Concrete-filled steel tube pier with corrugated sleeves and resettable double column piers and construction method thereof
The invention provides a concrete-filled steel tube pier with corrugated sleeves and resettable double column piers and a construction method thereof, the concrete-filled steel tube pier comprises a cover beam, at least two column piers and a bearing platform which are sequentially arranged from top to bottom, a prestress positioning piece sequentially penetrates through the cover beam, the column piers and the bearing platform, and a corrugated steel coupling beam is arranged between the two column piers. The concrete-filled steel tube pier is reasonable in design and simple in structure, the bearing capacity and corrosion resistance of the pier are improved, the construction period is shortened, vibration transmitted from the lower portion of a bridge is relieved, earthquake energy is absorbed, damage to the capacity borne by the column limbs is reduced, and post-earthquake resettable of the column piers is achieved.
本发明提供一种带波纹套管可复位双柱墩的钢管混凝土桥墩及其施工方法，包括由上至下依次设置的盖梁、至少两个柱墩以及承台，预应力定位件依次贯穿盖梁、柱墩以及承台，两个柱墩之间设置有波纹钢连梁。本发明设计合理，构造简单，提高桥墩的承载力和耐腐蚀性，缩短施工工期，减轻由桥下传来的振动，吸收地震能量，减小柱肢所承受的能力损伤，实现柱墩的震后可复位。
