Self-resetting assembled bridge pier with replaceable energy-dissipation shear parts and construction method of self-resetting assembled bridge pier
The self-resetting assembled pier comprises a bearing platform, a foundation groove allowing the bottom of a prefabricated RC pier to be inserted is formed in the top of the bearing platform in a concave mode, the bottom of the prefabricated RC pier is coaxially sleeved with a pier bottom steel sleeve, and a steel base used for abutting against the pier bottom steel sleeve is fixedly arranged at the top in the foundation groove; prestressed tendons vertically penetrate through the center of the steel base and the center of the prefabricated RC pier, the two ends of the steel base and the center of the prefabricated RC pier are anchored and fixed, an annular anchoring bottom steel plate is embedded in the surface of the bearing platform outside the foundation groove, a plurality of shear parts are fixedly arranged on the pier bottom steel sleeve at intervals along the periphery, and the lower ends of the shear parts are welded to the anchoring bottom steel plate; a rubber cushion block is arranged on the anchoring bottom steel plate along the inner circumferential wall of the anchoring bottom steel plate in a cushioned mode, and an annular asphalt hemp knife is arranged between the rubber cushion block and the pier bottom steel sleeve located in the foundation groove. Therefore, the integrity of the RC pier structure is ensured.
本发明涉及一种可更换耗能剪力件的自复位拼装桥墩及其施工方法，包括有承台，所述承台顶部凹设有供预制RC桥墩底部插入的基础槽，预制RC桥墩底部外同轴套设有墩底钢套筒，基础槽内顶部固设有用以抵接墩底钢套筒的钢底座，钢底座与预制RC桥墩中心均经预应力筋竖向贯穿且两端均锚固固定，基础槽外的承台表面嵌设有环形的锚固底钢板，墩底钢套筒沿其外周间隔固设有若干剪力件，该剪力件下端均焊接在锚固底钢板上；所述锚固底钢板沿其内环周壁垫设有橡胶垫块，所述橡胶垫块与位于基础槽内的墩底钢套筒之间设置有环形的沥青麻刀，该桥墩结构具有良好的地震可恢复性，整体耗能能力强，能够有效地将地震损伤引导至剪力件上，从而保证RC桥墩结构完整。
