Pier circumferential reinforcing structure and reinforcing method
The invention discloses a bridge pier circumferential reinforcing structure and method. The bridge pier circumferential reinforcing structure comprises a prestressed tendon annularly wound around the periphery of a bridge pier, anchor clamps anchored and clamped at the two ends of the prestressed tendon, and an adjustable supporting frame arranged between the bridge pier and the prestressed tendon. The adjustable supporting frame comprises a base, an adjusting mechanism and a supporting rod connected with the base through the adjusting mechanism. The bottom end face of the base abuts against the outer side face of the pier, and the axial direction of the supporting rod is the same as the direction of supporting force applied to the bottom end face by the pier. One end of the supporting rod is connected with the base through an adjusting mechanism, and the other end of the supporting rod is provided with a supporting part used for supporting prestressed tendons. The adjusting mechanism is used for adjusting the distance between the base and the supporting part in the axial direction of the supporting rod. According to the bridge pier circumferential reinforcing structure and method, the circumferential reinforcing effect can be improved, the surface of the bridge pier is prevented from being damaged, large tensioning equipment does not need to be adopted, cost is low, and the technology is simple.
本发明公开了一种桥墩环向加固结构及加固方法，包括环向缠绕于桥墩外周的预应力筋、锚夹于预应力筋两端的锚夹具、布设于桥墩与预应力筋之间的可调节支撑架；所述可调节支撑架包括底座、调节机构、与底座通过调节机构连接的支杆；所述底座的底端面与桥墩的外侧面抵接，所述支杆的轴向与桥墩施加给底端面的支撑力方向相同；所述支杆的一端通过调节机构与底座连接、另一端设有用于支撑预应力筋的支撑部；所述调节机构用于调节底座与支撑部沿支杆轴向的间距。本发明公开的一种桥墩环向加固结构及加固方法，能够改善环向加固效果，避免破坏桥墩表面，无需采用大型张拉设备，成本较低、工艺简单。
