\n

In the valley of Martigny, a small town in the Valais canton (Switzerland), underground works for the installation of 380 kV high voltage lines between Biatiaz and Verney are ongoing.<\/p>\n

ICOP<\/strong>, by means of its swiss branch ISP CONSTRUCTION, executes the IN\/OUT microtunnelling shafts using 1.5m thickness diaphragm wall and 1500mm diameter jet-grouting technique, under presence of high voltage overhead lines.<\/p>\n

The shafts have a rectangular geometry, 17m x 10m and 26,50m depth for the IN shaft, 12m x 7,50m and 21,50m depth for the OUT shaft.<\/p>\n

As the watertable is at 1.5m from the working platform, jet-grouting was used to install bottom slab and IN\/OUT MTBM for both shafts.<\/p>\n

ICOP<\/strong> realizes its tasks for the Consortium VERTIAZ (CSC<\/strong> and WEBUILD<\/strong>), under the supervision of SWISSGRID.<\/strong><\/p>\n<\/div><\/section><\/p><\/div>\n
