Definitions

• the present invention relates to an improvement to the type of temporary surface coating, in particular for the circulation of vehicles on sandy, muddy or marshy ground, which is the subject of French patent No. 2 71 8 1 58 in the name of the Applicant.
• the above patent describes a coating characterized in that it consists of a woven structure formed from weft threads of the monofilament type arranged in a single layer and warp threads also arranged in a single layer, the weave of the woven structure being such that each warp thread intersects with the following weft threads, preferably and very approximately, half of the intersections of the rows and columns of the weave, the warp thread being left in the intersections remaining, so, for each warp thread, to obtain at least one area of simple and tight weave followed by a float area, the alternation of the various aforementioned areas causing tightening of the weft threads creating a significant relief fabric thus produced.
• pockets capable of receiving flexible or rigid elements, or of being inflated using a pressurized fluid.
• Such a coating structure is necessarily weakened at the level of the pockets and its physical properties are very appreciably modified and altered due to the loss of the integrity of the structure woven at the locations of the pockets.
• the present invention specifically aims to overcome the drawbacks of the above coatings.
• the subject of the invention is a temporary surface coating, in particular for the circulation of vehicles on sandy, muddy or marshy soil, of the type with a woven structure formed of warp and weft threads, the armor of which is such that each warp thread intersects with the following weft threads, preferably and very approximately, half of the intersections of the rows and columns of the weave, the warp thread being left in the remaining intersections, so, for each warp thread, to obtain at least one simple and tight weave area followed by a float area, characterized in that a second auxiliary woven structure is superimposed and comprises a ply of warp threads and a ply of weft yarns, the connection between the two woven structures being carried out during a same simultaneous weaving operation with interweaving of the structures, so as to constitute between the two structures, from place to place ce, tubular pockets oriented along the warp threads or according to the weft threads, said pockets serving as a housing for receiving elements added for various purposes.
• Such bars in particular when they are inserted into pockets formed transversely to the covering, that is to say parallel to the weft threads, significantly improve the bearing capacity while strengthening the attachment of the surface in contact in particular with the vehicle tires circulating on such a coating.
• FIG. 1 is a very schematic and partial view of the edge of a complex according to the invention comprising two superimposed woven structures
• FIG. 2 is a perspective view of a coating according to the invention provided with transverse stiffening elements
• FIG. 1 there is shown diagrammatically at 1 the cross section of a woven structure forming a covering, of the type described in French patent No. 2 71 8 1 58.
• This coating has on its two faces an embossed structure with transverse ribs formed by projections S and recesses C, which give the coating its fastening properties of vehicle tires called to move on this coating.
• this woven structure 1 is associated, in superposition, a second woven structure symbolized at 2, consisting of a 4
• the pockets 3 are made from place to place, at regular intervals.
• the pockets 3 receive, at the time of weaving or later, an elongated stiffening element 4, such as a bar for example made of composite material a few tens of millimeters in diameter.
• the bars 4 for example of the glass fiber and polyester resin type and 25 mm in diameter, are held captive in the pockets 3 between the two woven structures 1, 2 and give the covering an increased bearing capacity while reinforcing the salient character of the zones S where said bars are inserted 4.
• the material, the diameter and the length of the bars 4 may vary.
• FIG. 2 represents a coating according to the invention with transverse stiffening elements 4.
• FIG. 3 represents a covering according to the invention with stiffening elements 4 ′ inserted in pockets 3 ′ produced along the longitudinal axis of the covering 1 ′, that is to say the warp threads of the woven structure of said covering.
• These pockets 3 ' are also produced in the manner mentioned above, by conventional means, during the weaving and assembly of the two woven structures (V, 2'). They can receive stiffening elements 4 ′, in particular flexible tubes, for example 70 mm in diameter, which can be inflated using a pressurized fluid, such as water, from a appropriate source 5.
• stiffening elements 4 ′ in particular flexible tubes, for example 70 mm in diameter, which can be inflated using a pressurized fluid, such as water, from a appropriate source 5.
• the inflating with water of the tubes 4 ' also allows the deployment of the complex 1', 2 'over a body of water, to allow the crossing of a watercourse for example, the whole immersing without problem and coming to land on the bottom.
• the coating ( 1, 1 ') can be fitted with devices or means placed in pockets (3, 3') and ensuring the detection of cavities or mines and possibly their destruction.
• Any other measuring device can be placed in said pockets.
• These same pockets can be provided with self-destruction means rendering the coating unusable after use.
