The invention discloses a channel system hatch cover construction method. The method comprises the following steps that a jig frame is manufactured; plates are gradually spliced from the center of thejig frame to the broadside to form a hatch cover plate; framework lines are drawn on the hatch cover plate; transverse frameworks and longitudinal frameworks are vertically welded on the hatch coverplate according to the framework lines, and welding deformation is corrected after welding is completed; a reinforcing plate is fixed at one ends of the longitudinal frameworks; a plurality of hinge eye plates are installed on the reinforcing plate, and then, fixing holes in the hinge eye plates are bored to the required size; and the hatch cover plate is removed from the jig frame. By means of the method, the problem that the construction precision of the large-size hatch cover is difficult to control is solved, and the problem that the construction efficiency is low due to the fact that boring is conducted after the hatch cover is installed on a ship is solved.
本发明公开了一种通道系统舱口盖建造方法,包括以下步骤:制作胎架;从胎架中心向舷侧逐步拼板拼装成舱口盖板;在舱口盖板上划出构架线;按照所述构架线,在舱口盖板上垂直焊接横向构架和纵向构架,焊接完成后,对焊接变形进行矫正;在所述纵向构架的一端部固定加强板;在加强板上安装多个铰链眼板,然后将铰链眼板上的固定孔镗孔加工至要求尺寸;将舱口盖板从胎架上拆除。本发明不仅解决了大尺寸舱口盖建造施工精度控制难度大的问题,也解决了舱口盖上船安装后再进行镗孔加工而造成施工效率低的问题。
