The invention discloses a construction method for transferring and boarding an ultra-wide framing
steel jacket box. The construction method comprises the steps that 1, a transport ship is berthed along the
shore and tied, a
deck is cleaned, and a ship body structure influencing roll-on and roll-off is dismantled; 2, planning a walking
route of the module vehicle on the
deck, and
welding buttresses to support the
steel jacket box; 3, the first casing box is transported to a
wharf on land through a module vehicle; 4, the transport ship is vertically berthed to the
wharf in cooperation with tugs, and a T-shaped berthing fixing
system is constructed; step 5, paving a ship-
shore channel from the
wharf to the transport ship by taking the high and flat tide as an operation
window period; adjusting
ballast water of the transport ship to maintain the ship-
shore height difference not greater than a critical value; the module vehicle transports the first casing box to the transport ship; sixthly, the height of the module vehicle is reduced so that the in-place first casing box can be unloaded to the
buttress; the module vehicle returns to the land; seventhly, an anti-sliding
system of the first casing box is installed; and (8) according to the construction
modes of the step (3), the step (5) and the step (7), the second casing box is rolled on the transport ship.
