Problems solved by technology

[0002] At present, the detection technology of metal pipelines in the world has become mature, but the detection of non-metal pipelines is still a technical problem. The current detection methods of buried non-metal pipelines mainly include: one is to pre-embed metal marks on non-metal pipelines The other is to put probes inside the non-metallic pipelines, and use the principle of electromagnetic induction to detect these pre-embedded metal marking lines or probes, so

Abstract

The invention discloses a method and system for directly conducting remote detection on nonmetal pipelines, and belongs to the field of pipeline detection. The principle of the Doppler effect is applied, the pipeline detection technology of the brazing method, the two-point connecting method and the exclusive method are creatively adopted, the buried pipeline depth detection technology is also creatively adopted, the underground, underwater and overhead nonmetal pipelines can be accurately, rapidly and conveniently detected, and the method and system are particularly suitable for detecting the nonmetal pipelines such as buried PE pipes and cement pipes, and solve the problem that the nonmetal pipelines are hard to detect in the world at present. According to the three detection technologies, no connecting points on the pipelines need to be found, the problem that connecting points on the pipelines are hard to find through a traditional direct connecting method is solved, the detection range is greatly enlarged, and the target pipelines can be remotely and continuously tracked and detected.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection, in particular to a method for direct long-distance detection of non-metallic pipelines. Created a non-metallic detection technology and principle, greatly improving the detection range, and can continuously track the detection target pipeline from a long distance. Background technique [0002] At present, the detection technology of metal pipelines in the world has become mature, but the detection of non-metal pipelines is still a technical problem. The current detection methods of buried non-metal pipelines mainly include: one is to pre-embed metal marks on non-metal pipelines The other is to put probes inside the non-metallic pipelines, and use the principle of electromagnetic induction to detect these pre-embedded metal marking lines or probes, so as to detect non-metallic pipelines. In the final analysis, it is still to detect metal markings, not Direct detection of non-metallic p...
