The method for controlling the overall segment loading precision of the ultra-high type compartment according to claim 1, wherein in the fifth step, the concrete steps of monitoring the change of the verticality of the compartment (1) and adjusting the assembly work in real time by combining the plumb (6) with the front wall inspection line (71) during the assembly process include: when the compartment (1) is inclined forwards, the assembly of the front wall is stopped, the assembly of the rear wall is continued, and after the verticality of the compartment (1) is restored, the front wall and the rear wall are synchronously assembled; when the compartment (1) is inclined backwards, the assembly of the rear wall is stopped, the assembly of the front wall is continued, and after the verticality of the compartment (1) is restored, the front wall and the rear wall are synchronously assembled.
8. The method for controlling the overall segment carrying precision of the ultra-high type compartment according to claim 1, wherein in the sixth step, the specific steps of monitoring the perpendicularity change of the compartment (1) and adjusting the welding work in real time by combining the plumb (6) with the front wall inspection line (71) during the electric welding process include: when the compartment (1) is inclined forwards, the electric welding of the front wall is stopped, the electric welding of the rear wall is continued, and after the verticality of the compartment (1) returns, the electric welding is carried out on the front wall and the rear wall synchronously; when the compartment (1) is inclined backwards, the electric welding of the rear wall is stopped, the electric welding of the front wall is continued, after the verticality of the compartment (1) returns, the electric welding is synchronously carried out on the front wall and the rear wall, and finally, the post-welding verticality state meets the precision requirement.
9. A ship comprising a bulkhead block mounted on a hull according to the mounting accuracy control method of any one of claims 1 to 8.
