Revolutionizing High-Speed Railway Bridge Construction: The Rotational Construction Method

🔄The rotational construction method revolutionizes the building of high-speed railway bridges, allowing for efficient and precise assembly.

🚄Mechanical equipment such as hydraulic jacks and support frames are crucial for the success of the rotational construction method.

🌉The method involves dividing the bridge structure into axial and movable ends, with the movable end being repositioned using mechanical equipment.

🏗️The rotational construction method follows a meticulously planned sequence, including track beam support frame erection, track beam installation, main beam hoisting, beam rotation, and closure, and removal of temporary facilities.

🇹🇼The rotational construction method was successfully applied in the National Highway Number One Woo to Yang May section widening project in Taiwan, demonstrating its effectiveness in challenging construction contexts.

What is the rotational construction method?

—The rotational construction method is an innovative approach to bridge construction that involves dividing the bridge structure into axial and movable ends. The movable end can be repositioned using mechanical equipment, allowing for efficient and precise assembly.

What mechanical equipment is used in the rotational construction method?
