Xinhua News Agency, Beijing, November 7 (Qi Zhongxi and Ye Tingyong), a reporter learned from China Railway Construction Corporation that on the afternoon of the 7th, the Xincheng (Metro) Kunming (Ming) Railway Longchuan River Third Line Bridge, constructed by the 11th Bureau of China Railway, successfully completed the pier. Transit. This construction set a world record for the construction of a railway bridge pier with a turning height of 41.4 meters and a single weight of 7350 tons.
According to Liu Zubin, project manager of China Railway 11th Bureau, the Longchuan River Third Line Bridge is located in Chuxiong Prefecture, Yunnan Province, with a total length of 460.8 meters. Because the bridge will cross the existing Chengdu-Kunming Railway, the risk of safe construction is high. In order to reduce the impact of construction on the existing Chengdu-Kunming Railway traffic safety, the builders first poured large bridge bodies on both sides of the Chengdu-Kunming Line, and then bridged the bridge surface by turning the pier.
Xincheng-Kunming Railway is an important high-capacity corridor in Southwest and Northwest China. It is designed as a first-class double-track electrified railway with a passenger train design speed of 160 kilometers per hour. After the completion of the whole line, the passenger and cargo transportation capacity in the southwest region will be greatly improved.
