Building tunnels has always been one of the more difficult things humans do on the planet. But a new company just found a way to make it as easy as lego blocks.
Check out this video of a company that found a way to make it as easy as building with really, really heavy Lego blocks.
By using this purpose built “zipper truck” and a little help from gravity, Lock-Block is able to build tunnels in a fraction of the time – and without a 28-day curing period. It’s pretty awesome.
According to the company’s website:
The Arch-Lock™ system offers a modern approach to achieving the high strength, beauty, and durability of an ancient Roman arch, one of the strongest compression structures known to man.
Using the proprietary interlocking system developed exclusively by Lock-Block Ltd., Arch-Lock™ pre-cast concrete voussoirs achieve unparalleled geometric fit and tolerances, eliminating the need for mortar. Arch Lock system Each Arch-Lock™ concrete piece is pre-cured, allowing for rapid assembly and installation. Combined with our state-of-the-art zipper truck assembly process, this reduces construction time by as much as 90%.
You can build at a fraction of the cost and time required for a comparable conventional reinforced post and beam concrete structure. And with no embedded steel to limit the service life, the structure will last indefinitely.
