The invention relates to a construction method for single-span integral floating transportation and installation of a trestle superstructure, which comprises the following steps of: erecting a bracket on a barge, assembling the one-span trestle superstructure into a whole on the barge bracket by using a crane on a wharf, transporting the whole-span trestle superstructure to one side of a trestle, and jacking the whole-span trestle superstructure on the ship to be higher than a pile top bearing beam by using a jack; and then the barge is moved to the middle of the bridge span, the jacks return oil to enable the bailey beams to fall onto the pile top bearing beams, and installation of the upper structure of the one-span trestle is completed. The assembling operation of the trestle superstructure is transferred to the land from the water, the water construction time is short, trestle steel pipe pile inserting and driving and superstructure assembling can be synchronously constructed, the trestle superstructure can be integrally installed in a single-span mode, the construction speed is high, and the efficiency is high.

    本发明涉及一种栈桥上部结构单跨整体浮运安装施工方法,在驳船上搭设支架,在码头上用吊车在驳船支架上将一跨栈桥上部结构拼装成整体,船运至栈桥一侧,用千斤顶将船上的整跨栈桥上部结构顶升至高于桩顶承重梁,然后将驳船移动到桥跨中间,千斤顶回油将贝雷梁落到桩顶承重梁上,完成一跨栈桥上部结构安装。本发明将栈桥上部结构的组装作业由水上转移至陆地上,水上施工时间短,栈桥钢管桩插打与上部结构拼装可同步施工,栈桥上部结构可单跨整体安装,施工速度快,效率高。
