 2A) is made of the same thermoplastic synthetic resin as the corrugated pipe (1), and the corrugated pipe (1) is attached to each pipe support frame (3, 3A) as shown in FIG. Consolidate multiple articles (3 articles). In this case, the recessed groove (1B) of the corrugated pipe (1) is fitted through the notch (4, 4A) of the pipe support frame (3, 3A), but the corrugated pipe (1) is fitted. At this time, the tube support frame (3, 3A) elastically deforms and expands in the width direction.

The corrugated pipe to the pipe support frame (3, 3A)
In order to facilitate the fitting of (1) and to strengthen the supporting force (gripping force) of the pipe supporting frame (3, 3A) with respect to the corrugated pipe (1), the pipe supporting frame (3, 3A) shown in FIG. It is preferable to set the opening angle θ of the notch portion (4, 4A) of 3A) to 70 ° to 110 °.

The corrugated tube (1) is thus converged by the plural-line tube concentrator (2, 2A), but as shown in FIG. 5, the corrugated tube (1) converged by the tube concentrator (2A) is Further, as shown in FIG. 6, the corrugated tubes (1) focused on the tube focusing tool (2) are stacked. At this time, the pipe receiving frame (6A) of the lower tube concentrator (2A) is fitted into the concave groove portion (1B) of the upper corrugated pipe (1). In this way, the six-row corrugated pipe (1) is focused in three rows and two stages. In this way, it is possible to easily focus a plurality of corrugated pipes (1) by the pipe converging tool (2, 2A) on the site, and it is not necessary to bundle the pipes in advance with a band.

In the present invention, the tubes may be focused in four rows or more and three rows or more. In this case, the top row is the tube concentrator (2)
And the lower row is focused by the tube focusing tool (2A).

A filling member (7) is filled in the mutual gap of the focused corrugated pipes (1) as shown in FIG. As shown in FIG. 7, the filling member (7) has a predetermined number of irregular shaped square pieces (7
(A) is connected by a connecting portion (7B),
The peripheral portion of (7A) is fitted and filled in the concave groove portion (1B) of the corrugated pipe (1). By using the filling member (7), it is possible to prevent the ground surface from sinking due to the gap between the pipes. In order to connect the tubes (1) thus converged to each other, as shown in FIG. 8, one of the tubes (1) has a receiving portion (1) having an outer diameter substantially equal to the outer diameter D of the tube.
C), the other pipe (1) is provided with a small diameter portion (1D) having an outer diameter substantially equal to the inner diameter of the receiving portion (1C), and the small diameter portion (1D) is provided to the receiving portion (1D).
Insert it in C). In such a connecting structure, the outer diameter of the connecting portion is set within the outer diameter of the corrugated pipe (1).

In the present invention other than the above embodiment, FIG.
As shown in, multiple pipe support frames (3B) above and below the connecting beam (5B).
It is also possible to use a tube concentrator (2B) in which the front and rear positions are shifted from each other. In the tube focusing tool (2B), the upper and lower tube support frames (3
The corrugated pipe (1) is fitted into each of the B) via the notch (4B). Thus, the corrugated tube (1) is converged in two stages by one tube converging tool (2B). Further, the pipe focusing tool (2B) may be used to focus the corrugated pipe (1) in three stages as shown in FIG. In this case, the tube focusing tool (2B) alternately focuses the first and second tubes and the second and third tubes. Further, in FIG. 11, the tube support frame (3C) of the tube concentrator (2C) may have a U shape having a notch (4C), or the tube receiving frame (6C) may have a dogleg shape. Good.

[0014]

As described above, according to the present invention, a plurality of corrugated pipes can be tightly focused and the piping space can be made compact. Then, due to the mutual interference of the pipes, the deformation of the pipes due to earth pressure is prevented. If the filling members are filled in the gaps between the pipes, the pipes are less likely to be deformed by the interference of the filling members, and the depression of the ground surface can be prevented.
