The invention discloses a hoisting process for a general section of a warehouse deck of an orange juice ship, which comprises the following process steps of: dividing the general section of the warehouse deck into six deck sections, and combining the general section to form a large ring seam at a deck surrounding a hatch; measuring each deck section, calculating the weight and gravity center position of each deck section, and designing a hoisting point position according to the gravity center position; fixedly arranging a reinforcing structure at the back of the hoisting point of the deck section, and turning over the deck sections; fixedly arranging a hoisting lug at the hoisting point on the front side of each deck section; hoisting the deck sections by adopting a floating crane to rightabove the installation position on the deck surrounding the hatch, using an auxiliary precise landing limit tooling on the deck surrounding the hatch to hoist the deck sections without margins and landing the deck sections to the installation position on the deck surrounding the hatch; according to the invention, the general section of the warehouse deck is divided into six deck sections for construction, so that the problems of narrow construction space and difficult construction of workers due to the fact that the section of the warehouse deck of the orange juice ship is installed after tank bodies enter the warehouse are solved; and hoisting without margins can be achieved.
