Embodiment Construction

[0034] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0035] An anti-climbing and overturning device for a curved girder bridge, comprising a first steel plate (1), a second steel plate (2), a third steel plate group (3), a fourth steel plate (4), a fifth steel plate group (5), a girder Embedded steel plate in body (6), embedded steel plate in pier (7), nut (8), embedded bolt (9), curved beam bridge body (10), pier abutment or pier cap (11), piston assembly (12 ), rubber layer (13), wedge block (14), friction plate (15) between wedge block and the fifth steel plate group, limit screw rod (16), limit nut (17), sensor (18).

[0036]There is a pre-embedded steel plate (6) inside the curved girder bridge body (10), and the upper steel plate group members are connected outside the beam body by the e...

Abstract

The invention relates to a curved beam bridge anti-creeping and anti-overturning device and a construction method. A beam body internal embedded steel plate is arranged in a curved beam bridge body, an upper steel plate group component is arranged at the lower end of the curved beam bridge body, the embedded steel plate and the upper steel plate group component are fixed through embedded bolts and nuts, and the piston assembly is bonded with a third steel plate group, a first steel plate and a fourth steel plate; a pier inner embedded steel plate is arranged in a pier abutment or a pier cap of the curved beam bridge pier, and a lower steel plate group component is arranged on the upper portion of the pier abutment or the pier cap of the curved beam bridge pier. and the upper steel plate group component is connected with the lower steel plate group component through a wedge block. By means of the device installed through the device, accumulated residual displacement when horizontal lateral movement happens to the curve beam bridge can be effectively reduced, the creepage disaster of the curve beam bridge is prevented, meanwhile, the anti-overturning capacity of the curve beam bridge can be improved, and the possibility that the curve beam bridge overturns and is damaged is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to an anti-climbing and overturning device and a construction method of a curved girder bridge. Background technique [0002] With the continuous improvement of my country's comprehensive strength and economic level, the transportation industry has developed vigorously, and the development of road and bridge construction has entered a new height. At the same time, the demand for transportation has also been greatly improved with the improvement of people's living standards. . In order to meet the increasing traffic volume, many new highways and urban bridges have been newly built in my country in recent years, especially many urban overpasses and viaducts have been newly built, which has greatly improved the urban traffic conditions and made the urban traffic system move towards a three-dimensional Growing. [0003] Curved girder bridges are favored by many ur...
