AI Technical Summary
During the bridge correction construction, the space on the top of the single-column pier is limited, and it is impossible to set up a device that can serve as both a correction reaction frame and a limiting function. In addition, the original bridge needs to be kept open to traffic during the construction process, and the existing limiting facilities cannot meet the needs.
A bridge deviation correction and lateral limit safety device is designed, which includes a pier and a beam. By arranging components such as anchor rods, corbels, positioning steel plates and nuts on the pier and the beam, an adjustable connection structure is formed, which can provide both deviation correction reaction force and limit position, and a protective layer is applied on the outer side of the corbel to enhance durability.
It realizes the protection of beam deviation during the correction process, and the lateral displacement can be directly detected in the later stage, avoiding complicated monitoring layout, enhancing the corrosion resistance and wear resistance of the device, and extending its service life.

Technical Field
[0001] The utility model relates to the technical field of bridge reinforcement, in particular to a bridge deviation correction and transverse limiting safety device. Background Art
[0002] Currently, some curved box-girder bridges designed and constructed earlier use a single-column pier and hanging beam structure. Over time, due to the effects of temperature and centrifugal force, these structures are prone to excessive bearing slippage, pier tilt, and beam offset, posing significant safety risks. Consequently, corrective construction is required.
[0003] However, during the correction construction process, the corresponding supports need to be released, making the longitudinal and transverse limits of the original bridge invalid. In similar construction processes, the original bridge often needs to be kept open to traffic, and thus a limiting safety facility is needed. However, the space on the top of the single-column pier is limited. After the reaction frame is installed, there is no space to set up a limit device separately. Therefore, it is necessary to provide a device that can be used as a correction reaction frame and also play a limiting role during the process of pier correction and beam resetting. For this reason, we propose a bridge correction transverse limit safety device. Utility Model Content
