China rotated a 17,000-ton bridge into place after its construction
Now THAT’S a swing bridge! Chinese engineers build 17,000-ton
flyover section at 90 degrees so railway below could remain open… then
rotate it into place
- Engineers took 90 minutes to swivel the structure into place in Wuhan City today
- The section was built separately so as not to disturb the busy high speed railway track beneath it
- It was the first time the unusual construction technique was used in the country
- China is home to the largest high speed rail network in the World
A 17,000 ton part of an elevated motorway was today slowly swung into place in Wuhan City after being constructed independently beside a high speed railway track.
Engineers took 90minutes to carefully swing the
17,000-ton structure into place today above a high speed railway track
in Wuhan City, central China
A China Railway High-speed train passes beneath
the rotating sector of the bridge today as engineers expertly swivel it
into place
It was the first time the technique had been
used in China, with engineers unable to temporarily halt the busy train
service in order to build the bridge in place
It was the first time the innovative technique had been used in China.
The country has the world's longest high speed rail network with over 6,200 miles of routes in service in December 2012.
The track beneath the bridge in Wuhan City was considered too important to be temporarily halted in order for engineers' to complete construction.
Once finished, the overpass will be 256m long and span 11 railways, including the 1,428 mile-long Beijing-Guangzhou service.
Experts estimate the bridge will be open to traffic later this month.
The 17,000 structure is slowly brought into place in by engineers after weeks of construction
The unusual technique has been used in the UK in the past, though never before in China
The 17,000-ton structure was rotated at 106 degrees on a 15metre axis
The sector is connected to the rest of the
bridge after 90minutes. Officials estimate it will be open to traffic
later this month
A similar technique was used to construct the Grade I listed Kingsgate Bridge across the River Wear in Durham in 1968.
Designed in 1963 by Sir Ove Arup, the bridge's two halves were built on the river's bank and swung together at 90 degrees.
