Awesome animation! Just watched a documentary on the English Channel Tunnel construction and was curious on how TBMs worked.

Does Home Depot carry this? The drill bit better last the full 90 days otherwise it's getting returned!

No one can complain about this video. You literally knew what you were getting yourself into when it literally says “boring” in the title 😏

I'm looking at purchasing one of these, do you have a quote? And do I have to include the concrete walls part or is that a part of the package

Who is moving the concrete segments onto the erector arm? Seems like they just magically float by themselves without any assistance.

i have been looking for answer of tunnel boring machine, how long does it takes to boring tunnel for one kilometer ?
@chrismcquade4424 9 years ago

if this machine gets stuck/jammed is there a process to reverse the machine, or can it only be retrieved at the other end of the tunnel?
