ULTRASONIC BASED DEFECT CHARACTERIZATION IN WASTEWATER CONCRETE PIPELINES USING INVARIANCE TRANSFORMATION TECHNIQUES
This paper focuses on the development of an innovative nondestructive test procedure (system + algorithm) for characterizing defects in concrete sewer pipelines, using ultrasonic inspection. A signal processing technique is being developed that is invariant to changes in both concrete material properties and composition of wastewater. Results to date from earlier research projects have indicated that such algorithms can be designed for characterizing defects in pipeline steel of varying material properties or operational parameters. Development of such an inspection procedure will be the first step in the design of a mobile autonomous vehicle for inspecting wastewater pipeline systems. Preliminary research results are presented in this paper.
