Abstract

The invention discloses an underground pipeline detection method and device. The method comprises the following steps that 1) an emission antenna sends high-frequency pulse electromagnetic waves in certain intermediate frequency to an underground medium, and the electromagnetic waves are reflected to the ground when encountering a detection target; 2) the electromagnetic waves are received by a reception antenna; 3) electromagnetic wave information collected by the reception antenna is conveyed to an information processing module, the information processing module analyzes the waveform of thereceived reflection waves, positive and negative peaks of the waveform are represented by black / white or gray scales or colors respectively, and a target pipeline is located; and 4) a result detectedby the information processing module finally is displayed by an image display module. The underground pipeline detection device can detect metal / non-metal pipelines, the application range is wide, theheat radiation efficiency of the pipeline detection device is improved, normal use of the pipeline detection device is ensured, and the service life of the pipeline detection device is prlonged.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to an underground pipeline detection method and device. Background technique [0002] Underground pipelines are an important infrastructure of cities. In recent years, with the development of urban construction, the transportation system, energy system, communication, information network, etc. have been vigorously developed, such as railways, subways, light rails, power supply, heat supply, gas supply, etc. The implementation of various projects is inseparable from the underground For various reasons, pipelines are an important hidden infrastructure. Due to various reasons, pipeline information is incomplete, and some of them are inconsistent with the status quo. Moreover, various pipeline rights belong to different departments, and insufficient attention is paid to pipeline management. This increases the difficulty of pipeline management. In the middle of the world, the...
