Method for assembling corrugated bulkhead block

Abstract

The invention relates to the shipbuilding field, and particularly discloses a method for assembling a corrugated bulkhead block. The method comprises the following steps: hoisting a deck subsection to an overturning area, and making the reverse side thereof face upward; hoisting the corrugated bulkhead subsection to the deck subsection, and fixedly connecting the corrugated bulkhead subsection on the reverse side of the deck subsection to form the corrugated bulkhead block; and overturning the corrugated bulkhead block and hoisting the corrugated bulkhead block to a dock / shipbuilding platform. According to the method, the assembly of the corrugated bulkhead block is completed at the overturning area, and then the corrugated bulkhead block is hoisted to the dock / shipbuilding platform. The method has the advantages that a large quantity of hoisting and welding work is completed at the overturning area, so that the operation in a closed compartment is avoided, and the safety factor of the operation is improved; horizontal overhead position welding is transformed into flat fillet welding in the assembling process, so that the welding quality is improved; and the times of repeatedly hoisting the corrugated bulkhead subsection and the deck subsection to the dock / shipbuilding platform are reduced, thereby being favorable for assembling the corrugated bulkhead block quickly, and shortening the manufacturing cycle of the dock / shipbuilding platform.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a method for assembling the general section of a grooved bulkhead. Background technique [0002] Conventional product oil tankers are generally equipped with a large number of longitudinal and transverse bulkheads, mainly grooved bulkheads, and oil tanks are divided into several tanks by a number of longitudinal and transverse bulkheads. According to the principle of segmented hull construction, in order to facilitate segmental manufacturing, the existing assembly method of the general section of the corrugated bulkhead is as follows: hoist the transverse corrugated bulkhead to the dock or slipway, and then hoist the longitudinal corrugated bulkhead to the dock or both sides of the transverse corrugated bulkhead on the berth, the transverse corrugated bulkhead and the longitudinal corrugated bulkhead form a corrugated bulkhead segment; the deck segment is hoisted to the corrugated bul...

AI Technical Summary

Problems solved by technology

[0004] 1. The crane needs to reciprocate the horizontal tank wall segments, longitudinal tank wall segments and deck segments to the dock or berth, which is not conducive to rapid loading work;

[0005] 2. The connection method between the trough bulkhead and the deck is angle welding, which is difficult to weld, resulting in poor welding quality;

[0006] 3. The trough-shaped bulkhead section, the deck section and the dock or slipway body form a closed chamber, and construction personnel work in the chamber, resulting in poor operating safety;

[0007] 4. A lot of hoisting and welding work is carried out on the berth or dock, which is inconvenient and prolongs the construction period of the berth or dock
