Recently, the West Extension High-speed Railway across the Xixian North Ring Line Bridge has been successfully turned to achieve precise docking in the air. Located in Gaoling District, Xi'an City, the overpass bridge across the Xixian North Ring Road is constructed by the 11th Bureau of China Railway, with a total length of about 4,833 meters, which is a major and difficult control project of the whole line.
During the rotation process, the two 10,000-ton continuous beams began to rotate synchronously at an altitude of 15 meters above the ground, which lasted 50 minutes, and then turned 66 degrees counterclockwise respectively and then crossed the Xixian North Ring Road and was accurately in place.
