I want to thank you for explaining and answering questions people asked along with your time doing so. Your very professional yet patient enough to talk to us in away we can understand unlike some others. Thank You
That's some really impressive work there. Having the escavator drive up onto the tunnel arch at the end was a great demonstration of the tunnel's strength.
Thank you very much. We're quite amazed at how well the structure performs. The keys between blocks have taken the traditional arch and made it that much stronger.
mibars depends on whats going to go over it, what the tunnel is used for and what the existing condition is. Sometimes a prefab tunnel is the way to go. I love the fact that they have the excavator sitting on top of the arch just after they constructed it.
LOVED it. Then drove to the top. I love it when a good plan goes together... Of course finding the "good" ones is the trick. Well done! Thanks for the video.
Impressive!$ Men can build heavy machinery and use it for so many different things...they do, and undo, replace, place, and displace as wanted, or needed. It amazes the heck out of me, but man cannot create peace, love, and stability in our own world...Thanks for sharing this stupendous work of art.
I'm impressed beyond words. That's amazing before thought engineering. That would be useful in offbeat any application, tunneling under a highway, railroad, survival housing..where ever..Way cool guys !!
Impressive system, like the way you thought it all through. I was also impressed that even with the back fill not compacted that the machine didn't increase the thrust to the point that the springing spread apart. But then, the voussoir's are probably over specified and with the cost of the raw materials why the bloody hell not !
lol.. I'm sure it took a lot longer, when backfilling and compacting the outside.. I think this is THE most important part of the well being of this structure.. .
Anyone who understands basic mechanical forces will understand where the support comes from ;) but sweet and educational video. I strangely enjoyed watching it..
awesome. what 2000 year old technology of the arch brought up to current times. Love it. PS didn't realize those were rollers on the truck until it was part way out.
That would make an amazing storm shelter. I'll bet there are a few people around Oklahoma City that would love one in their back yard, or maybe a few around the schools.
I love it. I would love to have something like that as a basis for a tiny house. Think of how cool it would be in the summer. That is all the space I would need.
It's really fascinating that there does not appear to be any kind of fasteners from block to block and it is just friction and gravity keeping them together. With a little modifications to the process, this would be a cool way to build under ground houses...
I worked for a company called steelmaster that made similar quonset hut style structures. they were prefabricated steel arch style structures. No load barring walls though. you'd have to manufacture you're own end walls for that.
this is awesome. the roller-wedge-thing you have there is brilliant...ish. the driver is not protected from being crushed if the truck backs up too far or something. other than that, I'm impressed
interesting, but my first thoughts were how important it is that the first run of blocks be absolutely stable. the force gets pushed down, but when it's tested in a variety of ways, (like your excavator getting on top of it from the side first) the pressures on the first row could also be outward, which would be extremely destabilizing. thanks for the vid.
This is a great arch making system i hope the roller bed has a nick name (armadillo) that is a very good demonstration especially at the end with the lets park the unit on top. .
Thank you for your support! We have a name for the truck; we call it the "Zipper truck" because it holds the arch apart like a zipper until it drives forward.
as a civil engineer, I love this!! Im assuming you could use this tech for pedestrian walkway or wildlife crossing tunnels? I have used con-span tunnels for pedestrian trails and those worked well, but I think this would be a a nice alternative.
The waterproofing step would be after the arch is completed and the final product isn't shown in this video. The arch is waterproofed very simply as you saw in our other video. Not every project needs waterproofing, and this one does not. Thank you for your comments and we hope you'll subscribe and continue to follow our technology as it evolves.
There are no after videos unfortunately. The truck is a standard flatbed truck with our custom frame on the back. We can control the height of it as well as the slope in order to facilitate installation of arches at different heights.
Genius! It's so simple. I would have thought about an inflatable set of cilinders that can move in or outwards by inflating or deflating them. To settle the rocks at certain positions.
Wow! This is just awesome! Reminds me of the LEGO's I played with... Only BETTER! This is just so C.O.O.L & the installation precision is so damn neat to witness.
Probably, the blocks have to be spread out to get the closing top piece in, then when you move the truck forward they will lower and close up all gaps as you can see near the end of the vid when the truck comes out...
+john apple The idea is that your move the truck forward and then the blocks fall and lock into each other, makes putting the friction locked blocks together easy.
It looks like the flatbed trucks roller supports are tapered to decrease in radius towards the rear which is clever, but I wonder if you considered an actuated system where the truck could stay in place and the radius could be decreased or increased perhaps along different sections of the truck to facilitate Keystone installation
Why are people in the comments surprised the arch has the strength to support the caterpillar, even though the arch has been used since ancient Roman times to support much, much more weight?
Is there a sealant you can put between the blocks as you go? Similar to a mortar. I live in the PNW Rain forest and extreme waterproofing is the order of the day.
LOL! for a second i was thinking... thats one sketchy looking tunnel... about to collapse at any moment ... then that big ass thing climbs on top of it HAHAHA
+mattgotsskill These types of arches was invented by the romans. It is used all around the world for building bridges, and has some inherent amazing physical traits. science.howstuffworks.com/engineering/civil/bridge5.htm
Jørgen Skår Fischer i believe the the history of the keystone arch is debatable , many believe it was created by the earliest Freemasons , and later adopted as they traveled and built magnificent arched structures around the world
The tunnel is designed to take material from the mine for processing. It's a way to keep rainwater off of the material to minimize environmental impact from the mine tailings.
THAT is cool! Does the "mandrel trailer" for lack of a better word ever get smashed down into the mud? Do you need compaction below so the truck doesn't settle while you're placing the blocks?
It'll serve nicely as one. If properly buried, could even take a nearby nuke strike of 100-300kT at 2 miles. Overhead, on the surface, the overpressure would be 10 to 15psi, momentary earth movement equivalent to a 7-8.0 Richter scale earthquake. Movement also on the order of a few inches or so at the surface, creating one hell of a dust cloud, aka ground shock.
Can anyone explain to me what a reclaim tunnel is? What is the function/purpose? My completely uneducated guess is that it is for after taking a bunch of dirt or whatever and effectively filling the hole so the surface is still flat.
Like any other engineered earth structure, drainage is an important design consideration for the engineer. The arch can be made water tight very easily by adding a membrane and backfilling with proper gravel and drainage pipes.
Would the truck also when the ground isnt leveled? Maybe you should put hydraulics on the front and back to tweak it when the ground is uneven or soft. Also why polymer wheels on the truck roof? wouldnt rubber last longer?
We have a hydraulic system on the drawing board for the zipper attachment, and we are refining it to be modular so it can be moved to other vehicles as needed. The ground should not be uneven or soft if the site preparation is done properly. If it's uneven, making any retaining wall structure is complicated. The wheels were chosen not only for durability, but for the ability to hold the load without deformation.
Wow! I could see this being mounted onto a huge CAT dump truck like the Caterpillar 797 for conventional tunnels for transportation. Finally we can a break on all the tolls lol Great job guys - making life more affordable for us - I LOVE CAPITALISM!
kawivloger We definitely hope to see this system replace conventional construction techniques just for that reason. It's far cheaper than the existing system and will save the taxpayer lots of money.
I want to thank you for explaining and answering questions people asked along with your time doing so. Your very professional yet patient enough to talk to us in away we can understand unlike some others. Thank You
There is something mesmerising about heavy machinery in action and those that know how to use it. Great video gentlemen.
าท . พพพ ง
+peterpurpose Agreed. I imagine the back hoe operator and the signaler have to have a pretty good understanding with each other too.
That's some really impressive work there. Having the escavator drive up onto the tunnel arch at the end was a great demonstration of the tunnel's strength.
Thank you very much. We're quite amazed at how well the structure performs. The keys between blocks have taken the traditional arch and made it that much stronger.
+Lock Block Ltd. legos. you made concrete legos. and they are AMAZING
This is so cool! Way stronger than prefabricated tunnel structures!
mibars depends on whats going to go over it, what the tunnel is used for and what the existing condition is. Sometimes a prefab tunnel is the way to go. I love the fact that they have the excavator sitting on top of the arch just after they constructed it.
doubleg137 It said this was a demonstration video but I wonder what situation you would use this with.
Since when have there been hard hats that look like cowboy hats? truly Amazing.
LOVED it. Then drove to the top. I love it when a good plan goes together... Of course finding the "good" ones is the trick. Well done! Thanks for the video.

That driver is very delicate and skilled, congrats for the team work !

Wow pretty impresive. Building that solid tunnel in just 10-20 mins. Good work
lol.. I'm sure it took a lot longer, when backfilling and compacting the outside.. I think this is THE most important part of the well being of this structure..
.
The wheels to sneak the form out from under---stroke of genius.
Anyone who understands basic mechanical forces will understand where the support comes from ;)
but sweet and educational video.
I strangely enjoyed watching it..
Diggers are so versatile! Also that digger operator is pretty good as well.
awesome. what 2000 year old technology of the arch brought up to current times. Love it. PS didn't realize those were rollers on the truck until it was part way out.
That would make an amazing storm shelter. I'll bet there are a few people around Oklahoma City that would love one in their back yard, or maybe a few around the schools.

The loader operator is especially awesome
very clever. this would be the best storm shelter on the market.
Man! When the excavator went over tunnel! I wasnt sure what was going to happen! Cool video
That's really terrific. Putting the crane on top of the dome is the clincher. Good job guys. Pete
Smart way to build Vault 13.
Good teamwork and a good excavator operator right here. Loved it.
Ancient roman construction, after 4000 years. Still looks like an impressive construction. It really is tho.
May I say that it is way much older than roman engineering...
Super skilled operators. A great video.
I worked for a company called steelmaster that made similar quonset hut style structures. they were prefabricated steel arch style structures. No load barring walls though. you'd have to manufacture you're own end walls for that.

By about 1:00 I had a serious urge to grab some Lego... LOL
+Gaming With ViperZeroOne You sir are not alone ! :D it's like lego, but, a real lego tunnel :D except without toy lego. If you get my drift :D
Absolutely!
Nice! I bet the Romans would love to have used this to help with their Amphitheater construction!!!
This is a great arch making system i hope the roller bed has a nick name (armadillo) that is a very good demonstration especially at the end with the lets park the unit on top. .
Thank you for your support! We have a name for the truck; we call it the "Zipper truck" because it holds the arch apart like a zipper until it drives forward.
Yep i can see that as a good name :)
Lock Block Ltd. I think you should call it the "Porcupine" That's what it reminds me of.
Building temporary supports is a wastefull tiresome hassle, this is a great idea, love it, fast, simple, easy.
Learned something new, glad I came across this video, thanks for posting it!
interesting enough, the engineering is as old as the Roman empire (was). The use of the truck makes it a modern approach, nice.
9:53
Ok, its done, but that tunnel doesn't seem too strong to support much wei-.... oh..... it... it will go o-... over it?!... damn....@____@
+TJChagas Yep .. I was considering the same thing, then I saw that .. WOW !!
Aches are very strong!! Designed has been used for thousands of years!!
+TJChagas Ha I thought that too.
+TJChagas They parked an excavator on it.. Wtf are you talking about... Over 80000 lbs is not enough for you?
shadywalker text comprehension/interpretation. Read it again...
Wow. That's an awesome system and construction method.
in staed of roller in zipper arch truck ,you can use Hydraulic piston connected parallels together. so you can move out the truck in one step.
It's about time someone thought of that!
as a civil engineer, I love this!! Im assuming you could use this tech for pedestrian walkway or wildlife crossing tunnels? I have used con-span tunnels for pedestrian trails and those worked well, but I think this would be a a nice alternative.
Quite a successful project... Thanks for showing.
really cool! I certainly didn't expect backhoe to ride on top. I'm impressed
Funny looking shovel !! Looks like a 30 Ton Digger to me.
wow this is some smart working ,thmbs up guys ....
Much much smarter than the first one using chains. you did skip the waterproofing.
The waterproofing step would be after the arch is completed and the final product isn't shown in this video. The arch is waterproofed very simply as you saw in our other video. Not every project needs waterproofing, and this one does not. Thank you for your comments and we hope you'll subscribe and continue to follow our technology as it evolves.
I did consider attempting this same idea but using regular block with some sort of shim and just grouting the wedge. Your solution worked out well.
i used to do this all the time when i was a kid
davetileguy Yes,but there is still a hole in the top...
Very Nice demo of 3 mt Tunnel preparation with preecasted cement blocks with inter locking projections.
Regards
S S Rao
All of this is very good to look at.
Well, thumbs up for that demo.
This is cool very innovative, where is the company based?
Joe Gaffney Vancouver, British Columbia.
+Lock Block Ltd. Canadians rule
+Joe Gaffney Yes, the company is based
+Lock Block Ltd. Canada , for those confused by the Vancouver ,British Columbia part.
Joe Gaffn
only a mack can handle the load. love seeing them old mack trucks in action
I would love to build a castle with those.
You need to see the video about the guy who "printed" a small castle using a 3-D concrete printer.
truly amazing engineering - any video of the "after" tunnel? was the truck modded in house or did you purchase the roller system somewhere?
There are no after videos unfortunately. The truck is a standard flatbed truck with our custom frame on the back. We can control the height of it as well as the slope in order to facilitate installation of arches at different heights.
Lock Block Ltd. too bad, maybe I'll visit one day :) What a cool technology very impressed!
Patrick Coombe I am more impressed by the skill of the backhoe operator. Real smooth.
+Lock Block Ltd. Is there a version of it for a wider tunnel, perhaps for a two way tunnel? anyway it's amazing. Congrats !!!
+ หชกยPatrick Coombe
Genius! It's so simple. I would have thought about an inflatable set of cilinders that can move in or outwards by inflating or deflating them. To settle the rocks at certain positions.

should put your roller system on hydraulics, lower or raise to help them ease into lock position
Is the trailer piece tapered? Looks like it kinda declines in angle towards the rear of the truck. Very insightful and entertaining.
Probably, the blocks have to be spread out to get the closing top piece in, then when you move the truck forward they will lower and close up all gaps as you can see near the end of the vid when the truck comes out...
+john apple The idea is that your move the truck forward and then the blocks fall and lock into each other, makes putting the friction locked blocks together easy.
john papple the decline slides them in place instead of dropping them in place.
So simple. Thanks Lego.
That excavator deserves a raise.
Egyptians did this thousands of years ago. Lock block technique.
Very nice video!
amazing how quick its assembled !
the escavator driver is awesome tho
That is an awesome upgrade to Lego blocks!
How cute... there are even people with yellow heads in there, just like real Lego :) ;)
And that's how you built the tunnel to the BATMAN CAVE! Ha ha ha... xD
very smart and simple solution to building.
I like the cowboy hardhat with safety duster
+Brett Brown It's a hard hat, Look at it closely.
It looks like the flatbed trucks roller supports are tapered to decrease in radius towards the rear which is clever, but I wonder if you considered an actuated system where the truck could stay in place and the radius could be decreased or increased perhaps along different sections of the truck to facilitate Keystone installation
Come to think of it you could just put it on an old flatbed tow truck and then you'd have your hydraulic actuated radius changer
Impressive work!
Why are people in the comments surprised the arch has the strength to support the caterpillar, even though the arch has been used since ancient Roman times to support much, much more weight?
nice Lego blocks , cowboy Joe !
Now that's what they need under Stonehenge on the 303.
Is there a sealant you can put between the blocks as you go? Similar to a mortar. I live in the PNW Rain forest and extreme waterproofing is the order of the day.

***** ya i know what its called. but to emphasize my feelings on the subject matter. i called it a ( Big Ass Thing)
this is so amazing,
Wow!! Great engineering!
Excellent work
Cross shaped extended connecting points for the arch... Nice choice...
What is a mining reclaim tunnel?
The tunnel is designed to take material from the mine for processing. It's a way to keep rainwater off of the material to minimize environmental impact from the mine tailings.
THAT is cool! Does the "mandrel trailer" for lack of a better word ever get smashed down into the mud? Do you need compaction below so the truck doesn't settle while you're placing the blocks?
You learn something every day.
yeah the operator knows his machine!
nice demostration
Beautiful tunnel!
Is it the standard tunnel, what is formula to maintain standard??
so this is like a bunker?
It'll serve nicely as one. If properly buried, could even take a nearby nuke strike of 100-300kT at 2 miles. Overhead, on the surface, the overpressure would be 10 to 15psi, momentary earth movement equivalent to a 7-8.0 Richter scale earthquake. Movement also on the order of a few inches or so at the surface, creating one hell of a dust cloud, aka ground shock.
I absolutely love this idea.
Can anyone explain to me what a reclaim tunnel is? What is the function/purpose? My completely uneducated guess is that it is for after taking a bunch of dirt or whatever and effectively filling the hole so the surface is still flat.
Did you guys drink some Keystone afterwards?
Very impressive. Very clever.
Roman building style, I love it!
kool. would make my underground home an easier thing to create with this kind of tech.
guy on the shovel is no slouth. he is what we call an ' operator '.
Water Tight ?????. and whats to stop the bottom blocks pushing in if water gets down the outside and turns the backfill alluvial ????
Like any other engineered earth structure, drainage is an important design consideration for the engineer. The arch can be made water tight very easily by adding a membrane and backfilling with proper gravel and drainage pipes.
: 30 into the video ~ the guy pushing the block with a broom. ~ VERY FUNNY !
Awesome! Fantastic! Fascinating!

We need this in the U.S.
