Overwater butt joint method for floating bridge single bodies
The invention discloses an overwater docking method for floating bridge single bodies. The overwater docking method comprises the following steps that jacking supports are erected on the water; the two sections of floating bridge single bodies are hauled into the working range of the jacking support; preliminarily adjusting butt joints of the main beam sections of the two floating bridge single bodies on the jacking bracket; the two sections of floating bridge single bodies are dragged to the middle of the jacking support through a walking type jack on the jacking support; the weight of the butt joint of the two main beam sections is borne by a supporting cushion block on the jacking support; the butt joints of the two main beam sections are further pulled and closed through a longitudinal pulling and closing oil cylinder; the transverse position of the butt joint of the two main beam sections is adjusted through a transverse fine adjustment oil cylinder; the welding work between the end faces of the butt joints of the two main beam sections is completed, and a section of floating bridge unit is formed; the jacking support is separated from the floating bridge unit through the walking type jack; and the floating bridge unit is dragged away from the working range of the jacking support. It is effectively guaranteed that stress and deformation of the floating bridge single bodies meet the design requirements during butt joint.
本发明公开了一种浮桥单体的水上对接方法，包括以下步骤：在水上搭设顶升支架；将两段浮桥单体拖运到顶升支架的工作范围内；在顶升支架上对两段浮桥单体的主梁节段的对接头初步调整；由顶升支架上的步履式千斤顶将两段浮桥单体向顶升支架的中部拖动；将两根主梁节段的对接头的重量由顶升支架上的支撑垫块承担；通过纵向拉合油缸将在两根主梁节段的对接头进一步拉合；通过横向精调油缸调节两根主梁节段的对接头横向位置；完成两根主梁节段的对接头的端面之间的焊接工作，形成一段浮桥单元；通过步履式千斤顶使顶升支架脱空浮桥单元；将浮桥单元拖离顶升支架的工作范围。本发明有效保证了浮桥单体在对接时的受力和变形满足设计要求。
