This was in my recommended, I dont know why I watched it, especially why I watched the entire video, but it was completely worth it. (Still here, 7 months later. I can confirm, this video is STILL completely worth it and I absolutely watch it regularly)
reality is not a movie you stupid fuck! i hate loser liek you who think the government is soem sort of evil institution that seeks to hurt its citizens! you live in a fucking movie inside your head!
this is a very well made sales demonstration indeed. missing a few infos of interest. if i where in the constructoin field id love to visit a site with this equipment in action. so fluid animations from a technicians 3d program are not all that easy with all the components seen in this video. heck i spend a few days just making the assembly video for my examination back in the days. and it was passable at best by the standards we see today XD
Can I borrow your machine once in a while to dig some holes for fun too? I used to dig holes in my backyard just because I liked holes. This machine will make the job much easier.
This looks like a 21st century adaptation of Marc Brunel's (father of Isambard Kingdom Brunel) technique for sinking two 50ft diameter vertical shafts in 1825 during the construction of the Thames Tunnel. A cast iron ring is laid out and the soil was dug out from within the ring by navvies. As the material was removed it could no longer support the ring, which had cutting edge at its base, so the ring slowly sank. As it progressed down bricklayers constructed the shaft on top of the iron ring. The art was not to stop its progress downward to prevent the surrounding soil settling and gripping the shaft and preventing it going down further.. The Thames Tunnel is still in use today, its dimensions being large enough it is used for London Overground train services.
I was part on the team that sank in the late 70’s at North Shelby in UK. North Selby Mine was started in November 1979 and completed in July 1986 with a shaft depths of 1032m (No1) and 1045m (No2). Whitemoor Mine was started in February 1980 and completed in June 1985 with a shaft depths of 931.6m (No1) and 941.7 (No2).
I am not in construction, but the information contained in this video really brings to light a genius design. If I was in building tunnels and shafts, this thing would be my first pick, for it's mobility and what looks to me is a extremely smart design. All components serve a function and can be easily replaced, moved or supplemented. There is no wasting time and very few people are needed to making this work. As well as the ability of separating and cleaning the dirt, that's very cool! Genius!
What a clean shot to cascade one layer of RCC, over other and sank it, I feel blessed that I have done civil engineering. There are so many wonderful machines made by humans, yet to be explored by me.
as a technician i really understand you. it is somewhat satisfying to find these machines and seeing them demonstrated. even better when you had no idea they existed
I'm pretty sure this was engineered and innovated, not invented. Maybe a few components were invented to be patented, but most of the machine probably can't be patented.
This system of sinking vertical shafts was done by Marc Brunel (Isambard's father) in 1825 for works on the Thames Tunnel, obviously the digging was done by hand in those days. Using a cast iron ring with a cutting edge at the base of the shaft, the shaft walls being of brick. As the shaft sank the bricklayers built new courses on top.
I won't buy this for my little garden (5x7 meters...) for sure 😀, but this was really a very interesting piece of technology to watch. Thanks an good luck, guys!
Foundation work uses a smaller version with a Soilmech excavator equipt with a Kelly bar. Steel casing instead of prefab concrete than it can be removed if called for and reused. Concrete piling with steel rebar is Tremme poured to exclude ground water.
Another application could be below-grade placement of nuclear power plants, instead of containment buildings that are above-ground. I note the current upper limit of 18 m on diameter, but maybe the new generation of Small Modular Reactors (SMRs) could be designed to fit within this constraint.
So whats to prevent this kind of system from boring down through the crust? Seems to me it should be able to continue on until it hits magma since its covered in water.
I've been digging holes like that in the beach for sandcastle purposes for years now, but I have been doing it with a shovel. I want to upgrade my technique with some technology. What are your recommendations for vertical shaft digging tools that are human-powered?
cool... if it lives up its promises the reduced environmental impact is worth whatever the price differential with old school methods... does anyone know if it does?
this will not work properly on the moon. it may be possible to use a modified version of this if a way to compensate for the fluid transport problem can be found.
