Turning bridge with damping function and construction method thereof

Abstract

The invention provides a turning bridge with a damping function. The turning bridge comprises a pile foundation, a bridge pier and a beam body; an upper bearing platform and a lower bearing platform are arranged between the pile foundation and the bridge pier; the centers of the upper bearing platform and the lower bearing platform are connected through a spherical hinge; multiple soft steel dampers are arranged between the upper bearing platform and the lower bearing platform, are positioned on the outer side of the spherical hinge, and are arranged around the peripheral direction of the spherical hinge at equal intervals; multiple support feet are arranged in the peripheral direction of the bottom of the upper bearing platform; and concrete mortar is filled between the bottoms of the support feet and the lower bearing platform. The turning bridge uses a special structure of a turning bridge rotating system to cancel traditional sealing compound concrete construction; the soft steel dampers are arranged between the upper and lower bearing platforms of the turning bridge to achieve higher vertical bearing capacity, and can be cooperated with the support feet and the spherical hingeto support a bridge structure; meanwhile, the soft steel dampers can generate plastic yielding and hysteresis deformation to generate higher damping; and a lot of consumptions enter the earthquake energy of the structure, so that the destruction of the bridge structure is prevented, and the earthquake resistance of the bridge structure is improved.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a swivel bridge with a shock absorbing function and a construction method thereof, which are suitable for bridge engineering in high-intensity earthquake areas. Background technique [0002] The bridge structure plays an important role in the development of the national economy, the promotion of cultural exchanges, and the consolidation of national defense; especially in the event of an earthquake, emergency assistance, post-disaster production recovery, and ensuring the smooth flow of life arteries occupy an important position. Therefore, the importance of earthquake resistance of bridge structures Sex is especially important. [0003] With the implementation of the "eight vertical and eight horizontal" road network of my country's high-speed railway, the construction of expressway and municipal engineering road network will inevitably intersect with the r...
