The invention discloses grooving equipment for an air-entrapping concrete block wall and belongs to the field of construction equipment. According to the technical scheme, the grooving equipment comprises an L-shaped shell body. A drilling shaft penetrates through the internal vertical portion of the shell body. A drill is arranged at the bottom end of the drilling shaft and stretches out of the bottom end of the vertical portion of the shell body. A protective cover is arranged on the outer side of the drill. A lifting handle is arranged on the upper side of the horizontal portion of the shell body. A handle is arranged on the vertical portion of the shell body, and the handle penetrates through the shell body to be connected with the upper portion of the drilling shaft. A motor is arranged in the horizontal portion of the shell body, and an output shaft of the motor is in linkage connection with the drilling shaft through a bevel gear set. The grooving equipment for the air-entrapping concrete block wall has the beneficial effects that the design is reasonable, the structure is simple, the effect of water blast dust falling is achieved, environment protection is better achieved, the grooving equipment is special for limiting, and the problem that a semicircular groove is used for mounting a round pipe is solved.
