Filling pile bottom dreg cleaning equipment and dreg cleaning method adopting same

The invention discloses filling pile bottom dreg cleaning equipment and a dreg cleaning method adopting the same, and relates to the technical field of building construction. The dreg cleaning equipment comprises a dreg storage pool, a conical barrel and a check plate, wherein the dreg storage pool comprises an outer cylindrical barrel; an upper opening of the conical barrel is small, and a lower opening of the conical barrel is big; the check plate is hinged to one side of the upper opening of the conical barrel and can cover the upper opening of the conical barrel; the whole conical barrel is arranged on the inner side of the outer barrel of the dreg storage pool; and the dreg storage pool further comprises at least one layer of dreg storage board capable of being positioned between the inner wall of the outer barrel and the outer wall of the conical barrel. The dreg cleaning method adopting the filling pile bottom dreg cleaning equipment comprises the following steps that the dreg cleaning equipment is hoisted to the bottom of a filling pile hole; the check plate is automatically opened under the action of buoyancy, and dregs at the hole bottom flow to the position above the dreg storage pool through the upper opening of the conical barrel; the dreg cleaning equipment is subjected to standing for five to eight minutes; the dreg cleaning equipment is slowly lifted upwards, the dregs sink on a dreg storage plate of the dreg storage pool, and the dregs deposited in the dreg storage pool are cleaned up; and the above steps are executed again until the dregs at the bottom of the filling pile hole are cleaned up thoroughly.
