Dude this is the best stuff I’ve ever watched. Ming boggling sophistication, these guys deserve to be celebrities instead of the fools so many idolize for offering nothing to humanity 😊
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!
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...
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 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.
Your channels got shared on one of the engineering pages on Reddit recently and I'm loving all these videos! I wish more companies were willing to show off like this.
Impressive! Impressive work, impressive technology and impressive presentation! It's like a documentary that goes straight to the point without wasting time in nonsense details and stories that have no relevance for the subject.
Outstanding rail and tunnel construction! Here in Australia we have politicians that are so corrupt that any construction like this would cost at least double of what it would cost in Europe!
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!
I love these videos, you guys are amazing in what you do and how you do it but these videos should get an award!!! I want a Marti t-shirt with the TBM!!!
I just love to watch this stuff. I wish this was the norm for broadcast TV ... something to stimulate peoples' brains. This is cool! Fantastic animations.
Truly enjoyed watching this video! The video animation presents the construction works so detailed and easy understanding. Kudos to the producer and also Marti Group for the successful and amazing construction work!
Magnificent! I'm impressed of the engineering, vision, creativity, and imagination to develop processes, procedures, machines, mechanisms, and all the tools, knowledge, experience, and skills to do something like this. I really enjoyed this video.
These videos are really good, I watched one and was like oh this is by the company that did it wow thats a lot of effort to share something so cool, these videos are amazingly well made thankyou.
I thought I was watching National Geographic and then thought ot myself… oh they really improved their animations lately, then i looked at the channel name and saw it was a company, thats amazing, why dont more companies do this, its such good marketing and gives the population a good idea of how the projects around them are built and makes us appreciate such work everytime we take a train through the tunnel
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.
Can't get over how California frets and baulks at putting in a single high speed reai line like it's an impossible expense yet Switzerland does dozens of these projects and does not bat an eye.
It's just how economies of scale work, if you are constantly doing something the cost per unit will drop substantially and ease of the project increase.
This is great stuff. These monster tunnel projects fascinate me. This ranks up there with the Gotthard Base Tunnel and DC Water's massive sewer-and-storm-drain-separation work.
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 🙏
@@SMGJohn Yet it takes tiny Switzerland to advance all these engineering technologies together to another level of perfection of scale, extent and complexity. They overtook the British and the French as far back as 1871, starting off with the old Gotthard Tunnel , right up to this day. ruclips.net/video/6AV2NcyX7pk/видео.html ruclips.net/video/TaYtrsvzfh0/видео.html etc., etc...
@@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.
@@SMGJohn O dear me, how patronizing that you deem it necessary to tell me *that much* about the historical perspective on tunneling. I'd never have known otherwise that the 1871 Gotthard Tunnel was not bored by a mechanical worm.
18:03 A wonder construction was possible in such a chaotic environment. People are even driving backwards there. But actually beautiful video with unmatched, easy to understand detail.
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.
We need this sort of tunneling in del mar California we have a single track mainline on a cliff thats falling into the sea thats both a choke point and dangerous.
Great and complex engineering! But at this point I was wondering, wouldn't have it been cheaper to just build the additional lines above ground using occupied land and compansate the homeowners?
Are Marti building their own TBMs by now or is it Herrenknecht stuff? The hydroshield sounds pretty Herrenknecht to me. Awesome video, Hopp Schwyz! Edit: Und ist der Berg auch noch so klein, muss mindestens ein Tunnel rein! :D
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.
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?
Other companies: Make CGI of products not yet built which have a high chance of becoming vapour ware. Marti: Makes CGI education videos of projects they've already done.
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.
Thats how you do a freaking add video!!! Why aren t these on discovery channel already? We need more of these. Please, the next one, do a tunnel under the moon. I bet you can do it!!!
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.
It's like watching National Geographic. Really high quality videos.

Very detailed and elaborate video explaining intricacies of construction methods. Well done marti group!
Never in my life I thought I'd be fascinated by tunnel boring machines and how they work. So impressive!
It's one the best documentary videos I've ever seen
