DISPOSITIF DE RECOUVREMENT TEMPORAIRE POUR REGARD DE TEMPORARY RECOVERY DEVICE FOR LOOKING

CHAUSSEE, ET OUTIL POUR SA MANIPULATION. Domaine technique.CHAUSSEE, AND TOOL FOR HANDLING. Technical area.

La présente invention est du domaine des matériels utilisés lors des travaux de réfection des voiries et a pour objet un dispositif de recouvrement et de protection pour regards de chaussée. Par regard de chaussée, on entend des regards de vanne d'alimentation en eau du domicile d'un abonné à partir du réseau urbain de distribution d'eau, des regards de visite, des bouches avec grilles amovibles d'évacuation d'eau, et plus généralement tous types de regards comportant un couvercle amovible. La présente invention à également pour objet un outil pour la manipulation du dispositif de recouvrement temporaire selon l'invention, ainsi q'un chapeau permettant l'exécution des revêtements en enrobé à chaud. État de la technique.The present invention is in the field of equipment used during road repairs and has for object a cover and protection device for manholes. By "manhole" is meant water supply valve manholes of a subscriber's home from the urban water distribution network, manholes, vents with removable drainage grilles, and more generally all types of eyes having a removable cover. The present invention also relates to a tool for handling the temporary covering device according to the invention, as well as a cap for the execution of coatings hot mix. State of the art

Les regards de chaussée sont traditionnellement de forme cylindrique ou parallélépipédique et sont disposés dans le massif d'une voie de circulation publique. Ces regards sont obturés en partie supérieure par des couvercles métalliques amovibles, ces couvercles dans le cas d'une bouche d'évacuation d'eau prennent alors la forme d'une grille.The manholes are traditionally cylindrical or parallelepipedic and are arranged in the mass of a public road. These eyes are closed at the top by removable metal covers, these covers in the case of a water outlet mouth then take the form of a grid.

Certains de ces regards connus sous le terme de bouche à clé sont destinés à abriter chacun une vanne d'arrêt installée sur la conduite d'alimentation en eau établie entre le réseau urbain de distribution d'eau et le compteur totalisateur équipant le domicile de l'abonné. Il faut savoir que cette vanne est le seul élément d'arrêt d'urgence accessible depuis l'extérieur du domicile de l'abonné par les préposés à l'entretien et à la surveillance du réseau de distribution. Ainsi en cas de sinistre dans le domicile de l'abonné, comme par exemple une rupture de canalisation, l'alimentation en eau peut être coupée rapidement. Divulgation de l'invention. Problème technique.Some of these looks known as the keyhole are intended to each house a shutoff valve installed on the water supply line established between the urban water distribution network and the totalizer meter equipping the home of the 'subscriber. It should be noted that this valve is the only emergency stop accessible from outside the subscriber's home by the service and maintenance staff of the distribution network. Thus in the event of a disaster in the home of the subscriber, such as for example a broken line, the water supply can be cut quickly. Disclosure of the invention. Technical problem.

Actuellement, lors des travaux de réfection du revêtement bitumineux de la chaussée, les regards de chaussée comme les bouches à clé, avant épandage des matériaux de revêtement sont recouverts d'une couche de sable de protection pour éviter les infiltrations de bitume dans l'interstice entre le corps du regard et le couvercle ce qui conduirait au scellement de ce dernier. La surépaisseur que constitue cette couche de sable disparaît lors des travaux de cylindrage de la masse bitumineuse épandue, de sorte qu'il n'est plus possible de distinguer par la suite l'emplacement exact du regard. La nécessité de rendre accessible le couvercle et le regard conduit l'homme de l'art à rechercher l'emplacement du regard à l'aide de détecteurs de métaux et ensuite à casser la couche bitumineuse qui recouvre le couvercle. Bien souvent cette opération doit être complétée par des travaux de réfection de l'abord du regard.Currently, during the repair of pavement asphalt pavement, manholes and keyholes, before spreading coating materials are covered with a layer of protective sand to prevent infiltration of bitumen into the interstice between the body of the gaze and the lid which would lead to the sealing of the latter. The extra thickness that constitutes this layer of sand disappears during the work of rolling of the bituminous mass spread, so that it is no longer possible to distinguish the exact location of the gaze. The need to make the cover and the eye accessible makes those skilled in the art look for the location of the gaze using metal detectors and then break the bituminous layer covering the lid. Often this operation must be supplemented by work to repair the look of the eye.

Ces diverses opérations qui doivent être répétées autant de fois, que de regards que comporte la chaussée en réfection, engendrent d'importantes pertes de temps et des surcoûts notables. Solution technique.These various operations, which must be repeated as many times as the looks of the pavement being repaired, entail significant time losses and significant additional costs. Technical solution.

La présente invention vise à résoudre les problèmes sus évoqués en mettant en œuvre un dispositif de recouvrement temporaire de regard de chaussée notamment de bouche à clé permettant le repérage facile de l'emplacement de la bouche à clé. Un autre but de la présente invention est la suppression de tous travaux de dégagement du regard de chaussée une fois le revêtement bitumineux effectué.The present invention aims to solve the aforementioned problems by implementing a temporary covering system for pavement look including key-tapping for easy identification of the location of the key-way. Another object of the present invention is the removal of all clearance work of the manhole once the bituminous coating is carried out.

Un autre but de la présente invention est la suppression de tous travaux de dégagement du regard de chaussée une fois le revêtement bitumineux effectué.Another object of the present invention is the removal of all clearance work of the manhole once the bituminous coating is carried out.

Un autre but de la présente invention est la suppression des travaux de réfection des abords du regard de chaussée.Another object of the present invention is the removal of repair work around the eyes of the roadway.

À cet effet le dispositif de recouvrement temporaire et de protection pour regard de chaussée utilisable notamment pour recouvrir et protéger regard des projections de produits et matériaux de revêtement de chaussée lors des travaux de réfection du revêtement de la chaussée, le regard de chaussée comprenant un corps de regard, de forme tubulaire, engagé verticalement dans le massif de la chaussée et un couvercle d'obturation engagé de manière amovible dans un logement formé en partie supérieure du corps du regard afin d'obturer ce dernier se caractérise essentiellement en ce qu'il est constitué d'un fut tubulaire vertical obturé en partie inférieure et ouvert en partie supérieure destiné à être engagé dans le corps de regard, ledit fût comportant en partie supérieure autour de l'orifice présent à ce niveau, une collerette périphérique destinée à venir en appui contre la rive supérieure du corps de regard.For this purpose the temporary covering device and protection for view of roadway used in particular to cover and protect the projections of products and pavement materials during the repair work of the pavement, the manhole comprising a body view, of tubular form, engaged vertically in the solid mass of the roadway and a shutter cover removably engaged in a housing formed in the upper part of the body of the eye to close the latter is characterized essentially in that it consists of a vertical tubular tube closed in the lower part and open at the top to be engaged in the body of view, said barrel having in the upper part around the orifice present at this level, a peripheral collar intended to come into support against the upper bank of the body of gaze.

Avant travaux de réfection de la chaussée, il suffit de retirer le couvercle d'obturation du regard et d'introduire dans cette dernière le dispositif selon l'invention, la collerette de ce dernier venant en appui contre la rive supérieure du corps du regard. Lors des travaux de gravillonnage et bitumage, les projections de matière sont reçues par le fut qui constitue alors panier de rétention. Le volume de matériaux déposés au niveau du regard de chaussée n'est pas suffisant pour remplir le fût du dispositif selon l'invention de sorte que l'emplacement du regard de chaussée demeure toujours visible même après travaux de cylindrage. Il suffira ensuite, avant durcissement de la couche bitumineuse de retirer le dispositif de protection pour dégager le regard de chaussée et ensuite de replacer le couvercle d'obturation.Before repairing the roadway, all that is required is to remove the shutter cover from the viewer and to introduce into the latter the device according to the invention, the collar of the latter bearing against the upper side of the body of the gaze. During the graveling and asphalting operations, the material projections are received by the drum, which then constitutes a retention basket. The volume of material deposited at the level of the manhole is not sufficient to fill the shaft of the device according to the invention so that the location of the manhole is still visible even after rolling work. It will suffice then, before hardening of the bituminous layer to remove the protective device to clear the manhole and then to replace the cover shutter.

Selon une autre caractéristique de l'invention, le fut est tronconique et s'élargit progressivement depuis son extrémité inférieure vers son extrémité supérieure.According to another characteristic of the invention, it is frustoconical and widens progressively from its lower end to its upper end.

Une telle disposition vise à faciliter l'introduction du dispositif dans le corps regard et également d'en faciliter son retrait ultérieur.Such an arrangement is intended to facilitate the introduction of the device into the body of vision and also to facilitate its subsequent withdrawal.

Selon encore une autre caractéristique de l'invention, le fut une fois en place dans le corps du regard demeure écarté radialement de la paroi interne de ce dernier. Cette disposition à également pour but de faciliter le retrait du dispositif à l'aide d'un outil approprié.According to yet another feature of the invention, once was in place in the body of the gaze remains radially spaced from the inner wall of the latter. This provision is also intended to facilitate removal of the device using a suitable tool.

Selon encore une autre caractéristique de l'invention, le chapeau est positionné sur le cône pour la réalisation de revêtements en enrobé.According to yet another characteristic of the invention, the cap is positioned on the cone for producing asphalt coatings.

Préférentiellement pour en réduire le coût, le dispositif est réalisé en matière synthétique.Preferably to reduce the cost, the device is made of synthetic material.

La présente invention à également pour objet un outil de manipulation du dispositif selon l'invention. Cet outil est remarquable notamment en ce qu'il comprend une poignée de manœuvre auquel est fixé un guide tubulaire vertical comportant à l'opposé de la poignée un guide tubulaire horizontal dans lequel est montée en coulissement au moins une aiguille de perforation et de préhension actionnée par un mécanisme de manœuvre à came monté dans un guide tubulaire vertical et pénétrant dans le guide tubulaire horizontal ce mécanisme de manœuvre comportant un bouton de manœuvre monté sur la poignée par action sur lequel le mécanisme de manœuvre actionne l'aiguille d'une position rétractée dans le guide horizontal vers une position déployée en dehors du guide selon laquelle elle perfore le fût du dispositif de recouvrement. Avantages apportés. On comprend que grâce à l'emploi du dispositif de recouvrement temporaire selon l'invention sont supprimés tous les travaux de recherche et de dégagement du regard de chaussée conduisant à des surcoûts notables. Brève description des dessins. - la figure 1 est une vue en coupe longitudinale d'un regard de chaussée par exemple d'une bouche à clé.The present invention also relates to a tool for handling the device according to the invention. This tool is remarkable in that it comprises a handle which is attached to a vertical tubular guide having opposite to the handle a horizontal tubular guide in which is slidably mounted at least one perforation needle and gripping actuated by a cam actuation mechanism mounted in a vertical tubular guide and penetrating the horizontal tubular guide this operating mechanism comprising an operating knob mounted on the handle by action on which the operating mechanism actuates the needle of a retracted position in the horizontal guide to a deployed position outside the guide according to which it perforates the barrel of the covering device. Benefits brought.

Meilleur mode de réalisation de l'invention. En figure 1 est représentée un regard de chaussée par exemple une bouche à clé 1 avec son couvercle d'obturation 2. On peut voir sur cette figure que la bouche à clé est constituée par un corps de regard 3 tubulaire engagé verticalement dans le massif de la chaussée. Habituellement ce corps est cylindrique, mais il peut être parallélépipédique.Best embodiment of the invention. In FIG. 1 is shown a manhole, for example a key-fob 1 with its shutter cover 2. It can be seen in this figure that the key-fob is constituted by a tubular-looking body 3 which is vertically engaged in the pavement. Usually this body is cylindrical, but it can be parallelepipedic.

Ce corps comporte en partie supérieure un logement sous forme d'évasement tronconique 3 a dans lequel est introduit le couvercle 2 du regard de chaussée. Cette bouche à clé protège une vanne d'arrêt 4 installée sur une conduite 5 d'alimentation en eau raccordée d'une part au réseau urbain de distribution d'eau et d'autre part au compteur totalisateur de l'abonné au service de distribution d'eau.This body comprises in the upper part a housing in the form of frustoconical flare 3 in which is introduced the lid 2 of the manhole. This key-lock protects a shutoff valve 4 installed on a water supply pipe 5 connected on the one hand to the urban water distribution network and on the other hand to the totalizing meter of the subscriber to the distribution service. of water.

En figure 2 est représenté un dispositif de protection 6 selon l'invention. Comme on peut le voir ce dispositif, réalisé par exemple en matière synthétique, comprend un fût tronconique 7 obturé en partie inférieur par une paroi de fond 8, constituant un panier étanche de rétention. Le fut est pourvu en partie supérieure d'une collerette périphérique 9 d'appui, de forme circulaire par exemple.FIG. 2 shows a protection device 6 according to the invention. As can be seen this device, made for example of synthetic material, comprises a frustoconical barrel 7 closed in the lower part by a bottom wall 8, constituting a sealed retaining basket. The fut is provided in the upper part of a peripheral flange 9 support, circular shape for example.

Préférentiellement, le fut 7 du dispositif de recouvrement 6 s'élargit progressivement depuis la paroi de fond 8 vers la collerette 9. Cette disposition a pour effet de faciliter la mise en place du fût dans le regard de chaussée et aussi comme on le verra plus loin d'en faciliter sa préhension et son retrait à l'aide de l'outil dédié.Preferably, the 7 of the covering device 6 widens progressively from the bottom wall 8 to the flange 9. This provision has the effect of facilitating the establishment of the barrel in the eyes of the road and also as we will see more far from facilitating its grip and withdrawal with the help of the dedicated tool.

Comme on peut le voir en figure 3, le dispositif de protection 6 est engagé par son fût 7 dans le corps de regard 3 et vient en appui par la face inférieure de la collerette 9 sur la rive supérieure du corps de regard. Le fut 7 du dispositif de protection 6 se trouve alors supporté dans le corps de regard par la collerette d'appui 9, cette dernière venant recouvrir en partie ou en totalité la rive supérieure du corps de regard.As can be seen in FIG. 3, the protection device 6 is engaged by its shank 7 in the viewing body 3 and bears against the underside of the collar 9 on the upper edge of the viewing body. The was 7 of the protective device 6 is then supported in the body of gaze by the support flange 9, the latter coming to cover part or all of the upper edge of the body of view.

Ce dispositif assure donc une obturation étanche du volume interne du regard de chaussée, ainsi les matériaux de revêtement lors de l'épandage ne pourront pas pénétrer dans ce dernier. La forme en creux que constitue le panier permet la récupération des matériaux épandus au-dessus du regard de chaussée 1 sans que le volume de matériaux délivré ne puisse remplir totalement le panier. Ainsi la dépression que constitue la forme de panier sera toujours visible même après épandage des matériaux de revêtement, l'emplacement du regard de chaussée sera donc toujours apparent. Il est bien certain que le volume du panier est calculé de façon à être toujours supérieur à la valeur du volume de matériau déversé au-dessus du regard de chaussée. A titre d'exemple purement indicatif le volume du panier pour un regard de chaussée du type bouche à clé d'un diamètre de 84 mm sera supérieur à 60 cm3.This device thus ensures sealing of the internal volume of the manhole, so coating materials during spreading can not enter the latter. The recessed shape that constitutes the basket allows the recovery of materials spread above the manhole 1 without the volume of materials delivered can not completely fill the basket. Thus the depression that is the basket shape will always be visible even after spreading coating materials, the location of the gaze will always be apparent. It is certain that the volume of the basket is calculated so as to always be greater than the value of the volume of material poured above the manhole. By way of purely illustrative example, the volume of the basket for a key-lock type roadway with a diameter of 84 mm will be greater than 60 cm 3 .

Lors de l'épandage, la collerette 9 du dispositif 6 selon l'invention se trouve recouverte par le revêtement de la chaussée. Ceci n'est pas gênant en soi, le retrait du dispositif étant effectué dès le revêtement apposé et toujours avant durcissement de ce dernier.During spreading, the flange 9 of the device 6 according to the invention is covered by the pavement coating. This is not a problem in itself, the removal of the device being performed as soon as the coating affixed and always before curing of the latter.

En figure 3 on peut remarquer que le fût du dispositif de recouvrement, grâce à sa conicité, se trouve écarté de la face interne du corps de bouche à clé.In Figure 3 it can be seen that the barrel of the covering device, thanks to its conicity, is spaced from the inner face of the body of key-lock.

Le dispositif selon l'invention est préférentiellement du type à usage unique. En figure 4 est représenté un outil 10 pour la manipulation du dispositif 6 de recouvrement temporaire selon l'invention.The device according to the invention is preferably of the disposable type. In Figure 4 is shown a tool 10 for the handling of the temporary recovery device 6 according to the invention.

Cet outil comprend une poignée de manœuvre 11 auquel est fixé un guide tubulaire vertical 12, de section droite circulaire, comportant à l'opposé de la poignée de manœuvre un second guide tubulaire horizontal 13 dans lequel est montée en coulissement au moins une aiguille 14 de perforation et de préhension actionnée par un mécanisme de manœuvre à came 15 monté dans le guide tubulaire vertical 12 et pénétrant dans le guide tubulaire horizontal 13 pour y actionner l'aiguille 14 depuis une position rétractée dans le guide horizontal 13 vers une position déployée en dehors de ce guide selon laquelle l'aiguille 14 est assujettie à la préhension du dispositif 6 de recouvrement par perforation du fut 7 de ce dernier.This tool comprises a handle 11 to which is attached a vertical tubular guide 12, of circular cross section, having the opposite of the handle of operating a second horizontal tubular guide 13 in which is slidably mounted at least one perforation and gripping needle 14 actuated by a cam actuation mechanism 15 mounted in the vertical tubular guide 12 and penetrating the horizontal tubular guide 13 to actuate therein the needle 14 from a retracted position in the horizontal guide 13 to a deployed position outside this guide that the needle 14 is subject to gripping the device 6 recovery by perforation of the latter 7 thereof.

Le mécanisme de manœuvre 15 comporte un bouton de manœuvre 16 par appui sur lequel ledit mécanisme de manœuvre 15 est actionné depuis une position de repos selon laquelle l'aiguille 14 est rétractée dans le guide tubulaire 13 vers une position active selon laquelle l'aiguille 14 est déployée. L'actionnement du mécanisme de la position de repos vers la position active s'effectue à Fencontre de l'action de premier 18 et second 19 organes élastiques de rappel agissant respectivement sur ledit mécanisme de manœuvre 15 et sur ladite aiguille (14). Ce mécanisme de manœuvre 15 est constitué par une tige rigide 15a montée en coulissement dans le guide tubulaire vertical 12 et dans un perçage traversant lia formé dans la poignée de manœuvre 11, cette tige recevant en extrémité supérieure le bouton de manœuvre 16 et en extrémité inférieure et ce dans le guide tubulaire horizontal 13, une came d'actionnement 17 de l'aiguille 14. Le premier organe élastique de rappel 18 est installé dans un élargissement du perçage traversant lia que comporte la poignée 11, cet organe élastique de rappel 18, constitué par exemple par un ressort à spires non jointives, étant disposé autour de la tige rigide 15a et ce en compression entre le fond de l'élargissement 1 la et un épaulement de la tige 15a. Cet organe élastique a pour but de ramener la tige 15a en position de repos dès que cesse la sollicitation sur le bouton de manœuvre 16.The operating mechanism 15 comprises an operating button 16 by pressing on which said operating mechanism 15 is actuated from a rest position in which the needle 14 is retracted into the tubular guide 13 to an active position according to which the needle 14 is deployed. The actuation of the mechanism from the rest position to the active position is effected against the action of first 18 and second 19 resilient return members respectively acting on said operating mechanism 15 and said needle (14). This operating mechanism 15 is constituted by a rigid rod 15a slidably mounted in the vertical tubular guide 12 and in a through bore 11a formed in the operating handle 11, this rod receiving at the upper end the operating knob 16 and at the lower end and in the horizontal tubular guide 13, an actuating cam 17 of the needle 14. The first elastic return member 18 is installed in an enlargement of the through bore 11a which the handle 11 comprises, this elastic return member 18, constituted for example by a spring with non-contiguous turns, being disposed around the rigid rod 15a and in compression between the bottom of the widening 1 la and a shoulder of the rod 15a. This elastic member is intended to bring the rod 15a to the rest position as soon as the pressure on the operating knob 16 ceases.

Le second organe élastique de rappel 19, du type ressort à spires non jointives, est installé dans le guide tubulaire horizontal 13 autour de l'aiguille 14 entre un épaulement interne du guide 13 et un épaulement de l'aiguille 14 afin de solliciter cette dernière vers sa position rétractée. La came 17 présente une surface de rampe sur laquelle prend appui l'extrémité correspondante de l'anguille 14. Par mouvement de la came vers le bas, la surface de rampe repousse progressivement l'aiguille 14 vers sa position déployée. Préférentiellement, l'outil 10 comporte deux aiguilles 14 montées en opposition l'une par rapport à l'autre dans un même guide tubulaire et actionnées de manière simultanée par un seul et même mécanisme de manœuvre 15. Selon cette forme de réalisation, la came 17 présente deux surfaces de rampe opposées l'une par rapport à l'autre, conférant à la came un profil triangulaire à pointe dirigée vers le bas. .The second elastic return member 19, spring-type non-contiguous turns, is installed in the horizontal tubular guide 13 around the needle 14 between an inner shoulder of the guide 13 and a shoulder of the needle 14 to solicit the latter towards its retracted position. The cam 17 has a ramp surface on which bears the corresponding end of the eel 14. By movement of the cam downwards, the ramp surface progressively pushes the needle 14 towards its extended position. Preferably, the tool 10 comprises two needles 14 mounted in opposition to one another in the same tubular guide and actuated simultaneously by a single operating mechanism 15. According to this embodiment, the cam 17 has two opposite ramp surfaces with respect to each other, giving the cam a triangular profile point directed downwards. .

Selon une forme préférée de réalisation, le guide tubulaire 13 est formé dans un disque horizontal 20. Ce disque permet de centrer l'outil dans le fut du dispositif de recouvrement temporaire.According to a preferred embodiment, the tubular guide 13 is formed in a horizontal disc 20. This disc allows to center the tool in the temporary covering of the device.

Il va de soi que la présente invention peut recevoir tous aménagements et variantes du domaine des équivalents techniques, sous pour autant sortir du présent titre.It goes without saying that the present invention may receive any arrangements and variations in the field of technical equivalents, under this title.
