Problems solved by technology

It solves the force transmission problem of huge deviation correction force, and at the same time the deviation correction thrust is reduced, but at the same time, it has the disadvantage that it cannot meet the space requirements for installing the reaction force deviation correction device when the space at the top of the pier column is small

Abstract

The invention discloses an annular pre-stress anchoring counter-force rectification device for bridge horizontal rectification, belonging to the technical field of bridge horizontal rectification restoration construction. The device specifically comprises a cross-shaped counter-force rack, a horizontal rectification jack, a leveling steel support, a steering steel support, an annular pre-stressing steel stranding harness, a tensioning jack, a tensioning end anchor and a fixed end anchor, wherein the cross-shaped counter-force rack is anchored on the side face of a pier column through the pre-stressing steel stranding harness; one end of the horizontal rectification jack supports against the upper part of the cross-shaped counter-force rack, and the other end of the horizontal rectification jack pushes against a main beam of the bridge, so that rectification restoration can be realized. The annular pre-stress anchoring counter-force rectification device has the advantages of simple and light structure, economical construction cost, convenience in assembly and standard construction, short construction period, slight influence on structure stress and high combination degree with structure characteristics of bridge piers, and is not influenced by the mounting space of pier top.

Description

technical field [0001] The invention relates to the technical field of bridge horizontal deviation rectification and reset construction, in particular to a circumferential prestressed anchoring reaction force deviation rectification device for bridge horizontal deviation rectification. Background technique [0002] At present, two methods are used to set up the rectifying device for rectifying the deviation of bridges. The first method is to set the rectifying force foundation and the large rectifying and reacting force supporting frame around the pier column. For example, Chinese patent CN104947606A discloses a rectifying method for the upper structure of the bridge. , on the bridge pier, a steel-column girder is installed, the steel-column beam is fixed to the pier by bolts, and the steel-column beams are connected as a whole with supports, which solves the limitation of the jacking operation due to the lack of space between the pier and the bridge, and reduces the bridge s...
