Integral bridge reinforcing device

The invention discloses an integral bridge reinforcing device which comprises a beam body. The bottom surface of the beam body is fixedly connected with a buffer plate; the bottom surface of the buffer plate is fixedly connected with a buffer spring; the other end of the buffer spring is fixedly connected with a bearing table; a pier is fixedly connected with the bottom face of the bearing table;two bearing columns are fixedly connected with the bottom face of the bearing table; two first inclined supporting beams are fixedly connected with the bottom face of the bearing table; two reinforcing columns are fixedly connected with the outer surface of the pier; and a fourth inclined supporting beam is fixedly connected with the upper surface of each reinforcing column. According to the integral bridge reinforcing device, by arranging the buffer plate and the buffer spring, when the bridge floor is vibrated and jolted, vibration buffering can be conducted on the bridge floor, a triangularstructure is formed among
