Abstract
The barrier proposed by the invention consists of gate elements or components which move on inclined planes, characterized by the fact that in the rest position on the edge of the waterway, preferably on the shore, the gate elements or components can be inserted inside one another in telescope fashion. With suitable lengths of the foundations forming the inclined planes, the gate elements which can be moved in tracks independently of one another can be removed completely from the water and pushed together above the average high water level. The cross section of the gate elements has a triangular shape, whereby the ocean-side supports the dam wall and the inland side primarily absorbs the bracing forces.
Claims20
A barrier apparatus for retaining water in a body of water, such as for damming a tidal waterway in the event of a storm tide, the body of water having a bottom, a first shore and a second shore, said barrier apparatus comprising:
- a plurality of barrier elements for retaining water;
- at least some of said barrier elements being adjacent to one another;
- and
- said plurality of barrier elements having means for telescopically retracting at least some of said barrier elements into adjacent barrier elements and for telescopically extending at least some of said barrier elements such that said barrier apparatus extends towards the first shore during the extending of at least some of said barrier elements.
A method of utilizing a barrier apparatus for retaining water in a body of water, such as for damming a tidal waterway in the event of a storm tide, the body of water having a bottom, a first shore and a second shore, the barrier apparatus comprising:
- a plurality of barrier elements for retaining water;
- at least some of the barrier elements being adjacent to one another;
- and
- the plurality of barrier elements having means for telescopically retracting at least some of the barrier elements into adjacent barrier elements and for telescopically extending at least some of the barrier elements such that the barrier apparatus extends towards the first shore during the extending of at least some of the barrier elements;
- and
- said method comprising the steps of:
- telescopically extending at least some of the barrier elements such that the barrier apparatus extends towards the first shore during said step of telescopically extending and retains water in the body of water;
- and
- telescopically retracting at least some of said barrier elements into adjacent barrier elements.
