Description
La présente invention concerne la mise en place d'un dispositif de blocs de béton manufacturés spécifiques de coffrages perdus pour positionner des barbacanes de drainage en toute simplicité lors de l'édification des murs de soutènement.The present invention relates to the installation of a device of concrete blocks manufactured specific for lost formwork for positioning drainage barbicanes with ease during the construction of retaining walls.
Deux techniques sont actuellement employées pour poser des barbacanes de drainage. Elles consistent soit à découper les blocs à bancher ce qui les fragilisent, soit à percer le mur après sa réalisation. Dans les deux cas, la tâche de travail est longue, coûteuse et le résultat est irrégulier. On peut régulièrement constater l'absence de pente des barbacanes ou non homogènes et des diamètres de percements insuffisants ou au droit des armatures métalliques. L'existence de ces défaillances nuit à la résistance du mur de soutènement dans son ensemble.Two techniques are currently used to lay barbican drains. They consist either of cutting the blockwork which weakens them, or of drilling the wall after its completion. In both cases, the work task is long, expensive and the result is irregular. We can regularly see the absence of a slope for barbican or non-homogeneous and insufficient hole diameters or in line with the metal reinforcements. The existence of these failures affects the strength of the retaining wall as a whole.
Le dispositif selon l'invention a les avantages sur la première technique de gagner du temps en évitant la découpe d'un bloc standard, de ne pas le fragiliser en évitant de le découper, d'éviter que le passage de la barbacane se retrouve au droit des armatures métalliques, de maintenir une pente de la barbacane conforme au cahier des charges de construction et de ne pas avoir besoin de placer un coffrage complémentaire autour de la barbacane à créer.The device according to the invention has the advantages over the first technique of saving time by avoiding the cutting of a standard block, of not weakening it by avoiding cutting it, of preventing the passage of the barbican from being found in the right of the metal reinforcements, to maintain a slope of the barbican in accordance with the construction specifications and not to need to place an additional formwork around the barbican to be created.
Le dispositif selon l'invention permet de remédier aussi aux inconvénients de la deuxième technique qui consiste à percer le mur après sa réalisation. Les risques, outre le temps perdu à œuvrer, sont de percer au droit des armatures métalliques, de ne pas percer en respectant la pente de la barbacane conformément au cahier des charge ni de respecter les diamètres suffisants imposés pour l'évacuation des eaux.The device according to the invention also makes it possible to remedy the drawbacks of the second technique which consists in piercing the wall after its completion. The risks, in addition to the time lost in working, are to drill in line with the metal reinforcements, not to drill while respecting the slope of the barbican in accordance with the specifications, or of respecting the sufficient diameters imposed for the evacuation of water.
Pour remédier aux inconvénients ci-dessus évoqués, la présente invention vise à y pallier et propose de positionner un premier dispositif sur la rangée d'agglomérés à bancher existante avec la découpe semi-cylindrique sur la face supérieure, de poser la barbacane puis de placer un deuxième dispositif identique au premier renversé de manière à prendre en sandwich la barbacane cylindrique. Les deux éléments seront placés de telle sorte que le bas de la pente de la barbacane soit orienté vers l'extérieur du mur à édifier pour l'écoulement des eaux. L'ensemble des deux éléments posés l'un sur l'autre correspondra en dimensions à chaque autre aggloméré à bancher de façon à ce qu'il n'y ait aucune découpe à réaliser.To overcome the above-mentioned drawbacks, the present invention aims to alleviate it and proposes to position a first device on the row of agglomerates with existing shuttering with the semi-cylindrical cutout on the upper face, to lay the barbican then to place a second device identical to the first overturned so as to sandwich the cylindrical barbican. The two elements will be placed so that the bottom of the slope of the barbican is oriented towards the outside of the wall to be built for the flow of water. The set of two elements placed one on the other will correspond in size to each other agglomerate to be laid so that there is no cut to be made.
L'ensemble tel un coffrage perdu y compris la barbacane laissera l'espace réglementaire au passage du béton à couler, sans avoir à créer un coffrage spécifique complémentaire.The whole like a lost formwork including the barbican will leave the regulatory space for the passage of concrete to be poured, without having to create a specific additional formwork.
Selon des modes particuliers de réalisation le dispositif selon l'invention laissera un passage utile à la pose des armatures métalliques.According to particular embodiments, the device according to the invention will leave a useful passage for the installation of metal frames.
Les dessins annexés illustrent l'invention :The accompanying drawings illustrate the invention:

La figure 3 est une représentation de ia figure 2 les trois ensembles une fois assemblés.Figure 3 is a representation of Figure 2 the three sets once assembled.
La figure 4 est une coupe transversale qui montre la pente pour la barbacane et les espaces pour le passage des aciers des armatures.Figure 4 is a cross section showing the slope for the barbican and the spaces for the passage of reinforcing steel.
En référence à ces dessins, le dispositif comporte un premier élément (1) dont la face supérieure dispose d'un espace semi-cylindrique incliné permettant la pose d'un tube standard de drainage appelé barbacane. Ce dispositif est placé en quinconce sur une rangée inférieure de blocs de bétons à bancher et aligné sur ceux de sa rangée. L'élément est placé de façon à ce que l'ouverture semi-cylindrique se retrouve sur la face supérieure et le haut de la pente du demi-cylindre orienté vers le talus. Intervient la pose de la barbacane dont le diamètre extérieure coïncide avec l'ouverture semi-cylindrique. Un deuxième élément (2) est retourné face semi-cylindrique orienté vers le bas, la pente parallèle au premier élément, puis est posé sur le premier élément enfermant la barbacane. Les deux éléments empilés sont de hauteur égale à un bloc à bancher. L'opérateur peut placer les armatures en aciers sur toute sa rangée et remplir le vide du coffrage ainsi obtenu par du béton. Le dispositif ainsi réalisé permet le passage du béton à l'intérieur du mur mais l'empêche de se vider à l'extérieur de celui-ci. La barbacane tient un rôle de coffrage puis de drain.With reference to these drawings, the device comprises a first element (1), the upper face of which has an inclined semi-cylindrical space allowing the installation of a standard drainage tube called a barbican. This device is placed in staggered rows on a lower row of concrete block and aligned with those of its row. The element is placed so that the semi-cylindrical opening is found on the upper face and the top of the slope of the half-cylinder oriented towards the slope. The installation of the barbican takes place, the outside diameter of which coincides with the semi-cylindrical opening. A second element (2) is turned upside down, semi-cylindrical face, the slope parallel to the first element, then is placed on the first element enclosing the barbican. The two stacked elements are equal in height to a wall block. The operator can place the steel reinforcements over its entire row and fill the void of the formwork thus obtained with concrete. The device thus produced allows the passage of concrete inside the wall but prevents it from emptying outside of it. The barbican plays a role in formwork and then as a drain.
Le dispositif selon l'invention est particulièrement destiné aux drainages des murs de soutènement. Il sera réalisé par moulage industriel dans un coffrage mécanisé et respectera les normes en vigueurs sur la fabrication des blocs de bétons manufacturés. La présente invention n'est nullement limitée aux modes de réalisations décrits et représentés mais l'homme du métier saura y apporter toute variante conforme à son esprit.The device according to the invention is particularly intended for draining retaining walls. It will be produced by industrial molding in mechanized formwork and will comply with the standards in force on the manufacture of manufactured concrete blocks. The present invention is in no way limited to the embodiments described and shown, but a person skilled in the art will know how to make any variant which conforms to his spirit.
