HS2是最先进的高速铁路，对英国的低碳交通未来至关重要。它将提供全国急需的铁路运输能力，并且是北部和中部地区铁路项目不可或缺的部分。海瑞克制造的TBM长170米，每个重约2,000吨。 每个刀盘的直径为10.26米。 列车将通过的隧道的内径为9.1米。

Herrenknecht nears completion of first HS2 boring machines

 
HS2 has released the first images of its new Herrenknecht tunnel boring machines (TBM) that will help construct the new high-speed rail line.

HS2 is a new high-speed railway linking London, the Midlands and the north, serving more than 25 stations across eight of Britain’s largest cities.

This week, the first images of two TBMs were released with the machines to run non-stop for 3.5 years until the required tunnelling works are complete.
 

Constructed in Germany by Herrenknecht, the TBMs are 170 m in length, weigh approximately 2,000 t and will tunnel up to 80 m below the surface.

The machines will have a 10.26 m cutterhead, while the internal diameter of the tunnels the trains will pass through will be 9.1 m and lined with concrete segments weighing 8.5 t.

HS2 Chief Executive Mark Thurston said the project’s construction was an amazing opportunity to showcase the infrastructure capabilities.

“The TBMs are one of the most fascinating aspects,” he said.

“Like mini cities, they will spend 24 hours a day, seven days a week boring under the Chilterns so that the homes and habitats above remain undisturbed.”
