襄渝线28孔23.8m直线П形无碴无枕梁的架设实践证明,这种梁比分片有碴有枕梁架设速度提高一倍,平均用1小时44分钟架设一孔。随着架设技术的熟练,架桥设备和安装扣件工具的不断改进,平均1.5小时架设一孔是完全可能的。由于П形无碴无枕梁架设快,在新建铁路中就可大大缩短铺架时间,给现场施工单位争取了更多的施工时问,有的工点就不需要采取
Xiang-Yu line 28 holes 23.8m straight line Π Ballastless pillow-free beam erection Practice has proved that this beam than the ballast has a pillow with erection speed doubled, with an average of 1 hour and 44 minutes to set up a hole. With skill in erection technology, continuous improvement of bridging equipment and installation of fastener tools, it is entirely possible that an average of 1.5 hours to erect a hole. Due to the rapid installation of the ballastless beam without beam, the laying time can be greatly shortened in the construction of the new railway, and more construction time is required for the construction unit on site, and some work points do not need to be taken
