Problems solved by technology

These two types of instruments are detected by means of electromagnetic and radio, and they have the following common disadvantages: (1) the detection depth is limited; especially for the detection of cross-river pipelines, there are difficulties; (2) the metal shielding on the pipeline cannot Detection; (3) Strong interference from on-site electromagnetic field; (4) Complicated operation steps, slow measurement speed and low efficiency
However, the type of data collected by this probe is single and the detection range is small; Chinese patent CN205120128U discloses a three-dimensional attitude measuring instrument for pipelines based on inertial measurement technology. The steel cable winch on the side realizes the movement of the measuring instrument in the pipeline, but the measuring instrument still needs to penetrate the steel cable through the pipeline before the measurement, and there are certain safety hazards for the old pipeline in disrepair during the penetration process

Description

technical field [0001] The invention belongs to the field of underground pipeline measurement, in particular to an underground pipeline direction measurement device and a use method thereof. Background technique [0002] Underground pipelines are becoming more and more dense, and many pipelines need to be maintained, diagnosed and repaired; accurate information on pipelines needs to be exchanged between various pipeline departments during the construction process. However, due to historical reasons and poor management, the underground pipeline network that has been built in the past cannot provide accurate pipeline location maps. [0003] At present, the mainstream measuring instruments for detecting the position of underground pipelines on the market include electromagnetic pipeline detectors, ground penetrating radar, etc. The former uses the principle of electromagnetic induction to detect metal pipelines, electric / optical cables, and some non-metallic pipelines with met...
