The invention relates to a whole-section splicing process for a steel truss girder of a main channel bridge. The whole-section splicing process is characterized by comprising the following specific splicing processes: S1, splicing truss pieces; s2, assembling an upper-layer highway steel bridge deck slab; s3, splicing a lower-layer railway steel box bridge deck slab; s4, the whole sections are spliced; a continuous splicing mode is adopted, the truss pieces, the upper-layer bridge deck and the lower-layer bridge deck are independently installed in a multi-wheel mode, and a section is reserved on the basis of splicing of the previous wheel to serve as a mother section of the next wheel to participate in installation, so that smooth connection between every two adjacent structures can be guaranteed, and the installation precision is guaranteed; the lower-layer bridge floor, the truss pieces and the upper-layer bridge floor are sequentially assembled, and then the last one is disassembled, loaded and assembled on site, so that the overall assembling efficiency of the large steel truss girder section is improved, and the assembling precision is ensured.
Description
technical field [0001] The invention relates to the field of steel truss girder, in particular to a whole segment assembling process of a steel truss girder of a main channel bridge. Background technique [0002] With the rapid development of society and economy, the pressure of land transportation is becoming more and more prominent. In order to solve this pressure, it is imperative to build a large number of railways, highways and other projects. The use of bridges tends to be inevitable, and people are also designing the structures of bridges with different distances. [0003] At present, some steel trusses are in the form of upper and lower layers, the sides of the upper and lower decks are connected by trusses, and the upper deck and the lower deck are laid with bridge deck units on T-shaped beams. Since each part is manufactured separately in the manufacturing process, when assembling at the site, due to the bolt connection, high precision is required, so it is essent...
