箱梁架设前高桥墩快速测量交接技术研究

Research on fast measurement jointing technique at high piers before erection of box girder

结合架桥机架设客运专线预制箱梁的实际过程,根据现场施工经验,得出箱梁架设前高桥墩快速测量交接技术,提高了施工效率,降低了安全风险,增加了箱梁架设工程的经济效益,可为以后类似工程施工提供指导。

Combining with the factual process for the erection of the precast box girder along passenger special lines with the bridge machine, the study concludes the fast measurement jointing technique at high piers before the erection of box girders according to the field construction experi- ence to improve the construction efficiency, lower the safety risks, and increase the economic benefits in the box girder erection projects, so as to provide the direction for similar projects.
