Prefabricated assembled pier with replaceable parts and construction method thereof
The invention relates to a prefabricated assembled pier with replaceable parts and a construction method thereof. The prefabricated assembled pier with the replaceable parts is characterized by comprising a bearing platform with a reserved cup opening foundation and a prefabricated concrete-filled steel tube pier body inserted into the reserved cup opening foundation, an embedded steel plate is arranged at the bottom of the bearing platform cup opening foundation, thereby satisfying a requirement for partial pressure bearing of the prefabricated steel tube concrete pier bottom; a plurality of high-strength connecting lug plates are welded to the portion, located above the bearing platform, of the bottom section of the prefabricated concrete-filled steel tube pier body, and the high-strength connecting lug plates are connected with replaceable anchoring-connecting assemblies through high-strength bolts, and the replaceable anchoring-connecting assembly is connected with an anchoring bottom steel plate pre-buried in the bearing platform through a high-strength bolt; the structure design is simple, the structure stress is clear, it can be guaranteed that the pier column has enough strength, rigidity and energy dissipation capacity, and the prefabricated assembled pier has the advantages that the pier column can be replaced after being damaged by the strong earthquake effect, and the function can be rapidly recovered.
本发明涉及一种可更换部件的预制拼装桥墩及其施工方法，其中可更换部件的预制拼装桥墩，其特征在于：包括具有预留杯口基础的承台和插入预留杯口基础的预制钢管混凝土墩身，所述承台杯口基础的底部设置有预埋钢板，以满足预制钢管混凝土墩底局部承压的需要，所述预制钢管混凝土墩身在位于承台上方的底部节段焊接若干个高强连接耳板，所述高强连接耳板与可更换的锚固‑连接组件通过高强螺栓连接，所述可更换的锚固‑连接组件与承台内预埋的锚固底钢板通过高强螺栓连接；本发明构造设计简单，结构受力明确，可以保证墩柱具有足够的强度、刚度和耗能能力，且具有遭遇强震作用损坏后可更换、可快速恢复功能的特性。
