跨双线铁路门式墩横梁偏位现浇后顶推就位技术研究

Research on the Pushing Placement Technology of Deflection of Cross Beam of Portal Piers across Double-track Railway after Cast-in-situ

本文详细阐述了跨焦柳线特大桥门式墩横梁偏位现浇后顶推就位的新技术,减少了减少营业线施工项目及涉铁施工时间,取得了良好的安全、工期及经济效果,以期以类似涉铁工程的施工提供技术思路。

This article elaborates on the new technology of pushing in place the cross beams of the gate piers across the Jiaoliu line large bridge after being cast off-site,which reduces the business line construction projects and railway-related construction time,and achieves good safety,construction period and economic effects,with a view to providing technical ideas for similar construction projects.
