On April 20, the Jinan Uplink and Downlink (64+64)m T-structure swivel bridge of the Jinan-Zheng Railway constructed by the China Railway Tenth Bureau slowly rotated in the same direction, and the swivel was precisely in place within 100 minutes. The Beijing) Shanghai (Shanghai) line and the Shui (Shuitun) and Bai (Bai Mashan) lines have achieved leaps at the same time.
This is the first swivel bridge project to achieve a successful double turn in the Jizheng railway project, laying a good foundation for the opening of the track laying channel in the Shandong section of the Jizheng railway.
This swivel bridge is the newly built Jinan-Zheng Railway Jinan Up and Down Link Line Extra Large Bridge. It is a T-shaped rigid frame bridge with double width and variable beam height, with different swivel angles and different swivel speeds. The swivel structure consists of a lower turntable, a spherical joint, a It consists of an upper turntable and a swivel traction system. The length of the swivel is 128m, and the weight of a single swivel is 6500t.
The swivel process adopts the construction mode of "build first and then turn", that is, first build in parallel with the existing railway, and then swivel to connect with the bridge piers on both sides.
Jizheng High-speed Railway is a high-speed railway trunk line planned and constructed by Shandong Province and Henan Province. It starts from Zhengzhou East Station and ends at Jinan West Station. An important part of the high-speed rail network strategy.
The main line of the Shandong section of the Jizheng Railway is 170 kilometers long and has 5 stations, namely Jinan West Station, Changqing Station, Chiping South Station, Liaocheng West Station and Xinxian Station.
After the project is completed, the time-space distance from Jinan to Zhengzhou will be shortened to 1.5 hours.
