Abstract

The method consists of marking out in the ground a working cavity in the shape of a parallelepiped using two pairs of trench shoring panels (2, 4) and placing formwork (7, 8) in it. The formwork (7, 8) is fixed relative to the shoring panels (2, 4) using centering stays (5) which bear firstly on the shoring panels (2, 4) and secondly on points of the formwork (7) that are uniformly distributed around its periphery. <IMAGE>

Description

La présente invention a pour objet un procédé de construction in situ d'une colonne creuse en béton destinée à être au moins partiellement enterrée et à servir, par exemple, de réservoir ou, une fois comblée, de fondation.The subject of the present invention is a method of in situ construction of a hollow concrete column intended to be at least partially buried and to serve, for example, as a reservoir or, once filled, as a foundation.

Jusqu'à présent, lorsque l'on désire réaliser une colonne creuse, destinée à être enterrée, on pratique une cavité dans le sol et on y enfonce des éléments de colonne préfabriqués qui s'emboîtent les uns au-dessus des autres. La descente des éléments dans la cavité est obtenue en tapant sur l'élément qui émerge de la cavité puis, lorsque celui-ci est suffisamment enfoncé, sur un nouvel élément rajouté à la pile et ainsi de suite.Until now, when it is desired to produce a hollow column intended to be buried, a cavity is practiced in the ground and prefabricated column elements which are inserted one above the other are inserted therein. The descent of the elements in the cavity is obtained by tapping on the element which emerges from the cavity then, when it is sufficiently pressed, on a new element added to the stack and so on.

L'inconvénient de ce système réside dans le fait qu'il arrive fréquemment que l'un des éléments se trouve bloqué dans sa descente, auquel cas il se sépare des éléments inférieurs et l'installateur n'a d'autre ressource que de descendre dans le puit formé par les éléments et de tenter de dégager l'élément bloqué. Cette opération est dangereuse car la pile supérieure d'éléments peut descendre brusquem- ment et blesser l'installateur. D'un autre côté, la chute brutale des éléments de la pile supérieure peut entraîner des dommages affectant les éléments eux-mêmes.The disadvantage of this system is that it often happens that one of the elements is blocked in its descent, in which case it separates from the lower elements and the installer has no other resource than to descend in the well formed by the elements and to try to free the blocked element. This operation is dangerous because the upper stack of elements can drop suddenly and injure the installer. On the other hand, the sudden fall of the cells in the upper stack can lead to damage affecting the cells themselves.

En outre, il est extrêmement difficile de réaliser, à l'aide de ce système connu, une colonne parfaitement verticale.In addition, it is extremely difficult to produce, using this known system, a perfectly vertical column.

En ce qui concerne la réalisation de fondations, à l'heure actuelle, on creuse le sol à l'aide d'une tarière ou d'un engin en remplissant simultanément la cavité d'une boue préparée en centrale. Ensuite, en utilisant un dispositif en forme d'entonnoir, on comble la cavité à l'aide de béton, à partir du fond, le béton chassant progressivement la boue vers le haut. L'inconvénient de ce procédé est que, à aucun moment, l'opérateur ne voit ce qui passe dans la cavité puisque celle-ci est constamment comblée et, donc, il n'a aucune assurance. quant à la qualité des fondations réalisées.With regard to the creation of foundations, at present, the soil is dug using an auger or a machine while simultaneously filling the cavity with mud prepared in the plant. Then, using a funnel-shaped device, the cavity is filled with concrete, starting from the bottom, the concrete gradually chasing the mud upwards. The disadvantage of this process is that, at no time, the operator does not see what is going into the cavity since it is constantly filled and, therefore, he has no insurance. as to the quality of the foundations made.

La présente invention a pour objet un procédé de construction qui est -utilisable aussi bien pour la réalisation d'un réservoir que pour celle de fondations et qui élimine les inconvénients précités.The subject of the present invention is a construction method which is usable as well for carrying out tion of a reservoir as for that of foundations and which eliminates the aforementioned drawbacks.

Ce procédé consiste à délimiter, dans le sol, une cavité de travail parallèlépipédique à l'aide de deux paires de panneaux de blindage de tranchées, à disposer dans ladite cavité un coffrage dont la forme et les dimensions correspondent à celles de la colonne attendue et à immobiliser ledit coffrage en position voulue par rapport aux panneaux de blindage à l'aide d'étaiements de centrage prenant appui, d'une part, sur les panneaux de blindage et, d'autre part, en des points régulièrement répartis de la périphérie du coffrage.This process consists in delimiting, in the ground, a parallelepipedal working cavity using two pairs of trench shielding panels, in placing in said cavity a formwork whose shape and dimensions correspond to those of the expected column and immobilizing said formwork in the desired position relative to the shielding panels by means of centering shoring bearing, on the one hand, on the shielding panels and, on the other hand, at regularly distributed points of the periphery formwork.

De préférence, des étaiements de centrage sont, en outre, régulièrement répartis sur la hauteur du coffrage.Preferably, centering shores are also regularly distributed over the height of the formwork.

De cette manière, il est permis d'immobiliser en position parfaitement verticale le coffrage de la colonne qui est construite sur place en coulant du béton dans ledit coffrage.In this way, it is allowed to immobilize in a perfectly vertical position the formwork of the column which is built on site by pouring concrete into said formwork.

De préférence, le coffrage est formé d'éléments de parois temporairement assemblés par des moyens amovibles.Preferably, the formwork is formed from wall elements temporarily assembled by removable means.

Des coffrages convenant pour la mise en oeuvre du procédé selon l'invention sont disponibles dans le commerce auprès de la société NOE - 78800 HOUILLES-FRANCE. Ces coffrages sont constitués de panneaux assemblés par bouton- clavettes que l'on peut désassembler par le bas au fur et à mesure que le béton est pris et réassembler par le haut pour couler une hauteur supplémentaire de colonne. De cette manière, il est possible de monter progressivement le coffrage et d'interrompre, à tout moment, le coulage du béton.Formwork suitable for implementing the method according to the invention is commercially available from the company NOE - 78800 HOUILLES-FRANCE. These forms are made up of panels assembled by button-keys which can be disassembled from below as the concrete is set and reassemble from the top to pour an additional column height. In this way, it is possible to progressively mount the formwork and stop, at any time, the pouring of the concrete.

La cavité de travail est avantageusement définie par une première paire parallèle de panneaux de blindage de tranchées à étaiement latéral et par une deuxième paire parallèle de panneaux de blindage de tranchées respectivement bloqués entre les extrémités de la première paire.The working cavity is advantageously defined by a first parallel pair of trench shielding panels with lateral shoring and by a second parallel pair of trench shielding panels respectively blocked between the ends of the first pair.

Comme leur nom l'indique, les panneaux de blindage de tranchées ont été conçus et utilisés jusqu'ici pour retenir les parois verticales de tranchées creusées, par exemple, pour la mise en place de canalisations. Selon l'invention, ils sont non seulement employés comme moyens de retenue de la terre, mais encore comme moyens de centrage d'un coffrage.As their name suggests, trench shielding panels have been designed and used to date to retain the vertical walls of dug trenches, for example, for the installation of pipes. According to the invention, they are not only used as means for retaining the earth, but also as means for centering a formwork.

Des panneaux de blindage appropriés sont disponibles dans le commerce auprès de la société ESBAU (Eckversheim 77750 VENDENHEIM-FRANCE).Appropriate shielding panels are commercially available from ESBAU (Eckversheim 77750 VENDENHEIM-FRANCE).

Les blindages de tranchées à étaiement latéral sont constitués par des panneaux parallèles réunis à leurs extrémités verticales opposées par des vérins dont la dilatation détermine la distance entre les panneaux et donc, dans l'application qui leur est donnée selon l'invention, la dimension de l'un des côtés de la cavité de travail.The lateral shoring trench shields are constituted by parallel panels joined at their vertical ends opposite by jacks whose expansion determines the distance between the panels and therefore, in the application given to them according to the invention, the dimension of one side of the working cavity.

Selon l'invention, cette première paire de panneaux de blindage de tranchées à étaiement latéral et la deuxième paire de panneaux de blindage de tranchées sont munis d'étaiements de centrage constitués par des vérins dont la tige est pourvue d'un galet qui prend appui sur le coffrage.According to the invention, this first pair of trench shielding panels with lateral shoring and the second pair of trench shielding panels are provided with centering shears constituted by jacks whose rod is provided with a roller which is supported on the formwork.

Le procédé selon l'invention est décrit ci-après en référence aux dessins annexés dans lesquels :

  • - la figure 1 représente une vue de dessus de la cavité de travail, avec le coffrage mis en place
  • - la figure 2 représente, en coupe et à plus grande échelle, la colonne obtenue par coulage de béton dans le coffrage de la figure 1
  • - la figure 3 représente, en coupe, un réservoir réalisé selon l'invention
  • - la figure 4 représente, en coupe, deux réservoirs concentriques réalisés selon l'invention, et
  • - la figure 5 illustre schématiquement l'utilisation du double réservoir représentée à la figure 4 comme accumulateur d'énergie.
The method according to the invention is described below with reference to the accompanying drawings in which:
  • - Figure 1 shows a top view of the working cavity, with the formwork in place
  • - Figure 2 shows, in section and on a larger scale, the column obtained by pouring concrete into the formwork of Figure 1
  • - Figure 3 shows, in section, a tank made according to the invention
  • FIG. 4 represents, in section, two concentric tanks produced according to the invention, and
  • - Figure 5 schematically illustrates the use of the double tank shown in Figure 4 as an energy accumulator.

Si l'on se réfère à la figure 1, on voit, mis en place dans le sol 1, deux panneaux de blindage de tranchées 2 à étaiement latéral, c'est-à-dire dont l'écartement est réglé par des vérins 3 disposés au voisinage des extrémités opposées de ces panneaux 2. Pour la mise en place de ce panneau 2, on a soit creusé une fouille de dimensions appropriées à l'aide d'un engin, puis descendu le blindage dans la fouille après quoi l'on a écarté les panneaux 2 en dilatant les vérins 3, soit enfoncé progressivement les panneaux 2 à l'aide du godet d'une pelle tout en continuant de creuser entre eux. La technique choisie dépend de la nature du sol.Referring to Figure 1, we see, set up in the ground 1, two trench shielding panels 2 with lateral shoring, that is to say whose spacing is adjusted by jacks 3 arranged in the vicinity of the opposite ends of these panels 2. For the installation of this panel 2, an excavation of dimensions was either dug appropriate using a machine, then lower the shielding into the excavation after which the panels 2 have been spread by expanding the jacks 3, or gradually push the panels 2 using the bucket of a shovel while continuing to dig between them. The technique chosen depends on the nature of the soil.

Entre les panneaux 2, sont coincés des panneaux de blindage de tranchées 4. Les panneaux 2 et 4 sont, en outre, pourvus d'une succession verticale de vérins centraux 5 dont la tige est munie, à son extrémité opposée aux panneaux, d'un galet 6. Un coffrage circulaire formé d'une paroi extérieure 7 et d'une paroi intérieure 8 est disposé dans la cavité de travail délimitée par les panneaux 2 et 4. Ce coffrage 7, 8, qui de, préférence, n'a pas un diamètre intérieur inférieur à 1,50 m, est immobilisé en position verticale en règlant convenablement les vérins 5 dont le galet 6 prend appui sur la paroi 7.Between the panels 2, trench shielding panels 4 are trapped. The panels 2 and 4 are, moreover, provided with a vertical succession of central jacks 5, the rod of which is provided, at its end opposite to the panels, with a roller 6. A circular formwork formed by an outer wall 7 and an inner wall 8 is disposed in the working cavity delimited by the panels 2 and 4. This formwork 7, 8, which preferably has no not an inner diameter less than 1.50 m, is immobilized in a vertical position by properly adjusting the jacks 5, the roller 6 of which rests on the wall 7.

Les parois 7 et 8 du coffrage sont chacune composées d'éléments de parois 7' et 8' comportant des brides de montage au travers desquelles est passé un bouton-clavette 27. Il est bien entendu que, sur la figure 1, la taille des brides a été exagérée à des fins d'illustration et que, dans la réalité, ces brides 27 ne font pas saillie hors du gabarit général des éléments de parois 7' et 8'. Un homme peut donc descendre dans le puits déterminé par la paroi 8 sans risque de se blésser.The walls 7 and 8 of the formwork are each composed of wall elements 7 ′ and 8 ′ having mounting flanges through which a key button 27 has passed. It is understood that, in FIG. 1, the size of the flanges has been exaggerated for purposes of illustration and that, in reality, these flanges 27 do not protrude outside the general gauge of the wall elements 7 ′ and 8 ′. A man can therefore descend into the well determined by the wall 8 without risk of being injured.

Par ferraillage puis coulage de béton entre les parois 7 et 8, on obtient une colonne creuse 9 représentée à la figure 2.By reinforcing and then pouring concrete between the walls 7 and 8, a hollow column 9 is shown, shown in FIG. 2.

Une fois le coulage terminé et le béton pris, on rétracte les vérins 5, enlève le coffrage 7, 8, dégage les panneaux 4 en dilatant les vérins 3 puis enlève les panneaux 2. On comble ensuite de terre la cavité de travail..Once the pouring is complete and the concrete has set, the cylinders 5 are retracted, the formwork 7, 8 is removed, the panels 4 are released by expanding the cylinders 3 and then the panels are removed 2. The working cavity is then filled with earth.

Cette colonne 9 peut servir à la réalisation de fondations, auquel cas elle sera comblée à l'aide de matériaux appropriés, ou à la réalisation d'un réservoir par exemple du réservoir isolé représenté à la figure 3.This column 9 can be used for making foundations, in which case it will be filled with suitable materials, or for making a tank, for example the insulated tank shown in FIG. 3.

A la figure 3, on retrouve la colonne en béton 9, une couche d'isolation 10 et un tuyau en acier ou en fonte 11. Un tel réservoir peut être utilisé comme accumulateur d'énergie.In Figure 3, we find the concrete column 9, a insulation layer 10 and a steel or cast iron pipe 11. Such a tank can be used as an energy accumulator.

La figure 4 représente la même structure que la figure 3, à cela près qu'à l'intérieur du tuyau 11 se trouve un second tuyau en acier ou en fonte 12. La colonne 9 renferme donc deux réservoirs concentriques. Un exemple d'application du réservoir de la figure 4 est représenté à la figure 5.Figure 4 shows the same structure as Figure 3, except that inside the pipe 11 is a second steel or cast iron pipe 12. The column 9 therefore contains two concentric tanks. An example of application of the reservoir of FIG. 4 is shown in FIG. 5.

Dans cette figure, où le double réservoir peut avoir une profondeur de 10 mètres ou plus, le réservoir extérieur 13 renferme de l'eau à une température inférieure à celle de l'eau qui est contenue dans le réservoir intérieur 14. Plus précisemment, l'eau extraite du réservoir 13 selon la conduite 15, et complétée éventuellement en volume par l'arrivée d'eau 16, est chauffée, par exemple, par un chauffe-eau solaire 17 et une cheminée 18 munie d'un récupérateur de chaleur. L'eau rechauffée est acheminée par la conduite 19 dans le réservoir intérieur 14 d'où elle est soutirée selon la conduite 20 pour circuler dans des radiateurs de chauffage central 21. Des radiateurs 21 l'eau revient dans le réservoir extérieur 13 selon la conduite 22. Comme on le voit, le réservoir intérieur 14 sert également à' rechauffer de l'eau à usage domestique provenant de l'arrivée 16 et acheminée par la conduite 23 dans un serpentin 24 qui plonge dans le réservoir 14 et qui est raccordé par la conduite 25 à une station de chauffage complémentaire ou à un poste d'utilisation 26.In this figure, where the double tank can have a depth of 10 meters or more, the external tank 13 contains water at a temperature lower than that of the water which is contained in the internal tank 14. More precisely, l 'water extracted from the reservoir 13 along line 15, and possibly supplemented in volume by the supply of water 16, is heated, for example, by a solar water heater 17 and a chimney 18 provided with a heat recovery unit. The heated water is routed through line 19 into the internal tank 14 from where it is drawn off along line 20 to circulate in central heating radiators 21. From radiators 21 the water returns to the external tank 13 along line 22. As can be seen, the internal tank 14 also serves to 'heat water for domestic use coming from the inlet 16 and conveyed by line 23 in a coil 24 which plunges into the tank 14 and which is connected by the pipe 25 to an additional heating station or to a user station 26.

Il est bien entendu que l'invention n'est pas limitée au mode de mise en oeuvre et aux applications décrites ci-dessus. En particulier, dans l'application ci-dessus, les réservoirs 13 et 14 pourraient être indépendants. Par ailleurs, le procédé pourrait servir à la réalisation de réserve d'eau pompée à des fins d'irrigation ou à la construction de puits.It is understood that the invention is not limited to the mode of implementation and to the applications described above. In particular, in the above application, the reservoirs 13 and 14 could be independent. Furthermore, the process could be used to create a reserve of pumped water for irrigation purposes or to build wells.
