Full-automatic grouting equipment for bridge

The invention discloses bridge full-automatic mud jacking equipment which comprises a base plate, four supporting legs, four first hydraulic cylinders and four universal wheels, the four supporting legs are installed on the lower wall face of the base plate, the four first hydraulic cylinders are installed on the lower wall face of the base plate, and the four universal wheels are installed at the telescopic ends of the four first hydraulic cylinders correspondingly. And a mud jacking structure is arranged on the base plate. When cement needs to be added into the material storage box, the second hydraulic cylinder extends to enable the material storage box to move downwards in an inclined mode, feeding is convenient, an operator does not need to lift the cement to a high position, the distance between the cement and the mouth and the nose of the operator is not increased, the safety coefficient is increased, and the health of the operator is guaranteed; the metal bars collect heat and transfer heat to water,
