Сontactless Ground Penetrating Radar solution for tunnel inspection
The ground-penetrating radar system (GPR) Stream T measures tunnel anomalies such as lining thickness, reinforced structures, cavities and wet areas. Stream T's modular structure allows this innovative GPR array to overcome obstacles and increase productivity fivefold compared to traditional systems, collecting data at up to 60 km/h (37.3 mph). The operation of Stream T from inside a vehicle increases safety of technicians at the tunnel site. Stream T's contactless antenna solution can work up to 20 centimetres from the tunnel surface, reaching a faster acquisition speed and therefore easier data collection in this difficult environment and increasing data quality as a result.
Stream T is supplied in two different configurations to meet the inspection and construction site requirements. Both deep and shallow frequencies are available. The high-quality tomography produced by the array system significantly improves data interpretation.
"Utility and services companies benefit from Stream T's faster acquisition speed and easier data collection, especially considering the substantial costs of closing a carriageway," explains Gianluca Paesanti, GPR Product Manager at IDS GeoRadar.
