Tunnel Boring Machine Completes Hole Under Niagara Falls

Soulskill posted more than 3 years ago | from the also-known-as-geohacking dept.

Canada 193

abhatt writes with news that "Big Becky," a 4,000-ton tunnel boring machine, has finished chewing through over 10 kilometers of rock underneath Niagara Falls, Ontario, a project that's been underway since 2006. "The 10.2 kilometer tunnel is 14.4 meters in diameter. Big Becky ate through 1.6 million cubic meters of rock to reach her goal. That’s enough rock, officials said, to fill the Rogers Centre in Toronto. And the cement used to line the tunnel would build a sidewalk stretching from Windsor to Quebec City. ... The project took longer and cost more because Becky ran into unexpected conditions. She’s designed to go through solid rock, but encountered a stretch of loose, crumbling material that was unsuitable for tunneling. That forced a long and expensive detour."

To be fair, the print is relatively small.

The project was to up upgrade [opg.com] the existing hydroelectric generating stations [wikipedia.org] that currently generate a little over 1.9 Gigawatts of electricity from the waters of the Niagara River. The Niagara River (on which you will find Niagara Falls [wikipedia.org] ) flows between the two Great Lakes [wikipedia.org] , Lake Erie [wikipedia.org] and Lake Ontario [wikipedia.org] . It will add around 200 MW of power generating capacity. This [ontario.ca] would have been a better news release article and explains a bit of the "green" projects in Ontario.

There: all you ever wanted to know about WTF the OP's linked article should have told you. FWIW, I agree that the OP's linked article is pretty lame. But that's nothing new for mainstream journalism. But I have to admit, Canadian news media that were once pretty damned good, are now pretty damned weak (Leaving out important contextual information, inability to spell, lack of grammar skills, just not understanding what the fuck they are reporting on and too lazy to find out).

I thought they could already divert so much water through the hydropower tunnels that they have laws to mandate minimum flow rates at the falls to maintain the waterfall spectacle. Don't the new tunnels draw from the same water source?

Motivations of Society, wealth or fear. (0)

Anonymous Coward | more than 3 years ago | (#36146586)

At first, I would be concerned with the manipulation of the natural paths over water from collective precipitation, but then
considering the vast amount of energy to capture someone would think that it was a good idea.

The discernment of that motivation, is reflected at the smallest unit of the planet, to collect what others would want or need, and doing it before your competitors. Yet still, this is motivation to collect free energies with only shallow preparations of the known effects that could be potentially disastrous.

Consider the following video, http://www.youtube.com/watch?v=LIkgXTQetX8 [youtube.com]

Is wealth become the new fear, that if one does not claim these unharnessed resources then such opportunity might not present itself again?

Surprisingly, the article doesn't even say why they drilled it, other than it being related to energy production.

Also, IT'S NOT FUCKING CEMENT, IT'S CONCRETE.

Cement is an ingredient of concrete. It is not the finished product. Calling concrete "cement" is as stupid as calling clothing "cotton", or calling a sandwich "mayonnaise". Once you apply the mayonnaise to bread and add some lunchmeat, your creation has become a sandwich, and it is no longer simply mayonnaise.

Yeah, I get that fucking irritated by this.

Darinbob (1142669) | more than 3 years ago | (#36147302)

Someone eats a tuna sandwich and you ask him what he's eating and he says "tuna". Some people call their sidewalks "cement sidewalks" because cement is indeed a principle ingredient and the meaning is very unambiguous here in context. Everyone knows what they mean. In summary, there can be more than one word for the same thing!!

This is all a part of the English language. It evolves over time and words change their meaning and the majority of people learn to live with. To me it is unfathomable why someone would complain that "unfathomable" is being used incorrectly in this sentence merely because we're not actually measuring the depth of deep water. People may try to write down official rules but language isn't going to obey them.

Re:No, I'm not going to RTFA just to find out (0)

Anonymous Coward | more than 3 years ago | (#36147360)

Pedant fail; I believe the original sentence holds up. Possibly not on purpose, but still acceptable interpreted literally.

the cement used to line the tunnel would build a sidewalk stretching from Windsor to Quebec City.

As you can see, they're not writing they lined the tunnel with cement, they're saying they used cement to line the tunnel. And as cement is a part of concrete, they did indeed use some amount of cement to line the tunnel, the same amount of which presumably, together with some gravel, sand, water and miscellanea could be used to build a sidewalk stretching from at least one of the cities, towns or villages named Windsor to Quebec City.

Pretty sure if you use enough concrete to build a sidewalk from Poughkeepsie to Chickautagua, you're going to need enough cement to build a sidewalk from Poughkeepsie to Chickautagua.

Re:"Rogers Center"s? (1)

Anonymous Coward | more than 3 years ago | (#36147448)

Rogers Center (AKA Toronto Skydome [wikipedia.org] ) is the host stadium for the Toronto Blue Jays baseball team, so it isn't any more metric than a typical US stadium. Anyway, think "typical major football/baseball stadium size" and you'll be fine.

On another page it's mentioned that the tunnel will supply 500 cubic metres of water per second [opg.com] , which they helpfully convert to 17660 cubic feet per second if you really want Imperial measurements. It's apparently enough to fill an Olympic-style swimming pool in seconds. Wow. Well, we are talking about a 14 metre tunnel (think ~14 yards, for the metrically-impaired) and a lot of pressure driving it.

I wasn't able to find an official "volume of the Library of Congress" for either the buildings (there are several) or for stack space, but I was able to find out that it has approximately 838 miles of bookshelves [loc.gov] . Bookshelves aren't exactly standard sizes, but assuming it is a 12-foot stack and 1 foot deep (both of which are probably way off, but must be within an order of magnitude), that would be 838miles * 5280ft/mile * 12ft * 1ft = 53 095 680 ft^3, which sounds huge. By comparison, Royal Albert Hall in the UK is 3 to 3.5 million cubic feet or 85 000 to 99 000 cubic metres [wikipedia.org] . Anyway, divide by 17660 ft^3/s, and there's your answer: roughly 3006 seconds, or, ye gods, you can fill entire the shelf space of the Library of Congress in under an hour???!!!

If anyone can find official "volume of the Library of Congress" in terms of books or buildings, it would be appreciated.

That's what the other links are for. Click on the "Big Becky" link, then the others in the "Niagara Tunnel Project" [opg.com] . It's a big hydroelectric project using the Niagara River at Niagara Falls. The other information includes: "Why at Niagara?" [opg.com] , which explains there is excess, unused water allocation on the Canadian side of the river due to the shutdown of several old hydro plants near the falls (the river is shared between the USA and Canada), and excess generating capacity at the already-existing Sir Adam Beck generating station [opg.com] further downstream, if the water could get there. Thus, the tunnel connects the input above the Niagara Falls to the generating station downstream of the falls, augmenting the other supply that already goes to the station (a canal and pre-existing tunnels). There's a nice map and cross section here [opg.com] .

blair1q (305137) | more than 3 years ago | (#36147436)

It's the stuff constantly dumping on the top of the borer instead of falling and being sucked up by its front end. These things run on rails, so except for the first few meters their workspace needs to be relatively clean.

It's also much harder to stabilize loose stuff for use as a tunnel, and almost impossible to trust your load calculations. Nice, hard rock eliminates all that. Just throw in some cleats, spray on the gunite to seal cracks and prevent loose crap from becoming debris, and go to lunch.

So, solid rock needs vastly less after-drilling support structure than loose material, which wants to subside into any opening like sand through an hourglass. And, the geologic conditions can vary wildly foot-by-foot, rendering the design of the tunnel casing impossible until the conditions are actually encountered. Not the stuff of schedules or budgets. Going through solid rock allows the pre-fabrication of standard concrete casing segments that can be placed after the concrete has cured to its design strength, making for repeatable operations, and a homogeneous end product. Stakeholders like that.

Maybe not there... (1)

But other tunnel boring projects do anticipate this sort of thing. I'll point to the city of Seattle and Washington state, which plan to replace an elevated freeway with a deep bore tunnel. Not through solid rock, but through glacial till material that is the equivalent of mixed dirt and gravel. Apparently the tunnel engineers don't think it will be a big problem to drill through it. (It will be hard on the drills themselves, but they can do it.) I think they're more concerned about the tunnel collapsing afterwards. Which was likely the concern at Niagara Falls too had they gone through something other than solid rock..

Kinda reminds me of high pressure water cutting: it does cut steel and such easily but fails on soft (cream) cake...

This problem fails to be funny once you realize that hitting a non-solid geological formation while boring through the ground means that you are forced to consider the possibility that a huge-ass ton of rock can suddenly crash on top of your head and that the little 10km tunnel you are currently in can suddenly be flooded.

Obviously you've never had the experience of being suffocated by a ton of gravel falling on your head after hacking away at that diamond ore block on the ceiling!

I'm not surprised. Then again anyone that's lived in Ontario and parts of NY/MI for most of their life already know that dirt varies from a few feet deep to several dozen feet deep or more. There's that whole 'scraped the topsoil off the canadian shield for several thousand km' thing and dumped it here thing that I guess these guys didn't look into.

Kind of funny that it ran into a timely detour because it hit a spot that WASN'T solid rock.

Amazing that level of optimization fails due to loose dirt.

What's so funny or amazing about it? If you drill a hole through loose dirt, it ceases to be a hole seconds later. This has nothing to do with 'optimization'.

It's a drug smuggling tunnel! (1)

The 10.2 kilometer tunnel is 14.4 meters in diameter. Big Becky ate through 1.6 million cubic meters of rock to reach her goal.

Those sneaking Canadians digging a drug smuggling tunnel. It's either that or they plan to sneak their armies across the border and invade.

One of those.

Replace "armies" with "platoon" and your comment might actually make sense ...

It's like when you bring 10 pickaxes, find mostly dirt, then you realize you foolishly forgot to make even a couple of shovels.

Shovels? How un-dwarven. Real dwarves part the dirt with their beards.

Is that not the very reason to always carry a crafting table, and a bit of wood with you? I generally just craft shovels when I need them.
