Eppenberg SBB Railway Tunnel - From installation to the breakthrough

[@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.

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.

Why is this so Goddamn interesting. Its a freaking tunnel!

[@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.

[@SJR_Media_Group]

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.

[@kristinaF54]

The tunnel was estimated to be completed in 2019 and it's now 2023, so I wonder how it went? Wish there was a prologue video showing what it looks like now in February, 2023.

[@44R0Ndin]

It's mentioned that the upper portion of the concrete lining of the tunnel is supported by gravel, yet while you're excavating the tunnel, a great deal of crushed rock is produced. This seems like an opportunity to make use of material that would otherwise go to waste and need disposal. So I wonder if this project exported some or all of the crushed rock produced by advancing the tunnel to a rock crushing plant, where it would be processed into gravel suitable for use as that back-fill gravel that was mentioned. After all, if it's stable rock that you're drilling thru, and you need gravel, it makes sense that the existing rock would provide good material for that purpose, would it not? Now, I don't have a civil engineering degree, so it's entirely possible I'm way off base, but I did get a 95% on my high school physics class, and I also took a couple CAD drafting classes in high school. I have not gone to college to get a degree, but I don't think it takes an expert to figure out that reusing the material that you're already producing (provided that it is suitable for such use) should lower costs, right? EDIT: The answer to my question was further along in the video, apparently I had a good gut instinct after all.
