The invention discloses a container ship hatch cover positioning pin advanced installation precision control method, which comprises the following steps of: drawing a hatch circumference datum line at the periphery of a hatch, and arranging manufactured hatch covers to simulate the real installation state of the whole group of hatch covers on a ship, so as to measure the offset of the hole center of a positioning pin hole of each hatch cover; and then the mounting position of the positioning pin is determined on the hatch coaming according to the datum line of the hatch coaming and the offset of the hole center of the positioning pin hole in the hatch cover, so that the mounting of the positioning pin can be carried out in advance to a dock stage, the mounting and positioning precision of the positioning pin is improved, and the wharf construction period is effectively shortened. Meanwhile, the use frequency and the use time of the crane in the subsequent construction process are also reduced, and the integrity of a ship body building intermediate product is effectively improved.

    本发明公开了一种集装箱船舱盖定位销先行安装精度控制方法,本发明通过在舱口四周画出舱围基准线,将制作好的舱盖进行排装以模拟出整组舱盖在船上的真实安装状态,从而测量得到每个舱盖的定位销孔孔心的偏移量,再根据舱围基准线和舱盖上定位销孔孔心的偏移量在舱口围上确定出定位销安装位置,从而可将定位销的安装提前至船坞阶段进行,不仅提高了定位销的安装定位精度,还有效缩短了码头建造周期。同时也减少了后续施工过程中吊车的使用频率和使用时间,有效地提高了船体建造中间产品的完整性。
