Description

L'invention se rapporte à un dispositif de forage de sol, plus particulièrement mais non exclusivement, en vue de la pose de canalisations.The invention relates to a soil drilling device, more particularly but not exclusively, with a view to laying pipes.

Un procédé connu de pose des canalisations consiste à creuser une fosse de départ et une fosse d'arrivée jusqu'à une profondeur légèrement supérieure à celle de la canalisation et à descendre dans la fosse de départ, un dispositif qui, à l'aide d'un outil approprié effectuera un forage horizontal jusqu'à la fosse d'arrivée par engagement à force de cet outil sous la poussée qu'au moins un vérin exerce sur un élément longiligne intermédiaire, généralement tubulaire constitué de plusieurs tronçons placés un à un dans un berceau de guidage associé au vérin pour étre relié aux précédents tronçons et participer avec eux à la progression de l'outil.A known method of laying pipes consists of digging a starting pit and an ending pit to a depth slightly greater than that of the pipe and descending into the starting pit, a device which, using '' a suitable tool will carry out a horizontal drilling until the arrival pit by force engagement of this tool under the push that at least one jack exerts on an elongated intermediate element, generally tubular made up of several sections placed one by one in a guide cradle associated with the jack to be connected to the previous sections and participate with them in the progression of the tool.

Cette technique donne de bons résultats car il évite de creuser des tranchées avec des inconvénients inhérents à cette technique (destruction du revêtement et de la structure du terrain, perturbation du trafic routier ...).This technique gives good results because it avoids digging trenches with drawbacks inherent in this technique (destruction of the surface and the structure of the ground, disruption of road traffic ...).

Cependant, vu l'encombrement de ces dispositifs qui, pour être convenablement placés à l'intérieur de la fosse de départ, requièrent de la part de celle-ci des caractéristiques dimensionnelles importantes, on déplore que les dispositifs de forage connus à ce jour conduisent inévitablement à des travaux de terrassement considérables.However, given the size of these devices which, to be properly placed inside the starting pit, require significant dimensional characteristics from the latter, it is regrettable that the drilling devices known to date lead inevitably to considerable earthworks.

Afin de limiter au moins partiellement cet inconvénient, il est connu (FR-2.527.679) un dispositif de forage constitué d'un bâti sur lequel, via des organes de réglage azimutal, sont fixés deux vérins parallèles dont les extrémités respectives des tiges de piston sont reliées entre elles par le biais d'un organe de liaison de guidage associé au berceau qui est quant à lui disposé entre les dits vérins où il reçoit les tronçons de l'élément intermédiaire permettant la progression de l'outil de forage.In order to at least partially limit this drawback, it is known (FR-2,527,679) a drilling device consisting of a frame on which, via azimuthal adjustment members, are fixed two parallel cylinders whose respective ends of the rods piston are connected to each other by means of a guide connecting member associated with the cradle which is itself disposed between said cylinders where it receives the sections of the intermediate element allowing the progression of the drilling tool.

Selon cette conception particulière, avec ce berceau de guidage placé entre les vérins, il apparaît clairement que, tout au moins longitudinalement, un tel dispositif bénéficie d'un encombrement réduit au maximum.According to this particular design, with this guide cradle placed between the jacks, it clearly appears that, at least longitudinally, such a device benefits from a space requirement reduced to the maximum.

En effet, en position rétractée, un tel dispositif présente l'avantage de permettre la mise en place des tronçons de l'élément intermédiaire par le dessus du dit dispositif sans nécessiter en avant du vérin de place autre que celle nécessaire au débattement du vérin.In fact, in the retracted position, such a device has the advantage of allowing the sections of the intermediate element to be put in place from above said device without requiring the place cylinder in front other than that necessary for the movement of the cylinder.

Cependant, il est à noter que, bien que donnant de bons résultats sur le plan de l'encombrement longitudinal, ce dispositif n'apporte pas de solution au plan de l'encombrement transversal et possède une cinématique assez complexe.However, it should be noted that, although giving good results in terms of longitudinal dimensions, this device does not provide a solution in terms of transverse dimensions and has quite complex kinematics.

En effet, pour conserver les paramètres de réglage azimutal définissant la direction selon laquelle s'effectue la poussée, les deux vérins doivent être synchronisés et donc alimentés au travers d'une régulation précise.In fact, to keep the azimuth adjustment parameters defining the direction in which the thrust takes place, the two jacks must be synchronized and therefore supplied through precise regulation.

Pour palier à cet inconvénient, il est connu (US-A-4.000.879) un dispositif ne comportant qu'un seul vérin au dessus duquel est placé le berceau de guidage.To overcome this drawback, it is known (US-A-4,000,879) a device comprising only a single cylinder above which is placed the guide cradle.

Dès lors, la progression correcte de l'outil de forage ne nécessite théoriquement aucune régulation de l'action du dit vérin, puisque celui-ci fixé au bâti du dispositif de forage est, par le biais du déplacement de la tige de son piston, seul responsable du mouvement de translation du berceau de guidage. Cependant, de l'écartement entre l'axe du vérin et celui de berceau guidant le tronçon de l'élément intermédiaire poussant l'outil résulte un couple engendrant des efforts antagonistes qui faussent la direction selon laquelle s'effectue la progression de l'outil.Consequently, the correct progression of the drilling tool theoretically does not require any regulation of the action of said jack, since the latter fixed to the frame of the drilling device is, by means of the displacement of the rod of its piston, solely responsible for the translational movement of the guide cradle. However, the spacing between the axis of the jack and that of the cradle guiding the section of the intermediate element pushing the tool results in a torque generating opposing forces which distort the direction in which the progression of the tool takes place. .

Un résultat que l'invention vise à obtenir est un dispositif de forage de conception compact, ne nécessitant pour sa mise en oeuvre que la réalisation d'une fosse de départ de dimensions très réduites.A result which the invention aims to obtain is a drilling device of compact design, requiring for its implementation only the production of a starting pit of very reduced dimensions.

Un autre résultat visé par l'invention est un dispositif de forage dont la cinématique des pièces en mouvement est suffisamment simple pour assurer au cours de la mise en oeuvre du dispositif, la fidélité du réglage d'orientation azimutale. A cet effet, l'invention a pour objet un dispositif de forage du type précité, notamment caractérisé en ce que le berceau de guidage du tronçon de l'élément intermédiaire est réalisé par un trou borgne intérieur la tige du piston et dont l'axe est confondu avec l'axe de la dite tige.Another result targeted by the invention is a drilling device, the kinematics of the moving parts is simple enough to ensure during the implementation of the device, the fidelity of the azimuthal orientation adjustment. To this end, the subject of the invention is a drilling device of the aforementioned type, in particular characterized in that the cradle for guiding the section of the intermediate element is produced by a blind hole inside the piston rod and whose axis is confused with the axis of said rod.

D'autres avantages et résultats appara'tront au cours de la description qui va suivre, faite à titre d'exemple non limitatif et qui représente schématiquement :

  • - figure 1 : le dispositif de forage vu de dessus,
  • - figure 2 : une coupe selon II-II de la figure 1.
Other advantages and results will appear during the description which follows, given by way of nonlimiting example and which schematically represents:
  • - Figure 1: the drilling device seen from above,
  • - Figure 2: a section along II-II of Figure 1.

En se reportant au dessin, on voit que, dans la fosse de départ 1 est descendu un dispositif de forage 2 comprenant un vérin 3 dont le cylindre 4 est, par le biais d'organes de réglage azimutal 5, 6, immobilisé dans un bâti 7 appuyé sur et/ou ancré à au moins un (8) des flancs de la fosse 1.Referring to the drawing, it can be seen that, in the starting pit 1, a drilling device 2 is lowered comprising a jack 3, the cylinder 4 of which, by means of azimuth adjustment members 5, 6, immobilized in a frame 7 pressed on and / or anchored to at least one (8) of the sides of the pit 1.

Tel que cela est connu, les différents paramètres de réglage propres à assurer la trajectoire de l'organe de forage selon un axe AAʹ, et, par conséquent, l'orientation du vérin 3 par rapport au bâti 7 sont déterminés en fonction de l'utilisation d'appareils de mesure propres au géomètre.As is known, the various adjustment parameters suitable for ensuring the trajectory of the drilling member along an axis AAʹ, and, consequently, the orientation of the jack 3 relative to the frame 7 are determined according to the use of measuring devices specific to the surveyor.

La progression de l'outil de forage 9 selon cet axe AAʹ est assurée par le biais du vérin 3 dont l'extrémité 10 de la tige 11 de son piston 12 est reliée à un berceau de guidage 13 apte à loger partiellement un tronçon d'un élément intermédiaire longiligne 14, tel un tube, lequel berceau de guidage 13 provoque par son déplacement selon un axe sensiblement concentrique l'axe AAʹ, la translation de l'élément intermédiaire 14 et par cela, la progression de l'outil de forage 9.The progression of the drilling tool 9 along this axis AAʹ is ensured by means of the jack 3, the end 10 of the rod 11 of its piston 12 is connected to a guide cradle 13 capable of partially housing a section of an elongate intermediate element 14, such as a tube, which guide cradle 13 causes, by its displacement along a substantially concentric axis, the axis AAʹ, the translation of the intermediate element 14 and by this, the progression of the drilling tool 9 .

Cependant, au lieu que l'élément le berceau de guidage se situe soit dans le prolongement du vérin 3 ce qui, dans ce cas, augmenterait considérablement l'encombrement du dispositif de forage 2, soit sur le côté ou au dessus de ce vérin, ce qui engendrerait un couple néfaste, selon l'invention, le berceau de guidage 13 est réalisé par un trou borgne 15 intérieur à la tige 11 du piston 12 et dont l'axe BBʹ est confondu avec l'axe CCʹ de la tige 11.However, instead of the element the guide cradle being situated in the extension of the jack 3 which, in this case, would considerably increase the size of the drilling device 2, either on the side or above this jack, which would generate a harmful torque, according to the invention, the guide cradle 13 is produced by a blind hole 15 inside the rod 11 of the piston 12 and the axis BBʹ of which coincides with the axis CCʹ of the rod 11.

Cette conception particulière du berceau 13 présente l'avantage de réaliser un dispositif de forage 2 qui se suffit de fosses dont les dimensions longitudinales transversales sont réduites au maximum.This particular design of the cradle 13 has the advantage of producing a drilling device 2 which suffices from pits whose transverse longitudinal dimensions are reduced to the maximum.

C'est, bien entendu, pour éviter lors de la mise en oeuvre du dispositif 12 que les efforts résultant de la poussée, via l'élément intermédiaire 14, contribuent à exercer sur le dispositif de forage 2 des contraintes qui, par leur action sur les organes de réglage 5, 6 soumettraient ceux-ci à une fatigue excessive et, en conséquence, le jeu de fonctionnement aidant, provoqueraient une altération des réglages initaux que, selon l'invention, les axes BBʹ, CCʹ respectifs du berceau de guidage 13 et de la tige 11 du piston 12 sont confondus et que, de ce fait, le berceau de guidage 13 et la tige 11 sont concentriques. Tel que cela apparaît sur le dessin, la conception particulière du berceau de guidage 13 permet de réaliser un dispositif de forage 2 nettement plus compact et, de ce fait, capable d'être placé à l'intérieur de la fosse de départ 1 dont les dimensions sont sensiblement proches de celles du vérin 3 en position rétractée.It is, of course, to avoid during the implementation of the device 12 that the forces resulting from the thrust, via the intermediate element 14, contribute to exerting on the drilling device 2 stresses which, by their action on the adjustment members 5, 6 subject them to excessive fatigue and, consequently, the operating clearance helping, would cause an alteration of the initial settings that, according to the invention, the respective axes BBʹ, CCʹ of the guide cradle 13 and the rod 11 of the piston 12 are combined and that, as a result, the guide cradle 13 and the rod 11 are concentric. As shown in the drawing, the particular design of the guide cradle 13 makes it possible to produce a drilling device 2 which is significantly more compact and, therefore, capable of being placed inside the starting pit 1, the dimensions are substantially close to those of the cylinder 3 in the retracted position.

Afin de rendre opérationnel le dispositif 2 tel que précédemment décrit, en créant par poussées successives la progression de l'outil de forage 3, il est bien évidemment nécessaire que le dispositif 2 ancré à l'intérieur de la fosse puisse recevoir facilement et cela sans manipulation excessive, les tronçons 14 de l'élément intermédiaire qui doit suivre celui venant d'étre poussé.In order to make the device 2 as described above operational, by creating successive pushes in the progression of the drilling tool 3, it is obviously necessary for the device 2 anchored inside the pit to be able to receive easily and without excessive handling, the sections 14 of the intermediate element which must follow that which has just been pushed.

A cet effet, pour permettre l'introduction d'au moins un tel tronçon 14 d'élément intermédiaire à l'intérieur du berceau de guidage 13 et pour assurer la fidélité des réglages établis lors de la mise en oeuvre du dispositif 2, le vérin 3 est articulé au bâti 7 autour d'un axe 16 horizontal, perpendiculaire et concourant à l'axe BBʹ du berceau 13 permettant de relever le vérin vers une position verticale.To this end, to allow the introduction of at least one such section 14 of intermediate element inside the guide cradle 13 and to ensure the fidelity of the adjustments established during the implementation of the device 2, the jack 3 is articulated to the frame 7 around a horizontal axis 16, perpendicular and contributing to the axis BBʹ of the cradle 13 for raising the cylinder to a vertical position.

Afin de libérer la manoeuvre, en position active le vérin ne repose sur son dispositif de réglage azimutal que par son simple poids.In order to release the maneuver, in the active position the jack rests on its azimuth adjustment device only by its simple weight.

Selon une forme avantageuse de réalisation, l'articulation du vérin 3 par rapport au bâti 7 est réalisée par une oreille 17 traversée par l'axe 16 d'une chape 19 de préférence fixée à une des faces 20 du batî 7 par le biais d'un organe de réglage 5. Ainsi donc, le dispositif de forage 2 permet la progression de l'outil de forage 9 et cela par poussées successives du vérin et interposition de tronçons supplémentaires d'élément intermédiaire 14.According to an advantageous embodiment, the articulation of the jack 3 relative to the frame 7 is produced by an ear 17 crossed by the axis 16 of a yoke 19 preferably fixed to one of the faces 20 of the frame 7 by means of an adjusting member 5. Thus, the drilling device 2 allows the drilling tool 9 to progress and this by successive thrusts of the jack and interposition of additional sections of intermediate element 14.

Pour ne pas entraver le rétablissement du vérin 3 dans sa position de travail, par exemple en butant contre une (21) des parois de la fosse de départ, la longueur des tronçons est sensiblement équivalente à la course du vérin.In order not to hinder the recovery of the jack 3 in its working position, for example by abutting against one (21) of the walls of the starting pit, the length of the sections is substantially equivalent to the stroke of the jack.

Cependant pour assurer une amplitude de translation du tronçon 14 de l'élément intermédiaire suffisante pour, au retour du vérin, dégager ce tronçon du vérin, le tronçon 14 ne pénètre dans le berceau de guidage 13 que sur une profondeur inférieure à la longueur de la course du piston.However, to ensure a sufficient amplitude of translation of the section 14 of the intermediate element to return this section of the cylinder to the return of the jack, the section 14 does not enter the guide cradle 13 except at a depth less than the length of the piston stroke.

Sous cette réserve, le fond 22 du trou borgne 15 peut avoisiner la tête 23 du piston 12.With this reservation, the bottom 22 of the blind hole 15 can be close to the head 23 of the piston 12.

Chaque tronçon ou au moins certains d'entre eux peuvent de plus, afin de limiter leur pénétration dans le berceau, présenter un moyen d'arrêt tel une excroissance locale ou une goupille amovible, appuyant contre l'extrémité de la tige du piston ou traversant un orifice qui serait prévu à cette extrémité, ne serait-ce que pour placer une telle goupille permettant de saisir un à un les tronçons en vue d'en permettre le retrait lorsque celui-ci est souhaité.Each section or at least some of them may furthermore, in order to limit their penetration into the cradle, present a stop means such as a local protrusion or a pin removable, pressing against the end of the piston rod or passing through an orifice which would be provided at this end, if only to place such a pin making it possible to grasp the sections one by one in order to allow their removal when this is desired.

Avec ce dispositif, on peut ne creuser qu'une fosse de longueur à peine supérieure à celle du vérin rétracté auquel cas, l'extrémité externe du vérin pénètre dans le sol.With this device, it is possible to dig only a pit of length barely greater than that of the retracted jack, in which case the external end of the jack penetrates into the ground.

A cet effet, son extrémité avant peut être chanfreinée.For this purpose, its front end can be chamfered.
