Method for detecting PE tube tracing line

Abstract

The invention discloses a method for detecting a PE tube tracing line. A power source, the tracing line and an electricity measuring tool are adopted in the method. One end of the tracing line is connected with the power source, and the other end of the tracing line is connected with the electricity measuring tool. The on-off states of the tracing line are judged according to display data of the electricity measuring tool. By means of the mode, the method is easy and convenient to utilize and low in cost, the paving situation of the PE tube tracing line can be fast checked and accepted, the on-off states of the PE tube tracing line can be effectively monitored and maintained in real time, and therefore the quality and the progress of the pipeline engineering are effectively guaranteed.

Description

Technical field [0001] The present invention relates to the field of PE pipe tracer detection, in particular to a detection method of PE pipe tracer. Background technique [0002] When the newly-built gas pipeline is a PE pipeline, in order to ensure accurate detection of pipeline location information and ensure the safe operation of the gas pipeline, a tracer line needs to be laid above the pipeline. The tracer wire is a kind of conductive metal wire after the anticorrosion treatment, which is generally used for deep buried occasions. It is laid close to the pipe. Connect one end of the tracer wire to the pulse signal to be on the ground. The signal is measured remotely, and the spatial position, depth and direction of the pipeline can be determined. At present, the pipeline detector is generally used for testing and acceptance when the PE pipe is installed and the pressure detection is completed. The commonly used pipeline detector is Radiodetection. Due to the high purchase c...

Problems solved by technology

At present, the pipeline detector is generally used for testing and acceptance when the PE pipe installation and pressure inspection are completed. Now the commonly used pipeline detector is Radiodetection. Due to the high purchase cost of Radiodetection, it needs professionals to operate, and its The working principle is also to use the pulse signal to carry out road surface telemetry on the tracer line, so it is easy to be interfered by a strong magnetic field source during the test, and the actual position of the pipeline cannot be determined

Moreover, there is no effective monitoring method during the construction of PE pipelines, and real-time monitoring cannot be achieved. It is often found that the laying of the PE pipe tracer line is unqualified or even the tracer line cannot be detected during acceptance. At this time, the pipeline must be re-excavated. In order to find the position of the tracer line where the problem occurs, and the tracer line is very thin, only 1.5-2.5mm 2 , during the excavation process, as long as there is a little bit of broken bricks, tiles, and weathered stones, the tracer line will be broken, so it brings a certain degree of difficulty to the detection of the tracer line
