Abstract
A dry dock for building and/or dismantling a naval structure includes a substantially horizontal floor located below a predetermined top level, dock side walls extending from the floor to the top level, and a closable access provided in a side wall for moving a naval structure into the dry dock. At least two of the side walls are partly slanted and include a water-impervious layer. The invention also provides a method for constructing the dry dock.
Claims21
A dry dock for building and/or dismantling a naval structure, comprising:
- a substantially horizontal floor that is located below a predetermined top level,
- dock side walls extending from the floor to the top level, and
- a closable access provided in a said dock side wall for moving a naval structure into the dock, said closable access being in mechanical communication with said dock side wall in a continuously water-tight manner up to a level at or close to said top level,
- wherein each of at least two of the dock side walls is an at least partly slanted side wall, comprising a slope and a water-impervious layer which comprises a water-impervious foil and is configured to act as a ground water barrier, and comprising a first stabilizing layer extending below the water-impervious layer and a second stabilizing layer extending above the water-impervious layer.
A method for constructing a dry dock comprising in no particular order the steps of:
- providing a substantially horizontal floor;
- providing dock side walls;
- and
- providing a closable access in a said dock side wall, said closable access being in mechanical communication with said dock side wall in a continuously water-tight manner up to a level at or close to a predetermined top level;
- wherein each of at least two of the dock side walls is constructed to have an at least partly slanted side wall along a dock vessel receiving area, and said at least partly slanted side wall is provided with a water-impervious layer which comprises a water-impervious foil and is configured to act as a ground water barrier, and is provided with a first stabilizing layer extending below the water-impervious layer and a second stabilizing layer extending above the water-impervious layer.
