Introducing new computational techniques to model the drilling and excavation process will help operators choose the optimum drill bits and operating parameters.
Geofit is using a novel wear test and excavation modelling techniques to simulate the cutting process induced by excavation tools in order to improve the drilling hardware parameters. We are also applying horizontal directional drilling for the installation of horizontal loop heat exchangers in urban environments, which is faster and allows to keep the drilling design under control and reach longer lengths.
Ground Penetrating Radar
Compact ground penetrating radar (GPR) array and integration into GEOBIM system
Product & Service
Partner: IDS GeoRadar
Collecting information on underground assets may prevent damages during excavation. Specifically, this concerns both the data acquisition system (that implements a compact array or radar sensors) as well as the data processing software (see also ER#7) and the use of such information via a GEOBIM platform.
The use of information on underground obstacles, once integrated in the design of the retrofit, enables the selection of the most suitable area and to prevent problems during the installation.
The development of the compact GPR array is not a result of GEOFIT; however, the integrated use of the information provided by the sensor is the relevant goal in this project. This will open a further exploitation possibility for the use of this radar technology that is fully non-invasive/destructive.
The whole procedure will be tested in 2 pilot sites (Perugia and Bordeaux)
