FR2850685A1 - Reinforcing or filtering component e.g. for dyke or embankment comprises wire cage filled with side walls from used motor vehicle tires - Google Patents

Abstract

The reinforcing/filtering component consists of a parallelepiped cage (1) of metal wire mesh filled with side walls (2) cut from used motor vehicle tires, either in a random pile or in stacks (3) of the same height or lower than the depth of the cage and bound together. The reinforcing/filtering component consists of a parallelepiped cage (1) of metal wire mesh filled with side walls (2) cut from used motor vehicle tires, either in a random pile or in stacks (3) of the same height or lower than the depth of the cage and bound together. One or more surfaces of the cage, and especially its base, has a lining of a geotextile material, and it can have transverse inner partitions. It is made in the form of an open-topped basket and fitted with a cover once it has been filled with the used tire side walls. A barrier for trapping oil at sea can be made from a series of cages with inflated rolls on either side for buoyancy.

Description

The present invention relates to reinforcing elements or

  sidewall filtration of used tires, as well as applications

using these elements.

  It relates generally to the field of building and public works and is in particular intended for the reinforcement of dikes, banks, embankments, roads in sandy areas and the like, but allows many other applications such as earthquake-resistant mattresses or traps fuel oil at sea.

  Tires which have become unusable represent a considerable volume of non-biodegradable material to be eliminated.

  Several means are currently used to achieve this. The used elements are generally reduced to pieces and used as fuel in specially fitted boilers.

  International patent application N0 FR 2 776 226 PCT - FR 99/00 587 filed by the author of the present application describes a machine intended to reduce used tires into pellets and consisting of an assembly 20 formed of a bead breaker and a press with multiple punches in which a feeding system makes pass the tire previously stripped of its heels by the bead breaker and opened thanks to a transverse cut to be able to lay it out flat.

  This technique makes it possible to recover used tires in order to improve the characteristics of certain construction and coating materials.

  The object of the present invention is to make possible new applications using used tires, in particular in the field of public works.

  It is characterized by wire cages containing stacks of sidewalls of reformed tires organized in stacks arranged side by side.

  In the appended drawings, given by way of nonlimiting examples of embodiments in accordance with the present application: FIG. 1 represents in perspective a trellis cage without cover filled with sidewalls of tires, FIG. 2 shows, on another scale, the cage empty and its cover, Figure 3 is a cross section of a reinforced dike by means of the device according to the invention and Figure 4 is a partial representation of a marine oil trap.

  The device, FIGS. 1 to 4, consists of parallelepiped cages 1 of wire mesh ("gabion cage") filled with sidewalls 2 of tires out of use for road vehicles.

  The sidewalls 2 may be piled up in bulk in the cages 1 but 15 will preferably be constituted in piles 3 of height equal to or less than that of the cages before being arranged in the latter in a contiguous manner, the flanks constituting each pile being maintained by links of known types.

  The parallelepiped cages 2 consist of a "basket" 4 and 20 of a cover 5 held on the latter after it has been filled by any suitable means.

  They may include transverse partitions 6 and may be lined with a geotextile sheath on all or part of their faces.

  These packaging, which will advantageously be produced in the factory and used as it is, can be used in many applications, and in particular for the infrastructure of sports grounds or traffic lanes, for the reinforcement of dikes 7 (FIG. 3), for the draining.

  An interesting application consists of an oil trap using the elements according to the invention (Figure 4) and intended to fight against oil spills.

  This device consists of several cages 1 full of sidewalls 2 of tires and placed side by side between two inflatable tubes, a front tube 8 provided with cables 9 allowing the assembly to be towed to bring it to work, and a rear flange 10 holding the cages 1 horizontal to facilitate their movement on the water.

  Once the trap has arrived in the area to be treated, the rear flange 10 is deflated. The sidewalls 2 of tires not only serve as ballast for the cages 5 which are going to tilt and be suspended vertically from the front flange 8, but also ensure the retention of the fuel oil, the underside of the cages 1 being covered with geotextile to filter the water. .

  Elements according to the invention, also with a bottom coated with geotextile, can be arranged along the beaches to retain the fuel oil and prevent it from passing.

  The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
