Abstract
Description
La présente invention concerne un procédé de construction d'un ouvrage enterré, notamment d'un parc de stationnement, préservant des obstacles au moins partiellement enterrés de la périphérie de l'ouvrage tels que des arbres.The present invention relates to a method of constructing a buried structure, in particular a parking lot, preserving obstacles at least partially buried in the periphery of the structure, such as trees.
La largeur utile courante d'un parc de stationnement souterrain est d'environ 15 mètres. Une allée centrale de 5 mètres permet d'accéder à deux rangées latérales de places de stationnement en vis-à-vis de 5 mètres chacune.The current useful width of an underground car park is approximately 15 meters. A central aisle of 5 meters provides access to two lateral rows of opposite parking spaces of 5 meters each.
La construction de la dalle supérieure et/ou celle des piédroits de l'ouvrage nécessite en général que l'espace sous-terrain situé au-dessus de celui-ci soit libre ou libéré temporairement pendant la période des travaux, sauf si ceux-ci sont effectués suivant les techniques minières traditionnelles anciennes, peu mécanisées et donc coûteuses.The construction of the upper slab and / or that of the pedestals of the structure generally requires that the underground space located above it be free or temporarily freed during the work period, unless these are carried out using old traditional mining techniques, which are not very mechanized and therefore expensive.
De même, il est nécessaire pour les engins de forage ou de manutention que l'espace aérien situé au-dessus de l'ouvrage à construire soit dégagé de tout obstacle pour des raisons de sécurité et de commodité.Likewise, it is necessary for drilling or handling equipment that the air space situated above the structure to be constructed be clear of any obstacle for reasons of safety and convenience.
Lorsqu'un ouvrage souterrain tel qu'un parc de stationnement doit être aménagé sous la voie publique, il se trouve fréquemment que la distance entre les deux rangées d'arbres bordant cette voie soit justement de l'ordre de 15 mètres. Il en résulte par conséquent que les racines de ces arbres occupent l'espace sous-terrain situé au niveau des piédroits de l'ouvrage et que les volumes aériens occupés par leurs ramures sont interceptés par les engins de forage et de manutention.When an underground structure such as a parking lot must be laid out under the public thoroughfare, it often happens that the distance between the two rows of trees bordering this thoroughfare is precisely around 15 meters. It therefore follows that the roots of these trees occupy the underground space located at the level of the pedestals of the structure and that the overhead volumes occupied by their antlers are intercepted by drilling and handling equipment.
La figure 1 représente un parc de stationnement enterré 1 avec sa dalle 2 et ses piédroits 3, enterré sous une voie publique 4 bordée d'immeubles 5, une rangée d'arbres 6 étant plantée entre chaque bord de la voie 4 et l'immeuble adjacent 5. On a représenté en hâchures les emplacements qui doivent être libérés pour la réalisation de l'ouvrage enterré 1.FIG. 1 represents a buried parking lot 1 with its
Parmi ces emplacements figurent notamment les arbres 6 dont les racines 7 occupent sensiblement une demi-sphère enterrée et les ramures une partie aérienne qui peut être assimilée une sphère ou à un cylindre.Among these locations are in particular the
La construction de l'ouvrage 1 nécessite par conséquent que soient sacrifiés les arbres bordant la voie publique.The construction of the structure 1 consequently requires that the trees bordering the public road be sacrificed.
Le document EP-A- 0 188 282 décrit un procédé pour rendre constructible une masse de terrain en réalisant autour d'elle une enveloppe étanche élastique, étanche à l'eau et à l'air. Ce procédé ne permet pas d'effectuer une fouille en dessous de cette paroi d'étanchéité en supportant des obstacles qui se trouvent au-dessus de cette dernière.The document EP-A-0 188 282 describes a method for making a mass of land constructible by producing around it an elastic waterproof envelope, waterproof and airtight. This method does not allow a search to be carried out below this sealing wall by supporting obstacles which are located above the latter.
Le document DE-A-1 801 892 décrit un procédé pour rigidifier une structure dans le sol qui consiste à réunir des pieux par des lignes d'injection horizontales recoupant lesdits pieux, mais ce document ne prévoit pas de réaliser de fouilles en dessous d'obstacles supportés par des rideaux d'éléments de soutènement.Document DE-A-1 801 892 describes a method for stiffening a structure in the ground which consists in joining piles by horizontal injection lines intersecting said piles, but this document does not provide for carrying out excavations below obstacles supported by curtains of supporting elements.
La présente invention vise à pallier cet inconvénient.The present invention aims to overcome this drawback.
A cet effet, l'invention à pour objet un procédé de construction d'un ouvrage enterré, notamment d'un parc de stationnement, préservant les obstacles au moins partiellement enterrés à la périphérie ou au-dessus de l'ouvrage tels que des arbres, caractérisé par le fait que l'on réalise, préalablement au creusement de l'ouvrage, un rideau d'éléments allongés de soutènement des obstacles, lesdits éléments étant enfoncés dans le sol sensiblement à la périphérie de ce dernier vers l'extérieur de ce dernier et sous lesdits obstacles, puisque l'on réalise la fouille partiellement en dessous du rideau d'éléments de soutènement.To this end, the invention relates to a method of constructing a buried structure, in particular a parking lot, preserving obstacles at least partially buried on the periphery or above the structure such as trees , characterized by the fact that, before the digging of the structure, a curtain of elongated elements for supporting obstacles is produced, said elements being driven into the ground substantially at the periphery of the latter towards the outside of this last and under said obstacles, since the excavation is carried out partially below the curtain of support elements.
Selon un premier mode de réalisation, le soutènement est réalisé à partir de la surface selon un plan incliné par rapport à la verticale en permettant ainsi la construction de parcs souterrains ou autres ouvrages enterrés sans déraciner les arbres ni intercepter leurs racines ou endommager leur ramure.According to a first embodiment, the support is produced from the surface in an inclined plane with respect to the vertical, thus allowing the construction of underground parks or other buried structures without uprooting the trees or intercepting their roots or damaging their antlers.
Les éléments de soutènement sont de préférence espacés transversalement, la cohésion du terrain empêchant celui-ci de s'écouler entre les éléments de soutènement.The support elements are preferably spaced transversely, the cohesion of the ground preventing it from flowing between the support elements.
Dans le cas où cette cohésion est insuffisante, on peut traiter le terrain, par exemple par les procédés décrits dans les documents FR-A-2 528 441, FR-A-2 583 441 ou FR-A- 2 585 698, ces procédés ne présentant aucun danger pour la survie des arbres.If this cohesion is insufficient, the ground can be treated, for example by the methods described in documents FR-A-2 528 441, FR-A-2 583 441 or FR-A- 2 585 698, these methods not endangering the survival of the trees.
Dans ce mode de réalisation de l'invention, il est avantageux de réaliser des pieux sensiblement verticaux entre les obstacles, par exemple sous la forme de tronçons de parois moulées sensiblement perpendiculaires à la périphérie de l'ouvrage, de fixer des poutres d'appui sensiblement horizontales sur lesdits pieux, et de mettre en appui sur lesdites poutres les extrémités supérieures des éléments de soutènement.In this embodiment of the invention, it is advantageous to make substantially vertical piles between the obstacles, for example in the form of sections of molded walls substantially perpendicular to the periphery of the structure, to fix support beams substantially horizontal on said piles, and to bear on said beams the upper ends of the supporting elements.
Dans un second mode de réalisation de l'invention, on réalise une excavation à la périphérie des obstacles à soutenir et l'on engage à partir de cette excavation les poutres d'appui sous les obstacles à soutenir.In a second embodiment of the invention, an excavation is carried out at the periphery of the obstacles to be supported and the support beams are engaged from this excavation under the obstacles to be supported.
Dans ce cas, les poutres d'appui peuvent être inclinées ou même sensiblement horizontales. Elles peuvent reposer sur des éléments porteurs qui sont utilisés pour maintenir les parois de l'excavation.In this case, the support beams can be inclined or even substantially horizontal. They can rest on load-bearing elements which are used to hold the walls of the excavation.
On décrira maintenant à titre d'exemples non limitatifs, deux modes de réalisation particuliers de l'invention en se référant au dessin annexé dans lequel :
- la figure 1 est une coupe illustrant le problème posé,
- la figure 2 est une vue en demi-coupe transversale d'un premier mode de réalisation de l'invention,
- la figure 3 est une demi-vue de dessus, correspondant à la figure 2,
- la figure 4 est une vue en coupe transversale de l'ouvrage terminé,
- et la figure 5 est une vue en coupe transversale d'un second mode de réalisation de l'invention.
- FIG. 1 is a section illustrating the problem posed,
- FIG. 2 is a view in half cross-section of a first embodiment of the invention,
- FIG. 3 is a half view from above, corresponding to FIG. 2,
- FIG. 4 is a cross-sectional view of the finished structure,
- and Figure 5 is a cross-sectional view of a second embodiment of the invention.
Si l'on se réfère aux figures 2 et 3 qui représentent la même voie publique 4 bordée d'arbres 6 que la figure 1, on voit comment selon le premier mode de réalisation l'on réalise entre les arbres 6 des pieux ou barrettes verticales 8 selon la technique bien connue des parois moulées.If we refer to Figures 2 and 3 which show the same
Ces barrettes 8 sont réalisées entre les arbres 6 de manière à ne pas les endommager et à ne pas intercepter leurs racines.These
Bien entendu, ces barrettes 8 qui ont pour objet de constituer des éléments supports verticaux pourraient être remplacées, par exemple par des pieux forés définitifs ou provisoires.Of course, these
Des poutres d'appui horizontales sont ensuite fixées sur les barrettes 8 par tout moyen convenable, par exemple par encastrement ou à l'aide d'inserts métalliques. Ces poutres horizontales sont par exemple réalisées sous la forme de poutres en béton 9 comme représenté à la figure 2, ou sous la forme de poutrelles métalliques 9′ comme représenté à la figure 3.Horizontal support beams are then fixed to the
On met ensuite en place dans le terrain les éléments de soutènement obliques suivant par exemple un angle de 45°, qui dans le cas présent sont constitués par des tubes métalliques 10. En milieu urbain, l'enfoncement des tubes 10 est de préférence effectué par forage afin d'éviter tout choc ou vibration sur l'environnement.The oblique support elements are then placed in the ground, for example at an angle of 45 °, which in the present case are constituted by
On voit sur la figure 2 comment les tubes 10 sont enfoncés perpendiculairement à la périphérie de l'ouvrage, en étant inclinés vers le bas en direction de l'extérieur de celui-ci, et comment leur extrémité supérieure est en appui sur les poutres horizontales 9.We see in Figure 2 how the
La longueur des tubes 10 est telle qu'ils ne puissent endommager les fondations des immeubles riverains 5.The length of the
Les tubes 10 sont par ailleurs enfoncés de telle manière qu'ils ne risquent point d'intercepter la demi-sphère 7 des racines des arbres 6.The
On comprend que, lors du creusement ultérieur de l'ouvrage, le terrain situé au-dessus des tubes 10 est soutenu par ces derniers qui se trouvent d'une part encastrés dans le sol à leur extrémité inférieure et d'autre part en appui sur les poutres 9 à leur partie supérieure.It is understood that, during the subsequent digging of the structure, the ground located above the
On peut ensuite couler la dalle supérieure 2 de l'ouvrage, cette dalle incluant éventuellement les poutres horizontales 9 et 9′, puis réaliser l'ouvrage sous-terrain par tout moyen connu à l'abri de cette dalle comme montré à la figure 4, le soutènement des terres et des arbres 6 étant réalisé par les tubes 10 qui constituent les éléments de soutènement.We can then pour the
On a représenté sur la figure 5 un second mode de réalisation de l'invention, dans lequel les éléments de soutènement 10 sont disposés d'une manière sensiblement horizontale en-dessous des obstacles qui sont situés au-dessus de l'ouvrage à construire.FIG. 5 shows a second embodiment of the invention, in which the
Dans ce second mode de réalisation, on réalise tout d'abord des parois verticales moulées dans le sol 11, 12 et 13, par des techniques habituelles. Ces parois sont réalisées selon des lignes qui ne comportent pas d'obstacles à la surface du sol.In this second embodiment, first of all vertical walls are molded into the
On voit sur la figure 5 que la partie de l'ouvrage qui est située à gauche de la paroi 12 comporte des obstacles schématiquement représentés tels que des arbres ou des canalisations qui doivent être conservés, alors que la partie située à droite de la paroi 12 n'en comporte pas.It can be seen in FIG. 5 that the part of the structure which is situated to the left of the
Comme représenté sur la figure 5, on a réalisé dans cette partie de droite les dalles 14 et 15 qui délimitent le volume 16.As shown in FIG. 5, in this part on the right, the
Pour cette réalisation, on a d'abord excavé le terrain se trouvant au-dessus de l'emplacement de la dalle 14, ce qui a permis de réaliser cette dernière, puis on a excavé le volume 16, ce qui a permis la réalisation de la dalle 15, à la suite de quoi, le volume situé au-dessus de la dalle 14 a été ramblayé, ce qui a permis de libérer le terrain qui est au-dessus de la dalle 14.For this realization, we first excavated the land located above the location of the slab 14, which made it possible, then we excavated the
A ce stade des travaux, l'on met en place les éléments de soutènement 10 qui peuvent être constitués par des tubes ou des poutrelles que l'on engage dans des cavités sensiblement horizontales, qui sont réalisées en-dessous des obstacles.At this stage of the work, the supporting
L'extrémité gauche des éléments de soutènement est encastrée dans la paroi 13 et dans le terrain qui est situé à gauche de cette dernière, alors que l'extrémité droite des éléments 10 se trouve supportée par la paroi 12 qui constitue l'élément de support vertical.The left end of the retaining elements is embedded in the wall 13 and in the ground which is located to the left of the latter, while the right end of the
On réalise avantageusement une poutre 9, disposée perpendiculairement au plan de la figure 5, qui réunit les extrémités des éléments de soutènement 10 et qui rigidifie la partie haute de la paroi 12.A
Le terrain étant ainsi maintenu au-dessus des éléments de soutènement 10, il est possible de procéder à l'excavation du volume 17 qui est situé en-dessous de cette partie du terrain, ce qui permet ensuite de réaliser la dalle 18 qui est située immédiatement au-dessous des éléments de soutènement 10 et qui est supportée par les parois 12 et 13.The ground being thus maintained above the supporting
On peut alors couler la partie gauche de la dalle 15 et après des fouilles successives, les planchers des étages inférieurs.We can then pour the left part of the
On voit que selon ce seconc mode de réalisation de l'invention, l'excavation d'un premier niveau à côté des obstacles qui doivent être soutenus, permet de placer les éléments de soutènement dans une position horizontale ou sensiblement horizontale, en-dessous des dits obstacles, ce qui, dans certains cas, permet d'augmenter notablement le volume utile en-dessous desdits obstacles.We see that according to this second embodiment of the invention, the excavation of a first level next to the obstacles which must be supported, makes it possible to place the support elements in a horizontal or substantially horizontal position, below the said obstacles, which, in certain cases, makes it possible to significantly increase the useful volume below said obstacles.
On comprend ainsi que le procédé selon l'invention permet la libération quasi-totale de l'emprise de l'ouvrage, à l'exception des trémies d'accès au chantier.It is thus understood that the method according to the invention allows almost complete release of the footprint of the structure, with the exception of the access hoppers to the site.
Diverses variantes et modifications peuvent bien entendu être apportées à la description qui précède sans sortir pour autant du cadre ni de l'esprit de l'invention.Various variants and modifications can of course be made to the above description without departing from the scope or the spirit of the invention.
On comprend en particulier que l'invention permet de sauvegarder des obstacles tels que des arbres qui sont situés aussi bien à la périphérie qu'au centre de l'emprise de l'ouvrage souterrain à construire.It is understood in particular that the invention makes it possible to save obstacles such as trees which are situated both at the periphery and at the center of the right-of-way of the underground structure to be constructed.
