Segment-replaceable prefabricated assembled mixed pier and construction method thereof
The invention relates to a segment-replaceable prefabricated assembled mixed pier which comprises a pier body composed of a reinforced concrete pier column upper segment, a steel pipe concrete core column and a replaceable prefabricated hollow thin-wall steel pier lower segment. The reinforced concrete pier column upper segment and the steel pipe concrete core column are prefabricated into a whole and inserted into a cup groove reserved in the bearing platform, and the prefabricated hollow thin-wall steel pier lower segment is connected with the reinforced concrete pier column upper segment and the bearing platform through high-strength bolts. The prefabricated assembled pier is clear in structural stress and reliable in force transmission, has the characteristics of being capable of replacing the segments after being damaged under the action of strong earthquakes and rapidly recovering functions, and solves the problems that a traditional prefabricated assembled pier is poor in energy dissipation capacity, difficult to repair after being damaged by earthquakes and the like.
本发明涉及一种可更换节段的预制拼装混合墩，包括由钢筋混凝土墩柱上节段和钢管混凝土芯柱、可更换的预制空心薄壁钢桥墩下节段共同组成的墩身，所述钢筋混凝土墩柱上节段和钢管混凝土芯柱预制为一体并插入承台预留的杯槽中，所述预制空心薄壁钢桥墩下节段与钢筋混凝土墩柱上节段及承台之间均通过高强螺栓连接。结构受力明确，传力可靠，且具有遭遇强震作用损坏后可更换节段、快速恢复功能的特性，解决了传统预制拼装桥墩耗能能力较差、震损后难以修复等问题。
