The invention discloses a lifting and turning-over method for an aluminum ship hull of a ship, belongs to the technical field of ship hull lifting and turning-over, and solves the technical problems of long construction period and high labor cost of an existing lifting and turning-over scheme. The method comprises the following steps: welding an aluminum alloy hanger to a ship body for lifting and turning over, specifically, segmenting the aluminum ship body of the ship; determining a lifting and turning-over mode, arranging an aluminum alloy hanger, selecting an aluminum alloy hanger form, analyzing the strength of a lifting point position, and determining a lifting reinforcing form; the hoisting point area is reinforced before hoisting and turning over; welding an aluminum alloy hanger, checking the internal quality of a welding seam, and making mark points around the aluminum alloy hanger; hoisting and turning over the segmented ship body; checking the internal quality of a welding seam and the deformation condition of peripheral plates after hoisting and turning; and the form of the aluminum alloy hanger or the hanging point position or the reinforcing form is improved. And the aluminum alloy hangers are used for hoisting and turning over, so that the ship body building efficiency can be greatly improved, manpower and material resources are reduced, and benefits are improved.
