Detachable bridge pier reinforcing and anti-collision integrated structure and construction method thereof
The invention provides a detachable bridge pier reinforcing and anti-collision integrated structure and a construction method thereof, and belongs to the field of bridge pier reinforcing, repairing and anti-collision. The problems that when an existing pier is reinforced, the occupied space is large, the reinforced section reliability is low, the safety is relatively poor, the replacement efficiency is low, and the durability is poor are solved. The anti-collision structure comprises a steel reinforcement framework, an inner-layer splicing corrugated steel pipe and an outer-layer splicing corrugated steel pipe which are sequentially arranged outside an existing reinforced concrete pier in a surrounding mode, an inner-layer reinforcing layer is arranged between the inner-layer splicing corrugated steel pipe and the existing reinforced concrete pier, and an outer-layer anti-collision layer is arranged between the inner-layer splicing corrugated steel pipe and the outer-layer splicing corrugated steel pipe. The inner-layer spliced corrugated steel pipe comprises a plurality of inner-layer corrugated steel plates which are connected through inner-layer connecting parts, and the outer-layer spliced corrugated steel pipe comprises a plurality of outer-layer corrugated steel plates which are connected through outer-layer detachable connecting parts. The energy-dissipating and energy-dissipating composite wall has the advantages of being high in functionality, good in stress performance, high in energy-dissipating capacity, excellent in durability, convenient to construct, high in replaceability and capable of saving cost.
本发明提供一种可拆卸的桥墩加固与防撞一体化结构及其施工方法，属于桥墩加固修复与防撞领域。为解决现有桥墩在加固时所占空间大、加固截面可靠性低、安全性相对较差、可更换效率低以及耐久性差等问题。本发明包括在既有钢筋混凝土桥墩外依次围设的钢筋骨架、内层拼接波纹钢管和外层拼接波纹钢管，内层拼接波纹钢管与既有钢筋混凝土桥墩间设有内层加固层，内层拼接波纹钢管与外层拼接波纹钢管之间设有外层防撞层，内层拼接波纹钢管包括通过内层连接部连接的若干个内层波纹钢板，外层拼接波纹钢管包括通过外层可拆卸连接部连接的若干个外层波纹钢板。具有功能性强、受力性能好、耗能能力强、耐久性优异、施工便捷、可更换性强且可节省成本的优势。
