The invention discloses a bionic agitator for injection grout and a hybrid power bionic agitating system. The bionic agitator for slip casting comprises an agitating barrel with a feed port and a grout outlet pipe, and the bottom face of the agitating barrel is an oblique face inclining towards the grout outlet pipe. A power part is fixedly arranged at the upper end of the agitating barrel through a supporting frame, the power output end of the power part is connected with an agitating shaft in the agitating barrel, and a plurality of agitating blades are perpendicularly or obliquely arranged on the agitating shaft. When the agitating blades are obliquely arranged on the agitating shaft, the inclination directions of the agitating blades are opposite to the turning direction of the agitating shaft. A plurality of bionic non-smooth units are arranged on the inner surface of the agitating barrel and the agitating blades, the superficial area of faces, making contact with the agitating barrel, of all the bionic non-smooth units on the agitating barrel is 20%-50% of the superficial area of the inner surface of the agitating barrel, and the superficial area of faces, making contact with the agitating blades, of all the bionic non-smooth units on the agitating blades is 20%-60% of the superficial area of all the surfaces of the agitating blades. The bionic agitator for the injection grout has the beneficial effects of being environmentally friendly, efficient and the like.
