Buried pipe assessments (condition assessment and material identification) based on stress wave propagation
12 Dec 2024
Abstract
A nondestructive evaluation method for determining the material used in a below-ground service line includes inserting a probe with a wave measurement device therein into an area corresponding to a location of a service line; generating a service line wave through an exposed portion of the service line using a vibratory shaker or other mechanical excitation; measuring, by the wave measurement device, a substrate wave created by the service line wave passing thought the service line and into the substrate; identifying, by a data acquisition system, the service line wave velocity and attenuation; comparing the service line wave velocity and attenuation to a known set of wave velocities and attenuations in service lines according to a service line material; and identifying the service line material in the service line by comparing the wave velocity and attenuation in the service line with the known set of wave velocities and attenuations.
