Abstract

PURPOSE:To make easier operation for the under-water portion of a structure by providing an under-water maintenance trunk consisting of a bottom trunk and a rising trunk on the bottom of the structure in a pressingly attachable and movable manner along the longitudinal direction of the structure. CONSTITUTION:Under the condition that a rising trunk 11 is separated from a floating dock 1, the rising trunk 11 is combined to a bottom trunk 3 by a stay 16, an under-water maintenance trunk 2 is settled by charging water into the opening of the rising trunk 11, and the bottom trunk 3 is also separated from the dock 1. Then, the maintenance trunk 2 is put on a rail 15 through a roller 14 and moved to a given place. The maintenance trunk 2 is lifted up by a crane, etc., and the rising trunk 11 is pressed on the side of the dock 1 while sliding by stays 17 and 18 in contact with the bottom trunk 3 and the dock 1's bottom in a pressed manner. Then, water in the maintenance trunk 2 is discharged and work is performed.
