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 cleaning tools or repair equipment, wires must be routed from one side of the tube to the other. Conventionally, as a wiring method, the parachute is moved by wind pressure, but if there is a lot of dust or foreign matter inside the tube, or if the inner wall of the tube is wet with water, oil, etc., the parachute may get caught.
This was impractical because it often closed, making it impossible to pass wires through. The present invention prevents the parachute from closing, and according to the present invention, the wire can be passed without difficulty even under the above-mentioned adverse conditions inside the tube. The details will be explained below with reference to the figures. (Hereinafter, the structure and operation of the invention) Reference numeral 1 denotes a parachute-shaped guide member, and the guide member 1 is configured to enclose a light sphere 2 such as a Sbonzo sphere or a Binmen sphere. The guide member 1 is also configured to be connected to a linear body 3, and the guide member 1 thus configured is inserted into the tube body 4.

The tube body 4, such as a buried pipe, is cut in advance at both sides of the desired repair point 50, and the wire is routed from one cut point A to the other cut point B. The guide member 1 having the above structure is inserted into the tube body 4 from the cutting point A, and the tube body 4 is removed using a blower or the like.
When the air is blown inward, the guide member 1 moves in the direction of the cutting point B under the wind pressure.

In this case, even if there is dust or foreign matter inside the tube body 4, or even if the tube inner wall is wet with water, oil, etc., the guide member 1 will remain open because it embraces the sphere 2. The guide member 1 is maintained and does not close (and moves by effectively receiving the wind pressure.
When the wire moves to the cutting point B, the wire passing through the pipe body 4 is completed at the same time. The linear body 3 connected to the guide member 1 should be thin and light when passing the wire through, and it is sufficient to make the wire body 3 sequentially strong from the wire passing 1 to the other. This wiring makes it possible to carry out the work of towing the cleaning tool and the repair work described above.

(Hereinafter, the effects of the invention) Since the present invention is as described above, even if there is dust or foreign matter inside the tube, or even if the inner wall of the tube is wet with water, oil, etc., the guide member will not close and can be effectively operated. It can move under wind pressure, and has the excellent effect of easily passing the wire connected to the guide member.

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.

Claims (1)

[Claims] A linear body is connected to a parachute-shaped guide member surrounding a sphere, the guide member is inserted into a tube, and air is blown into the tube, so that the guide member is moved by the wind pressure. A method for passing a wire through a tube, characterized in that the linear body is passed through the tube body.
