Description
OR CONTAINER STRUCTURE FOR PROTECTION AGAINST EROSION OR CONTAINER STRUCTURE FOR PROTECTION AGAINST EROSION The present invention relates to a or container structure for protection against The invention has been developed for the use of container for cages or in an underwater environment for protection against the erosion of waterways and more particularly the bed and banks of the substantially as an alternative to traditional protection The invention can also be used to protect river bridge piers and to protect features which are downstream of barriers or barrages and the Parallelepipedal structures made from a grid of twisted hexagonal metal meshes have been used for some in covers and as protection structures in order to prevent soil The aforementioned structures used for aquatic applications are preferably constituted by cages having multiple cells in the form of a metal grid which are divided into compartments by diaphragms of the same nature and which are filled with pebbles and the Commonly known as they are positioned side by side on the bottom of the river bed without being bound or connected together when the positioning operation is carried out under these gabions are at risk either of being positioned in an approximate manner owing to the difficulties of positioning under water or of being slightly displaced at any time and thus providing sufficient space between them to allow the current to erode the portions of the bed which are no longer These gabions do not therefore provide a complete guarantee of The of the present invention is therefore to overcome the disadvantages of the prior art by providing an improved product which prevents those risks of erosion between the Another object of the invention is to provide a product which is designed to meet this requirement whilst optimising the application thereof in often carried out under difficult A final object of the invention is to ensure a successful guarantee of protection against erosion whilst providing a solution which is reliable and durable over time and which is as simple as possible to use and to produce whilst ensuring high levels of strength and stability for the whole of the protected These objects are achieved by means of a or container structure for protection against wherein the structure is to be filled with pebbles or another construction This product comprises a base or lateral walls or panels and an upper portion or is characterised in that the base has a projection or skirt on at least one According to a feature of the present the extension skirt which is fixedly joined to the base of the cage or the gabion is but in a in the form of a metal grid which has a twisted hexagonal mesh and which lined on or in the underside with a geotextile or a protective material which prevents particles of soil from being removed they are exposed to hydraulic this the extension skirt is sufficiently rigid to be positioned correctly in a flat manner and without being folded at the bottom whilst being subsequently covered by the structure of the adjacent gabion in order to ensure effective protection of the base of the river bed in the contact zone between the two gabions in this the product according to the present invention is completely appropriate and suitable for use in an aquatic environment for producing protection systems which are to be carried out under This solution is simple to use and has the a of dispensing with binding and assembling the gabions together whilst at the same ensuring good protection between the Further features and advantages will be better understood from a reading of the following description of one embodiment and with reference to the appended drawings which are given purely by way of example and in Figure 1 is a perspective view of one embodiment of an improved gabion according to the present Figure 2 illustrates a typical use of the two improved gabions which are juxtaposed and in Figure 3 illustrates the two gabions of Figure 2 having been moved for to incorrect application or a movement of the protection during Reference will be now be made to the Figures in which a container or housing structure according to the present for a gabion or a or like has been generally designated This gabion 10 comprises a parallelepipedal structure which is preferably produced from a metal grid and which has lateral walls or panels a base or bottom 12 and a cover The base 12 has a projection 14 on at least one side and preferably on least two adjacent The base 12 and the projection 14 thereof are of the same nature and are lined the underside or covered with a geotextile or a protective material 15 which prevents particles of soil from being removed when exposed to the The gabion 10 is preferably divided into cells by intermediate walls or diaphragms According to one embodiment of the gabion the base 12 and the projection 14 thereof are formed by a single rectangular sheet having a hexagonal mesh structure which is preferably formed by a mesh of metal wire coated with an alloy of zinc and known under the trade name and coated with plastics for with a coating of or a similar The outer projection 14 is integral with the base 12 of the When the projection 14 extends on at least two adjacent sides of the and projections are provided in accordance with the structural arrangements of the All the lateral walls 11 and intermediate walls 16 are preferably produced in the form of wisted grids and are preferably assembled with the base 12 of the if they need to in the The gabion 10 can also be produced at least partially by being folded from a single grid sheet which constitutes the base 12 with the projection 14 thereof and two of the sides opposite the projection In this the two lateral walls 11 which are adjacent to the projection 14 are assembled in the factory by means of clamping or a similar production The cover which is independent from the structure of the base 12 and the lateral walls 11 and intermediate walls is preferably produced from a single grid It in the case of large rectilinear be replaced by a grid roll having the same mesh and the same properties as the grid which constitutes the base and the walls of the The geotextile 15 is positioned completely under the projections 14 and partially protruding under the base this operation can preferably be carried out in the factory by means of a clamping When in che gabions or cages 10 are filled according to the provisions of the art in order to ensure homogeneous filling and to minimise empty gabions can be shaped in different manners which thus allows curves to be produced by means of overlapping or The river slopes or beds which are intended to be protected with gabions having projections according to the present invention are reprofiled and levelled beforehand in order to be free from any depressions or stumps r the If it is possible to carry out localised filling in excessively hollow zones in order to ensure the regularity of the For work when water is the gabions 10 are filled and closed with earth in a pref brication region provided for this In a second the gabions 10 are transported and handled in order to be installed at their definitive Particular care is also taken to level off the projections 14 relative to the ground without the underside of the geotextile 15 being In order to prevent lifting and mud from being carried under the gabions 10 owing to residual hydraulic a geotextile filter of known type is interposed between the ground and the gabion or any other method having the This geotextile is installed in the cage before it is which is carried out with the materials previously followed by a superficial manual finishing arrangemen After the filling of the gabions 10 has been the free edges of the cover are adjusted and positioned above the edges of the corresponding In order to fix the first the edges of perimeters are clamped particular care being taken at the and subsequently the The gabions 10 are then transported to their place of use by suitable means which must be designed in such a manner that the handling of the gabions does not bring about or very deformations of the structure and that each gabion is raised at several points without any risk of damage to the wires or high stress rates in the metal The filled structure for be displaced by means of lifting beam or other known handling means which is hooked to a lifting device of the strap type or the like which absorbs the loading efforts of the gabion in a distributed The gabions 10 are then positioned and juxtaposed in the underwater environment so that the spaces between each gabion 10 are limited to the greatest possible extent at their definitive must be ensured that the projection 14 of each gabion 10 is covered by the cage of the as illustrated in Figure When a current tends to separate two adjacent gabions the exposed zone 17 between them Figure remains protected by the projection while preventing the erosion of the river bed below the geotextiles In this the protection between the gabions is ensured by the pro It will be appreciated that various modifications and variants can be carried out by the person skilled in the art to the device which has been described above purely by way of example without departing the scope of the insufficientOCRQuality
