Cross section of tunnel with their detailing

This architectural drawing is Cross section of tunnel with their detailing. A tunnel is relatively long and narrow; the length is often much greater than twice the diameter, although similar shorter excavations can be constructed, such as cross passages between tunnels. In order to understand how a Tunnel Boring Machine works, we will divide its components into three parts: Cutting Head (front) Tunnel Field (middle) Trailing Gear (rear) The excavated area of tunnel is 58.179Sqm., over-break percentage is 12.44%. Minimum excavation area of the tunnel is 49.170 Sqm. For more details and information download the drawing file.
