This invention belongs to the field of steel pipe pile driving technology, specifically relating to a method for reducing pile slippage during the driving of large steel pipe piles. The method involves arranging 3-5 layers of geogrid along the vertical direction on the inner wall of the steel pipe pile, with a spacing of 6-10m between adjacent geogrids and a distance of 6-10m between the lowest geogrid and the lower end face of the steel pipe pile. By setting geogrids on the inner wall of the steel pipe pile, the additional resistance provided by the geogrids effectively slows down the pile's penetration speed, inhibits the continued acceleration of pile slippage, and thus reduces the risk of major safety accidents such as severe shaking of the hammer system, instability of the crane vessel, wire rope breakage, or even the hammer falling into the sea due to uncontrolled rapid sinking of the pile. This significantly improves the safety of construction personnel and equipment.
