Connecting Apparatus with Warning Sheet for Exploring Pipeline}

The present invention relates to a warning sheet connecting device for pipe detection, and more particularly to a pipe detection warning sheet connection for electrically interconnecting a detection type warning sheet with a conductive wire that provides information of the pipe during the detection of the pipe. Relates to a device.

In general, when excavating the upper part of the place where buried items such as communication cable, gas pipe and water pipe are buried, a warning type warning sheet is buried between the buried material and the ground surface in order to be found before the buried material before excavation. This prevents the buried material from being damaged by excavation.

On the other hand, if the buried buried underground is metal, it was possible to detect the ground buried detector from the ground.

However, in the case of metal underground buried material, the accuracy of reception on the ground is often inferior because the signal generated from the buried material is unstable such that the signal such as noise is mixed and the signal disappears as it reaches the receiver of the ground. .

Moreover, when the buried material was made of non-metallic material, it could not be detected through the detector. To solve this problem, a conductive medium is embedded in the detection type warning sheet, so that detection can be made more clearly and regardless of the material of the buried material.

Conventional pipeline detection warning sheet is made of a synthetic resin such as polyethylene as a raw material in the form of a film, a warning statement is printed on one side, the top of the printing layer is coated.

In general, the detection type warning sheet has a principle of 30cm or more from the coronal part, and the supervisor determines the proper position according to the site conditions.

In this way, a conductive medium is embedded in the detection type warning sheet provided between the surface and the underground pipe line, so that the conductive medium embedded in the detection type warning sheet when detecting from the ground through the transceiver is installed. It is responsible for sending and receiving signals with the transceiver.

In the case of installing the detection type warning sheet, the overlapping, wrinkling and breaking of the warning sheet should be made so that smooth transmission and reception may be performed when the pipe detection is performed on the ground.

Thus, when the warning sheet and the warning sheet must be connected to each other through the overlapping of at least 30cm at least at both ends of the warning sheet to ensure that the warning sheet does not break and achieve continuity.

However, this was not well observed during the construction process, and the connection part of the warning sheet occurred when the ground subsided in the landfill state. As such, the warning sheet loses its continuity, causing problems in detecting the pipeline.

In addition, there was an inconvenience of using a separate wire in order to directly connect the transmitter located on the ground and the conductive medium buried underground in detecting the pipeline.
