Resumo

When the presence of buried hydraulic pipes should be identified, noninvasive methods are of particular relevance because they allow infrastructure rehabilitation for less expensive investigations than traditional methods (excavations, boreholes, etc.). The objective of this study was to identify, through a case study, existing buried hydraulic pipes at the Crawford Water Treatment Station in the municipality of Curvelo, MG for infrastructure rehabilitation. Ground penetrating radar equipment was used at the station Crawford, covering an area of 20 m² where longitudinal and transverse profiles spaced 1 m apart were studied to collect data. The presence of DEFOFO and Ocher PVC hydraulic pipes with different diameters could be identified based on the relationship between the characteristics of the existing pipe and the propagation speeds of the electromagnetic signal through the hyperbolas identified in radargrams. Additionally, the path of buried hydraulic pipes could be defined, which demonstrated the effectiveness of the Ground penetrating radar method for identifying and characterizing buried hydraulic pipes for infrastructure rehabilitation.
