Method for erecting steel plate combined continuous beam in mountainous area
The invention discloses a mountainous area steel plate combined continuous beam erecting method which comprises the following steps: firstly selecting a beam lifting point, assembling an operation bridge floor, then carrying out bridge erecting unit splicing, beam feeding and main beam whole-hole erecting on a bridge through the operation bridge floor, hoisting a steel beam by two crown blocks to synchronously move forwards until the front end of the steel beam moves to the front of a front supporting leg, descending the steel beam by a No.1 crown block, and finally erecting the steel plate combined continuous beam on the operation bridge floor. The second crown block descends, the steel beam is adjusted to be horizontal, the two crown blocks move synchronously, the position of the steel beam is adjusted, and the steel beam falls to the upper portion of the supporting seat, so that the front supporting leg cross beam of the bridge girder erection machine is heightened, the front supporting leg cross beam of the bridge girder erection machine is heightened, and the front supporting leg cross beam of the bridge girder erection machine is lowered to the lower portion of the front supporting leg cross beam of the bridge girder erection machine is lowered to the upper portion of the supporting seat. When the steel beams are erected, one ends of the steel beams descend to extend out of the front supporting legs, then butt joint is adjusted, fixed connection is carried out, full-hole erection of the continuous beams is achieved through the bridge girder erection machine, the scheme further explains an erection method of the steel beams and the boundary beams on the two sides of the bridge, and the front supporting legs fixed to the bridge piers do not affect erection of the edge steel beams.
本发明公开了一种山区钢板组合连续梁架设方法，先选定提梁点，组装作业桥面，然后通过作业桥面在桥上进行架桥机组拼、喂梁、主梁整孔架设，其中两台天车吊着钢梁同步前移，直至钢梁前端移动到前支腿前停止，1号天车下降钢梁,接着两台天车同步前移，然后重复下降、前移的步骤，直至使钢梁前端能从前支腿横梁下方穿过，2号天车下降，将钢梁调整水平，然后两台天车同步移动，调整钢梁位置，将钢梁落梁在支座上方，本发明对架桥机的前支腿横梁进行加高设计，钢梁架设时一端下降探出前支腿，然后再调整对接，并进行固定连接，通过架桥机实现了连续梁的整孔架设，本方案中还说明了桥梁两侧钢梁边梁的架设方法，使固定在桥墩上的前支腿不影响边缘钢梁的架设。
