The utility model discloses a grouting sealing device for
subgrade engineering, which comprises a case, a cover plate is arranged on one side of the outer surface of the upper end of the case, a material mixing structure and a grouting pump are arranged in the case, the material mixing structure comprises a material mixing cylinder, a support frame, a speed reducing motor, a rotating shaft and a stirrer, and two sets of connecting arm rods are fixedly installed at the upper end and the lower end of the outer surface of one side of the rotating shaft, a scraping plate is fixedly installed between the two sets of connecting arm rods, a
silica gel plate is fixedly installed on the outer surface of one side of the scraping plate, and a grouting valve is connected to the outer surface of one end of the grouting pump. According to the grouting and seam sealing device for the roadbed
engineering, through the arrangement of the scraping plate and the
silica gel plate, the inner wall of the mixing
barrel can be conveniently scraped, materials are prevented from being attached to the inner wall of the mixing
barrel, the cleaning difficulty is reduced, through the arrangement of the damping structure, the buffering and damping effects can be achieved, and the service life of the device is prolonged.
