Main channel bridge steel truss girder whole section splicing process
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.
本发明涉及一种主航道桥钢桁梁整节段拼装工艺，特征在于：具体拼装工艺如下：S1：桁片拼装；S2：上层公路钢桥面板拼装；S3：下层铁路钢箱桥面板拼装；S4：整节段的拼装；采用连续拼装的方式，桁片、上层桥面、下层桥面均采用多轮独立安装且在上一轮拼装的基础上留下一段作为下一轮的母段参与安装，从而可以保证相邻的各结构之间的顺利连接从而保证安装的精度；采用由下层桥面、桁片、上层桥面的拼装顺序依次拼装最后一个再解体装运现场拼装，提高了钢桁梁大节段的整体拼装效率，保证了拼装精度。
