二密河大桥上部结构的施工技术

Construction Techniques for the Superstructure of the Ermi River Bridge

针对二密河大桥位于曲线段上且与线路斜交的情况,介绍了箱梁预制和架设的过程,重点介绍了曲线运梁、架桥机前移及斜交梁架设、落梁等关键技术,对同类工程有借鉴意义。

With the Ermi River Bridge as a practical example, which is on a curved line and intersects a highway, the box girder-pre-casting and erecting processes are presented in the paper, with stress placed on the key techniques for the transportation of girders on the curved line, the moving forward of the bridge erector and the erection of the obliquely intersecting girders, as well as the lowering of girders. The project may serve as a useful reference for other similar projects.
