Description

Machine finisseuse niveleuse multifonction pour la construction de remblais routiers et autres Multifunctional grader-finishing machine for the construction of road embankments and others
DESCRIPTION La présent invention a pour objet une machine finisseuse niveleuse multifonction pour la construction d'un remblais routier et autres.DESCRIPTION The present invention relates to a multifunctional grader-leveler machine for the construction of a road embankment and the like.
Le secteur technique de l'invention est le domaine des travaux publics et de la construction de matériels pour ces travaux. Une des applications principales de l'invention est la réalisation des remblais routiers, des aéroports, des digues en terre, des fondations en sols stabilisés.The technical sector of the invention is the field of public works and the construction of materials for this work. One of the main applications of the invention is the production of road embankments, airports, earth dikes, foundations in stabilized soils.
Pour réaliser des terre-pleins, des terrains de sports et tous autres travaux de génie civil, on procède généralement à l'épandage d'une couche de terre ou autres matériaux appelés tout venant, qui est un mélange de sable, de terre et de cailloux de petites tailles. L'ensemble mélangé est étalé, puis comprimé et damé par des machines de compression ou des compacteurs pour consolider.To make medians, sports grounds and all other civil engineering works, we generally spread a layer of earth or other materials called all comers, which is a mixture of sand, earth and small stones. The mixed whole is spread out, then compressed and packed by compression machines or compactors to consolidate.
Après consolidation d'une couche grâce à tout moyen de compression, on étend sur elle une autre couche qui est compactée à son tour et ainsi de suite jusqu'à la formation d'un remblai complet.After consolidation of a layer using any means of compression, another layer is spread over it which is in turn compacted and so on until the formation of a complete embankment.
La terre employée à cet effet peut être de la terre naturelle ou mélangée avec des additifs formant liants et elle peut provenir d'une carrière effectuée à proximité du remblai ou elle peut au contraire provenir de carrières situées à plus grande distance.The earth used for this purpose can be natural earth or mixed with additives forming binders and it can come from a quarry carried out near the embankment or it can on the contrary come from quarries located at greater distance.
Dans le premier cas, l'opération d'épandage et par conséquent de formation de la couche, est généralement exécutée par une seule machine appelée décapeuse, ou "scraper".In the first case, the spreading operation and consequently of the layer formation, is generally carried out by a single machine called scraper, or "scraper".
Dans le second cas, le transport des matériaux s'effectue au moyen de camions basculants ou "dampers" qui déversent les matériaux sur la plate-forme en formant des tas plus ou moins épais répartis selon l'épaisseur de la couche qu'on veut réaliser.In the second case, the transport of the materials is carried out by means of tilting trucks or "dampers" which dump the materials on the platform by forming more or less thick piles distributed according to the thickness of the layer which one wants achieve.
Dans le second cas très fréquent, les tas laissés par les camions qui ont basculés les matériaux doivent être dégrossis une première fois par une première machine appelée bouteur ou"bulldozer" , puis une seconde opération qui consiste à aplanir avec précision. Ce dernier travail est exécuté par une machine niveleuse légère sur roues caoutchoutées possédant un châssis muni d'une lame au centre et s'étendant à l'avant jusqu'à un moyen de contact avec le sol : en général, ceux sont deux roues situées à l'extrémité la plus en avant du châssis et devant la lame. Après épandage et aplanissage de la couche de terre, cette couche se trouve à l'état mou et elle est soumise à l'action de compression, de damage et/ou de compactage par des moyens conçus à cet effet, et elle ne sera considérée comme achevée que lorsque la densité de la couche aura atteint ou dépassé des valeurs prescrites déterminées.In the second very frequent case, the heaps left by the trucks that have tipped the materials must be roughed out first by a first machine called bulldozer, then a second operation which consists in flattening with precision. This last work is carried out by a light leveling machine on wheels rubberized having a chassis provided with a blade in the center and extending at the front to a means of contact with the ground: in general, those are two wheels located at the most forward end of the chassis and in front the blade. After spreading and leveling the layer of soil, this layer is in the soft state and it is subjected to the action of compression, tamping and / or compacting by means designed for this purpose, and it will not be considered as complete only when the density of the layer has reached or exceeded determined prescribed values.
Le procédé classique ci-dessus exposé comporte l'emploi de diverses machines et son exécution complète demande un temps important.The conventional process described above involves the use of various machines and its complete execution requires a significant time.
Le problème posé est de réaliser des remblais suivant les opérations décrites ci-dessus grâce à une seule machine multifonction qui assure certaines de ce opérations simultanément, ou l'une après l'autre suivant la nécessité des travaux.The problem is to make embankments according to the operations described above using a single multifunction machine which performs some of these operations simultaneously, or one after the other depending on the need for the work.
Une solution au problème posé est une machine appelée finisseuse niveleuse multifonction qui peut être automotrice, pour réaliser la construction des chaussées, de parkings, des terrains de sports et espaces verts et, qui répande, malaxe, dame, nivelle, vibre et lisse les matériaux qu'elle reçoit.A solution to the problem posed is a machine called a multifunctional leveler-finisher which can be self-propelled, to carry out the construction of roadways, parking lots, sports grounds and green spaces and, which spreads, mixes, grooms, levels, vibrates and smoothes materials that she receives.
La machine automotrice multifonction selon l'invention comporte un châssis supportant une trémie basculante,à fond plat, dans laquelle sont déversées différents matériaux tels que terre, tout venant, grave, ciment, pouzzolane, enrobés, chyste, ceux-ci glissant dans le sens opposé de la marche, et des portes de retenue s'ouvrant à la demande pour un débit proportionnel à la couche de matériau à répandre.
