Excavations – access tunnel and east precut for the Považský Chlmec tunnel
The Považský Chlmec tunnel is part of the D3 motorway northwest of the city of Žilina. During preparations for tunnel driving, two precuts (west and east) and an excavation for the access tunnel in the middle of the tunnel were made. The 20-metre-high east precut was stabilised with shotcrete and soil nailing, and anchors were installed as necessary. Pit lining with soil nailing and soldier pile walls was used for the access tunnel excavation.
