It is essential that any tunnel project starts with a comprehensive investigation of ground conditions. In addition, encountering unforeseen ground conditions, objects or anomalies can be costly in terms of time and materials. The TISA 3D Borehole Radar technique continuously gathers detailed information about obstacles and geological transition zones.
Applications TISA 3D in tunnel track exploration
TISA 3D is positioned in a horizontal borehole with a diameter of about 20 centimeters, and drilled along the planned trajectory. It measures the complete surroundings of the borehole. Rotating 360°, it gathers and processes data from all angles with special proprietary software. After processing, the raw ground penetrating radar data is combined with simultaneously collected positioning data, providing meaningful operating data.
