The invention discloses a rapid pile connecting structure, a prefabricated pile and a method. The problems that in the prior art, connecting structures of adjacent prefabricated piles are complex, and stress concentration exists are overcome. The provided rapid pile connecting structure is simple and convenient to operate, and properties of the multi-section connected prefabricated pile in various aspects are effectively improved. The rapid pile connecting structure comprises connecting pieces, connecting ribs and fasteners, wherein the connecting pieces are arranged between an upper pile joint and a lower pile joint and are connected with the upper pile joint and the lower pile joint in a fastening manner. The connecting ribs penetrate the connecting pieces, and the two ends of the connecting ribs are connected with the upper pile joint and the lower pile joint correspondingly. The fasteners are arranged on the connecting ribs so as to lock the connecting pieces and the connecting ribs.
