Self-resetting concrete-filled steel tube fabricated bridge pier wrapped with constraint RC and construction technology of self-resetting concrete-filled steel tube fabricated bridge pier
The invention discloses a self-resetting concrete-filled steel tube fabricated bridge pier wrapped with constraint RC and a construction technology thereof. The technology comprises the following steps that (1) a foundation is poured, the lower end of a pre-buried pipe is pre-buried in the foundation, a steel strand penetrates through the pre-buried pipe, and the lower end of the steel strand is anchored to the foundation; and (2) the embedded pipe is sleeved with a connector of the pier column bottom reinforcing plate and the steel pipe, and the connector is installed in place. And (3) the lower end of the steel pipe is sleeved with a pier foot wrapping pipe, and post-pouring concrete at the pier foot is poured. And 4) pouring concrete in the steel pipe from the top of the steel pipe, and reserving a cavity with a set length at the upper end of the steel pipe. And (5) a plurality of anchoring steel bars on the prefabricated cover beam are inserted into the steel pipes, and concrete is filled through the reserved wet operation pouring holes. And (6) the steel strand is tensioned and anchored. The fabricated pier is high in construction speed, good in bearing capacity and high in energy dissipation capacity and self-resetting capacity.
本发明公开了一种外包约束RC的自复位钢管混凝土装配式桥墩及其施工工艺，该工艺包括以下步骤：1)浇筑基础，预埋管下端预埋在基础内，钢绞线穿过预埋管，钢绞线下端与基础锚固；2)墩柱底部加强板和钢管的连接体套在预埋管上并安装到位。3)在钢管的下端套设墩脚外包管，并浇筑墩脚处后浇混凝土。4)从钢管的顶部浇筑钢管内混凝土，并在钢管的上端预留设定长度的腔体。5)将预制盖梁上的若干锚固钢筋插入钢管，通过预留湿作业浇筑孔填充混凝土。6)张拉钢绞线并锚固好。本发明所述装配式桥墩的施工速度快，并且有着良好的承载能力，有着较高耗能能力和自复位能力。
