The design and instrumentation of an experimental rig to investigate acoustic methods for the detection and location of underground piping systems
The design and instrumentation of an experimental rig to investigate acoustic methods for the detection and location of underground piping systems
A major UK initiative, entitled ‘Mapping the Underworld’, is seeking to improve our capability of locating buried utility service infrastructure without resorting to extensive excavations. One of the four projects aims to develop and prove the efficacy of a multi-sensor device for remote buried utility service detection, location and, where possible, identification. An essential technology to be combined into the device is low-frequency acoustics, and suitable techniques for detecting buried infrastructure, in particular buried plastic water pipes, have been proposed. In order to develop and test these techniques, an experimental rig has been built. It is the design and instrumentation of this rig along with the rationale for the chosen design which is the main focus of this paper. Preliminary measurements have been made on the rig, to determine the most appropriate acoustic excitation method and to confirm that the rig is behaving as anticipated. The results of these investigations are also reported.

Abstract
A major UK initiative, entitled ‘Mapping the Underworld’, is seeking to improve our capability of locating buried utility service infrastructure without resorting to extensive excavations. One of the four projects aims to develop and prove the efficacy of a multi-sensor device for remote buried utility service detection, location and, where possible, identification. An essential technology to be combined into the device is low-frequency acoustics, and suitable techniques for detecting buried infrastructure, in particular buried plastic water pipes, have been proposed. In order to develop and test these techniques, an experimental rig has been built. It is the design and instrumentation of this rig along with the rationale for the chosen design which is the main focus of this paper. Preliminary measurements have been made on the rig, to determine the most appropriate acoustic excitation method and to confirm that the rig is behaving as anticipated. The results of these investigations are also reported.
