Double-splicing coupling installation method for arch ribs of fully-assembled steel tube arch bridge
The invention provides a full-fabricated steel tube arch bridge arch rib double-splicing coupling installation method, and belongs to the technical field of arch bridge steel structure construction. (2) truss pieces are installed; 3, arch rib sections are installed; 4, mounting an arch rib flange; 5, wind brace installation; step 6, digitally simulating and assembling; and step 7, scanning and inspection. According to the invention, a horizontal and vertical double-splicing coupling mounting method of the arch rib is adopted, and a three-dimensional laser scanning digital simulation splicing technology is matched, so that the splicing efficiency and precision are improved, and the arch rib is smoothly mounted at high altitude; according to the component machined through the technology, when high-altitude hoisting is carried out, restoring installation is carried out according to the vertical splicing state, two wind braces are installed every day, and compared with welding for 4-5 days per piece, the situation that key lines are occupied by wind brace installation is effectively avoided, the time of an arch rib large cantilever is greatly shortened, and the structural risk is effectively reduced.
本发明提供全装配式钢管拱桥拱肋双拼耦合安装方法，属于拱桥钢结构施工技术领域，包括以下步骤：步骤1，弦管接长；步骤2，桁片安装；步骤3，拱肋节段安装；步骤4，拱肋法兰安装；步骤5，风撑安装；步骤6，数字化模拟拼装；步骤7，扫描报检。本发明采取拱肋卧式和立式双拼耦合安装方法，并配合三维激光扫描数字化模拟拼装技术，提升拼装的效率和精度，使得拱肋在高空安装顺利进行；应用该技术加工的构件，高空吊装时，按照立拼状态进行还原安装即可，风撑安装每天完成2个，相比焊接4‑5天/每个，有效地避免风撑安装占据关键线路，大幅度降低拱肋大悬臂的时间，有效地降低结构风险。
