FIELD: physics.
SUBSTANCE: transported medium is emptied from the pipe. Shut-off and control equipment is removed and replaced with a dynamic emitter. A sensitive element is placed over the beginning of the pipe. Sound vibrations with resonance frequency in the range of 800-3100 Hz are generated in the pipe using the dynamic emitter. The sensitive element detects resonance frequency of the pipe in the range of 800-3100 Hz. The pipe is found by moving the sensitive element over the ground towards the side with maximum amplitude of vibrations of the ground at that resonance frequency. The layout of the pipe is determined from the presence of maxima of amplitude of vibrations of the ground at that resonance frequency.
EFFECT: simple method which provides high reliability and selectivity of determining layout of both non-metal and metal pipes.
