Rapid reinforcing device and method after transverse damage of bridge pier

The rapid reinforcing device comprises two hoops and a transverse connecting piece, the inner diameter of the hoops is larger than the outer diameter of the bridge pier, and when the hoops are arranged on the bridge pier in a sleeving mode, a space used for irrigating a high-strength grouting material is formed between the hoops and the bridge pier; the two ends of the transverse connecting piece are connected to the two hoops respectively. According to the method, the hoop, the transverse connecting piece and the high-strength grouting material are adopted to complete rapid reinforcement after the bridge pier is transversely damaged, the newly-added hoop, the transverse connecting piece and the high-strength grouting material are small in size and light in weight, and the influence of the increased load on the bearing capacity of the foundation is small; the newly-added components can be machined in a factory and installed on site, and the structure is light, so that the damaged bridge pier can be rapidly re
