Reinforcing steel bar sleeve grouting equipment and grouting method

The invention belongs to the technical field of grouting devices, particularly discloses reinforcing steel bar sleeve grouting equipment and a grouting method, and solves the problem that grouting is not full due to the fact that bubbles are defoamed in a grouting sleeve. Comprising a foundation, a supporting plate and a prefabricated plate, a plurality of grouting sleeves are arranged in the prefabricated plate, and a steel bar body is arranged in each grouting sleeve. Air is exhausted into the second pipeline through the output end of an air compressor in the pushing mechanism, and concrete slurry is pushed to one end of the discharging port through a piston pushing block on the premise that contact between the concrete slurry and air is not increased, so that the content of air in the concrete slurry is reduced. Concrete is stirred and fed in a vacuum environment, so that the content of air in concrete slurry is reduced, the falling height of the concrete slurry in the sleeve after filling is reduced, the
