架桥机更换既有铁路桥梁施工技术

Construction Technology of Bridge Machine Replacing Existing Railway Bridges

以既有线更换桥梁施工为例,详细介绍架桥机更换施工过程,重点从架桥机在既有线上的布置、梁片运输、旧梁拆除、新梁架设及线路恢复等方面进行阐述。通过多次论证及方案优化,对施工全过程进行有效把控,最终安全、顺利地完成了北京市域铁路S5线的旧梁更换任务,成功地解决了架桥机更换旧梁的施工难题。

Taking the replacement of existing railway line bridges as an example,the replacement construction process of the bridge machine is introduced in detail.The layout of the bridge machine,beam transport,old beam removal,new beam erection and line recovery are described.Through a number of demonstrations and program optimization,the entire construction process is effectively controlled,and the old beam replacement task of the Beijing area railway S5 line is finally completed safely and smoothly.It successfully solves the construction problem of replacing the old beam by the bridge machine.
