[0002] Temporary support structures for bridge construction are an indispensable equipment in the bridge construction process. They can provide solid support to ensure the safety of workers and effectively protect the structure of the bridge. These support structures play a vital role during construction to prevent accidents such as earth collapse and sliding, and ensure the safety of the construction site.

[0003] The temporary support structure for bridge construction disclosed in the Chinese utility model patent application disclosure CN218712213U calibrates the position by adjusting the steel box girder using multiple jacks. Multiple jacks are evenly distributed under the steel box girder and the jacks are operated according to demand, making the calibration efficiency of the steel box girder higher. At the same time, limit angle steels are installed on both sides to limit the range of movement of the steel box girder to a certain range, so that the installation of the steel box girder is limited to a certain range of movement, and the efficiency of the segmented positioning and installation of the steel box girder can be significantly improved. However, the temporary support structure has low functionality and cannot stably support the bridge workpiece for construction conditions of different terrains and ground, resulting in poor use of the support structure and certain safety hazards.
