95.61 degrees, turn, docking!

At 2:18 on June 22, with the Qiqihar Civil Aviation Road cross -line bridge No. 8 pier box beam completed the counterclockwise transition 95.61 degrees, it achieved accurate docking with the No. 7 pier box beam, setting up the largest span and tonnage in my country's severe cold areas. The most heavier concrete continuous beam structure bridge is the highest.

The construction of the main bridge of the project is the "top priority" of the bridge through the bridge. It is located in the southern field of the Ziqihar Railway in the western region of Heilongjiang Province. It crosses 21 existing lines such as the Harzi high -speed rail and the flat electrified railway. Among them, the main span length is 162 meters, the unilateral rotor weighs 27,500 tons, and the total weight of the bilateral rotor is as high as 55,000 tons. It is currently the largest and most heavier concrete continuous beam structure bridge in my country's severe cold areas.

The structure of the rotor beam is composed of the lower platform, the ball hinge, the upper plate, and the rotation traction system. In order to ensure that the bridge completes high -precision rotation, the construction unit has carefully organized the construction plan, conducts three -dimensional modeling and stress analysis of the structure size of the main bridge, and specially optimized the large tonnage transfer support. In the process of turning, it has overcome the disadvantages of poor construction conditions and high risks of high -altitude operations at night, and can be seamlessly connected to key links such as construction organization, process card control, and implementation of responsibility. The box beam has completed a rotor angle of 84.69 degrees clockwise and 95.61 degrees counterclockwise. After turning, the prefabricated beam that was originally parallel to the railway line became a air corridor that spans 21 lines. Essence
