Suspension bridge steel truss girder mounting method
The invention relates to the technical field of bridge installation and particularly relates to a suspension bridge steel truss girder mounting method. Rigid connection construction of a hoisting beamsection is carried out step by step along with hoisting, after hoisting is required to be completely completed in a traditional method, each two are rigidly connected and then integrally and rigidlyconnected, a large amount of rigid connection construction needs to be carried out at the same time, personnel and equipment resource input is large, construction cost is high, rigid connection operation occupies a main line construction period, and a whole bridge construction period is prolonged. By the adoption of the method, the input amount of rigid connection construction resources is reduced, the bridge construction period is shortened, and the method is simple in suspension bridge steel truss girder connection sequence, small in high-altitude rigid connection operation amount and low insafety risk.
本发明涉及桥梁安装技术领域，具体涉及一种悬索桥钢桁梁安装方法，通过吊装梁段的刚接施工随着吊装的进行逐步进行，传统方法要求吊装全部完成后，先两两刚接,再整体刚接，需要同时进行大量的刚接施工，人员设备资源投入量大，施工成本高，刚接作业占用主线工期，延长整个桥梁的施工工期。采用本发明的方法降低了刚接施工资源投入量，所缩短了桥梁施工工期，本发明的方法具有悬索桥钢桁梁连接顺序简单，高空刚接作业量少，安全风险底的特点。
