Description

La présente invention se rapporte au domaine de la protection de l'environnement.The present invention relates to the field of environmental protection.

Elle a plus particulièrement pour objet un moyen de protection pour glissières métalliques et notamment pour les glissières de sécurité disposées le long des voies de circulation.It relates more particularly to a means of protection for metal slides and especially for the safety barriers placed along the traffic lanes.

L'invention a spécifiquement pour objet un moyen de désherbage ou de lutte contre la pousse de la végétation pour glissières de sécurité, qui empêche la pousse de l'herbe ou évite le développement de l'herbe autour des portions de terre végétale située sous et en dehors des glissières de sécurité, qui consiste à placer à un tel endroit un ruban de caoutchouc non vulcanisé présentant une épaisseur importante mais suffisamment souple pour se plaquer sur le sol ou dans le sol et absorber les dénivellations ou les montuosités du relief.The subject of the invention is specifically a means of weeding or fighting against growth. Vegetation for safety barriers, which prevents the growth of grass or prevents grass development around the portions of topsoil below and outside the safety barriers, which consists in placing in such a place a rubber band not vulcanized with a significant thickness but flexible enough to be pressed onto the ground or in the ground and absorb the unevenness or the montuosities of the relief.

On connaít l'importance prise par la pose de glissières de sécurité, en bois ou surtout en métal, en bordure généralement de voies de circulation, principalement des voies de circulation à grande vitesse ou encore des routes, pour réduire les dangers dus à la circulation.We know the importance taken by the installation of safety barriers, wooden or especially in metal, generally bordering traffic lanes, mainly traffic lanes high speed traffic or roads, to reduce the dangers due to traffic.

Ces glissières sont supportées par des poteaux espacés à des intervalles de 4 m environ sur des tronçons de voie droits et de 2 m dans des tronçons de voie plus sinueux ou plus particulièrement exposés à des risques de chocs (courbes, virages répétés et dangereux, présence d'arbres à proximité de la voie...).These slides are supported by posts spaced at intervals of about 4 m on straight and 2 m sections of track in more or more winding sections of track particularly exposed to shock risks (curves, repeated and dangerous turns, presence of trees near the track ...).

Dans le plus grand nombre de cas, ces poteaux servent de support et sont disposés sur le bas-côté de la chaussée. L'herbe peut ainsi se développer au pied et sur le pourtour des dits poteaux. Il devient alors nécessaire de procéder à la tonte de l'herbe qui a ainsi poussé, en général 2 à 3 fois par an. Cette opération est souvent difficile et risquée car elle peut représenter un danger pour le personnel d'entretien. La conséquence en est qu'il est souvent nécessaire de neutraliser la voie de circulation pendant le temps où la faucheuse opère.In the greatest number of cases, these posts serve as support and are arranged on the aisle of the roadway. The grass can thus develop at the foot and around the edges of the so-called posts. It then becomes necessary to mow the grass which has thus grown, in general 2 to 3 times a year. This operation is often difficult and risky because it can represent a danger for maintenance personnel. The consequence is that it is often necessary to neutralize the taxiway during the time the mower is operating.

L'art antérieur décrit déjà des dispositifs de sécurité sous forme de poteaux ou de collerettes disposées sur le sol par l'intermédiaire d'une plaque au niveau du sol ou en dessous du niveau du sol et comportant une ouverture ou une déchirure emboítée et s'étendent vers l'angle externe du feuillet de matériau (brevet US 3.704.004) ou (demande de brevet allemand DE 1 9958 581 A1) sur la plaque.
De cette façon des poteaux et en particulier les supports de barrière peuvent être disposés sur le sol et y être fixés solidement.The prior art already describes safety devices in the form of posts or flanges arranged on the ground by means of a plate at ground level or below ground level and comprising an opening or a torn socket and s 'extend towards the outer corner of the material sheet (US patent 3,704,004) or (German patent application DE 1 9958 581 A1) on the plate.
In this way posts and in particular the barrier supports can be arranged on the ground and be fixed there securely.

L'intérêt de tels dispositifs est décrit comme étant de nature à empêcher des graines de tomber sur le sol immédiatement adjacent au poteau et ainsi d'interdire la pousse d'une quelconque végétation entre le poteau et la bague de sol.The advantage of such devices is described as being able to prevent seeds from falling. on the ground immediately adjacent to the pole and thus prohibit the growth of any vegetation between the post and the ground ring.

L'invention vise donc à fournir un moyen qui permet d'éviter la tonte de l'herbe sous la glissière sans comporter de risque pour le personnel d'entretien des routes.The invention therefore aims to provide a means which makes it possible to avoid mowing the grass under the slide without risk to road maintenance personnel.

Le problème technique ainsi posé à été résolu conformément à l'invention par application sur la terre, au pied ou en dessous des poteaux de rail de sécurité, de caoutchouc cru sous forme d'un ruban ou d'une bande que l'on déroule au pied de la glissière ou que l'on insère sur le pied de la glissière ou que l'on insère dans une tranchée ouverte au droit des plots porteurs du rail de sécurité. Le caoutchouc cru, donc non vulcanisé - ainsi utilisé est d'une grande souplesse, s'applique avec facilité sur le sol et y reste adhérent du fait de sa densité et de son poids.The technical problem thus posed was solved in accordance with the invention by application to the ground, at the foot or below the posts of the safety rail, of raw rubber in the form a ribbon or strip which is unrolled at the bottom of the slide or which is inserted on the foot of the slide or that is inserted into an open trench to the right of the bearing pads of the safety rail. Raw rubber, therefore unvulcanized - thus used is of great flexibility, applies with ease on the ground and remains adherent to it because of its density and weight.

Il est donc possible de mettre en place un tel ruban de caoutchouc et d'y insérer ensuite par perforation les pieds de glissière.It is therefore possible to set up such a rubber band and then insert it by perforation of the slide feet.

Ainsi, la pousse et le développement de l'herbe sur la bande de terre végétale recouverte sur une largeur appropriée, sont rendus impossible par suite de l'occultation quasi complète à la lumière.Thus, the growth and development of the grass on the strip of topsoil covered on an appropriate width, are made impossible as a result of the almost complete concealment of the light.

Il est également possible que le ruban soit découpé en demi-lunes que l'on assemble après pose sur le sol.It is also possible that the ribbon is cut in half-moons which we assemble after laying on the ground.

En outre sous l'effet de la température et de la chaleur naturelle liée au climat, le caoutchouc cru se vulcanise en l'espace de quelques mois en une période de 15 jours à 6 mois (± 1 mois), en fonction de la température extérieure, et de ce fait, les défauts présentés par le relief sont aplanis simultanément. In addition, under the effect of temperature and the natural heat linked to the climate, rubber cru vulcanizes within a few months in a period of 15 days to 6 months (± 1 month), depending on the outside temperature, and therefore, the defects presented by the relief are flattened simultaneously.

Une particularité du caoutchouc cru non vulcanisé consiste dans le fait qu'il contient une forte proportion de caoutchouc issu du recyclage des pneumatiques usagés, de l'ordre de 10 à 90 % de caoutchouc recyclé et de préférence de 20 à 40 % de caoutchouc recyclé.A special feature of unvulcanized raw rubber is that it contains a high proportion of rubber from the recycling of used tires, of the order of 10 to 90% recycled rubber and preferably 20 to 40% recycled rubber.

Le mélange proposé selon l'invention permet aussi d'incorporer au caoutchouc cru non vulcanisé, une quantité notable de déchets de matières plastiques allant de 0 à 30 %. Par extrusion on obtient un mélange composé de différentes qualités de caoutchouc et comportant une teneur déterminée en matières plastiques. Néanmoins, cette adjonction ne constitue pas une mesure préférée.The mixture proposed according to the invention also makes it possible to incorporate raw rubber not vulcanized, a significant amount of plastic waste ranging from 0 to 30%. Through extrusion is obtained a mixture composed of different qualities of rubber and comprising a specific content of plastics. However, this addition does not constitute a preferred measure.

Un caoutchouc cru non vulcanisé ainsi préparé peut se présenter, après extrusion ou laminage, sous forme d'un ruban d'une largeur comprise entre 50 et 70 cm, (±10 %) de préférence de 50 cm et d'une épaisseur variant de 7 à 15 mm (± 3 mm), en moyenne d'environ 10 mm. Le ruban ainsi préparé, est présenté en rouleaux continus d'une longueur atteignant 10 à 100 m (± 10 %).Unvulcanized raw rubber thus prepared may appear, after extrusion or rolling, in the form of a ribbon with a width of between 50 and 70 cm, (± 10%) preferably 50 cm and with a thickness varying from 7 to 15 mm (± 3 mm), on average about 10 mm. The tape thus prepared, is presented in continuous rolls up to 10 to 100 m long (± 10%).

Le déroulement d'un tel ruban et sa fixation au sol au pied ou autour des poteaux permet de réaliser une couverture souple du sol. La présence dans le mélange de caoutchouc, d'accélérateurs de vulcanisation, permet la vulcanisation du caoutchouc en quelques mois. Il devient de plus en plus dur, tout en restant plastique, ce qui lui permet de demeurer appliqué sur les inégalités de la surface à couvrir.The unwinding of such a tape and its attachment to the ground at the foot or around the posts makes it possible to provide flexible ground cover. The presence in the rubber mixture, vulcanization accelerators, allows the vulcanization of rubber in a few months. he becomes harder and harder, while remaining plastic, allowing it to remain applied on the unevenness of the surface to be covered.

Le dispositif selon l'invention comporte l'avantage de constituer une solution définitive contre la pousse de l'herbe, de protéger les voies de circulation contre l'accumulation d'eau, dangereuse pour les utilisateurs de véhicules à deux roues, d'éviter au personnel d'entretien des voies rapides de se mettre en situation dangereuse pour le fauchage et d'éviter lors des opérations de désherbage, les rétrécissements de voie qui sont gênants pour le trafic automobile.The device according to the invention has the advantage of constituting a final solution against grass growth, protect traffic lanes against water accumulation, dangerous for users of two-wheeled vehicles, avoid maintenance personnel expressways to put themselves in a dangerous situation for mowing and to avoid during weeding operations, the narrowing of the lane which is inconvenient for traffic automobile.

Le produit selon l'invention comprend ainsi le grand avantage d'inclure des quantités notables de produits de recyclage et contribue ainsi à la protection de l'environnement. The product according to the invention thus includes the great advantage of including notable quantities. of recycling products and thus contributes to environmental protection.

L'invention a pour objet l'utilisation du caoutchouc cru non vulcanisé selon l'invention pour la protection et le désherbage des panneaux de signalisation. Les rubans de caoutchouc disposés au pied du support de panneau de signalisation empêchent la végétation de se développer et une telle pose évite qu'il soit nécessaire d'avoir recours au désherbage. A cette fin le ruban de caoutchouc est déroulé et planté au pied du support de panneau. Le support de panneau est constitué d'une tige quadrangulaire ou circulaire, enfoncée dans le sol ou disposée dans un fourreau disposé dans le sol.The subject of the invention is the use of unvulcanized raw rubber according to the invention for the protection and weeding of traffic signs. The rubber ribbons arranged at the foot of the sign holder prevent vegetation from growing and such a pose avoids the need for weeding. To this end the ribbon of rubber is unrolled and planted at the foot of the panel support. The panel support is consisting of a quadrangular or circular rod, sunk into the ground or arranged in a scabbard placed in the ground.

Pour éviter le développement de la végétation à cet endroit, le ruban de caoutchouc est posé sur ou enfoncé dans le sol autour du support de panneau de signalisation. L'optimum d'efficacité se trouve, lors de la pose au sol de panneaux de signalisation, de placer à ce moment sur le sol ou dans le sol autour du support, un segment du ruban de caoutchouc. Pour ce faire, on opère dans le ruban une ouverture suffisamment large pour que le ruban de caoutchouc puisse être mis en place disposé autour des supports, au pied du support ou à cheval ou bien découpé en deux parties égales ou non, enserrant le support.To avoid the development of vegetation at this location, the rubber band is laid on or sunk into the ground around the sign holder. The optimum When installing signboards on the ground, it is effective to place moment on the ground or in the ground around the support, a segment of the rubber band. For To do this, we operate an opening in the ribbon that is large enough for the ribbon to rubber can be placed arranged around the supports, at the foot of the support or at horse or cut into two equal or unequal parts, enclosing the support.

Dans un mode d'exécution préféré le ruban peut présenter des encoches dans lesquelles on fait pénétrer le support. Ces encoches disposées dans le ruban peuvent être partielles ce qui veut dire qu'on met en place le ruban de caoutchouc sur le sol ou dans le sol puis on dispose à cet endroit des fragments de caoutchouc déjà découpés ou bien encore un ruban entier qui sera placé à la base du support du panneau de signalisation. Le ruban est ensuite laissé à même le sol ou légèrement enfoui dans une tranchée puis il est recouvert de sable ou de terre légère pour en garantir la mise en place.In a preferred embodiment, the ribbon may have notches in which it is made penetrate the support. These notches arranged in the ribbon can be partial which means say that we put the rubber band on the ground or in the ground then we have this place of the rubber fragments already cut or even an entire ribbon which will be placed at the base of the sign holder. The ribbon is then left on the ground or lightly buried in a trench then it is covered with sand or light earth to guarantee its implementation.
