Record Breaking Bridge Demolition – VIDEO
Built in 1997, the Zhuan-yang viaduct, which is located in southwest Wuhan, capital of central China’s Hubei Province, used to be an important part of China’s National Highway 318 (G318) running from Shanghai to Tibet and is to be replaced by a 6-lane, 5.1-kilometer long viaduct as its design capacity is far below what needed.
It is the most difficult demolition ever undertaken in China for it is closely surrounded by residential buildings, and runs along 100,000-volt wires, over 30 underground pipelines including the main pipeline transmitting natural gas from west to east China.
“As the environment is very complicated, we have adopted very strict protective measures. For example, we put water bags along the viaduct to reduce the dust produced in the process of demolition. The water mist produced in the blast can absorb the dust,” said Xie Xianqi, president of Wuhan Demolition Engineering Company.
