Problems solved by technology

[0003] In the past, the deviation correction device was composed of huge and complex machinery such as motors and reducers, and the operating parts tended to be in the middle of the bridge, resulting in low deviation correction accuracy and difficult to control to a "stress-free state" and easily causing safety accidents. Deviation correction device for one-way full cantilever steel truss arch bridge

Abstract

The invention discloses a one-way all-cantilever steel truss arch bridge correcting device and a use method. The correcting device comprises a base. The two ends of the base are each provided with a counter-force base for transversely limiting a steel beam in the construction process and providing stand counter-force during transverse correcting. The two counter-force bases are each connected witha horizontal jack I. The two jacks I are oppositely arranged and used for transverse correcting adjustment of the steel beam in the construction process. A temporary stand is arranged in the middle of the base and used for temporarily supporting a force point of the steel beam. A vertical jack II is arranged between the temporary stand and each jack I. The force exerting end of each jack II facesupward, and the jacks II are used for vertical correcting adjustment of the steel beam in the construction process.

Description

technical field [0001] The invention relates to the installation technology of a steel truss arch bridge, in particular to a deflection correction device for a one-way full cantilever steel truss arch bridge, which belongs to the technical field of bridge construction. Background technique [0002] Foreign steel truss arch bridges started earlier, and their design and construction technology experience is relatively mature. Compared with foreign countries, steel arch bridges started relatively late in China. In recent years, the number of steel arch bridges has been increasing, and experience in design, manufacture, and erection has been accumulated, and research work in all aspects has also made great progress. For example, Dongping Waterway Bridge in Guangzhou, Weiyi Bridge in Liuzhou, Guangxi, Dashengguan Bridge in Nanjing, and Chaotianmen Bridge in Chongqing are all well-known long-span steel truss arch bridges in China. The erection and installation of these bridges ar...
