Description
La présente invention concerne un appareil à châssis télescopique pour creuser des tranchées verticales dans le sol.The present invention relates to an apparatus with a telescopic frame for dig vertical trenches in the ground.
On connaít déjà des appareils pour creuser des tranchées verticales dans le sol, du type constitué par un châssis à la partie inférieure duquel deux paires de tambours de fraisage sont entraínées en rotation pour désagréger le sol à mesure que l'appareil s'y enfonce.We already know devices for digging vertical trenches in the ground, of the type consisting of a frame at the bottom of which two pairs of milling drums are rotated to break up the soil to as the device sinks into it.
Un tel appareil est suspendu au mât d'un engin de levage et progresse verticalement dans le sol sous l'effet de son propre poids. Un tel appareil est connu de EP-A-0 518 298.Such a device is suspended from the mast of a lifting device and progresses vertically in the ground under the effect of its own weight. Such an apparatus is known from EP-A-0 518 298.
Dans certains terrains meubles, il est quelquefois nécessaire de soulager les tambours de fraisage d'une partie du poids de l'appareil, afin de limiter la vitesse de progression de l'appareil et respecter ainsi le débit des moyens qui sont prévus dans le châssis pour évacuer les déblais jusqu'à la surface du sol.In some soft ground, it is sometimes necessary to relieve the milling drums of part of the weight of the device, in order to limit the speed of progression of the device and thus respect the flow of the means which are provided in the chassis to evacuate the cuttings to the ground surface.
Dans des terrains plus durs, on relâche au contraire l'appareil qui appuie alors de tout son poids sur les tambours de fraisage.On harder ground, on the contrary, the device is released. then presses with all its weight on the milling drums.
Cet appareil connu donne satisfaction dans la plupart des sols.This known device is satisfactory in most soils.
Toutefois, dans des terrains très durs tels que les roches, il peut s'avérer que le poids de l'appareil soit insuffisant pour exercer sur les tambours de fraisage une force leur permettant de désagréger le terrain.However, in very hard terrain such as rocks, it can be that the weight of the device is insufficient to exert on the milling drums a force allowing them to disintegrate the terrain.
La présente invention vise à résoudre ce problème en proposant un dispositif simple et économique à réaliser.The present invention aims to solve this problem by proposing a simple and economical device to make.
La présente invention a pour objet un appareil pour creuser des
tranchées verticales dans
un sol comportant des terrains très durs, tel que defini par
la revendication 1.The present invention relates to an apparatus for digging
vertical trenches in
soil with very hard soil, as defined by
De préférence, l'appareil selon l'invention comporte également des moyens de positionnement permettant de l'orienter par rapport à la tranchée.Preferably, the apparatus according to the invention also comprises positioning means for orienting it relative to the trench.
Lorsqu'on réalise une tranchée verticale avec l'appareil selon l'invention, on peut, si l'on rencontre une couche rocheuse, éventuellement orienter l'appareil convenablement pour corriger un défaut de verticalité, l'ancrer dans la tranchée et exercer une poussée dirigée vers le bas sur les tambours de fraisage pour accroítre la force d'appui de ces derniers sur le terrain.When making a vertical trench with the device according to the invention, one can, if one encounters a rocky layer, possibly orient the device suitably to correct a defect in verticality, anchor it in the trench and push down on the milling drums to increase the support force of the latter on the ground.
Le châssis se compose d'une partie porte-outil qui supporte les tambours de fraisage et leur moteur d'entraínement, et d'une partie d'ancrage qui supporte les moyens d'ancrage et éventuellement les moyens de positionnement, les moyens télescopiques reliant la partie porte-outil à la partie d'ancrage du châssis.The chassis is consists of a tool holder part which supports the milling drums and their drive motor, and an anchoring part which supports the anchoring means and possibly the positioning means, the telescopic means connecting the tool holder part to the chassis anchoring part.
La partie porte-outil s'engage dans un logement de la partie d'ancrage, et peut y coulisser axialement.The tool holder part engages in a housing of the anchoring part, and can slide there axially.
L'appareil selon l'invention peut être utilisé non seulement pour vaincre la résistance de terrains très durs, mais également pour rectifier un défaut de verticalité de la tranchée lorsque l'appareil dévie de sa trajectoire, par exemple si les tambours de fraisage travaillent à cheval sur deux couches de terrain de natures différentes.The apparatus according to the invention can be used not only for overcoming the resistance of very hard terrains, but also to rectify a defect verticality of the trench when the device deviates from its path, for example if the milling drums work astride two layers of terrain different natures.
En effet, dans un tel cas, on peut faire progresser l'appareil par extensions successives des moyens télescopiques, en utilisant uniquement la force d'appui de ces derniers, ce qui oblige les tambours de fraisage à progresser rigoureusement dans l'axe de l'appareil et donc dans le prolongement de la tranchée verticale déjà réalisée.Indeed, in such a case, the apparatus can be advanced by successive extensions of the telescopic means, using only force the latter, which forces the milling drums to progress rigorously in the axis of the device and therefore in the extension of the trench vertical already done.
Dans certains cas, il peut aussi être utile d'utiliser l'appareil selon l'invention pour soulager les tambours de fraisage d'une partie du poids de l'appareil, en ancrant ce dernier dans la tranchée et en exerçant sur les tambours de fraisage une force inférieure au poids de l'appareil.In some cases, it may also be useful to use the device depending on the invention to relieve the milling drums of part of the weight of the device, anchoring it in the trench and exercising on the drums milling a force less than the weight of the device.
Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant un mode de réalisation donné à titre d'exemple non limitatif en référence au dessin annexé dans lequel :
- la figure 1 est une vue en élévation d'un appareil selon un mode de réalisation de l'invention , et
- la figure 2 est une vue en coupe partielle de l'appareil de la figure 1, en cours d'utilisation pour réaliser une tranchée.
- FIG. 1 is an elevation view of an apparatus according to an embodiment of the invention, and
- Figure 2 is a partial sectional view of the apparatus of Figure 1, in use for making a trench.
L'appareil représenté sur la figure 1 comprend un châssis 1 qui est
muni à sa partie inférieure de deux paires de tambours de fraisage 2 dont on ne voit
qu'un tambour sur la figure 1, le tambour caché de chaque paire étant situé sur le
même axe que le tambour visible, et derrière celui-ci.The apparatus shown in Figure 1 comprises a
Chaque paire de tambours est entraínée en rotation dans la direction
indiquée par la flèche 3, grâce à un moteur (non représenté).Each pair of drums is rotated in the direction
indicated by
Les deux paires de tambours tournent autour d'axes distincts parallèles entre eux et orthogonaux à l'axe longitudinal de l'appareil de forage, c'est-à-dire autour d'axes horizontaux en position de travail. Les axes de rotation sont tous les deux disposés sensiblement dans un même plan orthogonal à l'axe longitudinal de l'appareil.The two pairs of drums rotate around separate parallel axes between them and orthogonal to the longitudinal axis of the drilling rig, i.e. around horizontal axes in working position. The axes of rotation are all two arranged substantially in the same plane orthogonal to the longitudinal axis of the device.
Au cours de la rotation, les tambours de fraisage désagrègent le terrain
situé en dessous de l'appareil et les déblais en résultant sont aspirés par une bouche
d'aspiration 4, reliée à une pompe 5, qui refoule les déblais jusqu'à la surface du sol
au travers d'un flexible de boue 6. La bouche d'aspiration 4 est disposée entre les
deux paires de tambours.During the rotation, the milling drums break up the ground
located below the device and the resulting cuttings are sucked in through a
Le châssis 1 est suspendu à son extrémité supérieure par un moufle 7 à
un engin de levage (non représenté) d'où proviennent des flexibles hydrauliques 8
qui fournissent l'énergie hydraulique nécessaire au fonctionnement du moteur des
tambours 2, de la pompe 5 et des autres organes de l'appareil.The
Le châssis 1 se compose de deux parties :
Il comporte, d'une part, une partie porte-outil 1a sur laquelle sont
montés les tambours de fraisage 2, leur moteur d'entraínement et la pompe de
refoulement des déblais 5.It comprises, firstly, a holder portion has
D'autre part, le châssis comporte une partie d'ancrage 1b rigide et non
déformable qui est munie à sa partie inférieure d'un logement 9 débouchant vers le
bas, et dans lequel la partie porte-outil 1a peut s'engager pour y coulisser
axialement.On the other hand, the chassis comprises an anchoring
Des vérins hydrauliques 10, assujettis d'une part à la partie porte-outil
1a et d'autre part à la partie d'ancrage 1b, permettent de faire coulisser
axialement la partie porte-outil 1a dans le logement 9 en étant guidée par des
glissières (non représentées). Les glissières permettent d'assujettir la partie porte-outil
1a à ne se déplacer que selon la direction longitudinale du châssis, c'est-à-dire
de la partie d'ancrage 1b. Cette direction est la direction verticale lorsque
l'appareil est en position de travail.
Comme on le voit sur la figure 1, à l'état rentré de la partie porte-outil
1a, les dimensions extérieures du châssis 1 se limitent à celles de la partie
d'ancrage 1b qui se présente ici sous la forme d'un parallélépipède rectangle d'une
hauteur d'environ 8 mètres.As can be seen in FIG. 1, in the retracted state of the tool-carrying
A l'état sorti de la partie porte-outil 1a, comme représenté à la figure 2,
c'est-à-dire lorsque la partie porte-outil 1a a coulissé vers le bas pour dépasser en
dessous de la partie d'ancrage 1b, le châssis s'allonge d'une hauteur correspondant à
la course des vérins hydrauliques 10, soit environ un mètre.At state out of the
La partie d'ancrage 1b est munie d'une pluralité de patins de
positionnement 11 qui permettent de guider l'appareil lors de sa descente dans la
tranchée, comme on le voit sur la figure 2. Un mode particulier de réalisation de
tels patins est notamment décrit dans la demande de brevet européen 593 355
déposée au nom de la demanderesse. De préférence, on trouve une série de patins
supérieurs et une série de patins inférieurs.The anchoring
En particulier, si l'appareil se met à dévier de sa trajectoire verticale, on
corrige son orientation en agissant sur certains patins 11 de manière à orienter le
châssis dans une direction opposée à la déviation.In particular, if the device starts to deviate from its vertical trajectory, we
corrects its orientation by acting on
En outre, conformément à l'invention, les patins de positionnement 11
permettent de positionner convenablement le châssis immobilisé dans la tranchée,
pour l'ancrer dans cette tranchée.Furthermore, in accordance with the invention, the
A cet effet, la partie d'ancrage 1b est également munie de deux patins
d'ancrage 12 sur ses deux grandes faces. Ces patins d'ancrage s'écartent du châssis
pour venir prendre appui sur les parois de la tranchée une fois le positionnement
correct de l'appareil réalisé grâce aux patins de positionnement 11. Les patins 12
sont de préférence commandés par des vérins hydrauliques.To this end, the anchoring
Il faut ajouter que les vérins hydrauliques 10 sont alimentés par des
circuits hydrauliques de commande qui permettent de contrôler la poussée exercée
pour le porte-outil 1a lorsque la partie d'ancrage 1b est rendue solidaire de la
tranchée à l'aide des patins d'ancrage 12. On peut ainsi adapter la poussée exercée
sur le porte-outil 1a et donc sur les fraises à la dureté du sol à forer.It should be added that the
Dans son utilisation courante, l'appareil est utilisé avec la partie porte-outil la du châssis en position rentrée.In everyday use, the device is used with the tool holder part the chassis in the retracted position.
Si, au cours du forage, les tambours de fraisage 2 rencontrent une
couche de terrain très dure qu'ils ne parviennent pas à désagréger, on positionne
d'une manière précise la partie d'ancrage 1b grâce aux patins 11 et l'on sort les
patins d'ancrage 12 de manière à immobiliser cette partie d'ancrage par rapport à la
tranchée.If, during drilling, the
On agit ensuite sur les vérins 10 pour exercer une poussée sur la partie
porte-outil 1a, et par conséquent sur les tambours de fraisage, de manière à leur
imprimer une force d'appui sur le terrain supérieure à celle qui résulterait du seul
poids de l'appareil.Then acts on the
Les tambours de fraisage et la partie porte-outil peuvent alors s'enfoncer dans la couche de terrain dur, sur toute la course des vérins hydrauliques 10.The milling drums and the tool holder can then sink into the hard ground layer, over the entire stroke of the cylinders hydraulic 10.
On rentre ensuite les patins d'ancrage 12 pour libérer la partie
d'ancrage 1b et on laisse descendre cette partie d'ancrage 1b dans la tranchée
verticale pour qu'elle vienne coiffer la partie porte-outil 1a sous l'effet de son
propre poids, en contrôlant cette descente à l'aide des vérins hydrauliques 10.The anchor portion is then returned to the
La partie porte-outil 1a reprend ainsi sa position rentrée.The
S'il subsiste une couche de terrain dur sous les tambours de fraisage, on répète les opérations qui viennent d'être décrites.If there is a layer of hard ground under the milling drums, repeat the operations which have just been described.
Dans le cas contraire, on poursuit la réalisation de la tranchée de façon traditionnelle, c'est-à-dire en conservant la partie porte-outil en position rentrée et en laissant les tambours de fraisage travailler sous la seule action du poids de l'appareil.Otherwise, the construction of the trench is continued so traditional, i.e. by keeping the tool holder part in the retracted position and leaving the milling drums to work under the sole action of the weight of the device.
Il est bien entendu que le mode de réalisation qui vient d'être décrit ne présente aucun caractère limitatif, et qu'il pourra recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention telle que définie par les revendications qui suivent.It is understood that the embodiment which has just been described does not is in no way limiting, and that it may receive any modifications desirable without departing from the scope of the invention as defined by the following claims.
