Rapid reinforcing structure for pier damaged by earthquake and construction method
The earthquake damage pier rapid reinforcing structure comprises a pile, and a steel hoop Z is arranged from the top of the pile to the bottom of a concrete filled steel tubular column in a sleeving mode; the concrete filled steel tubular columns are arranged at the top of the steel hoop Z in the circumferential direction; the center of the concrete-filled steel tubular column is provided with an embedded corrugated pipe during prefabrication, and a steel hoop J sleeving the column is arranged on the concrete-filled steel tubular column; reinforcing steel bars with two ends anchored by nuts are arranged in the corrugated pipe, the preformed hole Z of the steel hoop Z and the preformed hole J of the steel hoop J in a penetrating manner. The prefabricated concrete-filled steel tubular columns are connected with the steel hoops J and the steel hoops Z into a whole through the reinforcing steel bars, installation and rapid construction are convenient, the concrete-filled steel tubular columns prefabricated according to different column diameters have the advantage of assembly type rapid construction, and the pier damaged by the earthquake can be rapidly reinforced. Meanwhile, a complete, effective and unique construction scheme is provided for rapid reinforcement of the earthquake-damaged pier, reinforcement of the damaged column is achieved, and the purpose of rapid reinforcement of the earthquake-damaged pier is achieved.
一种地震损伤桥墩快速加固结构及施工方法，包括桩，桩顶部至钢管混凝土柱底部套设有钢抱箍Z；钢管混凝土柱沿周向布置在钢抱箍Z顶部；钢管混凝土柱中心布设有预制时的预埋的波纹管，钢管混凝土柱之上布置有套设于柱上的钢抱箍J；波纹管、钢抱箍Z的预留孔Z及钢抱箍J的预留孔J中穿设有两端由螺母锚固的加固钢筋。采用预制的钢管混凝土柱由加固钢筋与钢抱箍J和钢抱箍Z连接为一体，便于安装及快速施工，按照不同柱直径预制好的钢管混凝土柱，具备了装配式快速施工的优点，使得地震损伤桥墩能得到快速加固。同时，本发明为地震损伤桥墩的快速加固提供了一套完整、有效、独特的施工方案，实现对损伤柱的加固，达到快速加固地震损伤桥墩的目的。
