Definitions
- the present invention relates to a mesh or lattice container structure for protection against erosion.
- the invention has been developed for the use of container structures, for example cages or gabions, in an underwater environment for the protection against erosion of watercourses, and more particularly of the bed and banks of rivers, canals and similar, essentially as an alternative to traditional rockfill protection.
- the invention can also be adopted for the protection of river bridge piers, and for the protection of rafts downstream of thresholds or dams and the like.
- Parallelepipedic structures made of a double-twisted hexagonal metal mesh have been used for a long time, as covers and as protective structures in order to prevent soil erosion.
- Said structures used for aquatic applications are preferable ent constituted by cages with multiple cells in wire mesh shared in compartments by diaphragms of the same kind and filled with stones, pebbles and the like.
- multi-cell gabions they are placed side by side on the bottom of the bed of the river without any ligature or connection between them, when the laying operation is carried out underwater. Consequently, these multi-cell gabions are likely either to be placed approximately taking into account the difficulties of laying underwater, or to move slightly at any time and thus offer sufficient space between them to allow the current to erode. the parts of the bottom that 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 of erosion between the elements.
- Another objective of the invention is to provide a product designed to meet this need while optimizing its implementation on the site, often carried out under difficult conditions.
- a final objective of the invention is to ensure a result guarantee for protection against erosion while offering a reliable and durable solution over time, with the greatest simplicity of use and manufacture while guaranteeing degrees resistance and stability to the entire protected area.
- This product includes a 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 extension skirt joined integrally to the base of the cage or the gabion is preferably, but not limited to, in a metallic mesh of double-twist hexagonal mesh, doubled on or under the face of a geotextile or a protective material preventing the escape of particles from the ground in the event of exposure to hydraulic stresses.
- the extension skirt is rigid enough to be laid flat and without any folds on the bottom, all being subsequently covered by the structure of the neighboring gabion to ensure effective protection of the bottom 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 an aquatic environment for the production of anti-erosive protections to be carried out under water.
- This solution is easy to implement, and has the advantage of dispensing with ligating and assembling the gabions together while at the same time ensuring good protection between the gabions.
- FIG. 1 is a perspective view of an embodiment of an improved multi-cell gabion according to the present invention
- FIG. 2 illustrates a typical use of the two improved gabions juxtaposed and in contact
- Figure 3 illustrates the two gabions of Figure 2 in the event of separation, due for example to a faulty implementation or to a movement of the protection during service.
- a container or envelope structure according to the present invention has been designated in its entirety by 10, for example a gabion or a grid or trellis cage.
- This gabion 10 comprises 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 nature and are lined on the underside or covered with a geotextile or a protective material 15 preventing the escape of particles from the ground in the event of exposure to the current.
- the gabion 10 is preferably divided into cells by intermediate walls or diaphragms 16.
- the base 12 and its overhang 14 are formed by a single rectangular sheet having a hexagonal mesh structure preferably formed by a double twist wire mesh coated with a zinc and aluminum alloy , known under the trade name of GALFAN ® , and plasticized for example with a coating of PVC or a similar material.
- the outer projection 14 forms a single piece with the base 12 of the gabion.
- All the side walls 11 and intermediate 16 are preferably made of double-twisted mesh, and are assembled at the base 12 of the gabion, if they must be, preferably in the factory.
- the gabion 10 at least partially by folding from a single mesh ply, constituting the base 12 with its projection 14 and two of the sides opposite to the projection 14.
- the two side walls 11 contiguous to the overhangs 14 are assembled in the factory by stapling or by a similar manufacturing method.
- the cover 13, independent of the structure of the base 12 and side walls 11 and intermediate 16, is preferably produced by a single mesh ply. It may, in the case of large rectilinear sections, be replaced by a mesh roll having the same mesh and the same characteristics as the mesh constituting the base and the walls of the gabion.
- the geotextile 15 is placed entirely under the overhangs 14 and partly overflowing under the base 12; this operation can preferably be carried out in the factory by mechanical stapling.
- the gabions or cages 10 are filled according to the rules of the art, so as to ensure a uniform filling and limit the voids as much as possible.
- Multiple-cell gabions can be shaped in different ways, thus making it possible to bend, overlap or juxtapose curves.
- the banks, embankments or river beds capable of being protected using gabions with overhangs according to the present invention are previously cleaned, reprofiled and leveled to be free from any depressions or asperities, branches, stumps or other. Where appropriate, reloads may be carried out in areas that are too hollow in order to respect the regularity of the ceilings.
- the gabions 10 are mounted, filled and closed ashore on a prefabrication area provided for this purpose.
- the gabions 10 are transported and handled to be installed in their final location. Particular care will also be taken to level the overhangs 14 on the ground without damaging the geotextile 15 on the underside.
- a nonwoven geotextile filter of the known type or any other process having the same function is interposed between the ground and the gabion 10. This geotextile is installed in the cage before filling, which is carried out with the materials defined above, followed by 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 of their implementation by suitable means, which must be designed in such a way that the handling of the gabions causes little or no deformation of the structure, and that each gabion is lifted in several points without risk of injury to the wires, or high work rate in the metal wires.
- the filled structure can for example be moved using a lifting beam or other known handling means clinging to a lifting device of the strap type or other taking up in a distributed manner the forces under load of the gabion.
- the gabions 10 are then placed and juxtaposed in an underwater environment 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 with the cage of the neighboring gabion, as illustrated in FIG. 2.
