High-Speed Railway Spherical Hinge 150MN Rotational Spherical Hinge Processing and Installation Construction

With the continuous advancement of science and technology, new techniques for bridge construction without supports have emerged, among which rotational construction is one. Bridge rotational construction refers to a method where the bridge structure is formed (cast or assembled) at a location away from the design axis and then rotated into position. High-Speed Railway Spherical Hinge 150MN Rotational Spherical Hinge Processing and Installation ConstructionIt transforms work above obstacles into on-shore or near-ground operations. Depending on the direction of rotation of the bridge structure, it can be classified into vertical rotational construction, horizontal rotational construction (referred to as vertical rotation and horizontal rotation methods, with the horizontal rotation method further divided into pier-top rotation and pier-base rotation), as well as a combination of horizontal and vertical rotation. Among these, the horizontal rotation method is the most widely used. Bridge rotational construction is suitable for crossing deep valleys, rapid flows, and special river channels that are difficult to hoist.High-Speed Railway Spherical Hinge 150MN Rotational Spherical Hinge Processing and Installation ConstructionIt features cost savings on hoisting, safety, reliability, and good integrity. Recently, an increasing number of bridges crossing railways and highways have begun to adopt rotational construction methods, which do not interfere with normal railway or highway transportation while significantly saving on support materials like timber or steel, ensuring safety, reliability, and reducing construction difficulty.
