Sectional type swinging bridge pier
The invention relates to a sectional type swinging bridge pier, and belongs to the technical field of civil engineering earthquake resistance. Comprising a bent cap, an upper section, an upper energy dissipation area, a lower section, a lower energy dissipation area, prestressed steel bars, energy dissipation steel bars, PVC reserved hole channels, an upper protective cover and a lower protective cover. The components are sequentially connected from top to bottom, and a swing interface is formed between the upper energy consumption area and the lower energy consumption area. The centers of the components are provided with PVC reserved hole channels which are vertically through, and the components are connected in series and anchored together through prestressed steel bars in the PVC reserved hole channels. The upper energy consumption area and the lower energy consumption area are both larger than the upper section and the lower section, and PVC reserved hole channels penetrating through the upper energy consumption area and the lower energy consumption area are formed in the portions, larger than the upper section and the lower section, of the upper energy consumption area and the lower energy consumption area in a surrounding mode. Energy dissipation steel bars penetrate through the PVC reserved hole channels; the upper surface of the upper energy consumption area and the lower surface of the lower energy consumption area are each provided with an upper protective cover and a lower protective cover.
本发明涉及一种分段式摇摆桥墩，属于土木工程抗震技术领域。包括盖梁、上节段、上耗能区、下节段、下耗能区、预应力钢筋、耗能钢筋、PVC预留孔道、上保护盖、下保护盖；上述构件从上而下依次连接设置，上耗能区与下耗能区之间形成摇摆界面；上述构件中心设置有上、下贯穿的PVC预留孔道，其通过PVC预留孔道内的预应力钢筋串联锚固在一起；上耗能区以及下耗能区均大于所述上节段以及下节段，上耗能区以及下耗能区大于上节段以及下节段的部分环绕设置有贯穿上耗能区以及下耗能区的PVC预留孔道；PVC预留孔道内贯穿有耗能钢筋；上耗能区上表面、下耗能区下表面均设置有上保护盖以及下保护盖。
