Post-earthquake repairable steel pipe reinforced UHPC prefabricated pipe spliced pier structure and construction method thereof
The invention relates to a post-earthquake repairable steel pipe reinforced UHPC prefabricated pipe assembled bridge pier structure and a construction method thereof. The post-earthquake repairable steel pipe reinforced UHPC prefabricated pipe concrete assembled bridge pier comprises steel pipe reinforced UHPC prefabricated pipes, an energy consumption assembly, a bearing platform, a cover beam and prestressed steel beams. Wherein the steel pipe reinforced UHPC prefabricated pipe is formed by splicing sections, and the prefabricated pipe sections and the cover beam are anchored on the bearing platform by tensioning prestressed steel beams, so that the bearing platform, the steel pipe reinforced UHPC prefabricated pipe and the cover beam are connected into a whole. The energy consumption assembly is composed of steel pipe reinforced UHPC prefabricated pipe section end steel plates, energy consumption keys, grooved steel plates and covering parts, the energy consumption keys are placed in clamping grooves formed by the grooved steel plates of the adjacent sections, and energy generated by an earthquake is consumed through the joint action of stretching the energy consumption keys between the adjacent sections and mutual extrusion between the end steel plates. The formed steel pipe reinforced UHPC prefabricated pipe assembled pier system has the advantages of being high in bearing capacity, good in anti-seismic performance, capable of being rapidly repaired after an earthquake, high in construction efficiency and the like.
本发明涉及一种震后可修复钢管增强UHPC预制管拼装桥墩结构及其施工方法，其中震后可修复钢管增强UHPC预制管混凝土拼装桥墩包括钢管增强UHPC预制管、耗能组件、承台、盖梁以及预应力钢束。其中，钢管增强UHPC预制管由节段拼装而成，预制管节段与盖梁通过张拉预应力钢束锚固在承台上，从而使承台、钢管增强UHPC预制管、盖梁连接形成整体。耗能组件由钢管增强UHPC预制管节段端钢板、耗能键、带槽钢板以及覆盖件组成，耗能键放置在相邻节段带槽钢板形成的卡槽中，通过拉伸相邻节段之间的耗能键与端钢板之间相互挤压的共同作用来消耗地震所产生的能量。所形成的钢管增强UHPC预制管拼装桥墩体系具有承载能力高、抗震性能好、震后可快速修复、施工效率高等优点。
