Shock!More than 7,000 tons of bridges complete the turn!Live video →

Early morning on July 28

Consissed by the 14th Bureau of China Railway

Lanshan Shugang Railway Cross -Qingyan Railway Bridge

Rotary work successfully completed

It marks the country's "Belt and Road"

Rizhao Port supporting project has achieved major breakthroughs

Lay a solid foundation for the project at the end of the year.

The rotary bridge is 131.7 meters in length, 118 meters in length, and a total weight of 7263.7 tons. The method of "first parallel railway bracket is cast -in -law, rear plane turntable", and 58 degrees counterclockwise. The successful completion of the rotation work has created conditions for the follow -up beams, rail paving and four -electricity construction, and laid the foundation for the comprehensive completion of the project.

The

On the morning of March 20, 2020, the construction ceremony of the Rizhao Lanshan Shugang Railway Project held a opening ceremony in Lanshan District, Rizhao City.

The Lanshan Shugang Railway is the first national key railway that is led by the city's planning and approval. It is also a lifeline project of the construction of advanced steel manufacturing bases in our city with a total length of 37.88 kilometers. After the completion of the project, the road network structure of our city will be further improved. Only coal transportation will reduce 700 vehicles per day, which will greatly reduce the logistics costs of Hong Kong enterprises, greatly reduce transportation pollution, and win the blue sky defense war in our city, realize the economy to achieve the economy Social high -quality development provides strong guarantee.

Rizhao Lanshan Shugang Railway Cross -Qingyan Railway is a rare case of cross -high -speed railway on the rare cargo railway in China. Cross -Qingyan Railway Bridge Turning Bridge, a newly built DK8+930.89 of the new Rizhao Lanshan Shuang Railway spans the existing Qingyan Railway. The turning bridge is the highest point across the board. The height of the beam surface exceeds 20 meters. It is rare in China. The beams are large, and the high ratio of the design of the beams of the beams and the high width of the pyrine is the theoretical limit. Form leap.

The foundation of the turn of the body bridge is extremely complicated, the rock surface is 45 degrees, and the infrastructure requirements are high. During the construction process, the project department continued to carry out technical research, repeatedly demonstrated the plan, and made full use of BIM technology to simulate the construction of the rotor. In the process of turning, in order to prevent oversight and super -rotation, the construction dynamic monitoring was performed throughout the process, and a special person at all times observed the angle of the rotor, and the installation of the positioning limit device ensured that the rotation was accurate.
