Definitions
- the present invention relates to a temporary surface coating in particular to allow or facilitate the movement of vehicles on sandy or marshy soils and more precisely a flexible coating deployable like a carpet.
- the surface coating according to the invention is suitable for all types of surface with insufficient coherence or all unstable soils, including in particular sandy, marshy or muddy soils, which do not have sufficient coherence when passing, for example, gear. two-wheel drive.
- the present invention aims precisely to provide a surface coating suitable for the circulation of vehicles on sandy or marshy ground.
- the subject of the invention is a temporary surface coating, in particular for the circulation of vehicles on sandy or marshy soil, 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, the 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 zone of simple and tight weave followed by a zone floats, the alternation of the various aforementioned zones causing tightening of the weft threads creating a significant relief of the fabric thus produced.
- Such a structure rolls like a carpet is relatively light and flexible so as to easily fit the profile of the ground to be covered, allows easy rolling of machines, without penetration of the structure into the sand and allows passage even in steep slopes thanks to the projections made in the woven structure and which are in the form of transverse ribs on which the tires of the machines easily adhere.
- FIG. 1 shows an armor of a woven covering structure according to the invention
- FIG. 2 is a diagram showing a woven structure according to the weave of Figure 1, the warp son being in the plane of the figure
- Figure 3 is a partial schematic perspective view of a structure woven in accordance with Figure 2
- Figure 4 shows the weave of Figure 2 reduced to the weft threads and warp thread No. 1;
- Figures 5 to 13 are homologous figures of Figure 4 but with the warp threads No. 2 to No. 10 respectively;
- FIG. 14 to 16 show another armor of a structure according to the invention.
- FIG. 1 there is shown a preferred weave of a woven structure according to the invention.
- This armor conventionally represented, comprises ten warp threads, numbered 1 to 10, opposite ten vertical columns and twenty six weft threads, numbered 1 to
- FIG. 2 represents a piece of woven structure corresponding to the weave of FIG. 1, the weft threads marked 1 to 26 being seen at the end and represented by small circles, while the warp threads are arranged in the plane of the figure and identified by numbers 1 to 10 in small rectangles.
- the woven structure is produced from a single layer of warp threads and a single layer of weft threads.
- the weft threads are monofilaments in order to provide the woven structure with the necessary rigidity and are preferably threads with a diameter of between 50 and 200 hundredths of a millimeter, of a suitable material such as plastic and in particular a material chosen from the group comprising: polyesters, polyamides, polypropylenes and polyethylenes.
- the warp threads may or may not be monofilaments, of the same material as the weft threads or not and of a diameter generally less than that of the weft threads.
- the weft and warp threads have a diameter of 80 hundredths of a millimeter and 50 respectively.
- each warp thread intersects with the weft threads at half of the intersections rows and columns of the weave, the warp wire being left in the remaining intersections.
- the warp thread N ° 1 is taken thirteen times and left thirteen times.
- the warp thread N ° 1 intersects with the weft threads (numbered 1 to 26) in a simple and tight weave of canvas type, in two areas called A preceded and followed each by a zone called B where the warp thread N °
- Each zone A or B covers several consecutive weft threads.
- FIG. 5 to 13 illustrate the other warp threads
- zones A and B we can see in these figures 4 to 13 that, for each warp thread, there is an alternating succession of zones A (weave type canvas) and B (warp threads left) and that the number of zones A and zones B may vary from one warp thread to another.
- This fabric thus has on its two faces an embossed structure with ribs (S1, S2, C1, C2) transverse to the direction of movement of the machines and which ensure good attachment of the tires.
- the woven structure rolls and unrolls like a carpet and is therefore easy to set up and remove, the grammage being, for polyester threads of 80 hundredths of a mm (weft) and 50 hundredths (warp), of 725 grams per square meter, the structure having a thickness of the order of a centimeter.
- the structure has the appearance of a grid and, although flexible and deformable, is elastic and regains its shape after the passage of the wheels. It does not sink into the sand, on the other hand, during its removal, its sieve structure avoiding the retention of the sand which is thus not loaded.
- the structure is of course rot-proof and, moreover, leaves the ground substantially flat without any rut where it was deployed. Finally, it lets water pass completely, which prevents gullying.
- Many variations can be made to the type of armor in Figure 1.
- the warp threads can have zones A and B different in number of weft threads concerned and in arrangement in the weave design.
- all the warp threads or a certain number can have the same zone profile A, B.
- Figures 14 and 15 illustrate two other armors which have a ratio (10/24) slightly different from that (10/26) of the armor of Figure 1 and in which there is no equality of taken and left for each warp thread.
- each warp yarn of the armor comprises as many takes as left.
- the warp threads have a diameter generally less than that of the weft threads.
- the diameter of the warp threads is only slightly smaller than that of the weft threads.
- the coating having a weave according to FIG. 1 has a thickness of the order of 10 millimeters, a grammage of approximately 725 grams per square meter and 1,000 warp threads per meter, with a diameter of 50 hundredths of a millimeter and 620 weft threads per meter, with a diameter of 80 hundredths of a millimeter.
