The invention provides a precision control method for construction of a ring section of a movable deck of a roll-on-roll-off ship. The precision control method comprises the steps that S1, a construction positioning reference of the ring section is established, and a jig frame is installed; s2, the stand columns are positioned, and a first-layer movable deck is hoisted; s3, hoisting a second layer of fixed deck; s4, a broadside supporting seat is installed, and broadside segments are positioned; s5, a second layer of stand columns is positioned, and a third layer of movable deck is hoisted; s6, a fourth layer of fixed deck is hoisted; s7, the annular block with the four layers of decks is assembled; and S8, the assembled annular block is hoisted to the main hull. According to the technical scheme, a unified reference is established, under the condition that the structural strength of the movable deck is guaranteed, a well type construction method is changed into an annular block construction method, the movable deck supporting base is installed and moved forwards, the construction period of a main ship body on a slipway is greatly shortened, and the construction efficiency is improved. And the ship production and construction efficiency and the ship body construction precision are improved.

    本申请提供了一种滚装船活动甲板环段建造的精度控制方法,包括:S1:建立环形总段的建造定位基准并安装胎架;S2:定位立柱,并吊装第一层活动甲板;S3:吊装第二层固定甲板;S4:安装舷侧支撑座并定位舷侧分段;S5:定位第二层立柱,并吊装第三层活动甲板;S6:吊装第四层固定甲板;S7:装配上述具有四层甲板的环形总段;S8:将装配完成的环形总段吊装至主船体。本申请技术方案通过建立统一基准,在保证活动甲板的结构强度的情况下将活动甲板区域相关分段由井式建造法变为环形总段建造方式,并将活动甲板支撑座安装前移,大大减少了主船体在船台的建造周期,提高了船舶生产建造效率以及船体的建造精度。
