Its powered by a electric motors that turn the drill head .Its easy to change direction and speed on system There is also electric motors that drive the oil power pack that pumps oil to power the rams that clamp the tunnel walls this means the TBM can be pulled back from the cutting edge it can only go back so far because the tunnel new wall linings make the tbm to big to pull back.I suppose the whole unit could back up if you removed all the tunnel lining .
A few questions on the TbM is it powered electric ? Whats the max distance you can bore would it do 120 km underground land over head/few lakes and rivers over head.? The cost per meter/ kilometer to bore.Can it drilling hard rock or is it soil mainly its boring .
TBMs are powered by electricity. They can bore through ground regardless of what it overhead, but there is almost certainly a minimum distance required between the top of the machine and the bottom of any water body. TBMs can cut through all but the hardest rock types. Even where rocks are present that the TBM can cut through, drilling through softer materials is quicker and cheaper since there's less wear on the cutting teeth (fewer replacements needed, plus TBM cutting head needs to stop for several hours). For example, the Channel Tunnel was drilled with TBMs and was routed to follow a stratumof softer soil to save time and money. As a result it is not level, but goes up and down. I think the main limit on the distance a TBM can bore is the durability of the cutting shield. Cutting teeth and much of the machinery inside the TBM can be replaced while tunneling, but the cutting shield can't. So the distance would depend on soil type.
Cost per meter/kilometer to bore has to many factors. The cost of the machine is fixed, so shorter tunnels are more expensive per kilometer. Transporting and setting up the machine is expensive. TBMs are usually operated by a small staff of employees who are experienced with operating them, adding a small amount. Then there's the cost of labor and producing the panels, which varies among sites. If boring under a city (eg. subway line), there's the cost of monitoring the ground above the tunnel for movement. And that's just the cost of boring and leaving behind an empty tube. That's all for a water pipe, but twin-tunnel train and vehicle tunnels need frequent cross-passages drilled for safety in case of a fire. Then concrete needs to be poured for a level surface to drive on, utility ducts need to be created for electricity, ventilation, cables to monitoring equipment, and (in some tunnels) water to fight fires (search UA-cam for tunnel deluge test).
Thanks for the reply . I had a idea for a flood control tunnel / canal depending on the route and ground levels at different point to divert flood water from a river around mid point and sent part of river straight to sea. Its the river Shannon in Ireland . Take a look at the idea sometime and feel free to leave a comment .
Now im not the smartes guy in the world but, couldn't you guys have modified the mixing chamber with some kind of feeding tube that works with pressure or hydrolics, and would now connect to an errection system to convey the smuck out of there and eliminate the screw conveyor. As I watch this video i get so many ideas of intricate mechanics works and what not. Thank you this video is fascinating.
I think that perhaps the reason for the screw is because it works better than pressure or hydrolics to get on the conveyor, keeps it from getting clogged and makes sure it gets to point B
I would like to go down about 40,000 meters to reach approximetly 1000c. I know that that is pretty hot but think of liquid nitrogen to chill the cutters. That might be psible? Once drilled the use of liquified salt would bring the heat to the surface. Now that would do a lot of things, like electric super clean generation.It could desalinate salt water liquify coal to make supper clean diesel and make fertilizer as well. I have the Idea and hope I can spread it around for free.
I don't think concrete tunneling would hold up at that depth. liquefied salt would limit the heat transfer rate heavily. desalinating the water water would be economically unfeasible. where does the fertilizer come in? a heat pipe like system once you got further up the tunnel would move the heat better and over 40,000 meters you would lose a lot of heat over the journey without amazing insulation. arogel and vacuum sealed are about the only options i see there. and if there is an earthquake the molten salt would be under huge pressure and damage or destroy the infrastructure on the top. i heard about some rich guy who wanted to run bundles of carbon nano-tubes down deep to mine heat. they would hold up to the pressure and heat better. still he has an insulation issue. vacuum sealed panels would be counterproductive to tunnel stability and aro-jel is incredibly fragile.
Can any body educate me that certain chemicals are used during Tunnel boring operation abd these are very poisonous and pollute the entire water belt for a distance of 30 meters on either side of the underground tunnel.Is there nt any chemical substitute which is not poisonous and still serves the purpose. What is the purposed of using the chemical. I need help
i head the new Skytrain Line Public Service was originally due Summer 2016. but moved to Fall 2016 due to the slowing process of the TBM. because of the 2 sinkholes during boring. my possible predictions are that there could be new sinkholes on clark road, which can cause serious injuries and worst possible cases: death.
I want to build a canal cutting machine. It would cut a slot thru the earth in less time than the old fashion way. Basically, it would be a huge huge circular saw designed to cut thru soil and solid rock of all types. The idea is to cut a canal the distance from San Diego all the way to the Gulf of Mexico. Thus connecting the Pacific Ocean to the Gulf of Mexico, thus redirecting all shipping traffic from the Zika Infected Panama Canal to The American Canal. It would be powered by portable windmills or nuclear energy. If you can give me an estimated cost of a single machine, I can get the ball rolling on Kick Starter.
architecture. see the person that designed the scrap cutters. He started with large electric motors. Put some of the coal into it. It takes a clinton to bounce a village.
Ms Clinton is quoted in saying it takes a village to raise a child. That is because the mortality rate in a village is extremely high, so they pass the child on to the next person. That is until the child die of abuse, malnutrition, runs out of relatives, or disease. She is trying to repackage Socialism in a quaint image of a village. The whole concept of creating a new canal from California to the Gulf of Mexico isn't really meant to keep people out, but to provide a new source of water for every body between those two end points, including Mexico. Water will become a very important resource in the coming years.john halamka
@@MrPanetela why not just desalinate the water from the ocean? same way a still works? you get salt and with processing that much water gold as a byproduct. only needs heat to run which could be produced by a combination of solar, tidal and wind power which are all available along the coast. a tidal generator with a floating array of solar panels over it and wind turbines in donut shaped balloons high enough up to get the perpetual source of wind high enough up.
@@NuclearLama many do not understand what a salty ocean is about. Salt in the ocean helps to control the humidity. Earths original ocean was salt-less, as a result run away storms was the norm. Think world wide typhoon 24/7. Introduction of plastics has changed all that. The micro-beading of decaying plastic disrupts, the balance of humidity. When plastic particles enters the upper atmosphere, cat 5 hurricanes result. Expect to see 6 and 7 cat hurricanes in your lifetime.
An amazing video whuch answers EVERY single question I had about how this works. 10/10
You just saved my school presentation, thanks! :D
I will be working in it!!! Very exciting!
Awesome animation! Just watched a documentary on the English Channel Tunnel construction and was curious on how TBMs worked.
Fantastic ! wonders of Technolgy.
Does Home Depot carry this? The drill bit better last the full 90 days otherwise it's getting returned!
i have been looking for answer of tunnel boring machine, how long does it takes to boring tunnel for one kilometer ?
Khalid's ArenaWorld we have bored 6 kilometres through granite rock with an 8 metre tbm in 24 months
14 months sorrry
Dirk Diggler
Wow what is your job?
I'm looking at purchasing one of these, do you have a quote? And do I have to include the concrete walls part or is that a part of the package
What happens if you run into a large patch of iron?
iAndy You smelt it and use it to make a pyramid for your beacon
you can scan ahead with metal detector to avoid it.
@@NuclearLama how deep they can go?
if this machine gets stuck/jammed is there a process to reverse the machine, or can it only be retrieved at the other end of the tunnel?
u can stop the boring anytime.. otherwise it would be boring

Who is moving the concrete segments onto the erector arm? Seems like they just magically float by themselves without any assistance.

+John O Brien I think TBMs have been used to bore tunnels to divert water around dams. Shouldn't be much different to divert water from a river.

awesome
This machine isnt boring, I found it quite interesting. wakka wakka
How far would a boring machine drill in 24 hrs
we should automate one of these things and send it straight down. see what the center of the earth looks like.
Magma = 1600 °C, melting point of steel = 1370 °C. Earths crust is only 20-50km thick until hit magma.
Extraordinary .. love from india
at 1:09 where are the new spirals coming from?
They're rotating and gives the illusion of coming out of somewhere
