Single-column pier bridge integrated reinforcing structure and construction method
The invention relates to a single-column pier bridge integrated reinforcing structure which comprises a foundation reinforcing system, a column body reinforcing system and an anti-seismic and anti-overturning reinforcing system, the foundation reinforcing system comprises a bottom steel hoop and a steel pipe pile, and the column body reinforcing system comprises a reinforced concrete layer, a middle steel hoop, a steel strand and a top steel hoop. The anti-seismic and anti-overturning reinforcing system comprises a damper, and the damper is connected with the bridge body and the top steel hoop through a hinge device. Through reinforcement from bottom to top, the foundation, the column body and the pier head form a whole, and the three reinforcement parts are linked with one another, so that the bearing capacity of the pier foundation is improved, meanwhile, the shear resistance, compression resistance and torsion resistance of the pier column body are improved, and the situation that a bridge is damaged due to stress concentration at weak parts after single reinforcement is avoided; therefore, the anti-seismic and anti-overturning capacities of the bridge are effectively improved; and the steel strands are tensioned in a surrounding manner, and concrete is sprayed on the surfaces of the steel strands to form a hoop effect, so that the shear resistance, compression resistance, torsion resistance and other capabilities of the column body are improved.
本发明涉及一种独柱墩桥梁一体化加固结构，包括基础加固系统、柱身加固系统和抗震抗倾覆加固系统，基础加固系统包括底部钢套箍和钢管桩，柱身加固系统包括钢筋混凝土层、中部钢套箍、钢绞线和顶部钢套箍，抗震抗倾覆加固系统包括阻尼器，阻尼器通过铰接装置分别与桥梁主体和顶部钢套箍连接。通过从下至上的加固，从基础、柱身、到桥墩头都形成一个整体，且这三者加固环环相扣，提高了桥墩基础的承载能力，同时提高了桥墩柱身的抗剪、抗压及抗扭能力，避免单一加固后，桥梁在薄弱部位应力集中而发生破坏，从而有效提高桥梁的抗震、抗倾覆能力；钢绞线进行环绕张拉，并于表面喷射混凝土，形成环箍效应，从而提高柱身的抗剪、抗压及抗扭等能力。
