Pile and column integrated prefabricated bridge lower structure and construction method thereof
The invention provides a pile and column integrated prefabricated bridge lower structure and a construction method thereof. The bridge lower structure comprises a prefabricated bent cap and a prefabricated tubular pile, and a preformed hole and a preformed grouting hole which communicate with each other are formed in the bottom of the prefabricated bent cap; the tops of the prefabricated tubular pile is inserted into the preformed hole, and the prefabricated tubular pipe and the prefabricated bent cap are connected through corrugated pipe grouting; the bottom of the prefabricated tubular pileis inserted into an embedded hole formed in the ground in advance and is fixedly connected with cement stirring soil. The prefabricated tubular pile comprises at least two sections of tubular pile bodies which are sequentially arranged in the length direction of the prefabricated tubular pile, every two adjacent sections of tubular pile bodies are connected through a connecting structure, a plurality of reserved steel bars are arranged at the top of the prefabricated tubular pile body and connected with main bars in the prefabricated tubular pile body, and the reserved steel bars are located in the corrugated pipe. According to the bridge lower structure, construction of the fabricated bridge substructure can be rapidly achieved, site occupation is reduced, and based on the construction method provided by the bridge lower structure, the construction efficiency can be improved, and site occupation is reduced.
本发明提供一种桩柱一体化预制装配桥梁下部结构及其施工方法，其中，桥梁下部结构包括预制盖梁和预制管桩，预制盖梁的底部设置相互连通的预留孔和预留注浆孔；预制管桩的顶部插设预留孔中，预制管桩和预制盖梁采用波纹管灌浆连接；预制管桩的底部插设至地面预先开设的预埋孔中，并通过水泥搅拌土固连，预制管桩包括至少两节段管桩，所有节段管桩沿其长度方向依次设置，相邻两节段管桩之间通过连接结构相互连接，预制管桩的顶部设置有若干预留钢筋，预留钢筋与预制管桩内的主筋相连，预留钢筋位于波纹管内；该桥梁下部结构可快速的实现装配式桥梁下部结构施工、减少场地占用，基于该桥梁下部结构所提出的施工方法，可提高施工效率、降低场地占用。
