Superimposed assembly type double-wall corrugated steel pipe concrete pier and construction method thereof
The invention provides a superposed assembly type double-wall corrugated steel pipe concrete pier and a construction method thereof, and belongs to the field of bridge structural members. The pier comprises a top cover beam, a middle double-wall corrugated steel pipe concrete column and a lower bearing platform. The middle double-wall corrugated steel pipe concrete column comprises an inner steel pipe, interlayer concrete and an outer corrugated steel pipe, the cover beam and the bearing platform comprise reserved cup openings and structures for achieving joint connection, and self-compacting fine aggregate concrete is adopted as post-pouring concrete. According to the structure and the anti-corrosion advantage of the corrugated steel pipe, the corrugated steel pipe is applied to a pier body, a column lengthening area, a column and cover beam connecting area and a column and bearing platform connecting area, and an interlayer double-wall structure is adopted in the pier; the column body is lengthened by overlapping and splicing the steel pipes and then pouring the concrete, and the embedding depth of the pier body in the bearing platform and the bent cap is reduced. The invention has the characteristics of high assembly efficiency, light self weight, excellent corrosion resistance, good anti-seismic property, high construction speed and the like.
本发明提出了一种叠合装配式双壁波纹钢管混凝土桥墩及其施工方法，属于桥梁结构构件领域。该桥墩包括顶部盖梁、中部双壁波纹钢管混凝土柱和下部承台；中部双壁波纹钢管混凝土柱包括内部钢管、夹层混凝土、外部的波纹钢管，盖梁和承台包括预留杯口以及实现节点连接的构造，后浇混凝土采用自密实细骨料混凝土。本发明利用波纹钢管的结构与防腐优势，将其应用于桥墩墩身、柱接长区、柱与盖梁连接区以及柱与承台连接区，并在桥墩内部采用夹层双壁结构，配置截面开展的钢管，通过钢管的叠合拼接再后浇混凝土实现了柱身加长、降低了墩身在承台与盖梁内的埋置深度。本发明具有装配效率高、自重轻、耐腐蚀性能优异、抗震性能好、施工速度快等特点。
