Donnie the Tunnel Boring Machine, behind some people. https://www.trenchlessinternational.com/2019/12/17/boring-begins-on-coxwell-bypass-tunnel/ #Coxwell
This prufrock thing pure vaporware. Elon Musk has no experience in mechanical engineering yet alone in tunnel boring machines. You may hire some experien...this and that on a Lovat TBM. But inventing a tunnel boring machine...
The machine is Herrenknecht. But anybody know what Disc cutters they used? Also Herrenknecht?
Maybe the disc cutters were not Herrenknecht. You know how it works. First x meters you use disc cutters of the TBM manufacturer. So maybe first x meter they used Herrenknecht disc cutters and then switched to an after...- ' thanks to the Japanese engineers' contributions to tunnel boring machine technology'? Are you serious? The last time I checked it was the USA a.k.a Robbins, who invented TBM and took it further than anyone else.
We are happy as our cutters and other tools are preforming well on this project
@Paolo As far as I know, the disc cutters did a good job in Follo.
As usual, New Civil Engineer is has a more sober header than daily newspapers. Progress revealed on HS2 tunnel boring machines https://www.newcivilengineer.com/latest/progress-revealed-on-hs2-tunnel-boring-machines-27-05-2020/
Yes it is true that whenever an article has "Elon Musk" in it, the guy gets the benefit of the doubt even for radical things like 10 times faster boring tunnel boring machine...- pretty imressive. I heard that it hasn't been a smooth ride all along. I heard they had to change a lot of disc cutters along the way. Like I heard 20 disc cutter every single day had to be replaced!
