营业线高速铁路支座更换施工工艺及控制要点

On construction craft for bearing replacement on express railways along operating lines and their controlling points

结合某高速铁路支座更换工程实例,介绍了详细的施工工艺流程,并对营业线更换支座的技术措施及质量控制要点进行了阐述,经严格实施,取得了较为理想的施工效果,对今后同类工程施工具有一定的借鉴意义。

Combining with the bearing replacement projects on some express railway,the paper introduces the construction craft procedure,illustrates the technical measures for the bearing replacement on the operation line and the quality controlling points,and achieves the ideal construction effect,so as to provide some reference for similar projects in future.
