The invention discloses a construction method of a liquid cargo tank of an asphalt ship. The method comprises the steps that a tank body of a finished liquid cargo tank is designed and modeled through a ship product design system SPD, the tank body is annularly segmented and divided in the ship width direction, segmentation seams are marked, and the tank body is divided into a bow ring section, a midship ring section and a stern ring section; according to the positions and structural forms of the ring sections in the tank body, the ring sections are decomposed, the section numbers are compiled, the construction process is designed, the construction process comprises a small assembly stage, a middle assembly stage and a large assembly stage, and after the small assembly, the middle assembly and the large assembly are completed, the ring sections are hoisted to a total assembly platform to be folded into the whole liquid cargo tank. The welding and hoisting time in the total assembling and closing stages is short, the occupied construction site is small, and part of procedures are moved forwards.
本发明公开了一种沥青船液货罐的建造方法。该方法包括将成品液货罐的罐体通过船舶产品设计系统SPD进行设计建模,以船宽方向对罐体进行环状分段划分并标注分段缝,将罐体划分为艏环段、舯环段以及艉环段,根据各环段位于罐体的位置、结构形式对各环段进行分解、编制分段号并设计建造流程,建造流程包括小组立阶段、中组立阶段和大组立阶段,完成小组立、中组立以及大组立后吊运至总组平台合拢成液货罐整体。本发明总组及合拢阶段的焊接及吊运时间少、施工场地占用少,实现部分工序前移。
