Abstract

PURPOSE: A cable duct pipe for electric wires and communication lines is provided to easily and fast perform a railway work by grasping a position of a communication line and an internal cable tube. CONSTITUTION: A plurality of guide projections(2) are inwardly formed inside a duct(1) in a radial and integral manner. A cable tube(3) is interposed between the inward guide projections(2) to permit wires and communication lines to be led therein. Accordingly, the cable tube(3) or the communication cable is not deformed, thereby preventing short or bent. The guide projections(2) are interposed between the four cable tubes(3), so as to support the cable tubes(3) and prevent movement of the cable tubes(3) during a railway work. When a diameter of the cable tube(3) is small, there may occur a slight movement between the guide projections. At this time, only one independent cable tube(3) is slightly moved and thus functions as a catalyzer when the wires and communication lines are laid. Rather, the wires and the communication lines are softly pulled and workers can easily work.

Description

Duct pipe cable for correspondence wire and electric wire

The present invention relates to a duct pipe for wiring an electric wire cable, a communication line cable, and an optical fiber cable, and is formed integrally so that a plurality of guide protrusions are directed inwardly on a large inner surface of the duct pipe, and an electric wire is formed between the guide protrusion and the guide protrusion. Or it relates to a cable duct pipe for the wire, the communication line is invented so that the cable pipe is inserted into the communication line is placed so that a plurality of wires sandwiched inside the duct pipe during wiring and line work can be easily twisted with each other.

Conventional wire or communication cable is to be inserted in a large appearance, the twisting occurs during the line work to penetrate between the manhole and the manhole of several ten meters, wires are short-circuited or bent, so discard the expensive cable Or there was a problem to re-work.

That is, in order to bury an electric line or a communication line underground, a large diameter pipe was buried between the manhole and the manhole, and a concentric wire cable for an electric line or a communication line was buried inside the large diameter pipe.

In order to bury the cables for electric and communication lines in such large diameter pipes, the pipes first pass through the large diameter pipes between the manholes and the manholes, and the wires are connected to the connecting pipes to keep the wires through the large diameter pipes. After connecting the concentric wire cable for the communication line to one end of the wire to pull the wire to penetrate the diameter pipe, but for the large diameter pipe between the manhole and the manhole is not easy to work through the insertion pipe and wire insertion, manhole Insertion of the cable cable for the line in the large diameter pipe between the hole and the manhole has become very complicated. Especially, if the cable is pulled forcibly in the twisted or twisted state due to the twisting of the cable, the communication line will be shorted. Delays in working time and expensive cable The problem was that yohage labor.

The present invention has been invented in view of the above problems,

A plurality of guide protrusions are formed integrally inside the duct pipe through which the electric wire cable and the communication line cable pass.In between the inward guide protrusion and the guide protrusion, a cable pipe into which the wire and the communication line are introduced is located. Do not twist the pipes individually, and form one or more fixing protrusions on the outer surface of the duct pipe and use them as fixing keys when connecting the duct pipes. It is invented to be.

According to the present invention, a plurality of guide protrusions 2 are formed radially inwardly in the duct pipe 1, and the wires and communication lines are introduced between the guide protrusions 2 and the guide protrusions 2 inwardly. Pipe (3) is positioned to prevent the cable pipe (3) and cable pipe (3) or communication line cable from twisting during the line work to prevent short-circuit or bending.

In the present invention configured as described above, two or more guide protrusions 2 radially installed inside the duct pipe 1 are positioned between four cable pipes 3 into which the wire cables or the communication wire cables are inserted. At the same time as supporting the cable pipe 3 as shown in the cable work (3) there is no flow during the line work is not a twisting phenomenon.

In this case, when the diameter of the cable pipe 3 inserted between the guide protrusion 2 and the guide protrusion 2 is small, some flow may occur between the guide protrusion 2 and the guide protrusion 2 without being fixed. This can be done smoothly by acting as a catalyst when penetrating wires and communication lines, because only one independently located cable pipe 3 is slightly moved without twisting with other cable pipe 3 introduced into the duct pipe 1 during the line work. It is pulled and penetrated so that workers can work easily.

Examples of the present invention made as described above are as follows.
