Abstract

PURPOSE:To make special treatment for external force and corrosion unnecessary by laying a communication cable or a protecting pipe with the communication cable inserted through on the outer surface of a pipeline as well as applying resin coating on the outer surface of the pipeline or fixing a coating material with the protecting pipe built in. CONSTITUTION:A communication cable 3 is laid outside a pipeline 1, and a resin coating 2 is applied on the communication cable 3 through adhesive. The communication cable 3 is thus clamped by the resin coating 2 so as to be fixed at the piping 1. No problem is generated in case the communication cable 3 is provided inside the pipeline 1. Moreover, as the communication cable 3 disposed outside the pipeline 1 is directly protected by the resin coating 2, special treatment against external force and corrosion as well as a special installation space become unnecessary.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to multifunctional piping that has a fluid transport function as well as communication and power transmission functions.

[Prior Art] Recently, attempts have been made to transmit various information between a sewage treatment plant and a pumping station using, for example, a sewage pipe.

In this case, a method is to lay a dedicated protective tube for communication cables, power transmission cables, etc. (hereinafter simply referred to as communication cables) outside the fluid transport piping, and run the communication cables through it.

Alternatively, there are methods such as passing the communication cable through the pipe without fixing it, or fixing the communication cable at the top of the sewer pipe with an anchor. In this case, it is possible to use a robot to fix the communication cable with reeding force. being done.

[Problems to be Solved] However, in the case of laying communication cables outside the piping as described above, 1. A place outside the pipe will be exclusively used for laying the communication cables.

2. Even if a protective tube is used exclusively for communication cables, there are problems such as the need to have strength against external forces and corrosion resistance.

Furthermore, the method of passing communication cables through piping has the following problems.

1. The communication cable may dance or vibrate due to the internal fluid, causing fatigue failure and breakage.

2. The internal fluid may damage the coating of the communication cable, causing it to lose its function as a communication cable.

3. The coating material of the communication cable may dissolve into the internal fluid, reducing the quality of the internal fluid.

4. If the internal fluid is tap water, it may be unsuitable for drinking water.

5. May require expensive robots.

An object of the present invention is to provide multifunctional piping that can solve the above-mentioned problems.

[Means for Solving the Problems] The multifunctional piping of the present invention includes laying a communication cable or a protection pipe into which the communication cable is inserted on the outer surface of the piping, and applying a resin coating to the outer surface of the secondary piping, or coating the outer surface of the piping with a resin. It is constructed by fixing a 'tj1m material in which a communication cable or a protective tube through which the communication cable is inserted is embedded. If a protective tube is provided, a communication cable is inserted into it.

[Operation] Since the communication cable is arranged outside the piping, the above-mentioned problem when the communication cable is provided inside the piping does not occur. In addition, communication cables installed outside the piping are protected by resin coating or coating material either directly or through a protective tube, so there is no need for special measures against external forces or corrosion, and no special installation space is required. do not need. Furthermore, if a communication cable is inserted into the protection tube, if the communication cable is damaged, it can be removed and repaired (or a new communication cable can be passed through the protection tube again).
Fluid piping can be easily repaired in its original state.

[Example] An example of the present invention will be described below with reference to FIG. A communication cable 1 is laid outside the piping 1, and a resin 1ff12 is applied to its L through an adhesive. In this way, the cable 3 is fixed to the pipe 1 by being sandwiched between the resin coatings 2. Examples of the resin coating 2 in this case include polyethylene coatings, vinyl chloride coatings, and the like.

FIG. 2 shows that the protective tube 4 through which the communication cable is inserted is
As in the case shown in the figure, it is fixed to the piping 1 with a resin coating 2. In this case, after laying the piping, insert the piano wire into the protection tube 4 using a piano wire rotating machine, etc., then connect the communication cable 3 to the rear end of the inserted piano wire, and connect the communication cable 3 to the rear end of the inserted piano wire. The communication cable 3 is pulled into the protective tube 4 by a laying pulling machine.

Next, another embodiment will be explained with reference to FIG. In this case, a covering material 2a in which a communication cable 3 is embedded is fixed to the outside of a pipe 1 via an adhesive. The covering material 2a in this case is, for example, polyethylene or vinyl chloride.

FIG. 4 shows a case where a covering material 2C in which a protective tube 4 through which a communication cable 3 is inserted is embedded is fixed to the outside of the piping 1 via an adhesive. In this case as well, after laying the piping, insert the communication cable 3 into the protective tube 4 in the same way as in the case of Fig. 2.
Insert.

In addition, as shown in FIG. 5(a), a covering material 2C in which a wire 5 coated with a female molding agent for drawing in the communication cable 3 is embedded is fixed to the pipe 1, and this wire 5 is used for communication. By connecting the cable 3 and drawing the communication cable 3 into the covering material 2C using the wire 5, the third
It is also possible to construct multifunctional piping similar to the one shown in the figure.

In addition, as the communication cable 4, an optical fiber telephone line,
There are coaxial cables, power transmission cables, etc.

[Effects of the Invention] The multifunctional piping of the present invention is as described above, and the communication cable is installed outside the piping, so the problem described in item t does not occur when the communication cable is installed inside the piping. . Also,
Communication cables installed outside the piping are protected by resin coating or coating material either directly or through a protective tube, so they do not require special measures against external forces or corrosion, and do not require special installation space. do not. Furthermore, when a communication cable is inserted into a protection tube, if the communication cable is damaged, the fluid piping can be left as is by pulling out the communication cable and passing a repaired or new communication cable through the protection tube again. can be easily repaired.
