Eppenberg SBB Railway Tunnel - From installation to the breakthrough

The Eppenberg is one of the traffic bottlenecks in the Swiss railway network. The consortium ARGE Marti Eppenberg, under the direction of Marti Tunnel, is building the approximately 2.6 km long #tunnel. For more than 2.5 years, Marti Solothurn and Marti Zürich have been working on the portal areas with extensive special civil engineering and concrete work. The efficient and powerful infrastructure of the installation sites is the central part for a successful realization. Additionally, the tunnel boring machine had to be rebuilt in the underground, it was converted to a so-called #hydroshield.

[@StanislavG.]

Not sure what impresses me more - Marti's outstanding engineering and awesome videos or the awe inspiring way the Swiss government is investing in people by investing in public transportation. Good job all around!

[@petlahk4119]

I really wish the US government would go back to doing large public works projects with good planning and efficiency. Instead of trains and stuff we get the globally infamous Texas Katy Freeway...

[@reinmarandi6174]

Yeah.. Marti sure seems like standup guy. Engineering the whole of the project all by himself.

[@Peter-jl4ki]

Rail tunnels are cheaper by orders of magnitude than car tunnels with equal capacities. Building rails certainly counts as investing if the alternative is LA style congestion, or just letting the infrastructure rot. But if the goal is to improve car traffic, getting a couple of people in cars off the road and into trains, trams, and buses is the most frugal, cheapest possible way known to man to improve congestion on roads. Which is a good thing to be sure - only ideologues and corrupt oligarchs wouldn't build both public transport and roads as a combined solution for traffic.

[@ADRIAN-zh4ti]

@@petlahk4119 America is huge. Switzerland is tiny. Not the same budget to maintain public transportation.

[@burkino7046]

​@@ADRIAN-zh4ti Yea America has a lot more budget, they could easily do it if the car industry didn't heavily lobby against it. We'll spend billions more on infrastructure that has a way higher maintenance cost, way shorter lifespan, and way less efficient.

It appears that they have taken lesson from Russia, where all projects take double the actual cost and double the time to build ... so there is enough money to 'grease' all the wheels of power!

​@@SMGJohn Yet it takes tiny Switzerland to advance all these engineering technologies together to another level of perfection of scale, extent and complexity.

@@benedictdesilva6677 They did not tunnel those old ones with TBM I can tell you that much. And we see again that modern TBM's still operate the same as they did when they were invented, they require immense amount of manpower to operate, and I really do not see what the Swiss has "accomplished" here, the next revolution in TBM are to make them require as little workforce as possible in order to tunnel for longer time with as little downtime as possible such as switching out cutters while under operation, something only experimental machines are doing today.

[@benedictdesilva6677]

[@vinnyjhawer7847]

Its amazing how this machine digs the tunnel and makes the supporting walls too. Thats one smart invention. What the Victorians would of done with that machine, they certainly wouldn't have had as many deaths. But those who died are the pioneers and this wouldn't have been possible without their sacrifice. RIP 🙏

[@44R0Ndin]

Another thing I noticed, these ring segments are using both steel reinforcement AND additional fiber reinforcement (almost certainly just plain fiberglass, but it could be aramaid fiber or carbon fiber, if the mechanical properties are extremely critical, but those last two options are usually prohibitively expensive). Must be nice being able to just drill a tunnel where you want it to go, I'm over here in New York state and... well all our mountains are "rubble piles" formed during the last ice age by the glaciers pushing around rocks of any size from sediment to house-sized. Heck, the most solid rock we have around here is Shale, and even that's just begging to erode given the smallest flow of water, since it's just weak sedimentary rock. We do have a few tunnels around here, but it's very much not a common thing.

Would it be feasible to freeze the loose and wet soil in front of TBM. If soil becomes solid from freezing and can be removed like rock, it would save time. No need to modify cutting wheel, no need for Bentonite, no need for pumping, separation, re-using of Bentonite. When they were building Grand Coulee Dam, there was a soil condition causing slumps while excavating. They used either chilled salt water or Ammonia as the refrigerant. They froze large areas so excavation could continue.

November 2022,.....in my community in the USA, in Columbus, Ohio,....a large bore tunnel machine is being employed, to dig a tunnel from the North end of Columbus to the South end,...it will be, ( not sure if the whole tunnel will be used) for clean and waste water transport. Like I don't know if the whole tunnel will contain multiple large pipes, ( I am guessing it will), to provide this water movement. The project will go on for several years. Only recently in the summer of 2022, in a city owned public park, less than a 1/2 mile from my house, is where they are staging the first part. Tuttle Park is it's name, and it is a 1/2 mile north of The Ohio State University, campus. We were informed it will be dug in sections, which will later, meet up. It is not clear if the tunnel will run under the entire city Columbus. But the earliest sections, are meant to improve the waste water and fresh water transfers in many communities where old, underground water pipes, have not been improved in at least 100 years. We were informed that was may hear strange noises coming from the dig, which is quite deep in the ground. These machines can operate 24 hours a day.

[@DraconicKobold]

Belt that comes from a belt storage is understandable but how did the pipes get longer while drilling is going on? (12:33)

[@rogervondach1238]

Am I missing something? I heard the same thing over and over and not just in this video. They always say "underground tunnel", why? Has anybody ever seen an above ground tunnel?
