The invention relates to a multi-machine cooperative hoisting system and process for a box girder of a cut highway bridge of an upper-span in-construction railway. According to the method, a precast girder field is arranged beside a bridge site by means of a cut top station crane A (40) positioned on an existing road (8) at the bridge head and a roadbed station crane C (2) and a roadbed station crane B (3) which are positioned in a bridge site hoisting area, and a gun carriage (38) used for conveying the box girder (1) to the hoisting area is arranged between the girder field and the bridge site; a hoisting point A (9) and a hoisting point B (10) are pre-arranged at the two ends of the box girder (1); and a middle span (5) is pre-arranged in the middle of a bridge pier (4), side spans (6)are arranged at the two ends of the middle span (5), and a cut top station is positioned at the slope top of a roadbed side slope. The multi-machine cooperative hoisting system is reasonable in design, compact in structure and convenient to use.
本发明涉及上跨在建铁路路堑公路桥箱梁多机协同吊装系统及工艺,该方法借助于位于桥头既有道路(8)的堑顶工位起重机A(40)及在桥址吊装区域处的路基工位起重机C(2)与路基工位起重机B(3),桥址旁设置预制梁场,在梁场与桥址之间设置有用于运送箱梁(1)至吊装区域的炮车(38);在箱梁(1)两端预设有A吊点(9)及B吊点(10);在桥墩(4)中间预设有中间跨(5),中间跨(5)两端有边侧跨(6),堑顶工位在路基边坡坡顶处;本发明设计合理、结构紧凑且使用方便。
