Experimental movie of ultra-rugged protective wall that can withstand direct truck hits

The outer wall of an American nuclear power plant can bear even a crash of fighter aircraftIt's a pretty famous story,British Information Bureau Security Division, This protection wall developed to protect the facility of so-called MI 5 is also quite good. I brilliantly endured the 7.5 ton truck clash that ran at 40 mph (approximately 64 kph).

Details are below.
MI 5 develop barrier than can stop suicide truck at 40 mph | The Sun | News

This barrier made from Steel made by Steel Corp., which was acquired by Tata Steel in 2007, is 230 pounds per meter (about 30,000 yen). It is designed to be able to be stopped up to 20 miles per hour (about 32 kilometers per hour) for 30 ton heavy duty trucks and 90 mphs per hour for ordinary cars (about 150 kilometers per hour). Concrete is filled between steel materials at a thickness of 2 feet (61 cm) and a height of 3 feet (about 1 meter), and only 6 inches (about 15 cm) is buried in the ground, but a superb track I am taking it.

Let's see the video in the source article. In the experiment, we pulled a 7.5-ton truck with a cable and hit it against a defensive wall at a speed of 40 miles per hour (about 64 kilometers per hour).


Impact moment


Entire vehicle collapses but still does not lose kinetic energy and keeps moving


But the wall does not move at all and the truck coming in a little obliquely slides sideways while scattering the luggage


A truck that skips the roof and continues to slide on rolling while falling apart


However, the wall lives a little scratched


Although it is said to be a protective wall, it is not used as the exterior wall of the building, but by surrounding the building's surroundings it is used to keep vehicles carrying explosives from approaching buildings even if they rush. It is speculated that it will be used for buildings of MI 5, the Ministry of Defense and Buckingham Palace.
