Double-line-to-single-line box girder erection method based on girder moving bracket platform
The invention discloses a double-line-to-single-line box girder erecting method based on a girder moving bracket platform. The method comprises the steps that the bracket platform is arranged on the side face of a target pier body; after the double-line box girder is erected, a first single-line box girder is erected in the middle of a target pier body, and temporary girder falling is conducted; transversely moving the first single-line box girder outwards by a preset distance to a bracket platform; erecting a second single-line box girder at the middle position of the target pier body and temporarily dropping the girder; transversely moving the second single-line box girder to a first target erection position towards the outer side in the opposite direction of the first single-line box girder; and transversely moving the first single-line box girder towards the inner side to a second target erection position. By using the translation bracket to erect the box girder, the problem that the transverse operation range of the bridge girder erection machine is small when double lines are changed into single lines can be effectively relieved.
本发明公开了一种基于移梁托架平台的双线变单线箱梁架设方法，包括：在目标墩身侧面布设托架平台；在双线箱梁架设完成后，在目标墩身中位架设第一单线箱梁并临时落梁；将第一单线箱梁向外侧横移预设距离至托架平台上；在目标墩身中位架设第二单线箱梁并临时落梁；将第二单线箱梁向与第一单线箱梁相反方向的外侧横移至第一目标架设位置；将第一单线箱梁向内侧横移至第二目标架设位置。本发明通过使用平移托架架设箱梁的方式，能够有效缓解双线变单线时架桥机横向作业范围小的问题。
