Abstract
Description
La présente invention a pour objet un appareil d'excavation du sol pour la réalisation de pieux moulés.The present invention relates to an excavating apparatus of the ground for producing molded piles.
De façon plus précise la présente invention concerne un appareil qui permet de réaliser le creusement dans le sol d'un puits pour réaliser ultérieurement un pieu moulé par remplissage à l'aide de béton et éventuellement d'une armature du puits ainsi réalisé.More specifically, the present invention relates to a apparatus that allows digging into the ground of a well for subsequently make a pile molded by filling with concrete and possibly a reinforcement of the well thus produced.
De façon encore plus précise, l'invention concerne des appareils de ce type dont l'outil d'excavation est constitué par une tarière.Even more precisely, the invention relates to devices of this type whose excavation tool is constituted by an auger.
L'excavation du sol à l'aide d'une tarière pour réaliser un puits cylindrique peut mettre en oeuvre deux techniques d'excavation du sol respectivement appelées forage et refoulement. La première technique consiste, à l'aide d'une tarière comportant une ou plusieurs pales, à creuser le sol et à provoquer la remontée du sol excavé au fur et à mesure de cette excavation de manière à obtenir ainsi un puits cylindrique qui sera ultérieurement rempli de béton ou de matériaux analogues. La technique de refoulement consiste à repousser à l'aide de la tarière le sol excavé à la périphérie et à la pointe du puits ainsi réalisé.Excavating the soil with an auger to make a well cylindrical can implement two techniques of soil excavation respectively called drilling and pushing. The first technique consists, using an auger with one or more blades, to dig the soil and cause the excavated soil to rise as measuring this excavation so as to obtain a cylindrical well which will later be filled with concrete or similar materials. The Discharge technique involves repelling the soil with the aid of the auger excavated at the periphery and the well tip thus produced.
Dans la présente demande de brevet, par excavation, il faut entendre un terme générique recouvrant à la fois les techniques de forage et les techniques de refoulement. Il faut encore préciser que, le plus souvent, avec les appareils connus, l'excavation du puits résulte de la combinaison d'une partie relevant du forage et d'une partie relevant du refoulement latéral.In this patent application, by excavation, it is necessary to hear a generic term covering both drilling techniques and the techniques of repression. It should be noted that the most often, with the known apparatuses, the excavation of the well results from the combination of a part of the borehole and a part of the lateral discharge.
Il faut également préciser que, par taux de refoulement, on entend par rapport à la section totale du puits excavé la fraction de cette section qui résulte du phénomène de refoulement dû à l'outil utilisé.It should also be noted that, by the rate of refoulement, means in relation to the total section of the well excavated the fraction of that section that results from the phenomenon of repression due to the tool used.
A la suite de tests effectués sur une zone où des pieux moulés doivent être réalisés, on peut déterminer que certains pieux devront être réalisés essentiellement par refoulement et d'autres essentiellement par forage. On peut également arriver à la conclusion que pour la réalisation d'un même pieu moulé, certaines tranches de l'excavation devront être réalisées par refoulement et d'autres par forage en fonction de la nature des différentes couches de terrain.Following tests on an area where molded piles must be realized, it can be determined that certain piles will have to be carried out mainly by repression and others essentially by drilling. It can also be concluded that for the realization of the same molded pile, some sections of the excavation must be carried out by repression and others by drilling according to the nature different layers of terrain.
On connaít des appareils à tarière continue qui permettent l'excavation de puits pour la réalisation de pieux moulés qui sont efficaces par forage ou par refoulement tant que le diamètre du puits à excaver reste limité. En revanche, de tels appareils ne permettent pas dans des conditions économiques acceptables et notamment avec des moyens moteurs d'entraínement en rotation de la tarière communément utilisés dans ce genre d'appareil, d'excaver le puits en faisant varier, selon le sol ou le résultat recherché le rapport forage/refoulement sur une gamme de diamètres étendue.We know continuous auger devices that allow the excavation of wells for the realization of molded piles which are effective by drilling or pushing as long as the diameter of the well to be excavated remains limited. On the other hand, such devices do not acceptable economic conditions and in particular with drive motors in rotation of the auger commonly used in this type of apparatus, to excavate the well by varying, depending on the soil or the desired result the drill / discharge ratio over a range of large diameters.
Les demandes de brevet européen EP 131 562 et EP 853 162 décrivent notamment des dispositifs et des procédés pour la réalisation de pieux moulés. Cependant, ces dispositifs ne permettent pas de résoudre le problème énoncé ci-dessus.European Patent Applications EP 131,562 and EP 853,162 describe in particular devices and methods for carrying out molded piles. However, these devices do not solve the problem stated above.
Un objet de la présente invention est de fournir un appareil d'excavation du sol pour la réalisation de pieux moulés qui permette d'utiliser, en fonction des nécessités, les techniques de forage ou de refoulement en particulier pour la réalisation de l'excavation de diamètres compris entre 0,3 et 1,2 mètres et de préférence entre 0,4 et 0,8 mètres.An object of the present invention is to provide a device soil excavation for the production of molded piles which allows to use, where necessary, drilling or backflow in particular for carrying out the excavation of diameters between 0.3 and 1.2 meters and preferably between 0.4 and 0.8 meters.
Pour atteindre ce but, selon l'invention, l'appareil d'excavation du sol pour la réalisation de pieux moulés se caractérise en ce qu'il comprend :
- une première tarière comprenant une première âme de diamètre d1 terminée par une pointe dont le diamètre extérieur n'est pas supérieur à celui de l'âme, et au moins une pale en forme d'hélice s'étendant sensiblement sur toute la longueur de l'âme, le diamètre extérieur de la pale étant égal à d2 ;
- une deuxième tarière comprenant une deuxième âme creuse de diamètre interne d3 > d2 dans laquelle est montée libre en translation ladite première tarière, et au moins une pale en forme d'hélice s'étendant sensiblement sur toute la longueur de ladite deuxième âme, et de diamètre externe d4 ;
- une première tête de forage pour la mise en rotation de ladite première tarière et pour appliquer une force verticale à ladite tarière ;
- des premiers moyens pour commander la vitesse de rotation, le couple et la force verticale appliqués à ladite première tarière ;
- des premiers moyens pour mesurer la vitesse effective d'enfoncement de ladite première tarière ;
- une deuxième tête de forage indépendante de la première tête pour la mise en rotation de ladite deuxième tarière et pour appliquer une force verticale à ladite tarière ;
- des deuxièmes moyens pour commander la vitesse de rotation, le couple et la force verticale appliqués à ladite deuxième tarière ; et
- des deuxièmes moyens pour mesurer la vitesse effective d'enfoncement de la deuxième tarière.
- a first auger comprising a first core of diameter d 1 terminated by a tip whose outer diameter is not greater than that of the core, and at least one helical blade extending substantially over the entire length of the core, the outer diameter of the blade being equal to d 2 ;
- a second auger comprising a second hollow core of internal diameter d 3 > d 2 in which is mounted free in translation said first auger, and at least one helical blade extending substantially over the entire length of said second core, and of external diameter d 4 ;
- a first drill head for rotating said first auger and for applying a vertical force to said auger;
- first means for controlling rotational speed, torque and vertical force applied to said first auger;
- first means for measuring the effective driving speed of said first auger;
- a second drilling head independent of the first head for rotating said second auger and for applying a vertical force to said auger;
- second means for controlling rotational speed, torque and vertical force applied to said second auger; and
- second means for measuring the effective driving speed of the second auger.
On comprend que grâce à l'utilisation de deux tarières concentriques présentant chacune sur la plus grande partie de leur longueur au moins une pale en forme d'hélice, on peut, par le contrôle de l'entraínement en rotation de ces deux tarières et par le contrôle de la position relative de ces deux tarières, obtenir des configurations variées d'excavation du sol par forage et/ou par refoulement pour des profondeurs différentes en fonction notamment de la nature du sol.We understand that thanks to the use of two augers concentrics each presenting on most of their the length of at least one blade in the form of a helix, it is possible, by the control of the rotational drive of these two augers and the control of the relative position of these two augers, get various configurations soil excavation by drilling and / or discharge for depths depending on the nature of the soil.
De préférence, on a la relation 0,5 d2 < d1 < 0,75 d2.Preferably, the relationship is 0.5 d 2 <d 1 <0.75 d 2 .
Il est en particulier important de souligner qu'en commandant la rotation simultanée des deux tarières dans des conditions convenables, il est possible d'obtenir un taux de refoulement dans le puits excavé correspondant au diamètre de l'âme de la deuxième tarière, c'est-à-dire de la tarière extérieure. Ce résultat est obtenu notamment du fait que la partie du sol contenue dans l'hélice de la tarière intérieure et disposée dans l'âme de la tarière extérieure constitue l'équivalent d'un bouchon permettant le refoulement du sol sur toute la section correspondant au diamètre de l'âme de la tarière extérieure, bien que cette âme soit creuse, pour permettre le passage de la tarière intérieure.In particular, it is important to emphasize that simultaneous rotation of the two augers under suitable conditions, It is possible to obtain a discharge rate in the excavated well corresponding to the diameter of the soul of the second auger, that is to say the external auger. This result is obtained in particular because the part of the soil contained in the propeller of the inner auger and arranged in the soul of the outer auger constitutes the equivalent of a plug allowing the soil to be discharged over the entire section corresponding to the diameter of the soul of the outer auger, although this soul is hollow, to allow the passage of the inner auger.
D'autres caractéristiques et avantages de l'invention apparaítront mieux à la lecture de la description qui suit d'un mode de réalisation de l'invention donné à titre d'exemple non limitatif. La description se réfère aux figures annexées sur lesquelles :
- la figure 1 représente en coupe verticale un appareil d'excavation et ses principaux éléments de commande ; et
- la figure 2 montre l'extrémité inférieure de la tarière intérieure équipée d'un tube plongeur.
- Figure 1 shows in vertical section an excavating apparatus and its main control elements; and
- Figure 2 shows the lower end of the inner auger equipped with a dip tube.
En se référant tout d'abord à la figure 1, on va décrire l'ensemble de l'appareil d'excavation pour la réalisation de pieux moulés. Referring first to Figure 1, we will describe the entire excavation apparatus for producing molded piles.
Sur cette figure, on a représenté une première tarière 12 ou
tarière intérieure qui comporte une âme 14 de diamètre d1 et dont
l'extrémité inférieure 14a est équipée d'une pointe 16 favorisant la
pénétration de la tarière dans le sol et pouvant jouer le rôle de bouchon
de refoulement. Cette pointe 16, qui peut présenter différentes
configurations, présente un diamètre extérieur maximal au plus égal au
diamètre de l'âme 14. L'âme 14 est équipée d'une pale 18 en forme
d'hélice qui s'étend sensiblement sur toute la longueur de l'âme 14 depuis
son extrémité inférieure 14a jusqu'à proximité de son extrémité supérieure
14b. On appellera d2 le diamètre externe de la pale en forme d'hélice 18
de la tarière 12.In this figure, there is shown a
Comme cela est bien connu, l'extrémité supérieure 14b de
l'âme 14 coopère avec une première tête de forage 18 dont la fonction est
la mise en rotation de la tarière 14 en imprimant à celle-ci une vitesse de
rotation et un couple définis par un circuit de commande 20. L'autre
fonction de la tête de forage 18 est d'appliquer à la tarière 12 une force
verticale de pénétration dans le sol, réglée par le circuit de commande 22.
En outre, la tête de forage 18 est munie d'un capteur 24 qui permet de
déterminer la profondeur ou la vitesse de pénétration de l'extrémité de la
tarière dans le sol dans l'excavation de l'extrémité inférieure 14a de la
tarière intérieure 12.As is well known, the upper end 14b of
the
L'appareil comprend également une tarière extérieure 26 qui
comporte une âme creuse 28 et dont l'extrémité inférieure 28a est donc
ouverte. L'extrémité supérieure 28b de l'âme 28 coopère avec une
deuxième tête de forage 30 indépendante de la première tête de forage
18. L'âme 28 de la tarière extérieure 26 est équipée sur sa face externe
d'au moins une pale en forme d'hélice 32 qui s'étend depuis son extrémité
inférieure 28a jusqu'à proximité de son extrémité supérieure 28b. La tête
de forage 30 est associée à un circuit de commande de la vitesse de
rotation et du couple et référencée 34, à un dispositif d'application d'une
force 36, et à un capteur de mesure 40 de la profondeur de l'extrémité
inférieure de la tarière 26, dans l'excavation.The apparatus also includes an
De préférence, le diamètre d1 de l'âme de la tarière intérieure
12 et le diamètre d2 de la spire de cette même tarière sont choisis de telle
manière que le rapport de la surface de la section droite de l'âme sur la
surface du cercle de diamètre d2 correspondant à la pale soit compris
entre 25% et 80% et de préférence entre 30% et 50%.Preferably, the diameter d 1 of the core of the
Cette caractéristique permet d'assurer qu'en commandant
convenablement la rotation de la tarière intérieure 12, on pourra obtenir
un taux de refoulement du sol compris entre ces deux valeurs. De même,
de préférence, le rapport entre le diamètre d3 de l'âme 28 de la tarière
externe et le diamètre d4 de la pale 32 en forme d'hélice de la tarière
externe 28 est choisi de telle manière que le rapport entre les surfaces
des cercles de diamètre d3 et d4 soit compris entre 25% et 60% et de
préférence entre 30% et 50%.This feature makes it possible to ensure that by properly controlling the rotation of the
Cette dernière caractéristique permet, lorsque les tarières
intérieure 12 et extérieure 26 sont commandées convenablement en
rotation, d'obtenir un taux de refoulement compris dans les valeurs
mentionnées ci-dessus. En effet, dans ce cas, le sol emprisonné entre
l'âme de la tarière interne, les spires de la pale de la tarière interne et la
paroi interne de l'âme creuse 28 de la tarière externe, constitue un
bouchon qui permet d'obtenir un refoulement correspondant à la section
droite de l'âme creuse de la tarière externe.This last characteristic allows, when the augers
inner 12 and outer 26 are suitably controlled by
rotation, to obtain a rate of repression included in the values
mentioned above. Indeed, in this case, the ground trapped between
the internal auger core, the inner auger blade turns and the
inner wall of the
On comprend que, grâce aux dispositions de l'invention et notamment aux caractéristiques des tarières interne et externe et au fait que ces deux tarières peuvent être commandées séparément en translation verticale et en rotation, il est possible d'obtenir une grande flexibilité dans les opérations d'excavation en vue de réaliser un pieu moulé. En effet, il est possible de passer d'un travail essentiellement en refoulement à un travail en forage, à toute profondeur convenable ; il est également possible de ne provoquer le déplacement que d'une des tarières, l'autre étant momentanément au repos, puis de provoquer l'action de la deuxième tarière ultérieurement.It is understood that, thanks to the provisions of the invention and in particular the characteristics of the internal and external auger and the fact that these two augers can be ordered separately in vertical translation and rotation, it is possible to obtain a large flexibility in excavation operations to achieve a pile mold. Indeed, it is possible to go from a job essentially to return to work in drilling at any suitable depth; he is also possible to cause the displacement of only one of augers, the other being momentarily at rest, then provoking the action of the second auger later.
Il est également possible, lorsque l'on veut faire travailler la
tarière interne 12 en forage, de commander la rotation de celle-ci dans le
sens du vissage et de commander la rotation de la tarière externe dans le
sens opposé, ce qui favorise la remontée des déblais à l'intérieur de
l'âme creuse de la tarière externe, sous l'effet de la rotation de la pale de
la tarière interne.It is also possible, when one wants to make work the
Sur la figure 2, on a représenté un mode perfectionné de
réalisation dans lequel la tarière interne 12 est équipée d'un tube plongeur
50 permettant, après la réalisation de l'excavation par forage et/ou
refoulement, d'acheminer le béton ou matériau analogue nécessaire à la
réalisation du pieu moulé à l'intérieur de l'excavation réalisée.FIG. 2 shows an improved mode of
embodiment in which the

Ainsi, il est possible de séparément actionner les deux tarières qui peuvent travailler simultanément ou en alternance. Comme on l'a déjà indiqué, il est possible de modifier le mode de fonctionnement des tarières (refoulement, forage) durant la réalisation d'une même excavation en fonction des variations des caractéristiques du sol dans lequel l'excavation est creusée.Thus, it is possible to separately operate the two augers who can work simultaneously or alternately. As we already have indicated, it is possible to modify the operating mode of the augers (backflow, drilling) during the realization of the same excavation in function of variations in soil characteristics in which the excavation is dug.
