19 buildings in Wuhan blown up in the blink of an eye

Monday, 23 January 2017

19 buildings disappeared in the space of 10 seconds after being demolished by a controlled explosion in China yesterday.

The blocks of flats, which were up to 12 storeys high, in the city of Wuhan are making way for a huge new business district, including a 707-metre tall skyscraper.

Experts waited until dark had fallen before detonating demolition charges which brought down 150,000 square metres of concrete, glass and steel in 10 seconds.

The residents of the Hankou Binjiang estate had been moved out weeks before.

The area is close to the city centre and the demolition contractors had to make sure that when they brought down the buildings they did not damage a light rail viaduct nearby or a shopping mall and electricity sub-station.

Jia Yongsheng, general director of the demolition company, told China’s state TV channel CCTV: ‘For this kind of large-scale blasting demolition conducted in the downtown area, we not only need to guarantee the demolition result, but also strictly control the adverse effects of blasting.’

5 tons of explosives were spread around 120,000 locations in the buildings and the timing of each detonation was set to within a few microseconds.

Wang Xuguang, an expert at the Chinese Academy of Engineering, said it was the first time the implosion technique had been used in China and it saved the construction company 4 months.
