Wow Jeff, great job catching this!!!! Best channel on "tv"!
Lovely music, too. Great stuff!
Great timing to catch this Jeff!!
Thank you!
Middle shield, articulation rams (for steering) poking out at the front, thrust rams with large shoes poking out of the back (shoes to spread the load as it pushes on the last built segmental ring). Also the ring erector sticking out of the back. Think this is a test fit to get the angle right (not as easy as on the level but quite common to have some required angle to work with (2-5% gradient).
Also can see the 4 main drive motors on the back of the cuttheread front shield. Pretty normal for this size EPB soft ground TBM.
EPB = Earth Pressure Balance? Does this suggest they expect to encounter ground water?
Or is this just the type of machine it is, and being used here because it happens to be adequate?
Bit of both. EPB is probable ideal for the ground conditions. I'm pretty sure they will be below the water table, so a pressurized face chamber is necessary.@@DessieDoolan
Thanks Jeff. Good catch!
Pity, that wind was too strong ... next time
Merci👍👍👍
Awesome
❤❤❤The videos are always interesting, but I can feel my blood pressure drop when I hear the music you use.❤❤❤
No matter the the music, there will always be someone that complains.
Thanks Jeff great coverage!
FANTASTIC VIDEO Jeff , thanks you , from Spain
My wife says she didn't know people could do that, and even though I drive heavy machinery, I was also surprised.
@DessieDoolan Yes, earth Pressure Balance, usually achieved with an Archimedes screw from the pressurized front chamber to the back of the TBM tail shield, where it discharges onto a conveyor. The length of the screw acts as a plug to dissipate the face pressure through friction as it moves up the screw. Plenty of videos on UA-cam to graphically show the EPB principle. TBC seem to have only used EPB machines to date, they can resist groundwater hydrostatic pressure up to 3-5bar (45-70psi, 30-50m depth, 100-170ft).
From the location, surface ground conditions and recent rainfall on videos I would expect they will be working below the groundwater table on this tunnel. Similar to the ones they experimented with at Bastrop.
Thanks David. Factory floor level is 418.5,' perimeter road around 412', bottom of the stormwater system is 398 (about where the tunnel will need to duck under it).
River is 390' as shown on the site plans as the OHWM (ordinary high water mark).
Site is old sand and gravel quarries, so tunneling through the water table for sure.
How much cover under the stormwater pipe? Couple of feet. Plus the TBM diameter. 10' 3.0m or more into the water table.
Ideal cover would be 1-1.5 TBM diameter. Not always possible. Can go as close as you want but with much greater risk of damage. If the sewer was designed with this crossing below it in mind it could have been locally strengthened. Either way I would want 6-10 foot between them depending on the ground conditions.@@DessieDoolan
@@tunnellingsalisbury7605 The stormwater drain is 8' 2.4m corrugated steel. Laid almost 3 years ago, so likely would pre-date any tunnel plans. It is Tesla's drain though, so the risk is theirs and no utility to ask permission of.
The obstacles between the highway and the building perimeter would be the 8' 2.4m drain, electrical ductbanks (no more than a metre deep I would think), a combined fire and domestic water supply (a blue HDPE pipe of around 12" -18" 0.3m 0.45m diameter), and 8" 0.2m sanitary sewer drain laid unusually deep.
242' 73m centre to centre of stormwater drain and sanitary sewer.
Assuming no cover, the angle is quite shallow to get under the stormwater and over the sanitary sewer. A little over 3 degrees.
Assuming 1 x TBM diameter (14' - 15' ? Tunnel is 13'6" external) cover under the stormwater drain, a little over 6 degrees.
I'm relying on the depth of this sanitary sewer and the gap in the perimeter grade beam as evidence of the tunnel entrance being inside the building by no more than a column bay or two.
My understanding of TBC's method is to dive and climb at a maximum of 15 degrees. This would shorten the distance from the undercrossing to get back to the surface. Only the drain seems an issue. Anything else can be diverted if necessary but they are also flexible enough for the TBM to pas below with some settlement without major damage/risk.
Damage is all about differential settlement, or the width to dept ratio of the settlement trough above a TBM (there always is one to some extent, I have even seen them in hard rock). Deep, small diameter tunnel, low "face loss" (effective amount of over excavation and /or lack of annulus grout) and you get a shallow wide trough, minimal impact on things above and around. Shallow, large diameter tunnel in soft ground and the trough gets deeper and less wide, potential damage to buildings, utilities etc.
It's an imprecise but well documented and understood subject in tunnelling and deep excavations. @@DessieDoolan
Directly facing the 'old well' aside the forthcoming south end extension. The well that dig too deep and broke into Giga Underworld.
I'ts a little baby TBM....
What's the purpose of the tunnel? They literally have a road under the bridge 50 meters to the right.
IMHO, I think it is intended mostly for testing and demonstration.
That's for trucks, employees, site access etc. This tunnel will be directly from end-of-line production to the delivery lot. There's a chance the cars are totally protected from the elements, but there's also a good chance they can get there totally autonomously now too.
@@Jessev741 Not big enough for semi trucks. It is barely big enough for cars.
@@jbbuzzable wut? The tunnel is for finished Model Ys and Cybertrucks, not semis... The ROAD is for trucks
I believe it is to send cars from the factory to the outbound lot. Then as cars are manufactured send them through the tunnel directly to the outbound lot. I am surprised they are doing this at all as you say there is a road they could easily have used. Maybe just one of musks eccentric ideas. Or maybe they see no point in driving under the bridge to the south, especially as they ramp up production, one strange thing to me is that it looks possibly like the factory side of the tunnel will have a lift to get cars into the tunnel, I would have thought that would be a bottleneck when production ramps up. Also the tunnel does not look big enough for a cybertruck so will they be driving cybertrucks under the bridge? Strange but very interesting and something that will make interesting viewing I am sure.
😍😍
Seems small?????
Wouldn't one pre mounted flat deck work as a launch platform?
Definitely needs work on the launch platform setup if they are to bore Pedestrian walkways, Animal crossings, Culverts, Cattle crossings under Road/Railways.
Pipe Jacking would probably work best for those smaller tunnels though?
Doing the Lords work to increase the harvest. Revelation 6:15
Pipe jacking gets less practical above about 10 foot diameter (pipe transport and handling), but it can be done (cast on-site etc). At this location I would have recommended a box jack solution. But TBC don't have that technology so EPB TBM it is. I'm sure it will work.
This is going to be really interesting, seeing how they bore the tunnel, a pity we could not have a camera or cameraman on the ground showing what is happening, we will just have to hope one of the drones captures footage of the initial drilling during the short times they fly over the site. I wonder if a camera could not be set up just of the side of the freeway showing live footage over the time it takes to drill. A simple tripod secured to the ground with a camera on it and a small solar panel to power it. Yeah big dreams.
Pretty common to do this. Timelapse footage of TBM's working is all over UA-cam. I have hours of it from my own projects. Maybe TBC will do it here to showcase their technology.
