See how a tunnel can be built in record time with the aid of this truck

Modern technology is already present in every field of activity, especially when the pace of construction has to be fairly brisk. Building a tunnel usually involves both human and mechanical powers and considerable time – but the demonstration in the video proves the contrary.

The “Zipper Truck” built by Lock-Block Ltd. is the main tool in digging a tunnel in less than an hour. At first, an excavator digs in deep where the tunnel will be located below ground level. The first step is the placement of the concrete blocks that form the base, followed by the placement of the components for the arch of the tunnel.

Here comes in the miracle truck, which has in the back an arch with rollers over the entire length of the trailer. The concrete blocks used to construct the tunnel are like Lego pieces that fit together perfectly without any bonding material. Along with the use of the excavator, filling soil is compacted around the tunnel.

The truck slowly moves forward, and little by little the tunnel begins to take shape. The construction workers ensure the perfect laying of the concrete blocks, and the cup of the excavator, handled skillfully, better secures them.

When everything is ready, the truck crosses the tunnel to settle the blocks and drop them in the perfect position, and also to verify the resistance of the work. It is impressive how in such a short time, with the aid of seemingly simple technology, a large and impressive infrastructure project can be finished.

The tunnels are not the only self-supporting structures that can be created using this quick and efficient method. Highways, subways and the arches of underground constructions can also be assembled using the Zipper Truck. Another unique feature is that when a structure of this kind is no longer needed, the blocks can be disassembled and reused in another project.
