Abstract

The invention relates to a temporary buttress anchoring system of a continuous beam bridge and a construction method of the system, and relates to the field of bridge engineering construction. The temporary buttress anchoring system comprises stand columns, temporary supports and prestressed tendon assemblies. One end of each stand column is fixed on a bearing platform; each temporary support comprises a first temporary support block and a second temporary support block which are arranged from bottom to top; one end of the first temporary support block is fixed with one end of the stand columnaway from the bearing platform; the end, away from the first temporary supporting block, of the second temporary supporting block is used for being fixed to the bottom of a main beam, the prestressedtendon assembly is used for penetrating into the main beam, one end of each prestressed tendon assembly is used for being fixed to the main beam, and the other end of each prestressed tendon assemblyis used for being fixed to the end, away from the bearing platform, of the corresponding stand column. According to the temporary buttress anchoring system and the construction method thereof provided by the invention, the problems of unclear stress, low anchoring efficiency and narrow application range of the temporary buttress anchoring system during temporary solidification of a pier beam of continuous beams in related technologies are solved.

Description

technical field [0001] The application relates to the field of bridge engineering construction, in particular to a temporary pier anchorage system of a continuous girder bridge and a construction method thereof. Background technique [0002] At present, in order to solve the problem of unbalanced moment / overturning moment during the cantilever construction of the main girder of the continuous girder bridge, the method of setting temporary column brackets next to the pier or setting temporary supports on the top of the pier is usually used in engineering. [0003] In related technologies, the structural form of setting up temporary column brackets next to the piers usually adopts the combination of steel pipe concrete columns supported on the caps and brackets. The brackets bear the self-weight of the main beam structure and the vertical load during construction, and transmit For the lower concrete-filled steel pipe column. The temporary support for pier beam consolidation i...
