| 摘要 | 1314740 Dry docks NIPPON KOKAN KK 29 Dec 1970 [27 Dec 1969] 61408/70 Heading B7S Two basins 1 of a dry dock are connected by tunnels 5 so that equipment can be moved within the basins without the use of a crane for lifting it over the dividing wall 3. The tunnels can also be used to store equipment. The basins and tunnels have watertight gates 2 and 6. When one basin is to be emptied and the other is to be filled, the tunnels may be used to equalize the water levels in the basins before draining and flooding proper are commenced. Water gates may divide one or both basins into compartments to be used for the building of ship sections. In another arrangement, Figs. 3 and 4 (not shown), each basin has a sea gate at one end only. | ||||||
