Grease was injected into wire brushes and the mm 4 in space between the metallic brushes and the tunnel lining. Grout lines were fitted into the tail shield allowing fine cement grout to be injected into the mm 6 in annulus between the tunnel lining and the ground. This method sealed the tunnel lining as the TBMs advanced. In spite of the difficult conditions, advance rates improved throughout the boring with the Robbins service tunnel machine averaging m 2, ft per month for the project.
The U. Unforeseen water inflows in a 3. After passing through this section of tunnel, the machines experienced no further difficulties and began averaging m ft a week. The Robbins machines on the U. Muck transport on both sides of the tunnel was complicated but worked well. In the U. The conveyor then dumped the muck into lagoons behind sea walls in the English Channel. In all, about 4 million m3 5. The area, called Samphire Hoe, is now a popular park.
On the French side muck was crushed and mixed with water in a chamber at the bottom of the Sangette access shaft. It was then pumped up the shaft and behind a Diplomacy was critical to the success of the process. In present day multi-country projects involving shared resources and infrastructure, should diplomacy play a stronger role?

Education and Innovation: The Channel Tunnel has set an example worth following.
China is building maglev trains in partially-vacuumed tubes. France has long been a leader in TGV. Japan opened a new era with Shinkansen. Should the world consider an International Rail Institute Service Corps where engineers, designers, and chefs, could cooperate to produce the fastest — and most entertaining — rail transport of the future?
