Description

Eptisa has installed an auscultation system to monitor the slope at 418 kilometre point of the A-6 during the stabilisation works and subsequent operational phase.

The behaviour of the slope is monitored using inclinometric pipes of up to 80 metres in length and piezometers at the different elevations of the retaining slope, load cells in the anchor points of the retaining walls and surface monitoring surveying techniques. The electrical sensors are connected to an automatic metering station. The results have been made compatible and can be consulted online using the CELOSÍA program of the Spanish Ministry of Public Works.
