近年来,在新建铁路工程中,对于钢梁的架设,大都采用悬臂拼装、拖拉、膺架法等提前预架,以争取铺轨工程的进度。但在枝柳线施溶溪大桥架设钢板梁时,在隧道口架桥机不能起臂的情况下,我们用65-53型悬臂架桥机整孔架设跨度40米上承焊接板梁,这一工程,只用了3天就完成了架梁和桥上铺轨任务。现将该桥的架设情况介绍如下。 In recent years, in the construction of new railway projects, most of the steel girders are erected in advance by cantilever assembling, dragging, scaffolding, etc. in order to win the progress of the laying project. However, in Liushi line Liuxi bridge erection of steel girder, the tunnel erecting machine can not be used in the case, we use 65-53 cantilever erecting machine erection of 40 meters across the span of welded plate girder, which A project, completed only three days to rack beams and bridge laying track task. The bridge is now erected as follows.
