On 13 november, the chinese news agency nanchang (journalist wang sword), technicians discovered a crack on the bridge on the yangtze bridge road, which was partially closed by the bridge administration and limited to vehicles of less than 20 tons. On the evening of the 13th, china news agency reporter received an update from the transport department of jiangxi province and, after an initial “medical examination”, no similar cracks have been found on the other parts of the yangtze bridge road, without affecting the structural security of the bridge and the safety of railway operations。
On 11 november, at 1730 hours, when construction technicians at the nine river yangtze river bridge carried out a steel beam maintenance test, it was reported that a horizontal breach had been found in section 12, section 3, of the fourth collapse of the bridge, which affected the safety of the bridge, and that the authority had immediately initiated an emergency response plan, partially closed the areas at risk, restricted the movement of vehicles under 20 tons and diverted more than 20 tons of vehicles。
In response to this crack, on 12 november, the nine yangtze bridge authority carried out a comprehensive survey and testing of the bridge. Following an initial “medical check-up”, no similar cracks have been found on the other parts of the nine river yangtze bridge road, without prejudice to the structural and operational security of the bridge。
It is understood that the bridge authority has commissioned the design of the iron bridge in order to develop a reinforcement programme for the cracks in the steel beam, which will be completed on 14 november. The transport department of jiangxi province will, on the evening of the 14th day, invite national experts on roads, bridges, railways and steel beams to review the reinforcement programme and report it to the jiangxi department of transport and communications for approval and for immediate construction once approved。
It was also explained that, as a result of the timely notification of the closure, the nine river yangtze bridge had so far been restricted and had not experienced widespread congestion。
On the evening of the 13th, china news agency journalist learned from the maritime department of kyushu that, as a result of the recent maintenance of the bridge, all vehicles carrying more than 20 tons were prohibited from entering the bridge, and that most of the vans had been diverted to cross the river by means of trans-cruising。
The bridge is located on the border between the provinces of jiangxi, hubei and anhui, and is located on the yangtze river, which is wide with huangmei. The bridge was completed in january 1993. The railway bridge is 7675 metres long, the road bridge is 4460 metres long, and the design and construction of the nine river yangtze bridge contains 11 scientific and technological achievements, updating the national and international record of bridge construction.
