Construction method of Y-shaped pier continuous rigid frame bridge
The invention discloses a construction method of a Y-shaped pier continuous rigid frame bridge, and relates to the field of bridge construction. During construction, pile foundations and bearing platforms are constructed at designed positions, vertical pier columns are constructed, temporary supports are installed at the tops of the vertical pier columns, temporary supporting frames are arranged between the vertical pier columns, the temporary supports, the temporary supporting frames and the vertical pier columns are used as formwork supporting points, beam bodies are poured, and the formwork supporting points are formed. And V-shaped supporting arms are constructed at the designed positions on the vertical pier columns, the supporting arm formworks, the temporary supports and the temporary supporting frames are dismantled after construction is completed, and construction is completed. According to the construction scheme, the problems that in an existing scheme, the construction time is long, the occupied construction site is large, the influence on narrow areas of cities and operation sites is very obvious, the stress of a temporary support is large, the structure of the temporary support is complex, and the safety risk of construction is high are solved.
本发明公开了一种Y型墩连续刚构桥的施工方法，涉及桥梁建设施工领域。其施工时在设计好的位置施工桩基及承台，施工竖直墩柱，在所述竖直墩柱顶部安装临时支撑，在所述竖直墩柱之间设置临时支撑架，以所述临时支撑、临时支撑架及竖直墩柱为模架支点，浇筑梁体，在所述竖直墩柱上设计的位置施工V型支撑臂，完成后拆除支撑臂模板、临时支撑及临时支撑架，完成施工。该施工方案解决了现有方案中不仅施工时间长且占用的施工场地大，对城市及作业场地狭小的区域影响十分明显，而且临时支架受力大，临时支架结构复杂，施工的安全风险高的问题。
