Stepped open caisson foundation and construction method thereof
The invention relates to a stepped open caisson foundation and a construction method thereof. The stepped open caisson foundation comprises an upper open caisson, a lower open caisson and a buffer part, wherein the lower open caisson is used for being buried below a riverbed and located below the upper open caisson, and the lower open caisson extends out for a preset length in the horizontal direction relative to the upper open caisson; and the buffer part is used for weakening the lower submersible flow and is positioned at the joint of the upper open caisson and the lower open caisson. According to the stepped open caisson foundation and the construction method thereof, the protection effect can also be achieved without independently building protection measures around a pier, later tedious and complex work and high repair and maintenance cost are avoided, and higher economic benefits are achieved.
本发明涉及一种台阶式沉井基础及其施工方法，其包括：上部沉井；用于埋设于河床以下的下部沉井，位于所述上部沉井的下方，且所述下部沉井相对于所述上部沉井在水平方向伸出预设长度；以及用于削弱下潜水流的缓冲部，其位于所述上部沉井与所述下部沉井的衔接处。本发明涉及的一种台阶式沉井基础及其施工方法，不需要在桥墩周围单独建造防护措施也可以达到防护效果，避免了后期繁琐复杂的工作和高额的修缮维护费用，有着较高的经济效益。
