DISPOSITIF POUR REPANDRE UN MELANGE
GRAVILLONS/FIBRES ET UN LIANT SUR UN SUPPORT
La présente invention concerne un dispositif pour répandre un mélange gravillons/fibres et un liant sur un support.DEVICE FOR SPREADING A MIXTURE
GRAVILLONS / FIBERS AND A BINDER ON A SUPPORT
The present invention relates to a device for spreading a gravel / fiber mixture and a binder on a support.
Dans le domaine de la fabrication des enrobés pour les revêtements routiers, on a déjà proposé d'incorporer au mélange de granulats et de liant hydrocarboné qui forme habituellement ces enrobés, des fibres ou des lanières, par exemple en matière synthétique. L'incorporation de ces matériaux permet de former une armature qui confère à 11 enrobé répandu et compacté, une résistance accrue à la compression et à la traction. In the field of the manufacture of coated materials for road surfaces, it has already been proposed to incorporate into the mixture of aggregates and hydrocarbon binder which usually forms these coated materials, fibers or strips, for example of synthetic material. The incorporation of these materials makes it possible to form a reinforcement which confers on widespread and compacted asphalt, an increased resistance to compression and to traction.
Par ailleurs, on connaît la technique de confection des enduits qui permettent de réparer les revêtements routiers dégradés à certains endroits. Furthermore, there is a known technique for making coatings which make it possible to repair degraded road surfaces in certain places.
Le rôle des enduits est d'imperméabiliser les chaussées afin d'éviter la pénétration des eaux de pluie qui sont la cause de la plupart des déformations de la route. Ces enduits sont constitués d'une couche de bitume recouverte de granulats. The role of plasters is to waterproof pavements in order to avoid the penetration of rainwater, which is the cause of most road deformations. These plasters consist of a layer of bitumen covered with aggregates.
Du fait de leur faible épaisseur, les enduits sont fragiles et nécessitent un entretien ou un renouvellement régulier. Due to their thinness, the plasters are fragile and require regular maintenance or renewal.
Au fil du temps, les enduits sont soumis à plusieurs types de dégradations. Ainsi, il arrive que l'enduit s'arrache par plaques. On parle alors de phénomène de pelade. Over time, plasters are subject to several types of degradation. Thus, it happens that the coating tears off in plates. We then talk about the alopecia areata phenomenon.
Lorsque les gravillons se désolidarisent de l'enduit, on parle de plumage. When the gravel separates from the coating, we speak of plumage.
De plus, lorsque l'enduit perd de ses caractéristiques d'imperméabilisation, on dit que le bitume devient cassant, d'où l'apparition de fissures ou d'un faiençage. In addition, when the coating loses its waterproofing characteristics, it is said that the bitumen becomes brittle, hence the appearance of cracks or crazing.
La demanderesse a constaté que si l'on mélange aux gravillons à épandre des fibres, et que l'on répand ce mélange sur un liant, les gravillons se trouvent en quelque sorte liés les uns aux autres par les fibres qui forment une sorte de ficelle de rattachement. Ainsi, les phénomènes de plumage et de pelade sont nettement réduits. The Applicant Company has observed that if the gravel to be spread is mixed with fibers, and that this mixture is spread over a binder, the gravel is somehow linked to each other by the fibers which form a sort of string of attachment. Thus, the phenomena of plumage and alopecia are markedly reduced.
La présente invention a pour but de fournir un dispositif qui permet d'atteindre ce but. The present invention aims to provide a device which achieves this goal.
Il s'agit d'un dispositif qui est un perfectionnement des dispositifs déjà connus, de sorte qu'il est facilement adaptable sur ces derniers, sans modification majeure. It is a device which is an improvement on the devices already known, so that it is easily adaptable to the latter, without major modification.
Il s'agit donc d'un dispositif pour répandre des gravillons et un liant simultanément sur un support, notamment pour la réfection d'un revêtement routier, qui comprend une benne basculante pour la réception des gravillons, portée par un châssis mobile, et une série de trappes juxtaposées disposées au niveau de la cloison arrière de la benne, transversalement par rapport à la direction de déplacement du châssis, les trappes étant mobiles entre une position de fermeture et une position d'ouverture qui autorise le passage des gravillons et l'épandage sur le support, le dispositif comportant en outre une série de têtes de projection. It is therefore a device for spreading gravel and a binder simultaneously on a support, in particular for repairing a road surface, which comprises a tilting skip for receiving gravel, carried by a mobile chassis, and a series of juxtaposed hatches arranged at the rear bulkhead of the bucket, transversely to the direction of movement of the chassis, the hatches being movable between a closed position and an open position which allows the passage of gravel and the spreading on the support, the device further comprising a series of projection heads.
Selon l'invention, ce dispositif est caractérisé en ce qu'il est équipé de moyens de distribution de fibres, aptes à permettre l'incorporation de ces fibres dans le flux de gravillons avant leur épandage sur ledit support.According to the invention, this device is characterized in that it is equipped with fiber distribution means, capable of allowing the incorporation of these fibers into the flow of gravel before their spreading on said support.

- Figure 1 is a side view in section, of a first embodiment, in which the fiber distributor means are mounted downstream of the hatches
- Figure 2 is a view similar to Figure 1, the fiber distributing means however not being the same

Le dispositif objet de l'invention est destiné à être monté à l'arrière d'un camion représenté partiellement sur les figures annexées. Ce camion est du type comprenant un châssis mobile 1 sur lequel sont montées une citerne (non représentée) et une benne basculante 2. Cette dernière est articulée à l'arrière 10 du châssis autour d'un axe 100. Elle est destinée à recevoir des gravillons, en vue de leur épandage sur le support S, qui consiste par exemple en une chaussée détériorée. The device which is the subject of the invention is intended to be mounted at the rear of a truck shown partially in the attached figures. This truck is of the type comprising a movable chassis 1 on which are mounted a tank (not shown) and a tilting skip 2. The latter is articulated at the rear 10 of the chassis around an axis 100. It is intended to receive gravel, with a view to spreading it on the support S, which consists for example of a deteriorated pavement.
Comme cela est bien connu, à la partie inférieure de la cloison arrière 20 de la benne est monté un rouleau 5 d'entraînement des gravillons. Celui-ci est monté en rotation sur un axe transversal non représenté et est entrainé par un moteur de type connu. Son sens de rotation est symbolisé par la flèche g. As is well known, at the lower part of the rear partition 20 of the bucket is mounted a roller 5 for driving gravel. This is rotatably mounted on a transverse axis not shown and is driven by a motor of known type. Its direction of rotation is symbolized by the arrow g.
Des trappes 3 sont montées au-dessus du rouleau 5, de manière juxtaposée. Ces trappes, de type connu, sont également articulées autour d'un axe transversal et sont commandées par une série de vérins hydrauliques 4 fixés, avec articulation sur la cloison 20 de la benne. On comprend aisément que l'abaissement de ces trappes obture complètement la benne 2 tandis que leur ouverture permet l'écoulement de gravillons hors de la benne. Hatches 3 are mounted above the roller 5, juxtaposed. These hatches, of known type, are also articulated around a transverse axis and are controlled by a series of fixed hydraulic cylinders 4, with articulation on the partition 20 of the bucket. It is easily understood that the lowering of these doors completely closes the bucket 2 while their opening allows the flow of gravel out of the bucket.
A l'arrière des trappes 3 est prévue une bavette 61 transversale inclinée vers l'arrière, qui débouche sur une contre-bavette inclinée 64 faisant partie d'une passerelle 6. At the rear of the hatches 3 is provided a transverse flap 61 inclined towards the rear, which opens onto an inclined counter flap 64 forming part of a gangway 6.
La bavette 61 ainsi que la contre-bavette 64 délimitent un couloir transversal à travers lequel s'écoule le flux de gravillons G en direction du support à réparer. The flap 61 as well as the counter flap 64 delimit a transverse passage through which flows the flow of gravel G in the direction of the support to be repaired.
Ainsi que cela est bien connu, la passerelle 6 est articulée par rapport à la benne et est destinée à recevoir un opérateur. Ce dernier prend place sur la plate-forme 65. A la partie arrière de cette passerelle est fixée une rampe comprenant une série de buses de distribution de liant 60 disposées transversalement. Un poste de commande, qui comprend notamment un volant 62 et une série de manettes 63, permet à l'opérateur de piloter ltouverture/fermeture des trappes 3 et des buses 60. As is well known, the gangway 6 is articulated relative to the bucket and is intended to receive an operator. The latter takes place on the platform 65. At the rear part of this gangway is fixed a ramp comprising a series of binder distribution nozzles 60 arranged transversely. A control station, which in particular comprises a steering wheel 62 and a series of joysticks 63, allows the operator to control the opening / closing of the hatches 3 and of the nozzles 60.
Le plus souvent, il est prévu le même nombre de buses de projection de liant que de trappes 3 de sorte qu'il est possible de sélectionner la localisation des trappes et des buses à actionner en fonction de l'étendue et de l'emplacement de l'épandage à effectuer. Most often, the same number of binder projection nozzles is provided as with hatches 3 so that it is possible to select the location of the hatches and of the nozzles to be actuated as a function of the extent and location of the spreading to be carried out.
Selon l'invention, ce dispositif comporte des moyens aptes à permettre l'incorporation de fibres dans le flux de gravillons avant l'épandage sur le support S. According to the invention, this device comprises means capable of allowing the incorporation of fibers in the flow of gravel before spreading on the support S.
Dans la forme de réalisation de la figure 1, ces moyens comportent un caisson 70 qui dans sa partie supérieure, a la forme d'une boîte parallèlépipèdique qui repose, par sa face inférieure, sur les cloisons latérales 23 de la benne. In the embodiment of Figure 1, these means comprise a box 70 which in its upper part, has the shape of a parallelepiped box which rests, by its lower face, on the side walls 23 of the bucket.
En cas de besoin, une plaque transversale 21 est fixée sur ces parois latérales de manière à assurer la retenue supplémentaire du caisson. If necessary, a transverse plate 21 is fixed on these side walls so as to provide additional retention of the box.
La partie supérieure en forme de boîte, qui est munie d'un couvercle articulé 75, comporte une partie inférieure en forme de goulotte 71 dont l'ouverture inférieure 710 débouche à proximité de la bavette 61 et de la contre-bavette 64.The upper box-shaped part, which is provided with an articulated cover 75, comprises a lower part in the form of a trough 71, the lower opening 710 of which opens near the flap 61 and the counter flap 64.
A l'intérieur du caisson sont montées deux séries de bobines B et B' de fibres synthétiques. I1 s'agit par exemple de fibres de verre. Inside the box are mounted two sets of coils B and B 'of synthetic fibers. These are, for example, glass fibers.
Ces bobines sont montées chacune sur un axe 72. Les bobines
B' sont prévues à titre de stockage.These coils are each mounted on an axis 72. The coils
B 'are provided for storage.
De préférence, il est prévu autant de bobines B que de trappes 3. Preferably, as many coils B are provided as there are hatches 3.
Chaque bobine B est préférentiellement associée à un pistolet coupeur et projeteur 8 fixé, par tout moyen approprié, à une paroi du caisson. I1 s'agit d'un matériel de type connu, par exemple pneumatique, qui a pour fonction de couper en petits tronçons le fil de fibre F qui provient de la bobine B et de le projeter sous forme de petits morceaux vers l'ouverture inférieure 710 de la goulotte 71. La structure exacte de ce type de pistolet ne sera pas décrite car elle est connue en soi. Each coil B is preferably associated with a cutter and spray gun 8 fixed, by any suitable means, to a wall of the box. It is a material of known type, for example pneumatic, which has the function of cutting the fiber thread F from the coil B into small sections and projecting it in the form of small pieces towards the lower opening. 710 of chute 71. The exact structure of this type of gun will not be described because it is known per se.
On comprend donc que lorsque l'on actionne les trappes 3 dans le sens de leur ouverture et que l'on met en route les pistolets 8 on peut épandre sur le support S à recouvrir, un mélange de fibres et de gravillons. It is therefore understood that when the hatches 3 are actuated in the direction of their opening and when the pistols 8 are started, it is possible to spread on the support S to be covered, a mixture of fibers and gravel.
Dans la variante de réalisation de la figure 2, le caisson 70 renferme un certain volume de fibres déjà coupées F. I1 est prévu dans la partie supérieure de la goulotte 71 des petites cloisons 73 formant entonnoir, qui débouchent sur un rouleau rotatif 74 adapté pour permettre l'écoulement régulier de fibres coupées F vers l'extrémité inférieure 710 de la goulotte. Il est prévu, de préférence, autant "d'entonnoirs" et de rouleaux 74 qu'il y a de trappes 3. Avantageusement, l'entraînement en rotation de ces rouleaux est couplé avec l'ouverture des trappes 3. In the alternative embodiment of FIG. 2, the box 70 contains a certain volume of fibers already cut F. I1 is provided in the upper part of the chute 71 of the small partitions 73 forming a funnel, which lead to a rotary roller 74 suitable for allow the regular flow of cut fibers F towards the lower end 710 of the chute. There are preferably provided as many "funnels" and rollers 74 as there are hatches 3. Advantageously, the rotary drive of these rollers is coupled with the opening of the hatches 3.
Dans la variante de réalisation de la figure 3, le caisson 70' a la même structure que celle déjà décrite. Toutefois, la partie en forme de goulotte 71' est montée à l'intérieur même de la benne. Cette goulotte comprend une paroi 74' qui sépare la masse de gravillons G contenue dans la benne, du flux de fibres F. Celles-ci sont mélangées avec les gravillons G juste avant leur passage au travers des trappes 3. In the alternative embodiment of Figure 3, the box 70 'has the same structure as that already described. However, the chute-shaped part 71 'is mounted inside the bucket itself. This chute comprises a wall 74 ′ which separates the mass of gravel G contained in the bucket, from the flow of fibers F. These are mixed with the gravel G just before their passage through the hatches 3.
Dans cet exemple de réalisation, les moyens qui permettent de couper les fibres provenant des bobines B en petits morceaux, et de les projeter consistent en deux rouleaux rotatifs juxtaposés 73' comportant des moyens de coupe telle que des lames. Ces rouleaux sont entraînés en rotation, par exemple, par un moteur électrique, dont la mise en route est associée à l'ouverture des trappes 3. I1 est prévu, de préférence, autant de paires de rouleaux 73' que de trappes 3. In this exemplary embodiment, the means which make it possible to cut the fibers coming from the coils B into small pieces, and to project them consist of two juxtaposed rotary rollers 73 ′ comprising cutting means such as blades. These rollers are driven in rotation, for example, by an electric motor, the start-up of which is associated with the opening of the hatches 3. There are preferably provided as many pairs of rollers 73 ′ as hatches 3.
Enfin, dans l'exemple de réalisation de la figure 4, la benne 2 comporte un faux-plancher 22 en-dessous duquel est prévu un tapis convoyeur sans fin mobile 9 sur lequel est déversé continuellement, par des moyens adéquats, un certain volume de fibres coupées F. Le faux-plancher 22 s'interrompt juste à proximité des trappes 3 de sorte que lorsque le tapis convoyeur se déplace dans le sens de la flèche f, des fibres sont acheminées vers les trappes 3 et mélangées au flux de gravillons. Finally, in the embodiment of Figure 4, the bucket 2 has a raised floor 22 below which is provided a movable endless conveyor belt 9 on which is continuously discharged, by suitable means, a certain volume of cut fibers F. The false floor 22 is interrupted just near the doors 3 so that when the conveyor belt moves in the direction of arrow f, fibers are conveyed to the doors 3 and mixed with the gravel flow.
On s'est aperçu que la rencontre des fibres et des gravillons, que ce soit au passage des trappes 3 ou dans le couloir formé par la bavette 61 et la contre-bavette 64, suffit pour former un mélange suffisamment homogène pour la réalisation de l'enduit de réparation du support S. It has been found that the meeting of the fibers and the gravel, either at the passage of the hatches 3 or in the corridor formed by the flap 61 and the counter flap 64, is sufficient to form a sufficiently homogeneous mixture for the realization of the repair coating of support S.
Bien entendu, si la réfection de la chaussée ne doit être faite que sur une certaine partie de celle-ci, il suffira de mettre en route les têtes de projection de liant seulement nécessaires pour ce faire, de même que les trappes 3 ainsi que les moyens de distribution et/ou de coupe de fibres correspondants. Of course, if the repair of the roadway should only be done on a certain part of it, it will suffice to start the binder projection heads only necessary to do this, as well as the hatches 3 and the means for distributing and / or cutting corresponding fibers.
Cette opération est effectuée de manière connue, c'est-à-dire en déplaçant le dispositif dans le sens de la flèche h. Un voile de liant est déposé par les buses 60 sur le suport S et est immédiatement recouvert d'un mélange de gravillons et de fibres. This operation is carried out in a known manner, that is to say by moving the device in the direction of the arrow h. A veil of binder is deposited by the nozzles 60 on the support S and is immediately covered with a mixture of gravel and fibers.
A titre indicatif, on fournit environ 50 à 100 grammes de fibres pour environ 10 kilogrammes de gravillons. As an indication, approximately 50 to 100 grams of fiber are supplied for approximately 10 kilograms of gravel.
Le dispositif de l'invention peut ainsi être utilisé sans modification majeure du matériel existant et permet de réaliser des enduits de bonne qualité. The device of the invention can thus be used without major modification of the existing equipment and makes it possible to produce coatings of good quality.
Ainsi, on constate que les gravillons ne se décollent pratiquement pas du support. De plus, les bruits de roulement provenant de l'enduit sont attenués du fait que les fibres forment une isolation plastique qui évite que les gravillons ne s'entrechoquent. Thus, it can be seen that the gravel practically does not come off the support. In addition, the rolling noises coming from the plaster are attenuated because the fibers form a plastic insulation which prevents the gravel from colliding.
