长襄安居铁路桥平转施工技术

Flat rotating construction technology of Chang-Xiang Anju railway

结合长襄安居铁路桥工程实例,从转盘构造、梁体称重、平面转体施工、合龙段施工四方面,阐述了转体施工的关键技术,提高了施工的安全性,减小了上行桥梁施工对下行交通的影响。

Combining with Chang-Xiang Anju railway bridge engineering example,starting from four aspects of turntable structure,beam weighing,flat rotating construction and closure segment construction,the paper describes critical rotating construction techniques. As a result,it not only improves the construction safety,but also reduces the influence of upper bridge construction upon low traffic.
