The invention discloses adouble-liquid stirring grouting systemwhich comprises rotatable slurry channel switching components, wherein the rotatable slurry channel switching components rotate so as to grout slurry through grouting channels; through switching of the rotatable slurry channel switching components, twotypes of slurry can be separately and simultaneously grouted into a drilling rod which rotates continuously; the slurry is conveyed to the drill bit through a grouting channel inside the drilling rod; the two grouting channels are in a tube bundle mode, so thatthe cross section rigidity is veryhighto avoiddistortion, the pressure is stabilized within a certain fluctuation range to continuously grout the two types of slurry into a soil layer, the slurry is ejected out from ejection holes in the drill bit, and under the continuous stirring of the stirring blades of the drill bit, the two types of slurry are sufficiently and uniformly mixed. The strength of a column body is improved as the two types of slurry are cured and formed through rapid chemical reaction, so that the double-liquid stirring grouting system is applicable to grouting systems of pile machines such as ordinary stirring pile machines, bidirectional stirring pile machines, double-tube multi-directional stirring pile machines, and has wide applicability.
