The invention discloses a precision control method for assembling and carrying a P-type block on chemical ship, a P-type block comprises a broadside segment, a groove-type compartment segment and a deck segment, the end face of a ring segment of the block is in a P shape, and the control method comprises the following steps: S1, preparing the segments to be folded and positioned in a lateral state; S2, controlling the positioning precision of the broadside segment; S3, carrying out precision control of the groove-type compartment segment; S4, carrying out deck segment positioning precision control; S5, reinforcing the block forming structure; S6, performing three-dimensional precision detection and precision control on the block before welding; S7, performing welding process precision control; S8, performing post-welding three-dimensional precision detection and precision control on the block; and S9, turning over the block into a normal state through a crane, and hoisting and transporting through the crane for carrying and folding. The method has the beneficial effects that the overall precision size of the P-type block is good, the problem of on-site segmented butt joint assembly deviation is avoided, and the construction quality of the chemical ship is guaranteed.

    本发明公开了一种化学品船P型总段总组与搭载精度控制方法,P型总段包括舷侧分段、槽型隔舱分段和甲板分段,总段环段端面呈现P字形状,所述控制方法包括如下步骤:s1准备将分段在侧态状态下进行合拢定位;s2舷侧分段定位精度控制;s3槽型隔舱分段定位精度控制;s4甲板分段定位精度控制;s5对总段成型结构加强;s6总段焊前三维精度检测精度控制;s7焊接过程精度控制;s8总段焊后三维精度检测精度控制;s9通过吊车将总段翻身为正态状态,再通过吊车进行吊装运输进行搭载合拢。本发明的有益效果为实现P型总段整体精度尺寸良好,避免现场的分段对接装配偏差问题,保证化学品船舶的建造质量。
