HS2是最先進(jìn)的高速鐵路，對(duì)英國的低碳交通未來至關(guān)重要。它將提供全國急需的鐵路運(yùn)輸能力，并且是北部和中部地區(qū)鐵路項(xiàng)目不可或缺的部分。海瑞克制造的TBM長170米，每個(gè)重約2,000噸。 每個(gè)刀盤的直徑為10.26米。 列車將通過的隧道的內(nèi)徑為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.”
