[0002] The long-span steel-concrete composite box girder bridge has experienced decades of development, especially since the 1980s, European countries have done a lot of work in the research, design and construction of steel-concrete composite box girders. With the deepening of basic theoretical research and the advancement of design theory and design methods, a large number of highway and railway long-span composite box girder continuous girder bridges have been built, which concentrate on new research results, new design methods and new construction processes.

[0003] For example, an ultra-wide and large-span composite beam bridge and its construction process with the authorization announcement number CN202410327942.4 and the authorization announcement date 20240709, the composite beam bridge includes a foundation, two side piers, two middle piers and a steel-concrete composite beam, and the steel-concrete composite beam is composed of a steel main beam, a UHPC bridge deck and concrete; the construction process steps of the composite beam bridge are as follows: construct a foundation, side piers, middle piers, temporary piers and loose-assembled supports; splice the steel main beam on the temporary piers and the loose-assembled supports, and after the steel main beam is constructed to the joint section, pour the steel beam bottom plate combined with concrete at the middle pier support; remove the loose-assembled supports, apply pre-loading force to the top of the temporary pier, adjust the steel beam line shape, and install the mid-span joint section; pour the UHPC bridge deck at the middle of the main span and the end of the side span beam, and remove the temporary piers; pour the remaining UHPC bridge deck from the middle of the span and the end of the side span beam to the middle pier respectively; and construct the ancillary construction of the entire bridge. The composite beam bridge of the present invention is applicable to a span of more than 200 m, which improves the utilization efficiency of the bridge and makes the beam bridge structure more beautiful, thereby promoting the development of ultra-wide and large-span composite beam bridges.

The control module 31 will control the pump body 27 to supply oil to the two multi-stage telescopic cylinders 11, and the multi-stage telescopic cylinders 11 will unfold, so that the four groups of lifting components 8 will lift the scattered bracket to a certain height. Subsequently, due to the rigid connection of the scattered bracket, the two auxiliary components 1 can be pushed to move at the same time, which will cause the auxiliary components 1 on both sides to move, so that the structure composed of the two groups of auxiliary components 1 and the scattered bracket moves to both sides of the fixed scattered bracket, and then the two sliding frames 7 are aligned with the two legs on one side of the scattered bracket, and then the control module 31 is operated again. The control module 31 will control the pump body 27 to pump the hydraulic oil inside the multi-stage telescopic cylinder 11 back to the oil tank 26, so that the position of the upper scattered bracket falls, so that the upper and lower parts of the two scattered brackets are docked together.
