rail tunnels is a piston relief duct, necessary to manage pressure
changes due to the movement of trains
Construction ：
• Precast segmental linings in the main TBM drives were used, but different solutions were used on the English and French sides.
Advantages:
✓ Tunneling will generate soil that has been excavated[ˈekskəˌveɪtid] and this can be used to create new land, as was done with the soil of the Channel Tunnel.

>> The Channel Tunnel also referred to as the Chunnel is a 50.5kilometre undersea rail tunnel linking Folkestone in the United Kingdom with Calais in northern France beneath the English Channel at the Strait of Dover.
