Abstract
The present invention relates to a secondary positioning method for the floating states of a half ship in a dock. In the secondary positioning method, a limit device is arranged between a hull of the half ship and the dock before water enters the dock. When floating, the half ship is limited to float in an original position and the position is not changed after the half ship floats. After the water of the dock is discharged, the half ship is limited to restore to the original position by the limit device. Therefore, the half ship floats and restores in the original position. The method of the present invention is used for secondarily positioning the floating states of the half ship in the dock, and has the advantages of simple operation and reliable performance. Time for rearranging dock blocks is saved, and shipbuilding progress is accelerated.
Description
Technical field
