Description:

S.E.A expert acquisition system with Optical Strands, Temperature probe

Triple drilling perpendicular to the railway tracks,with a diameter of 60 cm, was required to a depth of 2 metres in such a way as to not impact the functioning of the railway line during the operations. The client wished to ensure the stability of the tracks during the work to avoid any differential between the tracks or any longitudinal settlement caused by subsidence. The 365 dynamic loads recorded, that correspond to the railway convoys, caused stable and identical amplitude deformations during the work, proving that the drilling did not cause any subsidence.
