The invention provides a concrete protective film laying device. The concrete protective film laying device comprises a laying trolley and a fixing pile, wherein the rear end of the laying trolley isrotatably provided with a rotary shaft for placing a film roll, and is further provided with a driving clamping discharging roller and a driven clamping discharging roller; the driving clamping discharging roller is connected to a servo motor; the servo motor is connected to a controller; and a plurality of photoelectric sensors for monitoring the rotation speed of a roller are further arranged ona rack. While the laying device is used, one end of a film is fixed through the fixing pile, the servo motor drives the driving clamping discharging roller and the driven clamping discharging rollerto outwards convey the film continuously; and moreover, the motion speed is further monitored through the photoelectric sensors, so that the film releasing speed is consistent with the motion speed ofthe laying trolley. Compared with the prior art, the concrete protective film laying device has the advantages of improving the laying efficiency, being not liable to have folds, and being high in laying quality.
