The high-strength municipal viaduct steel box girder construction cast-in-place device comprises a steel box body, a cover plate is arranged on the surface of the top of the steel box body, a limiting bolt is connected to the surface of the top of the cover plate in a penetrating and threaded mode, an inner cavity of the steel box body is fixedly connected with an isolation plate, and a supporting steel rod is welded to the surface of the front side of the isolation plate in a penetrating mode. A first cooling pipe is fixedly connected to the bottom of an inner cavity of the steel box body, and a first water inlet pipe is arranged on one side of the first cooling pipe. The steel box has the beneficial effects that the isolation plate and the supporting steel rods are arranged, the isolation plate divides the inner cavity of the steel box body, when concrete is cast in place in the steel box body, the concrete cannot be excessively dispersed, and the phenomenon that the steel box body topples over due to uneve
