The invention discloses a gradient conveying stacked part separation method, and relates to the field of automatic control and logistics sorting. On the basis of a horizontal distance between a stacked package marked by an image recognition algorithm and a previous package, vertical fall between a front conveying unit and a rear conveying unit in gradient conveying is utilized, and on the basis of controlling the speed difference of the front conveying unit and the rear conveying unit in real time, vertical stacked part separation is achieved, and the hidden dangers of collision to the previous package and stacked part re-formation are avoided; and a good premise and foundation are created for single-piece queuing operation of subsequent packages in the horizontal direction. According to the gradient conveying stacked part separation method, for stacked parts recognized on belt conveying units, separation of the stacked parts is achieved on the basis of distance control of the stacked parts falling to the previous belt conveying unit through vertical fall by dynamically adjusting the speed difference between the two adjacent belt conveying units.

The present invention discloses a repair structure for a scour pit of an underwater foundation structure, including a scour pit foundation solidification structure, a scour pit backfill solidification structure and an anti-scour protection solidification structure. The scour pit foundation solidification structure is a plurality of solidified soil piles driven into the bottom surface of the scour pit and the outer seabed of the scour pit; the scour pit foundation solidification structure is connected to the underwater foundation structure through a curing agent; the scour pit backfill solidification structure is solidified soil blown into the scour pit, and the top elevation of the scour pit backfill solidification structure is the seabed surface elevation; the anti-scour protection solidification structure is solidified soil blown into the top surface of the scour pit backfill solidification structure, and the top surface of the anti-scour protection solidification structure is 80 cm higher than the top surface of the scour pit, and the distance from the outer edge of the bottom surface to the edge of the scour pit is 0.5 times the diameter of the scour pit. The present invention also discloses a repair method for a scour pit of an underwater foundation structure. The present invention can effectively repair the scour pit that has been formed and prevent the scour pit from forming again.
