The invention discloses pile hole capping mass hole cleaning equipment and a pile hole capping mass treatment method by adopting the equipment. The hole cleaning equipment comprises a movable machinebody, a telescopic large arm, a vertical arm and a working pipe arm. A rotary hole cleaning disc is arranged on the working pipe arm, spiral transmission blades are arranged in the working pipe arm, arotary cutter blade is arranged on the rotary hole cleaning disc, and a feeding cavity is formed in the rotary hole cleaning disc. The capping mass treatment method comprises the steps that the rotary hole cleaning disc is rotated to amend the hole wall, and the rotary hole cleaning disc is placed down to the bottom end of a pile hole; the rotary hole cleaning disc is rotated to convey capping mass upwards, the rotary hole cleaning disc is placed down continuously, the contacted earthwork is conveyed upwards, till the position of the rotary hole cleaning disc is lower than a designed elevation of the pile hole; and after the capping mass at the bottom end of the pile hole is cleaned up, the rotary cutter blade is rotated to seal a soil inlet, the rotary hole cleaning disc is moved out toopen the soil inlet, and the spiral transmission blades are rotated reversely to make the earthwork fall down. By adopting the device, the capping mass at the bottom end of the pile hole can be effectively cleaned, the strength of the end of a pile foundation is improved, and the force bearing stability is improved.
