Description

DETAILED DESCRIPTION OF THE INVENTION (Hereinafter, the field of application, prior art, and other objects of the invention) The present invention relates to an in-pipe wiring method. For example, when repairing the inner surface of a pipe such as a buried pipe using a resin seal method, there is first a cleaning process of cleaning the inside of the pipe, and then a repair process of sealing with resin.

In any case, in order to tow the cleaning tool or repair equipment, it is necessary to run a wire from one side of the tube to the other. Conventionally, there is an example of such a wiring method in which the parachute is moved by wind pressure, but dust 1. When there are many foreign objects, or when the inner wall of the pipe is wet with water, oil, etc., the parachute often gets caught or closes, making it impossible to pass the wire through, which is impractical. In the present invention, a light balloon is moved by air blowing or suction, so that wires can be passed without difficulty even under the above-mentioned adverse conditions. The details will be explained below with reference to the figures. (
(Structure and operation of the invention below) Reference numeral 1 is a linear body, and 2 is a light balloon like a Bing Pong ball provided at one end of the linear body 1. The light balloon 2 is inserted into a pipe body 3 such as a buried pipe, and the light balloon 2 is blown or sucked from one side of the pipe body 3 by a blower 4 or a suction device 5. The linear body '1 connected to the light air balloon 2 is passed through the tube body 3 by moving from the cutting point A to the other cutting point B. When the light balloon 2 is moved, even if there is dust or foreign matter inside the tube body 3, or even if the inner wall of the tube is wet with water, oil, etc., the light balloon will bounce on the wind. ) and moves within the tube body 3 without difficulty. In particular, when there is a lot of water difference in the pipe body, mud dissolved together with the difference water enters the pipe, and as the gas becomes dry, it becomes deposited on the bottom of the pipe. If there are loose deposits on the pipe wall, the conventional parachute method will not be able to actually pass through the line because it will get caught in the deposits or get caught again and become closed. . In the present invention, the light balloon is moved by the wind, so even if the above-mentioned deposits are present, the light balloon moves bouncingly and can be easily routed. When threading the wire body 1, it is best to use a light one, and once the wire is threaded, it may be gradually made stronger. This wiring enables the process of towing the cleaning tool and the repair process described above. (Hereinafter, the effects of the invention) As described above, the present invention allows the light balloon to be carried by the wind and be moved without difficulty despite the adverse conditions inside the pipe, and the wire can be routed. Above all, since the members used are simple, there is a great advantage that the wire can be run at an extremely low level.

The present invention has been described with reference to the case where wires are passed through a pipe body such as a buried pipe, but the present invention is not limited to a buried pipe, and can also be applied to a wide range of wires (for example, when passing a communication line through a pipe). Of course, it can also be applied.
