The invention discloses a chemical tanker U-shaped block assembly and carrying precision control method. A U-shaped block comprises a deck subsection, a transverse bulkhead subsection and two longitudinal bulkhead subsections; and the end face of a block ring section is U-shaped. The control method comprises the following steps of: S1, preparing to fold and position the subsections in an inverse state; S2, performing deck positioning precision control; S3, performing positioning precision control of the transverse bulkhead; S4, performing the positioning precision control of the two longitudinal bulkhead subsections at the same time; S5, strengthening a block forming structure; S6, performing three-dimensional precision detection precision control on the block before welding; S7, performing welding process precision control; S8, performing three-dimensional precision detection precision control after block welding; and S9, turning over the block to be in a normal state through a crane,and then hoisting and transporting the block through the crane to be carried and folded. The method has the beneficial effects that the overall precision size of the U-shaped block is good, the problem of on-site segmented butt joint assembly deviation is avoided, and the construction quality of chemical ships is guaranteed.

    本发明公开了一种化学品船U型总段总组与搭载精度控制方法,U型总段包括一甲板分段、一横隔舱分段、两纵隔舱分段,总段环段端面呈现U字形状,所述控制方法包括如下步骤:s1准备将分段在反态状态下进行合拢定位;s2甲板定位精度控制;s3横隔舱定位精度控制;s4两个纵隔舱同时定位精度控制;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U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。
