Let the bridge achieve a nearly 90-degree "turn"? Engineer Liu Owim did it!

June 29，Heze City Changjiang Road Expressway Crossing Beijing-Kowloon、Xinli Railway Overpass SucceededFinish nearly 90 degrees.“Turn around magnificently”，Precise docking between the north-south double-width swivel bridge and the main bridge，It marks the most critical step of the Yangtze River Road Expressway Project.，Lay a solid foundation for the next step of opening the Yangtze River Road Expressway。

Liugong Owim Company provided professional construction technology for the swivel construction.，Independent research and development of large tonnage swivel equipment，It is also responsible for the installation of swivel equipment.、Debugging、Important work such as operation and rotation operation。

Crossing Beijing-Kowloon on Changjiang Road Expressway、Xinli Railway Overpass is 199 meters long.，It is divided into two parts, north and south, across Beijing and Kowloon.、Xinli Railway，The swivel bridge is adoptedTDesign of double-width simultaneous rotation，Separate pouring along both sides of the railway、Turn at the same time，17 per width.5 meters。Swivel length: 162m，The total weight of the two swivel bridges is about 50,000 tons.，The north main bridge rotates 90 degrees counterclockwise.，The south main bridge rotates 82 degrees clockwise.。The bridge is the largest swivel bridge across the highway and railway in the southwest of Shandong Province.，It is also the first cross-railway swivel bridge with double swivel mode in Heze City.。

The project is close to the main railway line.，High density of train operation，Skylight operation time is limited，In order to minimize the impact of construction on the existing railway,、Disturbance of road operation，The bridge adopts the design scheme of beam support cast-in-place and swivel.。In order to make the project go smoothly，Technical R & D Team of Liugong Owim Company Overcomes Difficulties，SuccessivelyMain control system for large-tonnage swivel、The control system of hydraulic pump station and continuous Jack are upgraded intelligently.，Pull the equipment、The force is uniform、Synchronous Control、Precise positioning，Ensure the swivel project“You can turn”“Turn steadily”“Turn accurately”。

The construction process of bridge rotation is complex.、Difficult、High risk and other characteristics，Liugong Owim will continue to optimize and upgrade the relevant construction technology.。As a leading enterprise in the prestressing industry，Liugong Owim will continue to promote innovation-driven development，Continuously improve the core competitiveness of special equipment，Deep ploughing of prestressed industry，To speed up construction“A manufacturing power、A transportation power”Make a greater contribution。
