The double track railway line that will connect Nykirke – Barkåker is taking shape!
The first section of sheet pile has been successfully installed in a sensitive clay for excavation works of Kopstad Tunnel (Nykirke – Barkåker).
The temporary supporting structures solution consists of steel sheet piles with multiple anchor levels. To activate the required passive resistance the sheet pile toe will be fixed at the bedrock level by rock bolts (commonly used in European Nordic countries).
Deep soil mixing is also expected in nearby areas of the tunnel to improve the clay response.
