Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a hoop mounting frame structure on a bridge pier with complex terrain. Background Art

[0002] When building a bridge between general bridge piers, the common method is to use pre-installed bridge modules to build it directly between the two piers; however, for complex terrain and curved locations, the common method is generally to use a cast-in-place method. This cast-in-place bridge requires the construction of a Bailey frame to support the concrete casting mold, and the Bailey frame is supported by a scaffolding. However, this method is generally suitable for flat ground and low-height piers. In complex terrain, it is impossible to set up a scaffolding to support the Bailey frame, which requires a bracket structure to support the Bailey frame on the cast bridge support pier; the installation of the common bracket structure requires the use of a crane for lifting and manual operation on the boom. This method is costly, and the crane needs to be used for a long time, and the turnover efficiency is low. Therefore, a new mounting frame structure is needed to achieve the installation of bridge pier brackets, which is difficult to install with a crane in complex terrain. Utility Model Content
