Abstract

The invention relates to the technical field of bridge pier top swivels, and discloses a large-span V-shaped bridge pier top swivel structure and a construction method, comprising: a main pier cover beam and a support frame, which are arranged between the main pier cover beam and the support frame The hydraulic jack; the outer surface of the support frame is provided with an outer wall connecting layer, and a rotating mechanism is arranged between the outer wall connecting layer and the main pier cover beam, and the rotating mechanism includes a rotating support fixed below the outer wall connecting layer, which is arranged at the bottom The conical rotating part and the heat insulation layer arranged between the conical rotating part and the rotating support, the bottom of the rotating support is provided with an upwardly recessed conical groove, and the conical surface of the conical rotating part is embedded in the conical groove , There is a ball installed between the conical rotating part and the heat insulation layer. The design of the conical surface increases the contact area, which can effectively share the pressure direction and effectively reduce its friction. The array is provided with balls that reduce its friction during rotation.

Description

technical field [0001] The invention relates to the technical field of bridge pier top swivels, in particular to a large-span V-shaped bridge pier top swivel structure and a construction method. Background technique [0002] The swivel construction of bridge pier top refers to the construction method in which the bridge is cast or assembled at the non-design axis position, and then rotated into place through the rotating system set on the pier top. In recent years, with the rapid development of transportation in my country, the construction of overpass bridges is increasing day by day, and the swivel construction of bridge pier tops can minimize the impact on the existing traffic under the bridge, and has been widely used; [0003] In contrast to document CN201920598441.4, the present invention discloses a swivel construction structure at the top of a bridge pier, comprising a swivel main beam, support feet and anchoring devices arranged at the bottom of the beam, a main pie...
