Each
section of the tunnel weighs 30,000 tonnes - over six times
the weight of the Royal Navy frigate HMS Chatham. |
|
| |
The
tunnel needed 100,000 cubic metres of concrete weighing
250,000 tonnes and requiring 20,000 truck loads to deliver.
|
|
| |
The
1,500 miles of steel bars used to reinforce the concrete,
if laid end to end, would stretch from Chatham to Moscow.
