Super-huge 0 # block cast-in-place box girder bracket structure and mounting method thereof

Abstract

The invention relates to the technical field of road and bridge construction, in particular to a super-huge 0 # block cast-in-place box girder bracket structure and a mounting method thereof. 2, pier body embedded parts are installed; 3, the brackets are assembled according to the assembling sequence; 4, the steel cable is tensioned; 5, a formwork is installed; step 6, carrying out bracket prepressing detection; step 7, 0 # box girder construction; compared with a traditional triangular bracket, the bridge bracket structure does not affect the navigation and passing requirements of the lower portion of a bridge span; the structure is more stable, the wind load can be resisted, the construction safety risk is reduced while the structure safety is guaranteed, and the device can well adapt to the construction of various large 0 # block cast-in-place box girders and is safe, reliable and convenient to construct. When the bracket is installed, a large number of tailor-welding procedures are not needed, the assembly efficiency is high, rapid installation and disassembly can be achieved, the overall construction period can be effectively shortened, the turnover utilization rate of materials is increased, and the bracket has wide application and popularization value.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to an extra-large 0# block cast-in-place box girder bracket structure and an installation method thereof. Background technique [0002] As the scale of road and bridge construction increases, large-scale continuous bridge construction projects are also more common. Compared with ordinary bridge engineering construction, the construction of large continuous bridges is more difficult, more complex, and more strict in technical requirements. Because the cast-in-place box girder 0# block is heavy and has poor safety, its construction technology is difficult, it is inconvenient to apply large-scale machinery, and it is also easily affected by factors such as climate and geological conditions. Therefore, the construction of the cast-in-place box beam block 0# is guaranteed. Quality is a very critical aspect. [0003] At present, the construction method of block 0# o...
