Abstract

A method is provided for building an underground construction, particularly a vehicle park, while leaving in place obstacles which are at least partially buried around the edge of the construction, e.g. trees. Before digging is begun, a curtain of elongate retaining elements for the obstacles is constructed from the surface, said elements being driven into the ground substantially around the edge of the construction, so as to be inclined outwards underneath said obstacles (6).

Description

La présente invention concerne un procédé de construction d'un ouvrage enterré, notamment 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 souterrain 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 et peu mécanisées et donc couteuses. 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. following old traditional mining techniques that 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. II en résulte par conséquent que les racines de ces arbres occupent l'espace souterrain 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 is often the case 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 montre 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 hachures les emplacements qui doivent etre libérés pour la réalisation de l'ouvrage enterré 1. Figure 1 shows a buried parking lot 1 with its slab 2 and its sidewalls 3, buried under a public road 4 bordered by buildings 5, a row of trees 6 being planted between each edge of track 4 and the building adjacent 5. There are shown in hatchings the locations which must be freed for the realization of the buried structure 1.

Parmi ces emplacements figurent notamment les arbres 6 dont les racines 7 occupent sensiblement une demi-sphère enterrée et les ramures une partie aérienne pouvant etre assimilée à une sphère ou à un cylindre. Among these locations are in particular the trees 6 whose roots 7 occupy substantially a buried half-sphere and the branches an aerial part which can be assimilated to a sphere or to a cylinder.

La construction de l'ouvrage 1 nécessite par conséquent que soient sacrifiés les arbres bordant la voie publique. The construction of the structure 1 therefore requires that the trees bordering the public road be sacrificed.

La présente invention vise à pallier cet inconvénient. The present invention aims to overcome this drawback.

A cet effet, l'invention a pour objet un procédé de construction d'un ouvrage enterré, notamment un parc de stationnement, préservant des obstacles au moins partiellement enterrés à la périphérie de l'ouvrage tels que des arbres, caractérisé par le fait que l'on réalise à partir de la surface, 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 l'ouvrage et inclinés par rapport à la verticale vers l'extérieur de l'ouvrage sous lesdits obstacles. To this end, the subject of the invention is a method of constructing a buried structure, in particular a parking lot, preserving obstacles at least partially buried at the periphery of the structure such as trees, characterized in that a curtain of elongated elements for supporting obstacles is produced from the surface, prior to the digging of the structure, said elements being driven into the ground substantially at the periphery of the structure and inclined relative to the vertical towards the outside of the structure under said obstacles.

Selon la présente invention, le soutènement est par conséquent effectué à partir de la surface selon un plan incliné par rapport à la verticale et permet par conséquent la construction de parcs souterrains ou autres ouvrages enterrés sans déraciner les arbres ni intercepter leurs racines ni endommager leur ramure. According to the present invention, the support is therefore carried out from the surface in an inclined plane relative to the vertical and therefore allows the construction of underground parks or other buried structures without uprooting the trees or intercepting their roots or damaging their antlers .

De préférence, les éléments de soutènement sont espacés transversalement, la cohésion du terrain empêchant celui-ci de s'écouler entre les éléments de soutènement. Preferably, the support elements are 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 un mode de réalisation particulier de l'invention, on réalise 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, on fixe des poutres d'appui sensiblement horizontales sur lesdits pieux, et on met en appui sur lesdites poutres les extrémités supérieures des éléments de soutènement. In a particular embodiment of the invention, substantially vertical piles are produced between the obstacles, for example in the form of sections of molded walls substantially perpendicular to the periphery of the structure, substantially horizontal support beams are fixed. on said piles, and the upper ends of the support elements are supported on said beams.

On décrira maintenant à titre d'exemple non limitatif un mode de réalisation particulier de l'invention en référence aux dessins annexés dans lesquels
- la figure 2 est une vue en demi-coupe transversale d'une étape d'un procédé selon l'invention,
- la figure 3 en est une demi-vue de dessus et,
- la figure 4 est une vue en coupe transversale de l'ouvrage terminé.
A particular embodiment of the invention will now be described by way of nonlimiting example with reference to the accompanying drawings in which
FIG. 2 is a view in half cross-section of a step of a method according to the invention,
- Figure 3 is a half view from above and,
- Figure 4 is a cross-sectional view of the finished work.

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 que l'on réalise entre les arbres 6 des barrettes 8 selon la technique bien connue des parois moulées. L'exécution de ces barrettes 8 est réalisée entre les arbres 6 de manière à ne pas les endommager et à ne pas intercepter leurs racines. If we refer to Figures 2 and 3 which show the same public road 4 lined with trees 6 as in Figure 1, we see that we realize between the trees 6 bars 8 according to the well-known technique of diaphragm walls . The execution of these bars 8 is carried out between the trees 6 so as not to damage them and not to intercept their roots.

Bien entendu, ces barrettes 8 pourraient être également réalisées de toute autre manière, par exemple, sous la forme de pieux forés, définitifs ou provisoires.  Of course, these bars 8 could also be produced in any other way, for example, in the form of bored piles, final or temporary.

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 bars 8 by any suitable means, for example by embedding or using metal inserts. These horizontal beams are for example produced in the form of concrete beams 9 as shown in FIG. 2, or in the form of metal beams 9 'as shown in FIG. 3.

On enfonce ensuite obliquement des éléments allongés par exemple des tubes métalliques de soutènement, 10 dans le terrain. En milieu urbain, l'enfoncement des tubes 10 est effectué par forage afin d'éviter tout choc ou vibration sur l'environnement. Then elongated elements are pushed obliquely, for example metal support tubes, 10 into the ground. In urban areas, the tubes 10 are driven in by drilling to avoid any impact or vibration on the environment.

On voit sur la figure 2 que les tubes 10 sont enfoncés tout le long de la périphérie de l'ouvrage, inclinés vers l'extérieur de celui-ci, et que leur extrémité supérieure est en appui sur les poutres horizontales 9. It can be seen in FIG. 2 that the tubes 10 are inserted all along the periphery of the structure, inclined towards the outside thereof, and that their upper end is in abutment on the horizontal beams 9.

La longueur des tubes 10 est telle qu'ils ne puissent endommager les fondations des immeubles riverains 5. The length of the tubes 10 is such that they cannot damage the foundations of the riverside buildings 5.

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 tubes 10 are also inserted so that they do not risk intercepting the hemisphere 7 of the roots of the trees 6.

On comprend que, lors du creusement ultérieur de l'ouvrage, le terrain situé au-dessus des tubes 10 sera 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 tubes 10 will be supported by the latter which are on the one hand embedded in the ground at their lower end and on the other hand resting on the beams 9 at their upper part.

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 souterrain 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 réalisés par les tubes 10. We can then pour the upper slab 2 of the structure, this slab possibly including the horizontal beams 9 and 9 ', then make the underground structure by any known means safe from this slab as shown in Figure 4, the earth and tree support 6 being produced by the tubes 10.

Un tel procédé permet par conséquent la libération quasi-totale de l'emprise de l'ouvrage, à l'exception des trémies d'accès au chantier. Such a process therefore 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.
