The invention relates to a dome structure of an independent low-temperature liquid cargo tank and a mounting method thereof, a dome coaming penetrates through a hull deck, the lower end of the dome coaming is connected with the liquid cargo tank, and a dome top plate covers the upper end of the dome coaming; the hull deck is provided with an opening corresponding to the dome coaming, and the aperture of the opening is larger than the size of the dome top plate; a sealing connecting component is connected between the dome top plate and the ship body deck, and the sealing connecting component is a flexible connecting piece; the sealing connecting components are arranged along the outer circle of the dome coaming; a manhole and a through hole are formed in the dome top plate. During installation, the internal supporting plate and the dome coaming are installed on the lower end face of the dome top plate and then welded to a cargo tank deck, an opening is formed in a ship body deck to install the external supporting plate, the dome coaming penetrates through the opening of the ship body deck, and the sealing connecting component and the water blocking cover plate are installed between the internal supporting plate and the external supporting plate. Relative deformation and displacement of the structure are released through flexible connection, construction is convenient, fire operation after carrying is avoided, and potential safety hazards are reduced.
本发明涉及一种独立型低温液货舱的穹顶结构及其安装方法,穹顶围板穿过船体甲板,穹顶围板的下端连接液货舱,穹顶顶板盖在穹顶围板上端;船体甲板对应穹顶围板设有开孔,开孔口径大于穹顶顶板的尺寸;穹顶顶板和船体甲板之间连接密性连接构件,密性连接构件为柔性连接件;密性连接构件沿穹顶围板外部一圈设置;穹顶顶板上设有人孔和贯穿孔。安装时,在穹顶顶板的下端面安装内部支撑板和穹顶围板,然后焊接到液货舱甲板上,在船体甲板上开设开孔安装外部支撑板,穹顶围板穿过船体甲板的开孔,在内部支撑板和外部支撑板之间安装密性连接构件,安装拦水盖板。本发明通过柔性连接释放结构相对变形和位移,方便建造,避免搭载后动火,减少安全隐患。
