An essential characteristic of this stretch is that it has been built under the water table by excavating in very heterogeneous soils, composed of granular soils and rocks of considerable resistance which has created numerous problems during the construction ...

The inspection of the waste chips has consisted not only in the weight in the belt but also in the size and shape of the waste. Finally, the drilling parameters controlled were: - rate of advance - time of excavation - weight of material in the belt - thrust ...
