Holy fucking shit. I searched how tunnel boring machines work for fun and I had no idea how fucking complex they really are. It’s crazy that they were invented at all.

Mind blowing engineering 🤯 and they still have people who doubt we ever been to the moon and back and what's even more crazier than that is a US submarine probably is twice the complex of engineering to build than this TBM plus All the cost we certainly can accomplish extremely great things glad to be alive to witness it all like getting to watch the starships take flight is all history in the making 👍👍

What about the earth pressure balance during cutter blade change process? Maybe it can be done at safer areas with harder soil then only and is rarely needed with soft soil. Can this drive under sandy river or lake bottom?

I work as a mechanic on one of these machines. If the ground is stable enough, you can simply open the bulkheads leading to the excavation chamber and cutterhead from behind, and do it that way. If the ground is unstable, the machine comes with man-locks (essentially a series of air locks) that allow men to enter the chamber while it is still under pressure, sort of like saturation diving.

You don't need a 12 metre tunnel for metro trains. 3.5 metres to about 4 metres is fine. That means the risk of subsidence is drastically reduced.

For Barcelona it was necessary since they have the metro tracks stacked so they can use only one TBM. Using two of them would've caused massive disruptions in the city center.

I work as a mechanic one one of these machines. It navigates by using a series of lasers and prisms placed at various points along the machine and in the tunnel behind it. By doing so, the machine is able to constantly be aware of it's position in 3 dimensions. The entire route of the tunnel is pre-planned, and the machine uses the lasers to compare the machines current position and trajectory, with the pre-planned route, then presents the current deviation from the route to the operator, who can steer the machine by adjusting the pressure of the hydraulic ram groups. The operator can also use a second set of cylinders to make minor adjustments to the angle of the cutter head.
