Description

La présente invention concerne une machine autopropulsée pour bétonner des fossés, du type comprenant un groupe de propulsion entraînant des moyens de déplacement de la machine et un système d'épandage d'une couche de béton sur le fond et sur les bords du fossé au fur et à mesure de l'avance de la machine.The present invention relates to a self-propelled machine for concreting ditches, of the type comprising a propulsion unit driving means for moving the machine and a system for spreading a layer of concrete on the bottom and on the edges of the ditch as and as the machine advances.

Dans le document DE-A-3.031.688, qui sert de base au préambule de la revendication 1, on décrit une machine autopropulsée apte à déposer une couche de béton sur le sol et lui donner simultanément le profil désiré, cette machine comprenant une trémie à béton qui communique directement avec un dispositif de conformation qui a la forme de la surface extérieure de la couche de béton à conformer par une ouverture située à la partie inférieure de la trémie, cette machine comportant en outre des moyens de support constitués par des roues ou des patins prenant appui sur le sol pour permettre le déplacement de ladite machine, et un groupe de propulsion entraînant des moyens de déplacement de ladite machine. En fait, ce groupe de propulsion est constitué par un poussoir à mouvement alternatif qui presse le béton déposé dans le conformateur et déplace la machine vers l'avant lors de sa course vers l'arrière. Dans le cas où le béton est à mettre en place dans un fossé, il est prévu qu'au moins certains des moyens de support se déplacent sur les bords supérieurs du fossé.In document DE-A-3,031,688, which serves as a basis for the preamble of claim 1, a self-propelled machine is described capable of depositing a layer of concrete on the ground and simultaneously giving it the desired profile, this machine comprising a hopper to concrete which communicates directly with a shaping device which has the shape of the outer surface of the concrete layer to be conformed by an opening located at the bottom of the hopper, this machine further comprising support means constituted by wheels or pads bearing on the ground to allow the movement of said machine, and a propulsion unit driving means for moving said machine. In fact, this propulsion unit consists of a reciprocating pusher which presses the concrete deposited in the shaper and moves the machine forward during its stroke backwards. In the case where the concrete is to be placed in a ditch, it is expected that at least some of the support means move on the upper edges of the ditch.

La présente invention a pour but de fournir une machine destinée à bétonner un fossé creusé dans le sol et comportant un fond essentiellement plan et horizontal et deux bords inclinés, cette machine bétonnant à la fois le fond et les côtés du fossé sans exiger la présence de chemin de déplacement pour des moyens de support sur les bords supérieurs du fossé, cette machine pouvant se déplacer de façon continue.The object of the present invention is to provide a machine intended for concreting a ditch dug in the ground and comprising an essentially flat and horizontal bottom and two inclined edges, this machine concreting both the bottom and the sides of the ditch without requiring the presence of movement path for support means on the upper edges of the ditch, this machine being able to move continuously.

Pour obtenir ce résultat, la machine selon l'invention présente les particularités contenues dans la partie caractérisante de la revendication 1.To obtain this result, the machine according to the invention has the features contained in the characterizing part of claim 1.

Selon un mode préférentiel de réalisation, les moyens de déplacement de la machine sont constitués par au moins une chenille qui avance sur le fond du fossé.According to a preferred embodiment, the means for moving the machine consist of at least one track which advances on the bottom of the ditch.

Selon une autre disposition de l'invention, le système d'épandage, situé vers l'arrière de la machine, est tiré par la chenille en prenant notamment appui sur la couche de béton qui vient d'être déposée à l'arrière de la machine.According to another arrangement of the invention, the spreading system, located towards the rear of the machine, is pulled by the track, in particular by resting on the layer of concrete which has just been deposited at the rear of the machine.

Le système d'épandage comprend essentiellement une trémie de stockage du béton, une vis sans fin dans le fond de la trémie pour acheminer le béton dans un coffrage épousant la forme du fossé, ce coffrage comprenant une ouverture inférieure en regard du fond du fossé et par laquelle le béton tombe par gravité pour former la couche de béton de fond, cette ouverture inférieure étant prolongée par deux ouvertures latérales situées en regard des bords du fossé et par lesquelles le béton est projeté, au moyen d'ailettes entraînées à rotation par la vis sans fin, pour former les couches de béton latérales.The spreading system essentially comprises a concrete storage hopper, a worm screw in the bottom of the hopper for conveying the concrete in a formwork conforming to the shape of the ditch, this formwork comprising a lower opening facing the bottom of the ditch and by which the concrete falls by gravity to form the bottom concrete layer, this lower opening being extended by two lateral openings located opposite the edges of the ditch and through which the concrete is sprayed, by means of fins driven in rotation by the auger, to form the lateral concrete layers.

Le système d'épandage est complété par des moyens de compression, tels une plaque à section trapézoïdale qui comprime simultanément les couches de béton déposées sur le fond et sur les bords du fossé, cette plaque servant également de surface d'appui pour le système d'épandage au cours de l'avance de la machine.The spreading system is supplemented by compression means, such as a trapezoidal section plate which simultaneously compresses the layers of concrete deposited on the bottom and on the edges of the ditch, this plate also serving as a bearing surface for the d spreading during machine advance.

Selon un autre avantage de l'invention, la machine guidée par la chenille peut suivre un tracé quelconque, en particulier à forte pente et dans des terrains accidentés.According to another advantage of the invention, the machine guided by the track can follow any route, in particular with a steep slope and in rough terrain.

Selon encore un autre avantage de l'invention, la machine est compacte et de petites dimensions, ce qui facilite son transport sur les sites d'utilisation.According to yet another advantage of the invention, the machine is compact and of small dimensions, which facilitates its transport to the sites of use.

Cette ouverture 12 est délimitée par les bords inférieurs horizontaux 13a , 14a, de deux parois verticales avant 13 et arrière 14, parallèles, espacées et s'étendant perpendiculairement à l'axe longitudinal de la machine 1. Ces bords inférieurs 13a , 14a s'étendent sur une longueur correspondant sensiblement a la largeur du fond FF du fossé F et sont situés à une hauteur h de celui-ci. Le coffrage 11 présente egalement deux ouvertures latérales 15 qui prolongent latéralement l'ouverture centrale 12. Chaque ouverture latérale 15 s'étend en largeur entre les deux parois avant 13 et arrière 14 , et en hauteur sur une longueur correspondant sensiblement à la hauteur du bord latéral adjacent BF du fosse à bétonner . Chaque ouverture latérale 15 est située dans un plan sensiblement parallèle au bord BF du fossé adjacent et à une distance de celui-ci définie par les bords inclinés 13b , 14b des deux plaques avant 13 et arriere 14, qui sont separés d'une distance d du bord BF du fossé F. Chaque ouverture latérale 15 est associee à un volet 15a monté coulissant dans le plan de l'ouverture 15 pour modifier sa section de passage selon la hauteur de bétonnage du bord BF adjacent du fossé F, comme representé schématiquement à la figure 3.The formwork 11, with reference to FIGS. 1 and 3, has a lower central opening 12 situated opposite the bottom FF of the ditch F. This opening 12 is delimited by the horizontal lower edges 13 a , 14 a , of two vertical front 13 and rear 14 walls, parallel, spaced and extending perpendicular to the longitudinal axis of the machine 1. These lower edges 13 a , 14 to extend over a length substantially corresponding to the bottom width of the gap F and FF are located at a height h thereof. The formwork 11 also has two lateral openings 15 which laterally extend the central opening 12. Each lateral opening 15 extends in width between the two front 13 and rear 14 walls, and in height over a length corresponding substantially to the height of the edge lateral adjacent BF of the pit to be concreted. Each lateral opening 15 is located in a plane substantially parallel to the edge plane of the adjacent BF gap and at a distance thereof defined by the inclined edges 13 b, 14 b of the front pair 13 and rear 14, which are separated by a distance d from the edge BF of the ditch F. Each lateral opening 15 is associated with a flap 15a mounted sliding in the plane of the opening 15 to modify its cross-section according to the concreting height of the edge BF adjacent to the ditch F, as shown schematically in Figure 3.

Le béton déversé et stocké dans la trémie 10 est acheminé dans le coffrage 11 au moyen d'une vis sans fin 20 située dans le fond de la trémie 7 et s'étendant suivant l'axe de la machine 1. Cette vis sans fin 20 est supportée à rotation a ses deux extrémités par deux paliers 21a , 21b fixés aux deux parois transversales d'extrémité de la trémie 10 . A son extrémité arrière, la vis sans fin 20 traverse la paroi d'extrémité arrière 14 du coffrage 11 pour être entrainée en rotation par un moteur hydraulique auxiliaire M2 alimenté à partir de la pompe P1 . Au niveau du coffrage 11, la vis sans fin 20 supporte à rotation deux ailettes 22 qui brassent la béton pour le projeter latéralement sur les bords BF du fosse F par les ouvertures latérales 15 . Le coffrage 11 étant ouvert à sa partie supérieure correspondant à la partie arrière de la tremie 10, il est prévu un déflecteur 24 pour éviter que le béton brassé par les ailettes 22 ne soit éjecté a l'extérieur du coffrage 11 (figure 1) .The concrete poured and stored in the hopper 10 is conveyed in the formwork 11 by means of an endless screw 20 situated in the bottom of the hopper 7 and extending along the axis of the machine 1. This endless screw 20 is rotatably supported at its two ends by two bearings 21 a , 21 b fixed to the two transverse end walls of the hopper 10. At its rear end, the worm 20 passes through the rear end wall 14 of the formwork 11 to be driven in rotation by an auxiliary hydraulic motor M2 supplied from the pump P1. At the level of the formwork 11, the endless screw 20 rotatably supports two fins 22 which mix the concrete to project it laterally on the edges BF of the pit F through the lateral openings 15. The formwork 11 being open at its upper part corresponding to the rear part of the hopper 10, a deflector 24 is provided. to prevent the concrete stirred by the fins 22 from being ejected outside the formwork 11 (Figure 1).

Le système de compression et de lissage 5, figures 1 et 5, est formé par une plaque 25 de section trapézoïdale légèrement inclinée de l'avant vers l'arrière. Cette plaque 25 est fixée, par une extrémité ou extrémité avant , à la base de la paroi arrière 14 du coffrage 11. La distance séparant le bord arrière de cette plaque 25 du fossé F fixe les épaisseurs des couches de béton sur le fond FF et sur les bords latéraux BF du fossé F. La plaque 25 comprend une partie centrale 25a en regard du fond FF du fossé et deux parties latérales inclinées 25b parallèles aux bords BF du fossé F. Les parties inclinées 25b se terminent par un rebord 25c en direction d'un bord du fossé BF adjacent . Cette plaque 25 est prolongée par une plaque de lissage 26 des couches de béton et ayant la même section trapézoïdale que la plaque de compression 25 . Le système d'épandage 4 précédemment décrit repose sur un châssis 1b sensiblement horizontal supporté par la chenille 3 . Ce châssis 1b , figure 4, supporte un étrier 30 monté pivotant autour d'un axe horizontal 31 perpendiculaire à l'axe longitudinal de la machine 1 . Cet étrier 30 se prolonge par une tige verticale 32 sur laquelle vient se fixer , par des attaches symbolisées en 33, la surface d'extrémité avant de la trémie 10 pour assurer la traction du système d'épandage par la chenille 3.The compression and smoothing system 5, FIGS. 1 and 5, is formed by a plate 25 of trapezoidal section slightly inclined from the front towards the rear. This plate 25 is fixed, by one end or front end, to the base of the rear wall 14 of the formwork 11. The distance separating the rear edge of this plate 25 from the ditch F fixes the thicknesses of the concrete layers on the bottom FF and on the lateral edges BF of the ditch F. The plate 25 comprises a central part 25 a facing the bottom FF of the ditch and two inclined lateral parts 25 b parallel to the edges BF of the ditch F. The inclined parts 25 b end in a flange 25 c towards an edge of the adjacent BF ditch. This plate 25 is extended by a smoothing plate 26 for the layers of concrete and having the same trapezoidal section as the compression plate 25. The previously described spreading system 4 rests on a substantially horizontal chassis 1b supported by the track 3. This chassis 1b , FIG. 4, supports a stirrup 30 mounted to pivot about a horizontal axis 31 perpendicular to the longitudinal axis of the machine 1. This stirrup 30 is extended by a vertical rod 32 on which is fixed, by fasteners symbolized at 33, the front end surface of the hopper 10 to ensure the traction of the spreading system by the track 3.

La structure de la machine 1 est complétée par des dispositifs de réglage , d'une part , de l'épaisseur des couches de béton et, d'autre part, pour la stabilité du système d'épandage .The structure of the machine 1 is completed by adjustment devices, on the one hand, for the thickness of the concrete layers and, on the other hand, for the stability of the spreading system.

En référence aux figures 2 et 4, le dispositif de réglage 40 de l'épaisseur des couches de béton est constitue, dans l'exemple considéré ici, par deux lames 41, 42 en regard l'une de l'autre et respectivement supportées par le châssis 1b et la base de la trémie 10. Ces lames s'étendent perpendiculairement à l'axe longitudinal de la machine 1 et sont situées vers la partie arrière de la chenille 3. Des vis 43, situées vers les deux extrémités de ces lames 41,42 traversent une lame pour prendre appui sur l'autre lame afin de les écarter l'une de l'autre, en entraînant un mouvement pivotant du système d'épandage 4 vers l'avant autour de l'axe de rotation 31 situé à l'avant de la chenille 3 . Lorsque les lames 41, 42 sont en appui l'une sur l'autre, la hauteur h définissant l'épaisseur de la couche déposée sur le fond FF du fossé F et la distance d définissant l'épaisseur des couches de béton sur les bords BF du fossé F, sont minimales. Tout écartement entre les lames 41, 42 entraine donc une augmentation de la hauteur h et de la distance d . D'une manière générale, ce dispositif de réglage ne joue que sur quelques centimètres.With reference to FIGS. 2 and 4, the device 40 for adjusting the thickness of the concrete layers is, in the example considered here, made up of two blades 41, 42 facing each other and respectively supported by the chassis 1b and the base of the hopper 10. These blades extend perpendicular to the longitudinal axis of the machine 1 and are located towards the rear part of the track 3. Screws 43, located towards the two ends of these blades 41,42 pass through a blade to rest on the other blade in order to separate them from each other, causing a pivoting movement of the spreading system 4 forwards around the axis of rotation 31 located at the front of the track 3. When the blades 41, 42 are supported one on the other, the height h defining the thickness of the layer deposited on the bottom FF of the ditch F and the distance d defining the thickness of the layers of concrete on the edges BF of ditch F, are minimal. Any spacing between the blades 41, 42 therefore causes an increase in the height h and the distance d . Generally, this adjustment device only plays on a few centimeters.

En référence à nouveau à la figure 1, le dispositif de reglage de la stabilité du système d'épandage 4 comprend deux patins latéraux retractables 51 disposés de part et d'autre de la chenille 3, vers l'arrière de celle-ci. Chaque patin 51 est articulé a l'extrémité d'une biellette 51a dont l'autre extrémité est articulée au châssis 1b, et est commandé en déplacement au moyen d'un vérin 52 monté en position inclinee de manière à venir appliquer temporairement le patin 51 associé sur le bord BF adjacent du fossé F. Les vérins 52 sont commandés séparement à partir du poste de pilotage 6 et alimentés à partir de la pompe P1.Referring again to FIG. 1, the device for adjusting the stability of the spreading system 4 comprises two retractable lateral pads 51 arranged on either side of the track 3, towards the rear of the latter. Each shoe 51 is articulated at the end of a link 51 a , the other end of which is articulated to the chassis 1 b , and is controlled to move by means of a jack 52 mounted in an inclined position so as to temporarily apply the pad 51 associated on the adjacent edge BF of the ditch F. The jacks 52 are ordered separately from cockpit 6 and supplied from pump P1.

Lorsque l'un des patins 51 vient en appui sur le bord adjacent BF du fosse F, l'ensemble du système d'épandage 4 peut pivoter autour de l'axe longitudinal de la machine 1, grâce au jeu qui est prévu au niveau de son ancrage avec la tige 32 solidaire du châssis 1b porté par la chenille 3 (figure 4).When one of the pads 51 comes to bear on the adjacent edge BF of the pit F, the entire spreading system 4 can pivot around the longitudinal axis of the machine 1, thanks to the clearance which is provided at its anchoring with the rod 32 secured to the frame 1b carried by the track 3 (Figure 4).

En référence aux figures 1 et 5, le poste de pilotage 6 comprend un ensemble de manettes 60 (figure 1 ), notamment celles pour commander les moeurs M1 d'entrainement de la chenille 3 et M2 de rotation de la vis sans fin 20, les vérins 8 de déplacement des patins de direction 7, et les vérins 52 de déplacement des patins de stabilite 51. La personne chargée d'actionner ces différentes commandes monte sur un socle horizontal 61 fixé sur le dessus de la plaque de compression 25 par exemple (figure 5 ). Un socle auxiliaire horizontal 62, en contre-bas du socle 61, est fixé sur le dessus de la plaque de lissage 26 pour permettre à une seconde personne de surveiller les opérations et de parfaire éventuellement avec un outil manuel les imperfections du lissage des couches de béton.With reference to FIGS. 1 and 5, the cockpit 6 comprises a set of levers 60 (FIG. 1), in particular those for controlling the mores of drive of the track 3 and M2 of rotation of the worm 20, the cylinders 8 for moving the steering pads 7, and the cylinders 52 for moving the stability pads 51. The person responsible for actuating these various controls mounts on a horizontal base 61 fixed to the top of the compression plate 25 for example ( figure 5). A horizontal auxiliary base 62, below the base 61, is fixed on the top of the smoothing plate 26 to allow a second person to monitor the operations and possibly perfect with a manual tool the imperfections of the smoothing of the layers of concrete.

Le fonctionnement de la machine 1 precédemment décrite découle facilement de la structure de cette machine. La machine 1 se déplace par sa chenille 3 sur le fond FF du fossé F. Le beton préalablement déversé et stocké dans la trémie 10 est entraîné par la vis sans fin 20 à l'intérieur du coffrage 11. Le béton tombe directement par gravité par l'ouverture inférieure centrale 12 sur le fond FF du fossé F. Les ailettes 22, entraînées en rotation par la vis sans fin 20, brassent le béton et l'éjectent par les ouvertures latérales 15 sur les bords BF du fossé F. Le béton ainsi déposé selon une épaisseur grossière à la sortie du coffrage 11 est ramené à une épaisseur voisine de h dans le fond FF du fossé F et à une épaisseur voisine de d sur les bords BF, au fur et à mesure de l'avance de la machine 1, par l'intermédiaire de la paroi arrière 14 du coffrage 11. En effet, cette paroi 14 forme une butée qui limite le dépôt du béton dans l'espace situé entre le fossé F et la plaque de compression 25 . Après le passage de cette plaque 25 légerement inclinee , les epaisseurs des couches b1 , b2 ( figure 5 ) correspondent aux valeurs définies par h et d, celles-ci étant généralement sensiblement égales.The operation of the machine 1 previously described easily follows from the structure of this machine. The machine 1 moves by its track 3 on the bottom FF of the ditch F. The concrete previously spilled and stored in the hopper 10 is driven by the worm screw 20 inside the formwork 11. The concrete falls directly by gravity by the central lower opening 12 on the bottom FF of the ditch F. The fins 22, driven in rotation by the worm 20, stir the concrete and eject it through the lateral openings 15 on the edges BF of the ditch F. The concrete thus deposited in a coarse thickness at the outlet of the formwork 11 is reduced to a thickness close to h in the bottom FF of the ditch F and to a thickness close to d on the edges BF, as the machine 1 advances, by means of the rear wall 14 of the formwork 11. In fact, this wall 14 forms a stop which limits the deposition of the concrete in the space between ditch F and the compression plate 25. After the passage of this slightly inclined plate 25, the thicknesses of the layers b 1, b 2 (FIG. 5) correspond to the values defined by h and d , these being generally substantially equal.

Lorsque le fossé F fait une courbe, le patin de direction 7, situe à l'extérieur du rayon de courbure, est commandé en déplacement pour venir prendre appui sur le bord BF adjacent pour modifier en conséquence la direction de la chenille 3. Le temps pendant lequel le patin 7 vient en appui sur le bord BF du fosse dépend du rayon de courbure du fossé F et de la vitesse d'avance de la machine 1. Parallèlement, les patins de stabilite 51 viennent ou non en appui sur les bords adjacents BF du fossé F suivant le profil du fond FF du fossé F, afin de maintenir le système d'épandage sensiblement dans l'axe du fossé F et d'obtenir des épaisseurs de couches de béton sensiblement constantes.When the ditch F makes a curve, the steering shoe 7, located outside the radius of curvature, is controlled in movement to come to bear on the adjacent edge BF to modify the direction of the track 3 accordingly. during which the pad 7 comes to bear on the edge BF of the pit depends on the radius of curvature of the ditch F and on the speed of advance of the machine 1. At the same time, the stability pads 51 come or not to bear on the adjacent edges BF of the ditch F along the profile of the bottom FF of the ditch F, in order to maintain the spreading system substantially in the axis of the ditch F and to obtain substantially constant thicknesses of concrete layers.

La machine telle que décrite peut bien évidemment être utilisée pour bétonner des canaux d'irrigation, c'est-à-dire que son champ d'application n'est pas limitée aux seuls fossés bordant les routes ou autoroutes .The machine as described can obviously be used for concreting irrigation canals, that is to say that its field of application is not limited to only ditches bordering roads or motorways.

Bien entendu, les éléments constitutifs de la machine décrits à titre d'exemple peuvent être remplacés par des moyens équivalents à la portée de l'homme de métier. En particulier, le système de déplacement 3 peut être constitué par deux chenilles articulées et directrices, montées l'une derrière l'autre, ce qui permet de supprimer les patins de direction 7. Le système d'épandage peut être complété par deux vis sans fin complémentaires, logées à l'intérieur du coffrage 11, et qui permettent de remonter le béton pour que celui-ci soit déposé en quantité suffisante sur les bords BF du fossé F, notamment lorsque ces bords doivent être bétonnés sur une hauteur importante. Les vis 43 qui servent au réglage de l'épaisseur des couches de béton, peuvent être remplacées par des vérins hydrauliques. Un treillis métallique formant armature peut être préalablement déroulé sur le fond et sur les bords du fossé F, puis noye dans les couches de béton déposées par la machine pour réaliser des fossés en béton armé. Enfin, une telle machine peut être également télécommandée ou téléguidée à distance, selon des techniques connues déjà utilisées pour les engins de travaux publics.Of course, the components of the machine described by way of example can be replaced by means equivalent to the scope of the skilled person. In particular, the displacement system 3 can be constituted by two articulated and guiding tracks, mounted one behind the other, which makes it possible to remove the steering shoes 7. The spreading system can be completed by two screws without additional end, housed inside the formwork 11, and which allow the concrete to be raised so that it is deposited in sufficient quantity on the edges BF of the ditch F, especially when these edges must be concreted over a significant height. The screws 43 which are used to adjust the thickness of the concrete layers, can be replaced by hydraulic cylinders. A wire mesh forming a reinforcement can be previously unrolled on the bottom and on the edges of the ditch F, then embedded in the concrete layers deposited by the machine to make reinforced concrete ditches. Finally, such a machine can also be remotely controlled or remotely controlled, according to known techniques already used for public works vehicles.
