Background In the corner box installation of the corner region of the transverse ring region of the liquid cargo tank of the NO.96 LNG ship, the corner boxes of 7, 8 and 9 are required to be plugged in the same gap between Yan Waguan and the bulkhead, and the distance between Yan Waguan and the bulkhead has strict technological requirements. In the process of installing the corner boxes 7, 8 and 9, the respective installation precision is usually adjusted by violent modes such as knocking, but as each transverse edge is as long as a few meters or even tens of meters, yan Waguan can be deformed to influence the quality precision when the corner box is knocked, and meanwhile, safety accidents can also occur. When the No. 9 corner box is installed, the distance between the front and rear No. 9 corner boxes is controlled through experience, and the installation accuracy and the installation quality of the No. 9 corner box cannot be guaranteed. And because transverse ring Yan Waguan is short and several meters long and tens meters long, the stress generated by the huge dead weight pulls and causes slight deformation after a long time, and after the three corner boxes of 7, 8 and 9 are installed, the distance between Yan Waguan and the bulkhead can be increased, and if the knocking force is not controlled in place when being regulated by knocking Yan Waguan, the quality of invar pipes can be influenced.
