Zipper truck can build a tunnel in 24 hours

Clearly, this isn’t your regular truck. It’s a custom build that allows masons to erect free-standing tunnels very fast. The roller-covered arched rear temporarily supports the Lego-like brick structures, which are then locked in place without the need for an adhesive.

The truck was custom built by Lock Block Ltd. According to the company, the Zipper truck can help make a quarter mile archway in less than 24 hours.

The specially designed building blocks with interlocking pegs are held by the arched-rollers of the truck, functioning as a frame. The truck is tapered, with the front arch being taller than the tail. As the truck moves forward, the blocks fall and compress. This is very similar to how a zipper works, hence the name.

Using this technique engineers can built highway and railway over/underpasses, tunnels, hurricane/tornado shelters, wine cellars, culverts, ditches, and creek crossings very fast. There’s no need to wait for the typical 28 days of the curing process and a tunnel can be serviced immediately. Moreover, the pegs can be removed and re-used.
