Tunneling Works :
Tunneling is the best solution to overcome problems of
Open cut excavation in the crowded and heavy traffic areas and also deal with lots
of underground utilities. Tunneling designed to work in deep areas below
the underground water level to avoid the risk of dewatering which affects
the surrounding buildings.
All tunneling activities are controlled automatically from the control unit beside
the cutting head or the cabinet on top of the ground level. The ( AC-Tunnels
and Slip Forms Department ) has Tunneling & Micro-tunneling machines
500, 600, 700, 1000, 1200, 1500, 1800, 2200, 2500 and 3200 mm diameter,
which was used successfully in several projects all over Egypt.
