Fabricated pier connecting structure capable of adjusting seismic capacity and construction method of fabricated pier connecting structure
The invention discloses an assembly type pier connecting structure capable of adjusting the shock resistance and a construction method thereof. The structure comprises an embedded mechanism arranged in a bearing platform and a socket mechanism arranged on a pier, and a plurality of vertical steel bars are arranged in the pier in the circumferential direction; the socket mechanism comprises a concrete connecting block arranged at the bottom of the pier and a rubber damping layer wrapping the outer side wall of the concrete connecting block. The pre-burying mechanism comprises a plurality of corrugated pipe sleeves buried in the bearing platform and reserved notches formed in the bearing platform. The number of the corrugated pipe sleeves is equal to that of the vertical steel bars, and the corrugated pipe sleeves and the vertical steel bars are in one-to-one correspondence. The method comprises the following steps: 1, manufacturing the fabricated bridge pier; 2, processing a bridge bearing platform; and 3, connecting the pier and the bearing platform. By adding the rubber damping layer, the structural ductility of the bridge pier is improved, so that the design acceleration response spectrum of the bridge pier is reduced, the bridge pier can adapt to higher-intensity earthquakes, and the risks of bridge pier damage and bridge instability under the high-intensity earthquakes are reduced.
本发明公开了一种可调整抗震能力的装配式桥墩连接结构及其施工方法，该结构包括设置在承台内的预埋机构和设置在桥墩上的承插机构，桥墩内周向设置有多根竖向钢筋；承插机构包括设置在桥墩底部的混凝土连接块和包裹在混凝土连接块外侧壁上的橡胶减震层；预埋机构包括多个埋设在承台内的波纹管套筒和开设在承台上的预留槽口，波纹管套筒的数量与竖向钢筋的数量相等且一一对应。该方法包括步骤：一、制作装配式桥墩；二、加工桥梁承台；三、连接桥墩与承台。本发明通过增加橡胶减震层，增加了桥墩的结构延性，从而降低了桥墩的设计加速度反应谱，能够适应更高烈度的地震，并且降低了高烈度地震下桥墩破坏和桥梁失稳的风险。
