Description
Dispositif d'avertissement et de protection de conduites Warning and protection device for pipes
ou câbles enterrés or buried cables
La présente invention concerne un dispositif d'avertissement et de protection de conduites ou câbles enterrés. The present invention relates to a warning device and protection of buried pipes or cables.
Afin d'éviter la dégradation de conduites ou câbles enterrés lors de travaux de terrassement, il est connu d'utiliser des dispositifs d'avertissement et de protection noyés dans la terre et disposés au-dessus des conduites ou câbles enterrés. In order to avoid the degradation of pipes or cables buried during earthworks, it is known to use warning and protection devices embedded in the earth and disposed above buried pipes or cables.
Ces dispositifs de protection permettent d'une part de protéger les conduites ou câbles enterrés contre des détériorations causées par le godet d'une pelle mécanique, et d'autre part d'avertir l'opérateur de la présence de condu ites ou câbles de manière à ce que ce dernier ne creuse pas plus profondément à cet endroit. These protection devices make it possible, on the one hand, to protect underground pipes or cables against damage caused by the bucket of a shovel, and on the other hand to warn the operator of the presence of pipes or cables in such a way that that the latter does not dig deeper into this place.
Un premier type de dispositif d'avertissement et de protection connu consiste en une plaque de protection en béton armé. Ce type de dispositif de protection présente une résistance mécanique suffisante pour protéger des conduites ou câbles enterrés contre des détériorations causées par le godet d'une pelle mécanique. A first type of known warning and protection device consists of a reinforced concrete protection plate. This type of protection device has sufficient mechanical strength to protect underground pipes or cables against damage caused by the bucket of a shovel.
Toutefois, un premier inconvénient d'une telle plaque de protection réside en ce qu'elle est lourde et encombrante, ce qui a pour conséquence de rendre cette dernière difficilement manipulable. Un second inconvénient d'une telle plaque de protection réside en ce qu'elle favorise la retenue des eaux souterraines, ce qui peut conduire à des glissements de terrain. However, a first disadvantage of such a protection plate is that it is heavy and bulky, which has the effect of making the latter difficult to manipulate. A second disadvantage of such a protective plate is that it promotes the retention of groundwater, which can lead to landslides.
De plus, les armatures métall iques incorporées dans une telle plaque de protection en béton armé peuvent parasiter les signaux électriques ou électromagnétiques émis par un dispositif de détection et d'identification d'éléments enterrés, et donc empêcher un repérage satisfaisant de la conduite enterrée par un opérateur. Il en résulte des risques de détérioration de la conduite enterrée lors de travaux de terrassement ultérieurs. In addition, the metal reinforcements incorporated in such a reinforced concrete protection plate can parasitize the electrical or electromagnetic signals emitted by a device for detecting and identifying buried elements, and thus prevent a satisfactory identification of the buried pipe by an operator. This results in risks of deterioration of the buried pipe during subsequent earthworks.
Un second type de dispositif d'avertissement et de protection connu, tel que décrit dans le document US 4 242 010, comprend une pluralité de plaques de protection en béton s'étendant transversalement à la direction de pose du dispositif, et des câbles de liaison s'étendant dans la direction de pose du dispositif, les câbles étant agencés pour coopérer avec une pluralité de plaques de protection de manière à relier ces dernières entre elles. Un tel dispositif de protection présente sensiblement les mêmes inconvénients que le dispositif de protection précédemment décrit. A second type of known warning and protection device, as described in US Pat. No. 4,242,010, comprises a plurality of concrete protection plates extending transversely to the laying direction of the device, and connecting cables. extending in the laying direction of the device, the cables being arranged to cooperate with a plurality of protection plates so as to connect the latter together. Such protection device has substantially the same disadvantages as the protection device described above.
Un troisième type de dispositif d'avertissement et de protection connu consiste en un grillage avertisseur destiné à être déroulé au-dessus des conduites ou câbles enterrés. Un tel grillage avertisseur est facilement manipulable et favorise l'évacuation des eaux souterraines, mais présente cependant une résistance mécanique insuffisante pour protéger de manière sécurisée les conduites ou câbles enterrés contre des détériorations causées par le godet d'une pelle mécanique. A third type of known warning and protection device consists of a warning grid intended to be unrolled over buried pipes or cables. Such a warning mesh is easily manipulated and promotes the evacuation of groundwater, but has, however, insufficient mechanical strength to securely protect underground pipes or cables against damage caused by the bucket of a digger.
La présente invention vise à remédier à ces inconvénients. The present invention aims to remedy these disadvantages.
Le problème technique à la base de l'invention consiste donc à fournir un dispositif d'avertissement et de protection de conduites ou câbles enterrés qui soit de structure simple, économique, résistante et légère, tout en diminuant les risques de glissement de terrain. The technical problem underlying the invention therefore consists in providing a warning and protection device for underground pipes or cables which is simple in structure, economical, resistant and light, while reducing the risk of landslides.
A c e t effe t , la présente invention concerne un dispositif d'avertissement et de protection de conduites ou câbles enterrés, comprenant une pluralité de plaques de protection s'étendant transversalement à la direction d e pose d u d ispos itif, et d es moyens de liaison s'étendant sensiblement dans la direction de pose du dispositif, les moyens de liaison étant agencés pour coopérer avec une pluralité de plaques de protection de manière à relier ces dernières entre elles, caractérisé en ce que chaque plaque de protection comporte une pluralité d'orifices traversants débouchant respectivement dans une première et une seconde faces de ladite plaque de protection. To this end, the present invention relates to a device for warning and protection of buried pipes or cables, comprising a plurality of protection plates extending transversely to the laying direction of the device, and connecting means extending substantially in the laying direction of the device, the connecting means being arranged to cooperate with a plurality of protection plates so as to connect the latter together, characterized in that each protection plate comprises a plurality of through holes opening respectively in a first and a second faces of said protection plate.
La présence des orifices traversants permet l'évacuation des eaux souterraines à travers chaque plaque de protection, ce qui diminue les risques de glissement de terrain. The presence of the through holes allows the evacuation of groundwater through each protection plate, which reduces the risk of landslide.
De plus, la présence des orifices traversants facilite le passage des signaux électriques ou électromagnétiques émis par un dispositif de détection et d'identification, donc améliore la localisation des conduites et/ou câbles enterrés. In addition, the presence of the through holes facilitates the passage of electrical or electromagnetic signals emitted by a detection and identification device, thus improving the location of pipes and / or buried cables.
En outre, lorsque le dispositif d'avertissement et de protection recouvre des conduites de gaz, la présence des orifices traversants empêche une accumulation de gaz sous les plaques de protection en cas de fuite. In addition, when the warning and protection device covers gas lines, the presence of the through holes prevents gas accumulation under the protective plates in case of leakage.
La présence de tels moyens de liaison permet d'augmenter la résistance à l'arrachement du dispositif selon l'invention, et donc d'améliorer la protection mécanique des conduites ou câbles enterrés contre des détériorations causées par le godet d'une pelle mécanique. The presence of such connecting means makes it possible to increase the tear resistance of the device according to the invention, and therefore to improve the mechanical protection of underground pipes or cables against damage caused by the bucket of a digger.
Avantageusement, chaque plaque de protection est réalisée en matière synthétique en une seule pièce. Advantageously, each protection plate is made of synthetic material in one piece.
L'utilisation de matière synthétique pour réaliser chaque plaque de protection permet d'obtenir un dispositif d'avertissement et de protection de faible poids et donc facilement manipulable. De plus, l'utilisation de matière synthétique permet de réaliser chaque plaque de protection par moulage et donc d'obtenir des coûts de fabrication très faibles. The use of synthetic material to make each protection plate provides a warning device and protection of low weight and therefore easy to handle. In addition, the use of synthetic material makes it possible to produce each protection plate by molding and thus to obtain very low manufacturing costs.
En outre, le fait que chaque plaque de protection soit réalisée en matière synthétique permet de ne pas parasiter les signaux électriques ou électromagnétiques émis par un dispositif de détection et d'identification d'éléments enterrés, et donc de ne pas compromettre la détection et le repérage des conduites enterrées. In addition, the fact that each protective plate is made of synthetic material makes it possible not to interfere with the electrical or electromagnetic signals emitted by a device for detecting and identifying buried elements, and thus not to compromise the detection and identification of buried pipes.
Le fait que chaque plaque de protection soit réalisée en matière synthétique permet également d'obtenir, en utilisant une matière synthétique appropriée, un dispositif d'avertissement et de protection de couleur vive. Un tel dispositif formera, de par sa coloration vive, un moyen d'avertissement visuel pour un opérateur lors de travaux de terrassement. De ce fait, il n'est plus nécessaire de prévoir des systèmes d'avertissement complémentaires du type grillage avertisseur, ce qui permet de réduire les coûts de protection des conduites ou câbles enterrés. The fact that each protective plate is made of synthetic material also makes it possible to obtain, using a suitable synthetic material, a brightly colored warning and protection device. Such a device will form, by its bright color, a visual warning means for an operator during earthworks. As a result, it is no longer necessary to provide warning systems complementary to the warning mesh type, which makes it possible to reduce the costs of protecting buried pipes or cables.
De préférence, les moyens de liaison comportent au moins une sangle de renforcement, et par exemple trois sangles de renforcement. Preferably, the connecting means comprise at least one reinforcing strap, and for example three reinforcing straps.
Selon un premier mode de réalisation de l'invention, les plaques de protection sont espacées les unes des autres et sont surmoulées sur la ou les sangles de renforcement. Ces dispositions permettent, lorsque le dispositif com porte u ne pl u ra l ité d e sang l e de renforcement, de garantir le positionnement et l'écartement des sangles. According to a first embodiment of the invention, the protection plates are spaced from each other and are overmolded on the reinforcing strap or straps. These arrangements make it possible, when the device comprises a maximum of reinforcing blood, to guarantee the positioning and spacing of the straps.
Selon un second mode de réalisation de l'invention, chaque plaque de protection est sensiblement rectangulaire et présente des premiers moyens d'assemblage ménagés au niveau de l'un de ses bords longitudinaux et des seconds moyens d'assemblages, complémentaires des premiers moyens d'assemblage, ménagés au niveau de son autre bord longitudinal, les seconds moyens d'assemblage d'une plaque de protection étant destinés à coopérer avec les premiers moyens d'assemblage d'une plaque de protection adjacente. De façon avantageuse, les premiers et seconds moyens d'assemblage sont conçus pour autoriser une articulation entre deux plaques de protection adjacentes autour d'un axe sensiblement parallèle aux bords longitudinaux desdites plaques de protection. According to a second embodiment of the invention, each protection plate is substantially rectangular and has first assembly means formed at one of its longitudinal edges and second assembly means, complementary to the first means of assembly. assembly, formed at its other longitudinal edge, the second assembly means of a protective plate being intended to cooperate with the first assembly means of an adjacent protective plate. Advantageously, the first and second assembly means are designed to allow articulation between two adjacent protection plates around an axis substantially parallel to the longitudinal edges of said protection plates.
Préférentiellement, les premiers moyens d'assemblage comportent au moins une portion sensiblement cylindrique s'étendant sensiblement parallèlement aux bords longitudinaux de la plaque de protection correspondante, et les seconds moyens d'assemblage comportent au moins une portion formant crochet présentant une forme au moins partiellement complémentaire de celle de ladite portion sensiblement cylindrique. Preferably, the first assembly means comprise at least one substantially cylindrical portion extending substantially parallel to the longitudinal edges of the corresponding protection plate, and the second assembly means comprise at least one hook portion having a shape at least partially complementary to that of said substantially cylindrical portion.
Avantageusement, l a ou chaque sangle de renforcement est entrelacée avec une pluralité de plaques de protection de manière à être disposée alternativement au dessus et en dessous des plaques de protection. Advantageously, the or each reinforcing strap is interlaced with a plurality of protection plates so as to be arranged alternately above and below the protective plates.
Les moyens de l iaison comportent de préférence des moyens d'identification des conduites ou câbles enterrés, les moyens d'indentification étant de préférence des inscriptions imprimées. Les inscriptions peuvent être par exemple du type « gaz », "attention gaz" ou "gaz haute pression". The means of the iaison preferably comprise means of identification of buried pipes or cables, the means of identification being preferably printed inscriptions. The inscriptions may for example be of the "gas", "gas attention" or "high pressure gas" type.
De façon préférentielle, au moins l'une des première et seconde faces de chaque plaque de protection comporte, sur au moins une partie de sa surface, des saillies, telles que des nervures. La présence de saillies sur au moins l'une des faces de chaque plaque de protection améliore la tenue de ladite plaque, notamment au fond de la tranchée destinée à recevoir cette dernière, et diminue encore les risques de glissement de terrain. Preferably, at least one of the first and second faces of each protective plate has, on at least a portion of its surface, projections, such as ribs. The presence of projections on at least one of the faces of each protective plate improves the holding of said plate, particularly at the bottom of the trench intended to receive the latter, and further reduces the risk of landslide.
De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, deux formes d'exécution de ce dispositif d'avertissement et de protection.
