The invention discloses a bored pile construction method for reinforcing cage framework layered installation. The bored pile construction method for reinforcing cage framework layered installation comprises the steps of (a) making preparation for construction, (b) setting out a pile position, (c) manufacturing a pile casing and pre-burying the pile casing, (d) drilling a bore, (e) reinforcing a dado, (f) cleaning the bore for the first time, (g) manufacturing reinforcing cage frameworks and installing the reinforcing cage frameworks in a layered mode, (h) placing a guide tube, (i) cleaning the bore for the second time, (j) pouring concrete, (k) recycling the pile casing and (l) backfilling the pile bore. According to the bored pile construction method for reinforcing cage framework layered installation, the reinforcing cage frameworks are placed in the bore in a layered mode, aligned one by one and welded, so that a reinforcing cage is installed, and a traditional method that the reinforcing cage is directly installed is replaced; the reinforcing cage can be stably placed in the bore, and the reinforcing cage is prevented from colliding against the wall of the bore and prevented from deforming; in addition, the reinforcing cage can be accurately located to the center of a bore site, and the reinforcing cage is prevented from floating or sinking in the process of concrete pouring. Besides, by the adoption of the bored pile construction method for reinforcing cage framework layered installation, the speed is high, a construction period is short, and the quite high scientific performance and the feasibility are achieved.
