Urban rail dual-purpose double-layer large-span steel truss and arch cooperative system bridge construction method
The invention relates to the technical field of municipal bridge engineering, in particular to an urban rail dual-purpose double-layer large-span steel truss and arch cooperative system bridge construction method which comprises the following steps: S100, construction preparation: designing a gantry crane mounting and dismounting project according to construction requirements; S101, carrying out a load test after the gantry crane is mounted, and judging whether the performance of each part of the gantry crane is perfect according to a test result; S102, hoisting standards and stacking requirements are designed according to the stress of the steel beam component; S103, coating a protective outer layer coating of the steel beam component through brushing; and S104, taking maintenance measures according to the properties of the steel beam component and the coating; the method has the characteristics that urban rails are shared, rail loads are located on the upper layer, a steel truss and arch collaborative system is adopted, and a flexible structure is adopted, so that the bridge has obvious advantages in the construction aspect, compared with construction of a traditional steel truss bridge, steel truss components can be transported more stably, the engineering timeliness is high, completion acceptance is strict, and the independent acceptance method is provided for the welding seam.
本发明涉及市政桥梁工程技术领域，具体涉及城轨两用双层大跨度钢桁架及拱协作体系桥梁施工方法，包括以下步骤：S100：施工准备，根据施工要求设计龙门吊安拆工程；S101：在龙门吊完成安装后进行负荷试验，根据试验结果判断龙门吊各部件性能是否完善；S102：根据钢梁构件应力设计吊装标准及堆放要求；S103：钢梁构件保护外层涂料涂刷；S104：根据钢梁构件及涂料的性质实施保养措施；本发明中提出的方法具有城轨公用且轨道荷载位于上层、钢桁架+拱协同体系、柔性结构等特点，使得该桥在施工方面具有明显的优势并且相比以往钢桁桥梁的施工能够更加稳定的对钢桁构件进行运输，工程时效性高，且竣工验收严谨，针对焊缝有单独的验收方法。
