Brilliant technologie. In years 2014-15 i worked in Aichelberg in Germany,and have a very good lifetime experience when i watched this machine live at the tunnel begginning point. I worked in the fabric for the tunnelling technologies. I learned so many here for example,the railways installation as a system for producing the stones for tunnel. We are here a very good international team from Slovakia,Hungary,Poland,Austria,Germany,Russia,Ukraine,Italy,Turkey....
I thought I was getting recommended this because I've been watching Scrap Mechanic (videogame) videos. Now I'm not sure. In any case, I was surprised at how much of this I understood based on my amateur knowledge of geology and mining.
Cutting tools do not play a role in the balance of forces. Once the rotation of the cutting wheel is stopped, and the cutting wheel retracted from the excavation face, the cutting tools can be changed from behind the cutting wheel. This intervention is carried out by an operator. Best regards. Herrenknecht AG
So the tunnel relies on the ground pushing it inward to keep it together? What if there's an earthquake and pulled the ground and tunnel apart then water leak inside the tunnel?
Earthquakes liquify the ground, not necessarily pull apart the ground. It would be more like the tunnel is suddenly inside a soup of sediment, so to speak.
You also did not know how to start your tunnel project, since you don't have a starter point, nor do you know how to get a starter shaft. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HCDsFIqIfA0.html&ab_channel=HerrenknechtAG Your welcome.
Kleine Tunnelinnendurchmesser für Tübbingausbau sind u.a. nach einer individuellen Projektrisikobeurteilung zu bestimmen. Die DAUB (Deutscher Ausschuss für unterirdisches Bauen e. V.) empfiehlt einen Innendurchmesser von mindestens 3.500 mm, um den Sicherheitsrichtlinien bezüglich Fluchtwegbreite, Fluchtkammer auf der Tunnelbohrmaschine etc. gerecht zu werden. Technisch möglich und in der Vergangenheit bereits umgesetzt wurden von Herrenknecht Maschinen für Tübbinginnendurchmesser von 2.000 mm.
Good afternoon, the TBM usually arrives in a shaft where it is disassembled. Then all components are again lifted to the surface. In other cases, when facing space constraints, some TBM parts or even the complete machine has to be retracted back through the same tunnel until the start shaft. Best regards. Herrenknecht AG
And when they're done a lot of these machines are just turn to the side and buried in a dead-end tunnel! It's not worth taking it apart and sometimes they're pretty worn out by then. Or do they? Graft a Surplus nuclear submarine on the end of it and go where you want
Good afternoon. The geology along the tunnel project is usually thoroughly analyzed and drilling campaigns are undertaken before the project starts. This enables to evaluate any potential danger. The cavities are one of them amongst other like water pressure, gases, rock abrasiveness, and so on. Then TBMs are designed according to the properties of the geologies they could encounter. Best regards, Herrenknecht AG
@@HerrenknechtAG good answer, I guess you could pump concrete into any void ahead of you, you Germans are pretty smart (I married one from Dresden I know) thanks.
