The invention discloses a container ship double-layer bottom segmentation dividing method, a container ship comprises a double-layer bottom ballast tank and a transverse bulkhead, and the container ship double-layer bottom segmentation dividing method comprises the following steps that firstly, the transverse bulkhead is divided into an upper structure and a lower opening platform structure; secondly, the upper structure is independently built, and the lower opening platform structure and the double-bottom ballast tank are built together and welded; and thirdly, the upper structure and the lower opening platform structure are carried and installed. According to the method, the transverse bulkhead is divided in sections, so that the precision control requirement and the carrying and mounting difficulty during carrying of the transverse bulkhead are effectively reduced, and the use amount of transverse bulkhead supporting tools in the dock stage is reduced; and meanwhile, the segmentation difficulty coefficient and the segmentation tire position period of the double-layer bottom are reduced, the damage of the transverse bulkhead to paint of the double-layer bottom ballast tank is avoided, and the labor cost, the coating cost and the structural cost during carrying are saved.

    本发明公开了一种集装箱船双层底分段划分方法,集装箱船包括双层底压载舱和横舱壁,一种集装箱船双层底分段划分方法包括以下步骤:第一步,将所述横舱壁划分为上部结构和下口平台结构两个结构部分;第二步,将所述上部结构单独建造,所述下口平台结构与所述双层底压载舱一起建造,并进行焊接;第三步,将所述上部结构与所述下口平台结构搭载安装。本发明通过将所述横舱壁分段划分,从而有效降低了所述横舱壁搭载时的精度控制要求和搭载安装难度,减少了船坞阶段横舱壁支撑工装的使用量;同时降低了双层底的分段难度系数和分段胎位周期,避免了横舱壁对双层底压载舱的油漆造成破坏,节省了搭载时的人工成本、涂装成本和结构成本。
