Description

Technical Field

[0001] The utility model relates to a reinforcement bracket, in particular to a temporary reinforcement bracket for a bridge with adaptive control under large-piece transportation working conditions, belonging to the technical field of bridge construction. Background Art

[0002] During bridge construction, due to complex geographical conditions, difficult construction, or tight deadlines, temporary piers are sometimes needed to support the bridge structure and ensure safety and stability during construction. The installation of temporary piers can reduce internal forces during construction and prevent the bridge structure from tipping or deformation during jacking or hoisting.

[0003] However, the existing technology of temporarily adding bridge piers often requires certain modifications to the original structure of the bridge, which will cause a certain degree of damage to the original bridge structure. In addition, the existing bridge reinforcement measures are not temporary and cannot be recycled, and often consume a lot of manpower and material resources. In addition, the existing bridge reinforcement measures are passive structural supports. Under large-scale transportation conditions, they cannot provide real-time monitoring. If the bridge span deflection increases sharply, it is impossible to provide timely warnings and adaptive adjustments.

[0004] In view of this, the present utility model is proposed. Utility Model Content
