Abstract

The invention belongs to the technical field of bridge construction, and discloses a bridge resetting support and a bridge resetting method. The bridge resetting support comprises a first bearing platform, a first supporting frame, jacking devices, a lifting device, a suspension device and a horizontal position adjusting device. The first bearing platform is arranged at the bottom end of the pier column, a preset hole penetrating through the first bearing platform in the height direction of the first bearing platform is formed in the middle of the first bearing platform, and the pier column penetrates through the preset hole. The first supporting frames are arranged on the first bearing platform, and the first supporting frames are arranged on the two sides of the pier column. The jacking devices are arranged at the top ends of the first supporting frames. The lifting device is arranged at the top end of the T-beam. The suspension device comprises a joist and a connecting piece, the joist is arranged at the bottom end of the cover beam, the bottom end of the connecting piece is connected with the joist, and the top end penetrates through the T beam to be connected with the lifting device. When the bridge is reset, the pier column and the bent cap do not need to be dismantled and rebuilt, construction cost and safety risks are reduced, working hours are reduced, and the requirement for emergency construction can be better met.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge reset bracket and a bridge reset method. Background technique [0002] Under the complex geological conditions in mountainous areas, the substructure of the bridge is damaged due to geological disasters or other reasons, resulting in the settlement of the pier column, which causes the subsidence of the superstructure and the dangerous situation of subsidence of the superstructure, making the bridge no longer operational. It is urgent to carry out emergency repair construction of the bridge, and at the same time, the environment of the emergency project is harsh , the construction area is limited, which brings great safety risks to the follow-up rescue work. [0003] The current conventional repair method is: erect steel pipe supports first, transfer the load of the superstructure to the steel pipe supports and jack up and reset them, and then dismantle and re...
