Prefabricated assembled hollow pier based on UHPC joints and construction method
The invention discloses a prefabricated assembled hollow pier based on UHPC joints and a construction method of the pier, the prefabricated assembled hollow pier comprises a pier column and a base, the pier column is a hollow pier column, the pier column is sequentially composed of a pier bottom section, a middle section and a top cap section from bottom to top, the pier bottom section is located at the top of the base, steel bar connectors are embedded between the pier bottom section and the base, between the pier bottom section and the middle section and between the middle section and the top cap section, reinforcing stirrups are arranged outside the steel bar connectors, and connection is achieved through post-pouring of UHPC joints. According to the invention, the steel bar connectors between the sections are easy to position and connect, the height of the joints is remarkably reduced, and the using amount of joint concrete is small; the segment construction tolerance is large, and the precision requirement is low; joints are free of vibration, self-compaction is achieved, pouring is convenient, and construction is simple; and the assembled pier is excellent in overall performance, high in joint durability, rapid to assemble, short in field operation time and high in efficiency.
一种基于UHPC接缝的预制拼装空心桥墩及其施工方法，具有墩柱和基座，所述墩柱为空心墩柱，所述墩柱从下至上依次由墩底节段、中间节段、顶帽节段组成，墩底节段位于基座顶部，墩底节段与基座之间、墩底节段与中间节段之间、中间节段与顶帽节段之间均预埋钢筋接头，钢筋接头外设有加强箍筋，后浇UHPC接缝实现连接，本发明使节段间钢筋接头定位、连接简单，接缝高度显著减小，接缝混凝土用量小；节段施工容差大，精度要求低；接缝免振捣、自密实便于浇筑，施工简单；拼装墩整体性能优良，接缝耐久性强，拼装快捷，现场作业时间短、效率高。
