本発明は11小ロ径トンネル内へ通信ケーブル等を収容
する管路を引込む工法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a construction method for leading a conduit for accommodating communication cables etc. into an 11-small diameter tunnel.
(従来の技術)

る。(Prior art) Conventionally, as a method of drawing multiple pipes into a small diameter tunnel constructed by propulsion of humid pipes, etc., the methods shown in Figs. 5 and 6 are used.
As shown in the figure, pipe lines 1 are assembled in a stacked manner using spacers 4 on a structure made by processing steel materials, etc.
It is designed to be pulled into the tunnel 5 with a winch 6.
(発明が解決しようとする問題点)
上記従来の工法では、そり等の製作に要する費用も大き
く、また管路引込後も管路と共にトンネル内に残すので
再利用ができず、経済的に不利であった。さらにトンネ
ル断面の使用効率が低い等の問題点があった。(Problems to be solved by the invention) In the conventional construction method described above, the cost required for manufacturing the sled etc. is large, and since the pipe is left in the tunnel together with the pipe after the pipe is drawn, it cannot be reused, which is economically disadvantageous. Met. Furthermore, there were other problems such as low utilization efficiency of the tunnel cross section.
そこで、そり等を用いず直接管路に張力をかけて引込む

An elastic body 11 made of rubber or the like is sandwiched between the plate bodies 12 at the front and back at the rear, a bolt 13 that passes through the drawing plate body 12 and the elastic body 11, and a vibrator 14 inserted into the bolt 13. , a nut 15 for pressing this pipe 14 against the front plate body 12 and compressing the elastic body 11 to expand its diameter, and a nut 16 for fixing it to the jig main body 7.
, 17, the elastic body 11 of the conduit gripper 10 is made of
The rod 8 is inserted into the necessary number of pipes other than the pipe into which it was inserted and crimped onto those pipes, and fixed to the jig main body 7, which has a bowl shape with the outer periphery of the tip facing backward and forming a curved surface. The tip of the rod 8 is attached to the jig body 7 with a nut 18,
The tips of all the pipes enter into the jig main body 7. Next, as shown in Figure 1, five pipes 1, which are the smallest units that are structurally stable, are gathered into a triangular shape and bound with bands 19 as shown in Figure 1 (a). Then, as shown in the same figure (b), the other two pipes 1 are brought into close contact with this, and this is tied with the band 19 in a triangular shape with one of the pipes tied earlier.
Stack the two pipes 1 as shown in the diagram, tie together the two added pipes 1 and one pipe 1 from the triangular bundle, and finally from the top of the whole Furthermore, tie with band 19.

引込み作業を繰返して行なう。Even if the number of pipes is different, the pipes can be bundled using the same method. By making the tension of the band 19 stronger when the whole band is tied as compared to when the smallest unit is tied, the pipe can be brought into close contact, and step collapse can be completely prevented. Furthermore, the band 19 is tied near the socket 21 of the conduit 1 as shown in FIG. 4 in order to prevent the band from being worn out due to contact with the inner surface of the small-diameter tunnel. Next, the rear end of the wire 9 is attached to a towing hook 20 provided on the jig body 7, and the wire 9 is pulled into the tunnel 5 to near the rear end of the conduit 1 using the winch 6. A new pipe line 1 is connected to the rear end of each pipe line 1 that has been drawn in, and at this time, the rod 8 is also connected, each pipe line 1 is tied in the same manner as described above, and the tunnel 5 is closed using the winch 3 as described above. Pull inward. Thereafter, the pipes are connected, tied together, and the rods 8 are connected, and the work of pulling the pipes into the tunnel 5 using the winch 3 is repeated.

る。In that case, if you attach an anchor to the protruding end of the rod 8 from the conduit 1 to hold down the rear ends of all the conduits, this anchor will push the rear ends of all the conduits as they are drawn in.
Since no pulling force is applied to the conduit connection, even if there is a defective adhesive connection, separation at that part is prevented. Even if the anchor is not installed yet and only the rod 8 is attached, if the pipe should come apart at the pipe connection, pull the rear end of the rod 8 in the opposite direction and pull the pipe pulled into the tunnel 5. Route 1 can be pulled back. Once the pipe line 1 has been drawn in, the jig main body 7, pipe line gripper 10, rod 8, etc. are removed and recovered.

。(Effects of the Invention) As described above, according to the present invention, the pipe can be held by the pipe gripper without processing the pipe, and the rod can prevent the pipe from coming off at the connecting part. Alternatively, by attaching an anchor to the protruding end of the rod to hold down the rear end of all the pipes, it is possible to pull the pipes in without causing separation of the pipe connections. obtain. Furthermore, since the jig body is bowl-shaped, it can be retracted smoothly. In addition, by sequentially bundling five pipes into a stable hexagonal shape with a band and further bundling the outermost periphery with a band, the pipes can be drawn in closely together, and small diameter The tunnel cross section can be used effectively, and the pipe can be drawn in with high reliability without causing step collapse.Furthermore, the drawing jig can be removed after use and used repeatedly, reducing construction costs. , the economic effect is large.
