Composite anchorage foundation suitable for large-span suspension bridge and construction method of composite anchorage foundation
The invention discloses a composite anchorage foundation suitable for a large-span suspension bridge and a construction method of the composite anchorage foundation. The composite anchorage foundation comprises single open caissons and steel pipe piles arranged at the lower ends of the single open caissons. The steel pipe piles and the single open caissons are poured into a whole; the single open caissons comprise open caisson walls, open caisson partition walls and open caisson cover plates arranged at the upper ends of the open caisson partition walls; all the open caisson walls form a rectangle, any two parallel open caisson walls are connected through the multiple open caisson partition walls, and the open caisson partition walls are parallel to the open caisson walls and are lower than the open caisson walls; open caisson holes are formed between the open caisson partition walls and the open caisson walls and between the open caisson walls; bottom sealing concrete is arranged at the bottoms of the open caisson holes, well hole filling cores are arranged between the open caisson cover plates and the bottom sealing concrete; and through reserved pile holes are formed in the open caisson partition walls and the open caisson walls, the steel pipe piles are arranged in the reserved pile holes, and the tops of the steel pipe piles are embedded into the bottoms of the reserved pile holes. According to the composite anchorage foundation suitable for the large-span suspension bridge, the buried depth of the single open caissons can be reduced, and the anchorage construction difficulty can be reduced.
本发明公开了一种适用于大跨径悬索桥的复合锚碇基础及其施工方法，该基础包括单体沉井和设于单体沉井下端的钢管桩；钢管桩和单体沉井浇筑成为一个整体；所述单体沉井包括沉井井壁、沉井隔墙和设于沉井隔墙上端的沉井盖板；所有沉井井壁形成一个矩形，任意两个平行的沉井井壁之间均通过若干沉井隔墙连接，沉井隔墙平行于沉井井壁且其高度低于沉井井壁；沉井隔墙与沉井井壁之间、沉井井壁与沉井井壁之间形成沉井井孔；沉井井孔底部设有封底混凝土，沉井盖板和封底混凝土之间设有井孔填芯；沉井隔墙和沉井井壁上均设有贯通的预留桩孔，钢管桩设于预留桩孔中且其顶部嵌入预留桩孔底部。本发明不仅能减小单体沉井的入土深度，还能降低锚碇施工难度。
