Energy dissipation pier structure and construction method and application thereof
The invention discloses an energy dissipation and seismic mitigation pier structure and a construction method and application thereof.The energy dissipation and seismic mitigation pier structure comprises hollow piers, cross beams, disc spring self-resetting energy dissipaters, rubber seismic isolation cushion layers and foam concrete columns, the foam concrete columns are arranged in the middlesof the hollow piers, and the cross beams are arranged between the hollow piers and the foam concrete columns at intervals; wherein the cross beam is connected with the foam concrete column through thedisc spring self-resetting energy dissipater, the disc spring self-resetting energy dissipater is connected with the cross beam through bolts, the disc spring self-resetting energy dissipater is connected with the foam concrete column through bolts, and a rubber shock insulation cushion layer is arranged between the disc spring self-resetting energy dissipater and the foam concrete column. Energydissipation, seismic mitigation and self-resetting capacity of the bridge pier structure in all directions under the action of seismic loads is achieved, the seismic capacity of the bridge structureis improved, and good economic benefits and engineering application prospects are achieved; the foam concrete columns and the cross beams are poured while the hollow pier is poured, the foam concretecolumns are reinforced, the structure bearing capacity is improved, the structure is simple, and construction is convenient.
本发明公开了一种耗能减震桥墩结构及其施工方法和应用，结构包括空心桥墩、横梁、碟簧自复位耗能器、橡胶隔震垫层、泡沫混凝土柱，所述泡沫混凝土柱设置在空心桥墩中间，所述空心桥墩与泡沫混凝土柱之间间隔地设置横梁，所述横梁与泡沫混凝土柱之间用碟簧自复位耗能器连接，所述碟簧自复位耗能器与横梁之间、与泡沫混凝土柱之间均为螺栓连接，且中间均垫有一层橡胶隔震垫层。本发明实现了桥墩结构在地震荷载作用下各方向的耗能减震与自复位能力，提高了桥梁结构的抗震能力，具有良好的经济效益与工程应用前景；本发明浇筑空心桥墩的同时浇筑泡沫混凝土柱和横梁，泡沫混凝土柱加筋，提升结构承载能力，结构简单，施工方便。
