The invention discloses a filling pile construction scheme and a funnel thereof. The filling pile construction scheme is characterized in that an outlet is formed in the bottom of a funnel body, a sphere which is located in the outlet and adapts to the funnel body is lifted in the funnel body, a lifting rope which is fixed to the sphere is arranged on the sphere, a block is fixed to one end, whichis far from the sphere, of the lifting rope, cross rods are arranged on the top of the funnel body, the cross rods include a fixed rod and a movable rod, a gap which is used for the lifting rope to pass through is formed between the ends of the fixed rod and the movable rod, the width of the gap is less than the block, a vertical guide groove is formed in the funnel body, a floating block is arranged in the guide groove, and a linking mechanism which is used for linking one end, which is close to the fixed rod, of the movable rod to move away when the concrete level in the funnel body reachesthe preset height is arranged on the floating block; concrete is continuously added to the funnel body, the concrete level in the funnel body continuously rises, the floating block continuously movesupwards until the level rises to the preset height, and then the end of the movable rod is linked to move away, so that the block falls off; and at the moment, the sphere and concrete are dischargedfrom the outlet together, and the lifting rope does not need to be manually sheared off, so that the operation is convenient.
