The project is divided in six parts with different focuses. Every joint research partner is working on an own subject.
Solites reveals a better understanding of the grouting process inside the borehole and how the quality of the backfilling of the boreholes after inserting the probes can be improved. For this purpose, the effects of pressure and filtration on the composition of the backfilling material und the formation of holes inside the backfilling are examined in real scale experiments.
Furthermore, it is investigated whether using a vibrator which is often used for concrete leads to an improved backfilling quality.
On basis of a better knowledge about the processes inside the borehole and of the experimental data, first simulations about the backfilling and hardening of the grouting material shall be carried out.
