There are many differences between our system and the monolithic domes you describe. They are one piece and are structurally much different. Having natural joints in the structure means the forces that travel through it are much different. Also, since our system is modular, it does not require rebar reinforcement. They are also pre-cast, meaning they can be installed very quickly and de-constructed and re-used if needed.

With an operator, me and my buddy built a 25 foot wall on a 6 degree angle on the vertical and were able to curve it roughly an inch per block. It was an "S" shape and was for a storage facility on the Sunshine coast. These blocks are AWESOME!!! Of course every second layer of block needed geo-grid for strength. And an engineer and proper permits. What fun!! Will be there my lifetime! Good times!

I can just imagine these guys singing "Everything is Awesome!" while they build this stuff. lol

You both are so funny! LOVE this arched block technique and want to try it here in Guatemala... fabulous construction!

It's a stormwater retention vault. The blocks are solid concrete with galvanized steel lifting hooks.

Part of the reason the Roman designs last so long is because of the arch shape itself. Since everything is in compression, the concrete is used to its maximum capabilities. As you might know, concrete is much weaker in tension than it is in compression. If you're interested in alternate methods of constructing these arches, subscribe because we'll be showcasing it later this week.

Very fascinating and interesting to watch. It leaves your mind in total amazement when you think about the Aqueducts arches that were built by the Romans over 2000 years ago.

This is really some great building! Nice!

Thank you for your comment. The chains are rated to carry many times the weight of the block. There is absolutely no risk of them snapping.

Terrific video... Here I am back, 4 years later, forgot I even saw this. Still want to try it!

The compacted soil added at the end to cover it acts as the lateral stabilization and ensures that the arches will always be in compression.

We made an underground water settling pond with 3 chambers. The entire thing was then paved over.

@awwwsnaps Indeed it's a classic roman arch. The internal steel cables that run through it are merely for safety during construction and to make it easier.

What amazes me is that ancient people were building the exact same concept even through the middle ages with just hand tools and raw manpower!

I think they must have had some kind of levitation back then or some kind of way to lift and move that we no longer have today so we have to invent machinery to do it now that they didn't need back then.

It's a wonderful building!

That's just beautiful.

That's some impressive building techniques.

If one were to make a poured in place arch, it would actually be weaker because the entire structure would be one piece instead of discretized into segments. The fact that the arch isn't a solid piece means that the load calculations on it are different. A piece-wise arch is better suited to handle the loads and far cheaper than a rebar reinforced one. Please contact us via our website to discuss pricing.

everything is awesome!

The structure was designed by an engineer to withstand earthquakes just fine. After the arches were finished being put together, soil was dumped on top which restricts lateral movement. For an arch to fail, 3 hinge points have to open up. Since it's back-filled, there's no chance of that happening.

This is a very strong construction. No metal to rust and no concrete joints to crack with freeze-thaw cycles. It will probably outlast most buildings in the area.

Nothing but love here. Time to cook.

Well...we learn something new each day:) I was thinking that might be but, thanx for clarifying! Its interesting and a good place to watch the fingers:)

It all depends on the capabilities of the crew placing them and the accessibility of the site. United Lock Block Ltd. is currently working on making arch creation easier.

If you visit our website and navigate to the "retaining walls" tab, you can scroll down and see our various finishes. The Vertical Rib finish is very good for dissipating sound and that finish could be applied to the inside of an arch.

Fantastic...one step at a time..

Yes and we have. Please see this picture taken in the 80's outside the Empress Hotel in Victoria, BC. Link is added to description.

I really want to make my house out of these.

In addition, the arches you see here were buried after installation and are constantly driven over by mixer trucks. The domes you describe would shatter if a fleet of trucks were parked on top of it.

@MillyVanillification Only for this method of construction. You can also make a mold of the arch underneath to support the blocks. That's what the Romans did.

Thank you for your marketing suggestion! =)

Good Work...

Beautiful and smart blocking. :) I like how you leave more space before the final lock so that the side plugs fit into sockets. What must be the average weight of each block?

Fascinating, humans are amazing.

What a machine Driver& what a great system 👍

The structure is as amazing as it is creepy.

moc pěkná práce čoveče

That's cool how they have to put slack in the chains when applying the center piece in order for gravity to hold it.. Physics is amazing

Really nice

Since the entire structure is engineered to be in compression, there is no need for mortar between the joints. The joints CAN be sealed if needed though.

If I could use the original Roman technology I would use that. It would last thousands of years and it wouldn't require such expensive tools. A great example of technological involution.

Very true but those require a lot of reinforcement. These blocks are just solid concrete.

big Legos!

@SuperNorthAmerica They're concrete without rebar. Since the entire arch is in compression, there's no need for reinforcement.

Well if this one sends a shiver up your spine, you should check out our other arch construction video!

I swear i want a house builded like this now please :)

To construct an arch with formwork would take much longer and require specialized labourers to build. Creating the custom formwork for a pour in place job would also be very expensive and not re-usable as wood is typically used. In addition, the engineering of a structure that is poured in one piece is completely different and far inferior than individual blocks. Building the arch from pre-cast pieces is also quite a bit faster. In short: Less time, cheaper labour, cheaper materials.

Lock Block Ltd, This video seem to be a good one, but can u show us the finale result when the job /project was finished , just to show this arches what they are used for ? ( I trying to understand what was the purpose of all this job at the end of the day ). Thank u

It's a little more complex because it has to be engineered to last for 75 years or more and handle industrial traffic driving over it. I'd like to see lego do that ;)

So do you guys use those chains to hold the blocks in place when the space your working in is too small for the truck?

They already build bridges with pre-formed concrete blocks, manufactured off-site and delivered ready to be installed, the crane required is bigger but you save in time and labour and follow on trades.

Cool Stuff.

I want my bug-out bunker built of this stuff. It looks like it would be incredibly strong, fairly quick and easy to install, and last a good long time. Certainly outlast me and a generation or two, anyway.

@sain0777 No problem, but you would still have to have an engineer run through the design to be sure.

Make a metal "arch shaped" beam that you can attach 8 blocks to, then raise the whole beam with pre-formed arch and drop on top of footings, disconnect the beam... reckon that would saves loads of time!

The advantage of using the Arch-lock system is that it is much faster and cheaper to construct than a structure made with conventional techniques.

man i would totally build a lock block castle with 40 ft walls and a draw bridge !!!

Increíble y peligroso....muy bueno

doomsday preppers on a large scale

That's still a massive amount of concrete for the usable floor space created... And what happens in a Seismic event... One lost block and it de-engineers itself...

what are they building ?,i love the simple construction this system offers.

What is the maximum arch width you can span so far? ie a 30 foot span. Can you precast utility runs in the blocks? For electric lines and such. Would this system be adaptable to utilize foamcrete or equivalent? A super light concrete building material. Very impressive system.

Always remember your childhood, so you can grow up and make a fortune with 1/2 ton legos made of concrete.

Interesting. The sarsen stones in stonehenge have pegs and sockets.

good job from Egyp

How much weight can those things handle on top when done? awesome.

Aaaaawsome!!

much better design than the open mosquito breeding ponds on most sites.

I think you'll have to talk to the people over at Merriam Webster for that!

Water reservoir for rain runoff under parking lot. Said somewhere above in a different comment thread.

1:34 he was like damn!.......f*** it. Its level for me! :) But for this arch they could have build a frame from steel that you can adjust and lower when the headstone is in place. Then move the frame again. No chains needed. Of course the frame needs to be higher then the arch in order the get the headstone in. But the chains work pretty fast and every project is different. And chains work saver...you do not have to get under it in order to lower the frame. The frame needs to be standardized in order to let it work profitable and make it useful for different projects. Respect your work! I learned from it as a student construction engineer.

The blocks sure do fit together nicely. I assume that the stored water is used for some purpose? Pete

Saves a lot of bricks and bricklaying work, that is for sure. But what are these tunnels for at all? Seems there is no connection at the end.

Can you make the world's large maze and charge people to get lost in it ? or have a marathon race ? Or a rollercoaster in the dark ? or a giant bat cave ? or a subway ?

So the structure is supported by itself, using the compression of its own weight? Wouldn't it 'wobble' if there's an earthquake or construction nearby. They can't use this method for larger span or arc right?

@LockBlockLtd

10 жыл бұрын

When the structure is backfilled (covered with dirt, in this case), it's not going to wobble anywhere. If you wanted to build a free standing arch, you'd want to secure its outside radius with a steel cable to keep it sturdy while in motion. Or, you could thread it through the inside of the arch through a pre-cast conduit.

Couldn't have been easier if they were coated in KY... lol this guy

Thats really cool! Play with Lego is a experience requirement for job applications?

@fightapathy416 No we have not, but it is completely feasible

Great job for sure! But why would someone need a structure like that? Why not a regular concrete underground garage type structure?
