Large-span deck type arch bridge girder hoisting construction method
The invention relates to a large-span deck type arch bridge girder hoisting construction method, which is characterized in that a girder hoisting system is arranged on an arch ring, and the girder hoisting system comprises two girder hoisting frames and two girder temporary shelving brackets; a girder transporting ship transports a girder section to the position below a bridge, the girder section is lifted to the two girder temporary shelving supports through the two winches of the girder lifting system, and then the girder section is lifted to the installation position from the girder temporary shelving supports through the cable crane. According to the cable crane, only the lifting beam needs to move longitudinally, repeated transverse movement is not needed, the risk of cable jumping and cable breaking is avoided, and construction safety can be guaranteed.
本发明涉及一种大跨度上承式拱桥主梁吊装施工方法，在所述拱圈上设置有主梁提吊系统，所述主梁提吊系统包括两个主梁提升架和两个主梁临时搁置支架；运梁船将主梁节段运至桥下，先通过主梁提升系统的两台卷扬机将主梁节段提吊至两主梁临时搁置支架上，再由缆索吊从主梁临时搁置支架上提吊主梁节段到安装位置。本发明缆索吊只需要提梁纵移，无需反复横移，避免了跳索和断索的风险，可保证施工安全。
