Description

APPAREIL DE FORATION ET DE BOULONNΑGE DESTINE Au CREUSEMENT ET Au SOUTENEMENT DE GALERIES L'invention concerne un appareil de foration et de boulonnage destiné au creusement et au soutènement de galeries. The invention relates to a drilling and bolting apparatus intended for digging and supporting galleries.
Pour réaliser une galerie, un tunnel ou similaire, il faut dans un premier temps creuser sur une certaine longueur dans la direction de la galerie puis, dans un second temps, soutenir la paroi de la galerie pour éviter qu'elle ne s'effondre, avant de poursuivre le creusement de la galerie. Pour mettre en oeuvre ces deux étapes, deux appareils distincts sont utilisées.To make a gallery, a tunnel or the like, you must first dig a certain length in the direction of the gallery and then, secondly, support the wall of the gallery to prevent it from collapsing, before continuing to dig the gallery. To implement these two steps, two separate devices are used.
Un premier appareil est destiné au creusement de la galerie. Il comporte une ou plusieurs glissières munies de têtes de forage agissant parallèlement à l'axe de la galerie. Chaque glissière est supportée par un bras articulé qui permet le positionnement de celle-ci dans la galerie.A first device is intended for digging the gallery. It comprises one or more slides provided with drilling heads acting parallel to the axis of the gallery. Each slide is supported by an articulated arm which allows its positioning in the gallery.
Le soutènement de la paroi est généralement réalisé par des boulons scellés dans la paroi à soutenir. Pour poser ces boulons, un trou est foré perpendiculairement à la paroi, un boulon est introduit dans le trou foré, y est scellé à l'aide par exemple d'un coulis de scellement, avant de recevoir enfin une tête d'ancrage.The wall support is generally carried out by bolts sealed in the wall to be supported. To install these bolts, a hole is drilled perpendicular to the wall, a bolt is introduced into the drilled hole, it is sealed there using for example a grout, before finally receiving an anchor head.
Une machine utilisée pour réaliser le soutènement comporte généralement une tourelle de foration et de boulonnage agissant perpendiculairement à l'axe de la galerie. Cette tourelle comprend une poutre servant de guide à un chariot de foration et à un chariot de boulonnage. La poutre est montée pivotante et coulissante à l'extrémité d'un bras support. L'ensemble est associé à un magasin de boulons dynamique.A machine used to carry out the support generally comprises a drilling and bolting turret acting perpendicular to the axis of the gallery. This turret comprises a beam serving as a guide for a drilling trolley and a bolting trolley. The beam is mounted to pivot and slide at the end of a support arm. The set is associated with a dynamic bolt store.
Les documents FR-1 359 297 et FR-2 520 800 décrivent une machine destinée à la foration et au boulonnage du type de celle décrite au paragraphe précédent.The documents FR-1 359 297 and FR-2 520 800 describe a machine intended for drilling and bolting of the type described in the previous paragraph.
Actuellement, deux machines distinctes sont nécessaires pour réaliser le creusement et le soutènement d'une galerie. L'utilisation de deux machines est un handicap d'un point de vue économique. D'une part ces machines sont d'un coût élevé et d'autre part il y a d'importantes pertes de temps lors de la mise en place de chacune de ces machines. Les appareils de foration et de boulonnage connus travaillent dans une direction de forage. Leur magasin de boulons dynamique ne permet pas l'utilisation de leur chariot de foration pour le creusement de la galerie. En effet, leur encombrement et leur complexité rendent cette utilisation impossible.Currently, two separate machines are needed to dig and support a gallery. The use of two machines is a handicap from an economic point of view. On the one hand these machines are of high cost and on the other hand there is significant loss of time during the installation of each of these machines. Known drilling and bolting apparatuses work in one direction of drilling. Their dynamic bolt store does not allow the use of their drilling trolley for digging the gallery. Indeed, their size and complexity make this use impossible.
L'invention a donc pour but de fournir un appareil de foration et de boulonnage destiné au creusement et au soutènement de galeries, évitant ainsi l'emploi de deux machines distinctes. A cet effet, l'invention propose un appareil de foration et de boulonnage de type comportant une poutre sur laquelle sont montés, d'une part un dispositif de boulonnage comportant un magasin pour des boulons et des moyens pour introduire ces derniers dans un trou foré et, d'autre part un dispositif de foration monté sur la poutre par l'intermédiaire d'une glissière de forage et comportant une perforatrice munie d'un outil de forage et des moyens de commande du coulissement de la glissière de forage sur la poutre, cette dernière étant montée à l'extrémité d'un bras articulé muni de moyens de commande.The invention therefore aims to provide a drilling and bolting apparatus for digging and supporting galleries, thus avoiding the use of two separate machines. To this end, the invention provides a drilling and bolting device of the type comprising a beam on which are mounted, on the one hand a bolting device comprising a magazine for bolts and means for introducing the latter into a drilled hole and, on the other hand, a drilling device mounted on the beam via a drilling slide and comprising a perforator provided with a drilling tool and means for controlling the sliding of the drilling slide on the beam. , the latter being mounted at the end of an articulated arm provided with control means.
Selon l'invention, la poutre est montée fixe sur l'extrémité du bras articulé, le magasin est monté coulissant par rapport à la poutre parallèlement à la direction de foration du dispositif de foration, et l'appareil de foration et de boulonnage comporte en outre des moyens pour repérer la position de l'outil de forage et un dispositif coopérant avec ces derniers moyens et avec les moyens de commande du bras articulé pour pouvoir amener un boulon placé dans le magasin en face d'un trou foré par l'outil de forage, la position relative de ce dernier et des compartiments du magasin étant mémorisée.According to the invention, the beam is fixedly mounted on the end of the articulated arm, the magazine is slidably mounted relative to the beam parallel to the drilling direction of the drilling device, and the drilling and bolting apparatus comprises in in addition to means for locating the position of the drilling tool and a device cooperating with the latter means and with the means for controlling the articulated arm so as to be able to bring a bolt placed in the magazine opposite a hole drilled by the drilling tool, the relative position of the latter and of the compartments of the store being memorized.
Dans cet appareil de foration et de boulonnage, le dispositif de foration peut aussi bien servir à la foration d'un trou pour y mettre un boulon qu'au creusement d'une galerie. La structure de cet appareil comporte un magasin statique pour les boulons qui ne gêne pas le dispositif de foration lorsque l'appareil est en position d'avancement dans une galerie ou un tunnel. Une telle structure permet la construction d'un appareil de foration et de boulonnage simple et peu encombrant et de ce fait adaptable sur un bras de forage d'une machine destinée au creusement de tunnels.In this drilling and bolting device, the drilling device can be used both for drilling a hole to put a bolt in it and for digging a gallery. The structure of this device has a static magazine for the bolts which does not interfere with the drilling device when the device is in the advancing position in a gallery or tunnel. Such a structure allows the construction of a simple and space-saving drilling and bolting device and therefore adaptable to a drilling arm of a machine intended for digging tunnels.
Lors de la pose d'un boulon avec cet appareil, le dispositif de foration fore de manière classique un trou destiné à recevoir un boulon. La position dans l'espace de l'outil de forage est repérée. De plus, la position relative de cet outil et des compartiments du magasin contenant les boulons est connue. Ainsi, grâce au dispositif coopérant avec les moyens de repérage de la position de l'outil de forage et avec les moyens de commande du bras articulé, ces derniers peuvent, une fois le trou foré, venir placer un compartiment du magasin contenant un boulon face au trou foré.When installing a bolt with this device, the drilling device conventionally drills a hole for receiving a bolt. The position in space of the drilling tool is marked. In addition, the relative position of this tool and the magazine compartments containing the bolts is known. Thus, thanks to the device cooperating with the means for locating the position of the drilling tool and with the means for controlling the articulated arm, the latter can, once the hole has been drilled, place a compartment of the magazine containing a facing bolt to the drilled hole.
Pour réduire l'encombrement de l'appareil, la poutre est avantageusement un profilé creux à l'intérieur duquel est monté coulissant le magasin.To reduce the size of the device, the beam is advantageously a hollow profile inside which the magazine is slidably mounted.
Pour rendre l'ensemble de l'appareil plus simple, l'invention propose de rendre le magasin solidaire de la glissière de forage.To make the whole of the apparatus simpler, the invention proposes to make the magazine integral with the drilling slide.
Toujours dans le but de rendre cet appareil le moins encombrant possible tout en étant aussi performant que possible, le magasin comporte avantageusement un tube d'injection de coulis de scellement.Always with the aim of making this device as compact as possible while being as efficient as possible, the store advantageously includes a grout injection tube.
Dans une forme d'exécution préférentielle, le magasin présente un ensemble de tubes parallèles qui sont tous fixés sur un même côté d'une plaque présentant une ouverture pour chaque tube, et le support du magasin est un support creux présentant une ouverture par tube dans laquelle le tube est guidé lorsque le magasin se déplace par rapport à la poutre. Dans cette forme d'exécution, l'invention propose de plus qu'en position de boulonnage, la plaque sur laquelle sont fixés les tubes du magasin soit disposée face à une seconde plaque munie d'ouvertures correspondant à celles de la première plaque mais de section plus petite, chaque ouverture de la seconde plaque faisant face à un tube du magasin logeant un boulon, étant munie d'un élément de guidage destiné à guider le boulon correspondant lors de son introduction dans un trou foré, que l'extrémité d'un boulon logé dans un tube du magasin, située à l'opposé des premières et secondes plaques soit engagée dans un evidement réalisé dans un piston étage, la section du piston du côté des plaques correspondant sensiblement à la section de l'ouverture correspondante de la seconde plaque et la section du piston à son autre extrémité correspondant à la section du tube dans lequel il se trouve, et que le tube, à son extrémité opposée aux plaques soit fermé par un obturateur raccordé à un circuit d'injection de fluide sous pression.In a preferred embodiment, the magazine has a set of parallel tubes which are all fixed on the same side of a plate having an opening for each tube, and the magazine support is a hollow support having an opening per tube in which the tube is guided when the magazine moves relative to the beam. In this embodiment, the invention further provides that in the bolting position, the plate on which the tubes of the magazine are fixed is disposed facing a second plate provided with openings corresponding to those of the first plate but of smaller section, each opening of the second plate facing a magazine tube housing a bolt, being provided with a guide element intended to guide the corresponding bolt during its introduction into a drilled hole, that the end of a bolt housed in a magazine tube, located opposite the first and second plates is engaged in a recess made in a stage piston, the section of the piston on the side of the plates corresponding substantially to the section of the corresponding opening of the second plate and the section of the piston at its other end corresponding to the section of the tube in which it is located, and that the tube, at its end opposite to the plates is closed by a shutter connected to a pressurized fluid injection circuit.
Avantageusement, le dipositif coopérant avec les moyens pour repérer la position de l'outil de forage (7) et avec les moyens de commande du bras articulé (25) est un calculateur. Cependant, il peut également s'agir d'un séquenceur hydraulique ou d'un automate.Advantageously, the device cooperating with the means for locating the position of the drilling tool (7) and with the control means of the articulated arm (25) is a computer. However, it can also be a hydraulic sequencer or an automaton.
De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé, représentant à titre d'exemple non limitatif un appareil de foration et de boulonnage selon l'invention.Anyway, the invention will be well understood with the aid of the description which follows, with reference to the appended schematic drawing, representing by way of example not limiting a drilling and bolting apparatus according to the invention.

The perforator 6 slides on the slide 5. The drilling tool 7 is mounted in the perforator 6 and is guided by the guide 8.
Le dispositif de foration 3 est de type connu et les différentes pièces qui le constituent ne seront pas décrites plus en détail ici. Le dispositif de boulonnage 4 comprend un support creux 9, un magasin 10 destiné à contenir des boulons 11 et des moyens pour pousser les boulons 11 hors du magasin vers un trou foré.The drilling device 3 is of known type and the various parts which constitute it will not be described in more detail here. The bolting device 4 comprises a hollow support 9, a magazine 10 intended to contain bolts 11 and means for pushing the bolts 11 out of the magazine towards a drilled hole.
Le support creux 9 est placé à l'intérieur de la poutre 2 et est solidaire de celle-ci, par soudage par exemple. Il sert de support et de palier au magasin 10. Le magasin 10 comporte une plaque d'extrémité 12 sensiblement rectangulaire et présentant sept ouvertures circulaires, ainsi que six tubes 13 identiques, destinés chacun à recevoir un boulon 11 et soudés chacun par l'une de leur extrémité au niveau d'une ouverture de la plaque 10. La septième ouverture reçoit de la même façon un tube 14 servant à une injection de coulis de scellement. La plaque d'extrémité 12 est fixée sur la glissière de forage 5, à proximité de l'une de ses extrémités, du même côté que la poutre 2. Tous les tubes 13,14 se situent du même côté de la plaque d'extrémité 12.The hollow support 9 is placed inside the beam 2 and is integral with the latter, for example by welding. It serves as support and bearing for store 10. The magazine 10 comprises a substantially rectangular end plate 12 and having seven circular openings, as well as six identical tubes 13, each intended to receive a bolt 11 and each welded by one of their ends at an opening of the plate 10. The seventh opening likewise receives a tube 14 used for injecting sealing grout. The end plate 12 is fixed to the drilling slide 5, near one of its ends, on the same side as the beam 2. All the tubes 13, 14 are located on the same side of the end plate 12.
Le support creux 9 présente un profil correspondant à celui de la plaque d'extrémité 12. Chaque tube 13,14 passe dans une ouverture circulaire de ce support 9. Les tubes 13,14 s'étendent ainsi parallèlement à la glissière de forage 5 et donc à la direction de forage du dispositif de foration 3.The hollow support 9 has a profile corresponding to that of the end plate 12. Each tube 13,14 passes through a circular opening of this support 9. The tubes 13,14 thus extend parallel to the drilling slide 5 and therefore to the drilling direction of the drilling device 3.
Une seconde plaque 16 fait face à la plaque d'extrémité 12. Ces deux plaques sont rendues solidaires par une goupille 17 clavetée (Fig.6). La seconde plaque 16 présente des ouvertures correspondant à celles de la plaque d'extrémité. Le diamètre des ouvertures correspondant à un tube 13 destiné à recevoir un boulon 11 est inférieur au diamètre intérieur du tube 13 correspondant, tout en étant supérieur au diamètre des boulons 11. Chacune de ces ouvertures reçoit un élément de guidage 18. Ce dernier présente un diamètre intérieur sensiblement égal au diamètre des boulons 11 et se fixe sur la seconde plaque 16, du côté opposé à la première plaque 12.A second plate 16 faces the end plate 12. These two plates are made integral by a pin 17 keyed (Fig.6). The second plate 16 has openings corresponding to those of the end plate. The diameter of the openings corresponding to a tube 13 intended to receive a bolt 11 is less than the internal diameter of the corresponding tube 13, while being greater than the diameter of the bolts 11. Each of these openings receives a guide element 18. The latter has a inner diameter substantially equal to the diameter of the bolts 11 and is fixed on the second plate 16, on the side opposite to the first plate 12.
A l'intérieur de chaque tube 13 se trouve un boulon 11. Une extrémité du boulon est engagée dans l'élément de guidage 18 monté sur la seconde plaque 16. L'autre extrémité est logé* dans un evidement 19 ménagé dans un piston 20. Ce dernier est destiné à coulisser dans le tube 13. Il comporte une zone 21 éloignée de la plaque d'extrémité 12 de diamètre sensiblement égal au diamètre intérieur du tube 13 et une zone 22 proche de la plaque d'extrémité 12 de diamètre sensiblement égal au diamètre des ouvertures de la seconde plaque 16. L'evidement 19 est un evidement cylindrique borgne parallèle à l'axe du boulon 11 et débouche du côté de la plaque d'extrémité 12.Inside each tube 13 is a bolt 11. One end of the bolt is engaged in the guide element 18 mounted on the second plate 16. The other end is housed * in a recess 19 formed in a piston 20 The latter is intended to slide in the tube 13. It has a zone 21 remote from the end plate 12 of diameter substantially equal to the inside diameter of the tube 13 and a zone 22 close to the end plate 12 of diameter substantially equal to the diameter of the openings of the second plate 16. The recess 19 is a blind cylindrical recess parallel to the axis of the bolt 11 and opens out on the side of the end plate 12.
Le tube 13, du côté opposé aux plaques 12,16 est fermé par un obturateur 23 amovible muni d'un raccord d'injection 24 de fluide sous pression.The tube 13, on the side opposite to the plates 12, 16 is closed by a removable shutter 23 provided with an injection connection 24 for pressurized fluid.
Le tube 14 d'injection de coulis de scellement est de type connu et n'est par décrit plus en détail ici.The sealing grout injection tube 14 is of known type and is not described in more detail here.
Comme le montrent les figures 3 à 5, l'appareil 1 décrit ci-dessus est monté à l'extrémité d'un bras articulé 25. Un vérin 26 est prévu pour pouvoir faire varier l'angle d'inclinaison entre l'extrémité du bras 25 et l'appareil de foration et de boulonnage 1. Ce bras articulé 25 présente au moins quatre degrés de liberté. Il est lui-même porté par un engin de creusement non représenté.As shown in Figures 3 to 5, the device 1 described above is mounted at the end of an articulated arm 25. A cylinder 26 is provided to be able to vary the angle of inclination between the end of the arm 25 and the drilling and bolting apparatus 1. This articulated arm 25 has at least four degrees of freedom. It is itself carried by a digging machine, not shown.
Le fonctionnement de l'appareil de foration et de boulonnage 1 décrit ci-dessus est le suivant.The operation of the drilling and bolting apparatus 1 described above is as follows.
La figure 3 montre cet appareil 1 en position d'avancement. Ce dernier est dans ce cas sensiblement parallèle à la galerie en cours de creusement, face à la paroi du fond 27 de cette galerie. La perforatrice 6 est en action pour abattre la paroi du fond. Durant cette phase d'avancement, le dispositif de boulonnage 4 est au repos. Le magasin statique 10 est vide et les tubes 13, 14 ne sont pas reliés à une source de fluide sous pression ou de coulis de scellement. Il ne gêne absolument pas le travail de foration de la perforatrice 6.Figure 3 shows this device 1 in the advancing position. The latter is in this case substantially parallel to the gallery during digging, facing the wall of the bottom 27 of this gallery. The perforator 6 is in action to tear down the bottom wall. During this advancement phase, the bolting device 4 is at rest. The static magazine 10 is empty and the tubes 13, 14 are not connected to a source of pressurized fluid or sealing grout. It absolutely does not interfere with the drilling work of the hole punch 6.
Au fur et à mesure de l'avancement de la galerie, pour éviter un effondrement de cette dernière, il faut régulièrement effectuer des opérations de soutènement. Ces opérations consistent à introduire des boulons d'ancrage dans la paroi latérale 28, et notamment la paroi supérieure, puis à fixer une plaque de soutènement sur ces boulons à l'aide d'une tête d'ancrage. Pour pouvoir mettre le boulon en place dans la paroi latérale 28, il faut tout d'abord réaliser un long trou 29 de faible diamètre, perpendiculairement à la paroi 28, puis y loger un boulon 11.As the gallery progresses, to avoid collapse of the latter, support operations must be carried out regularly. These operations consist in introducing anchor bolts in the side wall 28, and in particular the upper wall, then in fixing a support plate on these bolts using an anchoring head. To be able to put the bolt in place in the side wall 28, it is first necessary to make a long hole 29 of small diameter, perpendicular to the wall 28, then to house a bolt 11 there.
Les figures 4, respectivement 5, montrent l'appareil de foration et de boulonnage 1 en position de boulonnage, au cours du forage du trou 29 destiné à recevoir un boulon 11, respectivement au cours de la pose dans le trou foré 29 du boulon 11.Figures 4, respectively 5, show the drilling and bolting apparatus 1 in the bolting position, during the drilling of the hole 29 intended to receive a bolt 11, respectively during the installation in the drilled hole 29 of the bolt 11 .
Avant l'opération de boulonnage, le magasin 10 est chargé de boulons 11. Chacun de ceux-ci est placé dans un tube 13 et positionné dans un piston 20. L'extrémité correspondante du boulon 11 est logée dans 1 'evidement 19 du piston. Le tube 13 est alors fermé par un obturateur 23 et, une fois tous les obturateurs 23 en place, le dispositif de boulonnage 4 est raccordé à une source de fluide sous pression et à une source de coulis de scellement (non représentées) . La seconde plaque 16 est également équipée d'éléments de guidage 18.Before the bolting operation, the magazine 10 is loaded with bolts 11. Each of these is placed in a tube 13 and positioned in a piston 20. The corresponding end of the bolt 11 is housed in the recess 19 of the piston . The tube 13 is then closed by a shutter 23 and, once all the shutters 23 in place, the bolting device 4 is connected to a source of pressurized fluid and to a source of sealing grout (not shown). The second plate 16 is also equipped with guide elements 18.
Le bras articulé 25 est alors positionné de telle sorte que le dispositif de foration 3, et plus précisément la perforatrice 6, se trouve perpendiculaire à la paroi latérale 28 face à l'endroit souhaité pour mettre un boulon 11 (Figure 4) . La perforatrice 6 est mise en marche et avance le long de la glissière 5 comme le suggère la position dessinée en trait mixte sur la figure 4. Afin de connaître précisément la position du trou foré 29, des capteurs (non représentés) reliés à un calculateur (non représenté également) enregistrent les grandeurs angulaires et linéaires représentatives des paramètres de position du bras articulé 25. Une fois le trou 29 foré, l'outil de foration 7 est retiré. L'ensemble formé par la glissière 5 et le magasin 10 est reculé puis écarté de la paroi 28.The articulated arm 25 is then positioned so that the drilling device 3, and more precisely the perforator 6, is perpendicular to the side wall 28 facing the desired location for putting a bolt 11 (Figure 4). The perforator 6 is started and advances along the slide 5 as suggested by the position drawn in phantom in Figure 4. In order to know precisely the position of the drilled hole 29, sensors (not shown) connected to a computer (also not shown) record the angular and linear quantities representative of the position parameters of the articulated arm 25. Once the hole 29 has been drilled, the drilling tool 7 is removed. The assembly formed by the slide 5 and the magazine 10 is moved back then moved away from the wall 28.
L'étape suivante consiste à injecter du coulis de scellement dans le trou foré 29. Pour ce faire, le tube 14 d'injection de coulis de scellement est placé face au trou 29. Le positionnement relatif de la perforatrice 6, des tubes 13 du magasin 10, et du tube 14 d'injection de coulis de scellement est mémorisé dans une mémoire du calculateur. Un système de commande géré par le calculateur permet de positionner avec précision le bras articulé 25 de telle sorte que le tube 14 d'injection de coulis de scellement se retrouve face au trou 29 en alignement avec ce dernier, grâce aux paramètres stockés et enregistrés dans le calculateur. Le tube 14 est introduit dans le trou 29, puis retiré pour permettre la dépose de coulis de scellement le long du trou 29. Après retrait total du tube d'injection 14, l'ensemble formé par la glissière 5 et le magasin 10 est écarté de la paroi 28. Un boulon 11 peut maintenant être mis en place dans le trou 29. Les mouvements angulaires et linéaires du bras articulé 25 sont activés par le système de commande de manière à ce qu'un tube 13 contenant un boulon 11 se place face au trou foré 29 en alignement avec ce dernier. L'ensemble formé par la glissière 5 et le magasin 10 est avancé au contact de la paroi 28. Du fluide sous pression est injecté par le raccord 24 dans la chambre 30 délimitée par le piston 20, la paroi du tube 13 et l'obturateur 23. Ainsi le piston 20 correspondant pousse le boulon 11 vers le trou 29 (Figures 5 et 6) .The next step consists in injecting sealing grout into the drilled hole 29. To do this, the tube 14 for injecting sealing grout is placed facing the hole 29. The relative positioning of the hole punch 6, of the tubes 13 of the magazine 10, and of the sealing grout injection tube 14 is stored in a memory of the computer. A control system managed by the computer makes it possible to precisely position the articulated arm 25 so that the tube 14 for injecting sealing grout ends up facing the hole 29 in alignment with the latter, thanks to the parameters stored and recorded in the calculator. The tube 14 is introduced into the hole 29, then removed to allow the deposition of sealing grout along the hole 29. After total withdrawal of the injection tube 14, the assembly formed by the slide 5 and the magazine 10 is moved aside of the wall 28. A bolt 11 can now be placed in the hole 29. The angular and linear movements of the articulated arm 25 are activated by the control system so that a tube 13 containing a bolt 11 is placed facing the drilled hole 29 in alignment with the latter. The assembly formed by the slide 5 and the magazine 10 is advanced in contact with the wall 28. Fluid under pressure is injected by the connector 24 into the chamber 30 delimited by the piston 20, the wall of the tube 13 and the shutter 23. Thus the corresponding piston 20 pushes the bolt 11 towards the hole 29 (Figures 5 and 6).
Le boulon 11, poussé par le piston 20 et guidé par l'élément de guidage 18, pénètre dans le trou 29 contenant du coulis de scellement. En fin de course du piston 20, la zone 22 du piston de petit diamètre arrive au bout du tube 13, puis au niveau de l'ouverture de la seconde plaque 16. Comme indiqué plus haut, le diamètre de la zone 22 du piston est sensiblement égal au diamètre de l'ouverture de la plaque 16. Cette partie 22 du piston est telle qu'elle peut passer à travers cette ouverture. Un chanfrein 31 est prévu sur le piston pour faciliter son introduction à travers la seconde plaque 16. En s'introduisent à travers l'ouverture, le piston 20 vient chasser l'élément de guidage 18 et l'enfonce dans le trou 29. Le piston 20 est arrêté lorsque sa zone 21 de grand diamètre arrive contre la seconde plaque 16. L'élément de guidage 18 présente sur sa surface extérieure des dents 32 élastiques inclinées dans un sens favorisant la pénétration dans le trou 29 mais rendant difficile, voire impossible le retrait hors de ce trou 29. L'élément de guidage 18 sert alors de bouchon fermant le trou 29 et centrant l'extrémité du boulon qui dépasse de la paroi par rapport au trou 29.The bolt 11, pushed by the piston 20 and guided by the guide element 18, enters the hole 29 containing sealing grout. At the end of the piston 20 stroke, the zone 22 of the small diameter piston reaches the end of the tube 13, then at the opening of the second plate 16. As indicated above, the diameter of the zone 22 of the piston is substantially equal to the diameter of the opening of the plate 16. This part 22 of the piston is such that it can pass through this opening. A chamfer 31 is provided on the piston to facilitate its introduction through the second plate 16. By entering through the opening, the piston 20 comes to drive the guide element 18 and pushes it into the hole 29. The piston 20 is stopped when its large diameter zone 21 comes against the second plate 16. The guide element 18 has elastic teeth 32 on its outer surface inclined in a direction favoring penetration into the hole 29 but making it difficult or even impossible withdrawal from this hole 29. The guide element 18 then serves as a plug closing the hole 29 and centering the end of the bolt which protrudes from the wall with respect to the hole 29.
Le boulon 11 est posé. La glissière 5 et le magasin 10 sont écartés de la paroi 28. L'appareil 1 est prêt à poser un autre boulon 11. Le magasin représenté au dessin comporte six tubes 13 contenant chacun un boulon 11, l'opération de boulonnage décrite ci-dessus peut donc être répétée cinq fois avant soit de reprendre l'avancement de la galerie, soit de recharger le magasin 10 avec d'autres boulons 11. Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution décrite ci-dessus à titre d'exemple non limitatif ; elle en embrasse au contraire toutes les variantes.The bolt 11 is installed. The slide 5 and the magazine 10 are spaced from the wall 28. The device 1 is ready to install another bolt 11. The magazine shown in the drawing has six tubes 13 each containing a bolt 11, the bolting operation described above above can therefore be repeated five times before either resuming the advancement of the gallery, or reloading the magazine 10 with other bolts 11. As it goes without saying, the invention is not limited to the sole form of execution described above by way of nonlimiting example; on the contrary, it embraces all its variants.
Ainsi par exemple, le dispositif de boulonnage peut être placé de manière différente par rapport à la glissière de forage. Ce dispositif peut même être indépendant de cette glissière et être monté sur une autre glissière qui lui serait propre. On aurait alors deux glissières parallèles, l'une pour le dispositif de foration et l'autre pour le dispositif de boulonnage. De très nombreuses variantes quant aux postions relatives de ces deux dispositifs sont envisageables.For example, the bolting device can be placed differently from the drilling slide. This device can even be independent of this slide and be mounted on another slide which is specific to it. There would then be two parallel slides, one for the drilling device and the other for the bolting device. Of very many variants as to the relative positions of these two devices are possible.
Le tube d'injection de coulis de scellement n'est pas forcément monté parmi les autres tubes du magasin. Ce tube ne fait pas partie intégrante de l'invention. Il est pensable d'avoir un dispositif d'injection de coulis de scellement distinct de l'appareil de foration et de boulonnage sans sortir du cadre de l'invention. De même, le nombre de tubes destinés à recevoir des boulons n'est pas limité à six. Ce nombre peut être supérieur ou inférieur.The grout injection tube is not necessarily fitted among the other tubes in the store. This tube is not an integral part of the invention. It is conceivable to have a sealing grout injection device separate from the drilling and bolting apparatus without departing from the scope of the invention. Similarly, the number of tubes intended to receive bolts is not limited to six. This number can be higher or lower.
Le calculateur utilisé peut être remplacé par un séquenceur hydraulique ou par un automate tout en permettant à l'appareil décrit ci-dessus de fonctionner de la même façon.The computer used can be replaced by a hydraulic sequencer or by a PLC while allowing the device described above to operate in the same way.
Bien entendu, cet appareil peut être utilisé dans toutes les positions, pour mettre des boulons dans le sol par exemple, et peut utiliser tous types de boulons. Of course, this device can be used in all positions, to put bolts in the ground for example, and can use all types of bolts.
