Box girder erection method and box girder prefabricating mold for high-speed railway construction
The invention provides a box girder erection method and a box girder prefabricating mold for high-speed railway construction.The box girder erection method comprises the following steps that two gantry crane frames are driven to move to preset positions along longitudinal linear rails, and jacking assemblies on pier columns lift the gantry crane frames; the rail wheels of the two gantry crane frames are separated from the longitudinal linear rail; the longitudinal positioning beams on the two sides of the pier column are disassembled, transverse positioning beams are installed at the corresponding positions, and the transverse positioning beams are provided with transverse linear rails arranged in the second preset direction; the rail wheels of the gantry crane frame are changed from longitudinal arrangement to transverse arrangement, the jacking assembly places the gantry crane frame on the transverse positioning beam, and the rail wheels of the gantry crane frame are in sliding connection with the transverse linear rails; and the two gantry crane frames are driven to move back to back along the transverse linear rails, so that the box girder deflects by a preset angle. Compared with a bridge girder erection machine erection mode, the bridge girder erection machine is lower in cost, is not limited by the width of a girder surface to move, and is not easy to overturn.
本发明提供了一种箱梁架设方法及高速铁路施工用箱梁预制模具，箱梁架设方法包括以下步骤：驱动两个龙门行车架沿纵向直线轨道移动至预设位置，墩柱上的顶升组件将龙门行车架抬升，以使两个龙门行车架的轨道轮脱离纵向直线轨道；拆卸墩柱两侧的纵向定位梁，并在对应位置安装横向定位梁，横向定位梁具有沿第二预设方向设置的横向直线轨道；将龙门行车架的轨道轮从纵向设置变为横向设置，顶升组件将龙门行车架放置至横向定位梁上，并使得龙门行车架的轨道轮与横向直线轨道滑动连接；驱动两个龙门行车架沿横向直线轨道相背移动，以使箱梁偏转预设角度。本发明相对于架桥机架设的方式，成本更低，且不受梁面宽度对移动的限制，不易发生倾覆。
