Background The swivel construction technology is used as an important method in bridge engineering and is widely applied to the scenes of crossing the existing railway, highway or complex terrain. The traditional swivel structure mainly adopts a concrete hinge or a pure steel spherical hinge as a core supporting component, and the working principle is that the rotation of the upper structure is realized by spherical contact. The concrete hinge consists of an upper spherical concrete structure and a lower spherical concrete structure, the spherical curvature is required to be matched accurately during construction, and the pure steel spherical hinge is made of high-strength cast steel and is matched with the spherical surface through machining. In engineering practice, the two traditional hinging forms have obvious technical limitations that the concrete hinge is easy to generate local crushing under the heavy load condition, the friction coefficient of the concrete hinge is as high as 0.15-0.2, so that larger traction force is required when a rotator is caused, and the pure steel spherical hinge generates obvious friction heat in the long-time rotation process although the bearing capacity is improved, so that lubrication failure and even metal adhesion can be caused. With the development of modern bridges in large span and tonnage, in particular the increasing of engineering demands of spans exceeding 200 meters and swivel weights exceeding 3 ten thousand tons, the traditional hinging forms have difficulty in meeting the comprehensive requirements of engineering practice on low friction coefficient, high bearing capacity and stability.
