Jet Grouting cut-off wall for the construction of the upstream cofferdam - over 30 m of water head - interpenetrated columns on 1 or 2 lines - Ø
1500÷2500 mm diameter - over 65 m depth - wall's total thickness from 0,8 to 1,6 m - extensive verify et test program - quality controls during
construction, including the continuous monitoring of Jet Grouting parameters by a real time data collecting system, the inclinometric measure of
every bore verticality, coring, permeability measure and pumping test at the end of operations - maximum permeability 1x10-6 cm/sec -
unconfined compressive strength 2 MPa at 28 days
