GPR application in Civil Engineering to search and detect underground Networks

Abstract

The industrial development and the intensive use of urban space lead to several problems in the management and operation of public services such as drinking water networks, sewer, telephone, gas, electricity, street lighting, and various cables and pipes that are buried either at footpaths or roadways. Damage or malfunction of pre-existing public services can potentially cause danger to humans. In order to minimize risks, GPR profiling was constructed as a tool of advanced non-destructive technologies leading to practical solutions to detect buried networks and reduce problems related to the destruction of existing underground utilities. The main objective of this study is to search and identify the various hidden systems to map them and indicate them on-site to avoid possible incidents. The purpose of this operation is to produce GPR profiles on the surface to be examined, while respecting a fairly regular spacing between patterns, using non-destructive techniques such as the GPR and the radio detector.
