3m reclaim tunnel demonstration

[@MYTOYMAKERZ]

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

[@peterpurpose]

There is something mesmerising about heavy machinery in action and those that know how to use it. Great video gentlemen.

[@โด่งละแม]

าท . พพพ ง

[@ConditionOfMan]

+peterpurpose Agreed. I imagine the back hoe operator and the signaler have to have a pretty good understanding with each other too.

[@miriammaldonado7848]

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.

[@obliviousfafnir01]

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.

[@LockBlockLtd]

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.

[@merlinious01]

+Lock Block Ltd. legos. you made concrete legos. and they are AMAZING

[@natelarge]

Since when have there been hard hats that look like cowboy hats? truly Amazing.

[@mibars]

This is so cool! Way stronger than prefabricated tunnel structures!

[@doubleg137]

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.

[@LivingSquirel]

doubleg137 It said this was a demonstration video but I wonder what situation you would use this with.

[@connieskoipond6551]

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.

[@ovalwingnut]

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.

[@bartonrobinson4266]

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 !!

[@duramirez]

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

[@FredRorex]

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...

[@MrJonmaine]

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 !

[@mathman1923]

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.

[@Herdol90]

Wow pretty impresive. Building that solid tunnel in just 10-20 mins. Good work

[@QMDiver]

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.. .

[@xuvial1391]

Diggers are so versatile! Also that digger operator is pretty good as well.

[@davidsmith-kh8cs]

very clever. this would be the best storm shelter on the market.

[@John-gm8ty]

Anyone who understands basic mechanical forces will understand where the support comes from ;) but sweet and educational video. I strangely enjoyed watching it..

[@guntherultraboltnovacrunch5248]

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.

[@timsharp8233]

The loader operator is especially awesome

[@iakopo79]

Man! When the excavator went over tunnel! I wasnt sure what was going to happen! Cool video

[@patrysie71]

Good teamwork and a good excavator operator right here. Loved it.

[@doubleg137]

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.

[@freezingthedarkness]

Ancient roman construction, after 4000 years. Still looks like an impressive construction. It really is tho.

[@JamesKagelberg]

May I say that it is way much older than roman engineering...

[@daves.9479]

The wheels to sneak the form out from under---stroke of genius.

[@AAAyyyGGG]

Nice! I bet the Romans would love to have used this to help with their Amphitheater construction!!!

[@Automedon2]

Super skilled operators. A great video.

[@normanmcgill9532]

That's really terrific. Putting the crane on top of the dome is the clincher. Good job guys. Pete

[@thomasdemaio53]

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

[@yoblazes]

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.

[@johnsmith-wi2lb]

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.

[@ZerozenOnes]

That is an awesome upgrade to Lego blocks!

[@jm-ux5dk]

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. .

[@LockBlockLtd]

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.

[@jm-ux5dk]

Yep i can see that as a good name :)

[@geedubb2005]

Lock Block Ltd. I think you should call it the "Porcupine" That's what it reminds me of.

[@timtravasos2742]

Wow. That's an awesome system and construction method.

[@pvopop4938]

Building temporary supports is a wastefull tiresome hassle, this is a great idea, love it, fast, simple, easy.

[@oBseSsIoNPC]

interesting enough, the engineering is as old as the Roman empire (was). The use of the truck makes it a modern approach, nice.

[@remember25october]

Smart way to build Vault 13.

[@GrouchoTM]

really cool! I certainly didn't expect backhoe to ride on top. I'm impressed

[@code123ns]

How cute... there are even people with yellow heads in there, just like real Lego :) ;)

[@rayeyers2902]

Funny looking shovel !! Looks like a 30 Ton Digger to me.

[@kevinolesik1500]

nice Lego blocks , cowboy Joe !

[@isabelle317]

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.

[@labrat748]

Learned something new, glad I came across this video, thanks for posting it!

[@charlieabbot3649]

It's about time someone thought of that!

[@ronaldbonnick9223]

All of this is very good to look at.

[@Junktiques4u]

Egyptians did this thousands of years ago. Lock block technique.

[@joehanna2231]

Well, thumbs up for that demo.

[@rubber20021]

Quite a successful project... Thanks for showing.

[@joegaffney1959]

This is cool very innovative, where is the company based?

[@LockBlockLtd]

Joe Gaffney Vancouver, British Columbia.

[@CameranMovies180]

+Lock Block Ltd. Canadians rule

[@obamer1342]

+Joe Gaffney Yes, the company is based

[@TriniCrew]

+Lock Block Ltd. Canada , for those confused by the Vancouver ,British Columbia part.

[@arina.zubcovtdhh4150]

Joe Gaffn

[@MrSam88473]

very smart and simple solution to building.

[@33sixpack]

You learn something every day.

[@s0nnyburnett]

So simple. Thanks Lego. That excavator deserves a raise.

[@sanyasiraosenapathi3164]

Very Nice demo of 3 mt Tunnel preparation with preecasted cement blocks with inter locking projections. Regards S S Rao

[@brett8090]

I like the cowboy hardhat with safety duster

[@TriniCrew]

+Brett Brown It's a hard hat, Look at it closely.

[@RCFreaks-channel]

wow this is some smart working ,thmbs up guys ....

[@PatrickCoombe]

truly amazing engineering - any video of the "after" tunnel? was the truck modded in house or did you purchase the roller system somewhere?

[@LockBlockLtd]

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.

[@PatrickCoombe]

Lock Block Ltd. too bad, maybe I'll visit one day :) What a cool technology very impressed!

[@idigau2]

Patrick Coombe I am more impressed by the skill of the backhoe operator. Real smooth.

[@duramirez]

+Lock Block Ltd. Is there a version of it for a wider tunnel, perhaps for a two way tunnel? anyway it's amazing. Congrats !!!

[@สุทัศน์จันทร์ครบ-ฐ1ฌ]

+ หชกยPatrick Coombe

[@saidsaid-pn4yd]

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.

[@terencewilson793]

only a mack can handle the load. love seeing them old mack trucks in action

[@pguiver]

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?

[@sammyspaniel6054]

I would love to build a castle with those.

[@major600]

You need to see the video about the guy who "printed" a small castle using a 3-D concrete printer.

[@matthewmachinist]

yeah the operator knows his machine!

[@pedrochip]

amazing how quick its assembled !

[@ExploringCabinsandMines]

Much much smarter than the first one using chains. you did skip the waterproofing.

[@LockBlockLtd]

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.

[@ExploringCabinsandMines]

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.

[@2012isRonPaul]

i used to do this all the time when i was a kid

[@computeraddic675]

davetileguy Yes,but there is still a hole in the top...

[@JodianGaming]

By about 1:00 I had a serious urge to grab some Lego... LOL

[@DranweRagetotem]

+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

[@JodianGaming]

Absolutely!

[@gearjammer3688]

Now that's what they need under Stonehenge on the 303.

[@simonpender8331]

Very impressive. Very clever.

[@taevue]

10:33, pretty much convinced it's durability when a excavator is on top of it.

[@JCD87]

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.

[@dukeish2003]

kool. would make my underground home an easier thing to create with this kind of tech.

[@riparianlife97701]

I absolutely love this idea.

[@tobiastho9639]

And that's how you built the tunnel to the BATMAN CAVE! Ha ha ha... xD

[@Pr1est0fDoom]

Very nice video!

[@fernaherm]

nice demostration

[@argex]

the escavator driver is awesome tho

[@Mr-Electronist]

Only some wise people could do such a great thing.

[@dman8925]

should put your roller system on hydraulics, lower or raise to help them ease into lock position

[@Mish1035]

Wow!! Great engineering!

[@nscantling]

These guys are just grown up kids playing with legos. :D

[@FirstadsBiz]

Impressive work!

[@tomtaylor8462]

This would be great for robot building systems on other planets. Perhaps the blocks could be insulated for home building. Or that aerated autoclaved concrete

[@mohsinsharif2688]

Excellent work

[@michalhavlicek6521]

My first though was: Oh my, those guys playing with lego...and they paid for it :D

[@johnsmithsitizen8739]

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

[@johnsmithsitizen8739]

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

[@scottphillips7108]

Cross shaped extended connecting points for the arch... Nice choice...

[@JDeWittDIY]

Beautiful tunnel!

[@WhiteTriForce]

: 30 into the video ~ the guy pushing the block with a broom. ~ VERY FUNNY !

[@zombienectar]

guy on the shovel is no slouth. he is what we call an ' operator '.

[@oliverwabwire2836]

Absolutely impressive....

[@andrewwilson8317]

A great product! I assume the Military are well aware of it? Could of sure used its obvious protection ability and speed of installation out in the Gulf and in Afghanistan. Would of saved a lot of lives.

[@s0012823]

Roman building style, I love it!

[@mattbulger9743]

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?

[@abbassamadi6671]

amazing work well done guys

[@pavel1809]

wow very nice i never see that before

[@Mdydaf55]

Awesome! Fantastic! Fascinating!

[@labananiere]

Tecnique de construction très originale, très solide la pelle peut rouler dessus une fois la clé en place. Les blocs de béton peuvent être récupérés en cas de demolition. Vidéo interressante.

[@chkngrl]

I need this done as my root cellar.

[@davidlugo4031]

Wow loved this Video

[@seen203]

This makes me want to build a fallout shelter. Or am I alone in this?

[@KeeperofTheMountain]

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.

[@immortalis1001]

There is something seriously wrong with me...I enjoyed this entirely too much.

[@dy9955]

We need this in the U.S.
