Self-resetting pier aseismic structure and construction method thereof
The invention provides a self-resetting bridge pier anti-seismic structure. The self-resetting bridge pier anti-seismic structure comprises a bridge pier upper section, prestressed tendons, a steel casing, an upper tooth-shaped swing joint, a foundation, an annular damper, a limiting duckbill, a limiting duckbill hole, an upper rigid embedded connector, a lower rigid embedded connector and a bridge pier lower section. The pier upper section is a square column; an upper tooth-shaped swing joint is arranged on the lower end face of the upper pier section; the pier lower section is a square column; a lower tooth-shaped swing joint is arranged on the upper end face of the lower pier section; the upper tooth-shaped swing seam and the lower tooth-shaped swing seam are meshed with each other; the steel casing is a square sleeve; the steel casing sleeves the outer side of the lower section of the bridge pier; the lower part of the pier upper section is positioned in the steel casing; the opening and closing of the upper tooth-shaped swing joint and the lower tooth-shaped swing joint can prevent the concrete of the pier upper section and the pier lower section from being damaged by tension, the original concrete of the plastic hinge areas of the pier upper section and the pier lower section can be obviously reduced by the tension damage, and the tooth-shaped bulges can provide certain shear resistance for the pier.
本发明提供一种自复位桥墩抗震构造抗震构造，包括：桥墩上节段、预应力筋、钢护筒、上齿状摇摆接缝、基础、环形阻尼器、限位鸭嘴、限位鸭嘴孔、上钢性嵌合式接头、下钢性嵌合式接头和桥墩下节段；桥墩上节段为方形柱；桥墩上节段下端面设置有上齿状摇摆接缝；桥墩下节段为方形柱；桥墩下节段上端面设置有下齿状摇摆接缝；上齿状摇摆接缝和下齿状摇摆接缝相互啮合；钢护筒为方形套筒；钢护筒套设在桥墩下节段外侧；桥墩上节段下部位于钢护筒内；上齿状摇摆接缝和下齿状摇摆接缝的张开闭合可以防止桥墩上节段和桥墩下节段的混凝土的受拉破坏也能显著减少原来桥墩上节段和桥墩下节段塑性铰区混凝土的受拉破坏而且齿状凸起还能够为桥墩提供一定的抗剪能力。
