Definitions
- Shore fortifications, surf damping devices, breakwaters, retaining walls, groynes or the like are known, as are prefabricated elements for the production of these or similar structures.
- the main purpose of these known structures is to achieve erosion in the coastal area, especially on beaches, dunes, etc.
- Sands and other deposits for land reclamation sometimes occur to a very limited extent, but such structures are unsuitable for land reclamation.
- the drifting of islands cannot be prevented, so that the best possible protection of the existing shores is always in the foreground.
- sinkers Because of the rapid flow caused by the body shape, such sinkers are not suitable for targeted sanding and sanding, although occasionally small deposits can be found behind such sinkers.
- the known sinkers are also not applicable to beaches and other economically used coastal areas. They therefore do not affect the idea of the invention.
- the invention is based on the object, by means of a device in the coastal area, a targeted deposition, i.e. above all to achieve a shipping.
- the device according to the invention is arranged in the coastal area near the water surface, so that the water flowing against the coast flows over the artificial reef. It has been found that, depending on the slope and nature of the bank and the location of the artificial reef, deposits occur both in front of and behind the reef. These deposits occur in such large quantities that significant land reclamation takes place.
- the surfaces of the artificial reef sloping from the upper profile edge are formed keel-shaped and that the throat on the front facing the open water goes down into a contour of convex curvature, to which a profile edge forming a support foot connects.
- the device according to the invention is therefore particularly suitable for protecting beaches and dunes, but in particular for land reclamation in these areas.
- the desired effect is more pronounced in storms or storm surges.
- the shape and design of the artificial reef even allow it to be arranged in the area of bathing beaches without there being any danger to beach visitors.
- the device does not pose any danger to offshore shipping anyway. As a precaution, however, receiving openings for priggen and other shipping signs can be provided on the upper edge of the device.
- an artificial reef To form an artificial reef, several structures 1 are placed in rows next to one another on the sea floor below the water surface 2. For safe positioning, a deposit on a base 4 made of a steel mesh, a wire mesh or another suitable material can be provided in adaptation to the base 3.
- the structures to form the artificial reef can be deposited plane-parallel on the seabed 3, as shown on the left in FIG. 1, or with a certain inclination against the flow direction 5 of the water against the coast.
- the part joints 6 To connect the structures 1 to one another, it is recommended that the part joints 6 be offset, as can be seen from the plan view in FIG. 2, so that shoulder projections prevent the structures 1 from being displaced relative to one another transversely to the longitudinal direction of the artificial reef.
- a straight section 11 can be provided at the transition of the throat 9 into the counter-curvature 10, as is indicated in FIG. 1.
- the most effective curvatures for the throat 9 and the counter-curvature 10 and for the formation of the section 11 can advantageously be determined empirically in each individual case in adaptation to the flow conditions and the local installation conditions.
- FIGS. 5 and 6 schematically show further forms of embodiment for achieving the cavity 13 under the component 1 and for forming the support feet 12 which cause this cavity.
- FIG. 6 shows a cross-sectional profile which is particularly suitable if a weight-saving design is to be achieved. Reinforcements within the component 1 can ensure sufficient rigidity.
- the components are advantageously produced from a suitable concrete mixture which is suitable for arrangement under water. From the drawing examples in connection with the description it follows that the arc shapes of the cross-sectional profile shown also have other degrees of curvature up to slightly curved to stretched forward, especially in partial areas, as has already been mentioned in the introduction.
- mat underlays e.g. Fills or debris with rubble, concrete, or solid foundations.
