Abstract
Description
La présente invention a pour objet un nouveau procédé pour butonner ou maintenir latéralement les parois verticales de fouilles profondes de manière à permettre le terrassement sans entraîner la destruction de ces parois.The present invention relates to a new method for butting or laterally holding the vertical walls of deep excavations so as to allow earthworks without causing the destruction of these walls.
Il est connu pour réaliser des ouvrages dans le sol qui peuvent présenter des profondeurs importantes, de réaliser les parois verticales de soutènement desdits ouvrages en forant des tranchées sous une boue de betonite qui maintient les parois des tranchées, puis en substituant la boue par du coulis ou du béton lequel, en durcissant, réalise les parois verticales de l'ouvrage avant que l'on procède au terrassement de son volume intérieur.It is known to make works in the ground which can have significant depths, to realize the vertical retaining walls of said works by drilling trenches under a concrete mud which maintains the walls of the trenches, then by replacing the mud with grout or concrete which, when hardening, creates the vertical walls of the structure before the earthwork of its interior volume is carried out.
Selon la technique actuellement employée, on assure le butonnage ou maintien latéral des parois verticales durant la fouille en réalisant entre différentes étapes de la fouille au moins un plancher qui peut ainsi supporter des efforts horizontaux exercés par le terrain à l'extérieur des parois verticales.According to the currently used technique, the vertical walls are butted or held in place during the excavation by performing, between different stages of the excavation, at least one floor which can thus withstand horizontal forces exerted by the ground outside the vertical walls.
Cette manière de faire implique que l'on réalise au préalable les appuis qui sont nécessaires pour supporter les planchers intermédiaires.This way of proceeding implies that the supports which are necessary to support the intermediate floors are carried out beforehand.
Ces appuis sont obtenus en forant des puits qui vont jusqu'à la base du bâtiment et dans lesquels on introduit des poteaux préfondés et qui permettent de supporter les planchers intermédiaires.These supports are obtained by drilling wells which go to the base of the building and into which pre-ground posts are introduced and which allow the intermediate floors to be supported.
Le procédé selon l'invention permet de réaliser la fouille d'une manière plus simple, plus rapide et plus économique.The method according to the invention makes it possible to carry out the search in a simpler, faster and more economical manner.
La présente invention a pour objet un procédé pour butonner ou maintenir les parois verticales de soutènement de fouilles profondes, caractérisé par le fait qu'après avoir réalisé librement la fouille sur une profondeur compatible avec la résistance des parois de soutènement, on réalise sur le fond de la fouille une dalle anneau qui prend appui par sa périphérie contre les parois verticales de soutènement et qui repose sur le fond de la fouille; qu'après la solidification de cette dalle-anneau on la réunit pour la supporter à la partie supérieure des parois de soutènement à l'aide de haubans; puis qu'on poursuite la fouille par l'intérieur de la dalle-anneau jusqu'à l'extrémité inférieure de l'ouvrage.The subject of the present invention is a method for abutting or maintaining the vertical retaining walls of deep excavations, characterized in that after having freely carried out the excavation to a depth compatible with the resistance of the retaining walls, it is carried out on the bottom from the excavation a ring slab which bears by its periphery against the vertical retaining walls and which rests on the bottom of the excavation; that after the solidification of this slab-ring it is joined to support it at the upper part of the retaining walls using guy lines; then continue the excavation from the inside of the ring slab to the lower end of the structure.
Conformément à l'invention, il est avantageux que la dalle anneau qui pérmet pendant la fouille d'assurer la reprise des efforts horizontaux exercés par le terrain sur les parois de soutènement, soit utilisée pour constituer une partie d'un plancher intermédiaire.According to the invention, it is advantageous that the ring slab which allows during the excavation to ensure the resumption of the horizontal forces exerted by the ground on the retaining walls, is used to form part of an intermediate floor.
Ceci peut être facilement obtenu en positionnant la dalle anneau à une hauteur convenable et en lui donnant une forme correspondant à celle du plancher concerné.This can be easily obtained by positioning the ring slab at a suitable height and giving it a shape corresponding to that of the floor concerned.
Il suffit à la fin de la fouille de faire supporter la dalle anneau par les appuis prévus pour supporter le plancher et d'obturer la partie centrale ouverte de la dalle-anneau après quoi il suffit de démonter les haubans qui maintenaient la dalle-anneau pendant la fouille pour obtenir le plancher définitif.It suffices at the end of the excavation to support the ring slab by the supports provided to support the floor and to close the open central part of the ring slab after which it suffices to dismantle the shrouds which held the ring slab for the excavation to obtain the final floor.
Dans le cas de fouilles de grande profondeur qui nécessitent de reprendre à plusieurs niveaux les efforts horizontaux exercés par le terrain sur les parois de soutènement, il est possible selon l'invention de réaliser successivement plusieurs dalles anneaux qui peuvent servir avantageusement chacune de plancher intermédiaire.In the case of very deep excavations which require the horizontal forces exerted by the ground on the retaining walls to be taken up at several levels, it is possible according to the invention to make successively several ring slabs which can advantageously each serve as an intermediate floor.
Dans le but de mieux faire comprendre l'invention on va en décrire maintenant à titre d'illustration et sans aucun caractère limitatif, un mode de réalisation pris comme exemple et représenté sur le dessin annexé.In order to better understand the invention will now be described by way of illustration and without any limitation, an embodiment taken as an example and shown in the accompanying drawing.
Sur ce dessin, la figure 1 est une vue schématique en coupe verticale d'un ouvrage en sous-sol dans lequel on vient de réaliser la dalle anneau selon l'invention.
- La figure 2 est une vue de dessus correspondant à la figure 1.
- La figure 3 est une correspondant à la figure 1 après mise en place des haubans.
- La figure 4 est une vue de dessus correspondant à la figure 3.
- La figure 5 est une vue en coupe correspondant à la figure 3 après achèvement de la fouille.
- La figure 6 est une vue de dessus de la figure 5.
- Figure 2 is a top view corresponding to Figure 1.
- Figure 3 is a corresponding to Figure 1 after installation of the shrouds.
- FIG. 4 is a top view corresponding to FIG. 3.
- Figure 5 is a sectional view corresponding to Figure 3 after completion of the excavation.
- Figure 6 is a top view of Figure 5.
On a représenté sur la figure 1 une vue en coupe d'un ouvrage en cours de fouille conformément à l'invention.There is shown in Figure 1 a sectional view of a work being excavated in accordance with the invention.
Selon une technique habituelle on a réalisé sur la périphérie de l'ouvrage les parois de soutènement 1 avant de commencer la fouille.According to a usual technique, the
Lorsque les parois de soutènement ont réalisé leur prise, la fouille a été commencée jusqu'à une certain profondeur comme représenté sur la figure 1.When the retaining walls have taken hold, the excavation has been started to a certain depth as shown in Figure 1.
Conformément à l'invention on réalise alors une dalle-anneau 3 qui repose sur le fond de la fouille et qui prend appui par sa périphérie contre les parois de soutènement 1 en laissant en son centre une importante ouverture 4 comme on peut le voir sur la figure 2 lorsque la dalle-anneau 3 a effectué sa prise, on la relie par des haubans 5, de préférence articulés à chacune de leurs extrémités, à la partie haute des parois de soutènement.In accordance with the invention, a
Dans le mode de réalisation représenté sur le dessins, les extrémités inférieures des haubans 5 sont assujetties à la dalle anneau 3 au voisinage de l'ouverture 4, mais il va de soi que les haubans pourraient être assujettis en différents points de la dalle anneau 3.In the embodiment shown in the drawings, the lower ends of the
Cette opération ainsi terminée, il suffit, conformément à l'invention, de procéder ensuite à la fouille de la partie inférieure de l'ouvrage pour atteindre son niveau inférieur 6.This operation thus completed, it is sufficient, in accordance with the invention, to then search the lower part of the structure to reach its lower level 6.
L'exécution de cette deuxième partie de la fouille se trouve grandement facilitée par l'existence de l'ouverture 4 de grandes dimensions, qui permet un enlèvement facile des déblais.The execution of this second part of the excavation is greatly facilitated by the existence of the
Lorsque la fouille est terminée, comme représenté sur les figures 5 et 6, il est alors possible de procédé à la construction des planchers intermédiaires, et de réaliser les points d'appui qui soutiennent la dalle-anneau 3, ce qui permet de démonter les haubans 5.When the excavation is finished, as shown in FIGS. 5 and 6, it is then possible to proceed to the construction of the intermediate floors, and to produce the support points which support the slab-
La dalle-anneau 3 dont il ne reste plus qu'à obturer la partie centrale selon une technique conventionnelle sert ainsi d'élément de plancher. On voit que le procédé selon l'invention permet d'une manière simple et économique la réalisation de fouilles dans des ouvrages profonds, et sans qu'il soit nécessaire de réaliser dès le début de la fouille de points d'appui profonds pour soutenir le plancher qui est réalisé en premier pour soutenir les efforts horizontaux exercés par le terrain sur les parois de soutènement, afin de permettre la poursuite de la fouille.The ring slab 3 of which it remains only to close the central part according to a technique conventional thus serves as a floor element. We see that the method according to the invention allows a simple and economical way to carry out excavations in deep structures, and without it being necessary to carry out from the start of the excavation of deep support points to support the floor which is made first to support the horizontal forces exerted by the ground on the retaining walls, in order to allow the continuation of the excavation.
Il est bien entendu que le mode de réalisation qui a été décrit ci-dessous ne présente aucune caractère limitatif et qu'il pourra recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention, qui est défini par la teneur des revendications.It is understood that the embodiment which has been described below does not have any limiting nature and that it can receive any desirable modifications without departing from the scope of the invention, which is defined by the content of the claims.
Tout d'abord il va de soi que bien que l'ouvrage ait été représenté de forme parallèlépipédique, l'invention s'applique à des ouvrages dont la forme peut être quelconque.First of all, it goes without saying that although the work has been shown in a parallelepiped shape, the invention applies to works whose shape may be arbitrary.
De même on ne sortirait pas de cadre de l'invention en supportant la dalle anneau pendant la poursuite de la fouille à l'aide de haubans placés différemment.Likewise, it would not go beyond the ambit of the invention to support the ring slab during the continuation of the excavation with the help of guy wires placed differently.
