On the evening of June 21, the cross -mortar continuous beams of the cross -mortar high speed (40+72+40) rice constructed by the China Railway Beijing Engineering Bureau. After 90 minutes of rotation of 88 degrees in the air, accurate docking in the air, completing the turning body to complete the body, complete the turnaround body, complete the transfer body, complete the transfer body, complete the transfer body, complete the turning body, and complete the transfer body. It laid a solid foundation for the successful opening of the Golden Yao Railway in 2023.

"Start", 8:30 pm, with a order, the turning construction officially started. Two beams weighing 4,000 tons, under the control of the intelligent operating system, at the same time at a speed of 1 degree per minute, carry out counterclockwise.

"We use the intelligent security system to control the speed of our turntable. In each position, we arranged technical personnel to conduct on -site control to ensure that the rotary beam is safe and correct." Said Geng Qingxiang, chief worker of the 2nd score project of the Golden -Eunuch Railway 5th standard project, said.

It is understood that the Golden Railway across Zhuyong Expressway is located on the highway danger lanes. During the construction of the No. 9 Pier T structure, the vision of the Zhuyong highway danger lanes will be interfered during the construction process. Construction risks, the continuous beams are first constructed along the direction of the highway, and then the dragon is constructed.

90 minutes later, the Trust beams of Pier 8 and No. 9 pier achieve "millimeter -level" docking at both ends. The height error is controlled within 5 mm and the central error is within 2 mm.

Geng Qingxiang, chief worker of the Two Sub -Division of the Golden Yao Railway 5th standard project department, introduced, "This continuous beam is the first largest turntable beam in the Golden -Emperor Railway. The channel lays a solid foundation for the next step and laid the opening of the traffic on October 1st next year. "

The Jinye Railway is an important node project in the economic development of the country's "Belt and Road". It is an important project to implement the national strategy of integrated the development of the Yangtze River Delta and improve the layout of the regional railway network. The convenient transportation between the mainland ports, from Ningbo, can connect the Shanghai -Kunming high -speed rail directly through this railway. In the future, the time from Ningbo to Nanchang, Changsha, Guiyang and even Kunming will be shortened by about an hour. This will further consolidate the position of the Ningbo Railway, and at the same time can condense logistics, flow, passenger flow, and cargo flow, which is of great significance to stimulate the regional economy.
