On December 15, the only turning bridge of the Jiangxi section of the Anjiu Railway-Lushan Extra Large Bridge was successfully turned.
As a key control project for the whole line, the continuous beams of the Lushan Super Bridge cross the west to the west line and the west line, and the angles to the right front of the existing line are 53° and 51° respectively. The weight of a single T structure of the rotation is 5000 tons and 6000 tons .
On the same day, with the order from the site commander, the Lushan Extra Large Bridge swivel bridge rotated counterclockwise at a speed of 1 degree per minute. The on-site staff monitored and monitored in real time according to the scale number, speed sensor and camera arranged on the turntable. Adjust the rotating speed to ensure that the rotating body closes accurately.
"Today's rotation, our horizontal position is controlled at 4 mm, which is far smaller than the tolerance allowed by the specification. It should be said to be very successful and smooth." As the contractor, Hong Ming, the project manager of the Anjiu Railway Division 1, China Railway Fourth Bureau, said. The rotation of the Lushan Super Bridge was successfully implemented, opening up the girder channel of the Anjiu Railway, laying the foundation for the subsequent construction and opening of the ballastless track.
