Definitions
- the present invention relates to a structure of mesh or protective container for protection against erosion.
- the invention was developed for the use of container structures, for example cages or gabions, in an underwater environment for protection against erosion of watercourses, and more particularly of the bed and banks of rivers, canals and the like, essentially as an alternative to traditional armourstone protections.
- the invention can also be adopted for the protection of batteries river bridge, and for the protection of rafts downstream sills or dams and the like.
- Structures have been used for a long time rectangular boxes made of a wire mesh metal hexagonal double twisted, in covers and as protective structures to prevent soil erosion.
- the said structures used for aquatic applications are preferably formed by multi-cell wire mesh cages metal divided into compartments by diaphragms of the same kind and filled with stones, pebbles and similar.
- Commonly known as cell gabions multiple they are placed side by side on the bottom of the bed of the river without any ligature or bond between them, when the laying operation is carried out underwater. Through therefore these multi-cell gabions risk either to be asked approximately given the difficulties of laying underwater, that is to move slightly at all moment and thus provide sufficient space between them to allow the current to erode the bottom parts which are no longer protected. These gabions therefore do not offer a total guarantee of anti-erosion protection.
- the objective of the present invention is therefore to solve the drawbacks of the known technique, by providing an improved product preventing said risks between the elements.
- Another objective of the invention is to provide a product designed to meet to this need while optimizing its implementation on the site, often carried out under conditions difficult.
- a final objective of the invention is ensure a result guarantee for protection against erosion while offering a reliable and durable over time, with the greatest simplicity of use and manufacture while guaranteeing high degrees of resistance and stability to the whole of the protected area.
- This product includes base or bottom, side walls or panels and a top or cover. It is characterized in that the base has an overhang or skirt on at least one side.
- the skirt extension joined solidly to the base of the cage or gabion is preferably, but not limited to, in wire mesh in double-twist hexagonal mesh, lined on or under a geotextile or a protective material preventing the escape of particles from the soil in the event of exposure to hydraulic stress.
- the extension skirt is sufficiently rigid to be laid flat and without creases on the bottom, everything being subsequently covered by the structure of the neighboring gabion to provide effective bottom protection of the river bed in the contact area between the two gabions.
- the product according to the present invention is thus perfectly indicated and suitable for use in aquatic environment for the realization of anti-erosive protections to be done underwater.
- This solution is easy to implement, and has the advantage of dispensing with tie and assemble the gabions together while at the same time ensuring good protection between gabions.
- This gabion 10 includes a parallelepiped structure, preferably made of wire mesh, with walls or side panels 11, a base or bottom 12 and a cover 13.
- the base 12 has an overhang 14 on at least one side, and preferably at least two adjacent sides.
- the base 12 and its overhang 14 are of the same type and are lined on the underside or covered with a geotextile or protective material 15 preventing particle leakage from the ground if exposed to current.
- the gabion 10 is preferably divided into cells by walls intermediate or diaphragms 16.
- the base 12 and its overhang 14 are formed by a single sheet rectangular with a hexagonal mesh structure preferably formed by a double twist mesh in metal wire coated with an alloy of zinc and aluminum, known under the trade name of GALFAN®, and plasticized by example with PVC coating or material similar.
- the outer overhang 14 forms a single piece with the base 12 of the gabion. When it overflows 14 extends over at least two adjacent sides of the gabion, it there are “right” overhangs and “left” overhangs in according to the construction provisions of the site. All the side walls 11 and intermediate 16 are preferably made of double twist mesh, and are assembled at the base 12 of the gabion, if they must be, preferably in the factory.
- the cover 13, independent of the structure of the base 12 and side walls 11 and intermediate 16, is preferably made by a single layer of fence. It may, in the case of large sections straight, to be replaced by a roll of wire mesh having the same mesh and the same characteristics as the mesh constituting the base and the walls of the gabion.
- Geotextile 15 is placed entirely under the overflows 14 and partly overflowing under the base 12; this operation can be carried out preferably in factory by mechanical stapling.
- the gabions or cages 10 are met according to the rules of the art, so as to ensure homogeneous filling and minimize empty.
- Multiple cell gabions can be shaped in different ways, allowing realize by folding, overlapping or juxtaposition of curves.
- Banks, embankments or river beds likely to be protected with gabions with overhangs according to the present invention are previously cleaned, reprofiled and delighted to be free from all depressions or roughness, branches, stumps or others. We will be able to if necessary, reload localized in areas that are too hollow in order to respect the regularity of the ceilings.
- gabions 10 For work in the presence of water, gabions 10 are assembled, filled and closed ashore on an area of prefabrication provided for this purpose. In a second step, gabions 10 are transported and handled for be installed in their final location. We will bring also a particular care in the leveling of overflows 14 to the ground without damaging the geotextile 15 in under face. In order to avoid kidnapping and training fines under the gabions 10 due to stresses residual hydraulic, between the ground and the gabion 10 a known nonwoven geotextile filter or any other process having the same function. This geotextile is installed in the cage before filling, which is made with the materials defined above, followed of a manual surface finishing arrangement.
- the free edges of the cover are adjusted and positioned above the edges of the corresponding gabions.
- the gabions 10 are then transported to the place their implementation by adequate means, which must be designed in such a way that the handling of gabions causes little or no structural deformation, and that each gabion is lifted at several points without risk of injury to wires, or work rate high in metal wires.
- the filled structure could for example be moved using a lifting beam or other known handling means clinging to a lifting device such as straps or other distributed way the loads in charge of the gabion.
- the gabions 10 are then placed and juxtaposed underwater so that the spaces between each gabion 10 are best limited in their final location. We must make sure to cover the overhang 14 of each gabion 10 through the gabion cage neighbor, as shown in Figure 2.
