Abstract
Description
La présente invention concerne l'entretien et la réparation de tabliers de pont et est relative à un dispositif, qui permet la mise en oeuvre des techniques d'entretien et de réparation aussi variées que, par exemple, sablage ou hydrosablage in situ et peinture, réparation des bétons endommagés ou fissures, adjonction de plats de renfort soudés, boulonnés ou rivés ou tout autre travail d'entretien ou de réparation sans interrompre le trafic.The present invention relates to the maintenance and repair of bridge decks and relates to a device, which allows the implementation of maintenance and repair techniques as varied as, for example, sandblasting or sandblasting in situ and painting, repair of damaged concrete or cracks, addition of welded, bolted or riveted reinforcing plates or any other maintenance or repair work without interrupting traffic.
L'entretien ou la réparation des tabliers et autres parties des ponts-route ou des ponts-rail nécessite la disposition d'un important matériel à proximité de l'équipe effectuant le travail.The maintenance or repair of the decks and other parts of the road or rail bridges requires the provision of significant equipment near the team performing the work.
Il est ainsi, le plus souvent, nécessaire d'interrompre le trafic sur la partie du pont en cours d'entretien ou de réparation ou, à tout le moins, d'interrompre le trafic sur une des bandes de circulation au moins. Il en résulte de nombreux inconvénients, parmi lesquels on peut relever à titre exemplatif :
- réduction de fluidité du trafic ;
- danger accru aux heures de pointes, surtout en cas de brouillard ;
- danger permanent pour les ouvriers amenés à circuler sur la chaussée ou en bordure de celle-ci ;
- coût élevé de la signalisation, tant en ce qui concerne son installation que son entretien.It is therefore most often necessary to interrupt the traffic on the part of the bridge undergoing maintenance or repair or, at the very least, to interrupt the traffic on at least one of the traffic lanes. This results in many drawbacks, among which we can note by way of example:
- reduction in traffic flow;
- increased danger during peak hours, especially in fog;
- permanent danger for the workers brought to circulate on the pavement or on the edge thereof;
- high cost of signage, both in terms of its installation and maintenance.
Le but de l'invention est de permettre la mise en oeuvre de toutes ces techniques en toute sécurité pour le personnel d'exécution, de surveillance et de maintenance, en toute sécurité pour l'environnement et en toute sécurité pour le trafic, particulièrement en temps de brouillard.The object of the invention is to allow the implementation of all these techniques in complete safety for the execution, monitoring and maintenance personnel, in complete safety for the environment and in complete safety for traffic, particularly in foggy weather.
On connaît par le brevet US-A-3 550 723 un échafaudage mobile de pont comportant un châssis allongé s'étendant en travers du pont et portant à chacune de ses extrémités des montants dirigés vers le bas pour supporter une plateforme allongée se déployant sous le pont.US patent A-3,550,723 discloses a mobile bridge scaffolding comprising an elongated frame extending across the bridge and carrying at each of its ends uprights directed downward to support an elongated platform deploying under the bridge.
Une telle réalisation a été conçue dans le but de permettre l'accès aux ouvriers pendant la construction du pont. Elle ne permet pas d'être utilisée pour un entretien ou une réparation à un pont sans interrompre le trafic, ce qui est le but de l'objet de la demande.Such an embodiment was designed in order to allow access to workers during the construction of the bridge. It does not allow it to be used for maintenance or repair at a bridge without interrupting traffic, which is the purpose of the subject of the request.
On connaît aussi par le brevet US-A-3 587 125 une poutre en plusieurs sections, qui sert d'élément de pont montée à ses extrémités sur des éléments de tour éventuellement mobiles, plusieurs de ces poutres pouvant être assemblées pour recevoir une plateforme. Ce dispositif ne permet pas de répondre au problème soulevé par la présente demande dans la mesure où la principale sollicitation, à laquelle on doit faire face, réside dans les sollicitations dynamiques du vent ainsi que celles consécutives au déplacement d'air des poids lourds, tels que camions, autocars, etc.Also known from US-A-3,587,125 is a beam in several sections, which serves as a bridge element mounted at its ends on possibly mobile tower elements, several of these beams being able to be assembled to receive a platform. This device does not make it possible to respond to the problem raised by the present request insofar as the main request, which one has to face, resides in the dynamic wind loads as well as those resulting from the movement of air by heavy goods vehicles, such as trucks, coaches, etc.
La conception du dispositif faisant l'objet de ce brevet US-A-3 587 125 - passerelle reposant sur deux tours par l'intermédiaire de deux rotules - limite structurellement la résistance dudit dispositif aux sollicitations latérales et tout particulièrement aux sollicitations dynamiques.The design of the device which is the subject of this patent US Pat. No. 3,587,125 - gangway resting on two towers by means of two ball joints - structurally limits the resistance of said device to lateral stresses and very particularly to dynamic stresses.
Le seul moyen d'y pallier consisterait à élargir la base des tours ; ceci est formellement exclu dans le dispositif suivant la demande, puisque l'objectif de départ est justement de ne pas empiéter sur la voie.The only way to overcome this would be to widen the base of the towers; this is formally excluded in the device according to demand, since the starting objective is precisely not to encroach on the track.
Le dispositif faisant l'objet de la demande a été spécifiquement conçu pour résister à ce type de sollicitations en prenant comme parti structurel une série de portiques hyperstatiques rigides contreventés latéralement et horizontalement. Ledit dispositif présente ainsi une grande résistance aux sollicitations dynamiques latérales résultant, par exemple, de la prise au vent des silos et autres matériels indispensables à l'exécution des travaux.The device which is the subject of the request has been specifically designed to resist this type of stress by taking as a structural part a series of rigid hyperstatic gantries braced laterally and horizontally. Said device thus has a great resistance to lateral dynamic stresses resulting, for example, from the winding of silos and other materials essential to the execution of the work.
Un dispositif suivant l'invention est caractérisé en ce qu'il consiste en une ossature constituée d'une série de portiques hyperstatiques rigides, contreventés latéralement et horizontalement destinée à enjamber la voie concernée par l'entretien et/ou la réparation du tablier de pont et montée sur roues, de façon à permettre son déplacement le long de cette voie, et en ce que sur sa charpente horizontale est amenagé un plateau de service constitué d'éléments de plancher autoportants, servant d'atelier et destiné à l'entreposage du matériel d'entretien et de réparation.A device according to the invention is characterized in that it consists of a framework constituted by a series of rigid hyperstatic gantries, braced laterally and horizontally intended to span the track concerned by the maintenance and / or repair of the bridge deck and mounted on wheels, so as to allow its movement along this track, and in that on its horizontal frame is arranged a service tray consisting of floor elements freestanding, used as a workshop and intended for the storage of maintenance and repair equipment.
Suivant l'invention l'ossature métallique est adaptable en largeur en fonction du gabarit de la voie à franchir, sa longueur étant modulable en fonction de sa largeur, de façon à toujours présenter une surface utile de plateau suffisante.According to the invention the metal frame is adaptable in width as a function of the size of the track to be crossed, its length being adjustable as a function of its width, so as to always have a sufficient useful surface of the platform.
Pour mieux faire comprendre l'invention celle-ci est décrite maintenant sur la base des dessins annexés, à titre d'exemple uniquement, montrant en :
- Figure 1 une vue en élévation de profil d'un portique tunnel suivant l'invention ;
- Figure 2 une coupe transversale dans le portique tunnel de la figure 1, et
- Figure 3 une vue en plan par dessus du plateau surmontant le portique tunnel.
- Figure 1 a side elevational view of a tunnel gantry according to the invention;
- Figure 2 a cross section in the tunnel gantry of Figure 1, and
- Figure 3 a plan view from above of the tray above the tunnel gantry.
Comme on le voit aux dessins un dispositif conforme à l'invention consiste en une ossature métallique 1 du type portique tunnel qui est montée sur des roues 2 de façon à permettre son déplacement le long de la voie concernée au fur et à mesure de l'avancement des travaux.As can be seen in the drawings, a device according to the invention consists of a metal frame 1 of the tunnel gantry type which is mounted on
Sa charpente horizontale 3 supporte un plateau 4.Its horizontal frame 3 supports a
Ladite ossature 1 est destinée à enjamber une chaussée 5, en particulier une chaussée de pont ou voie de chemin de fer, et sa largeur est fonction du gabarit de cette chaussée, de telle manière qu'elle n'empiète pas sur la largeur de la voie à laisser entièrement libre.Said frame 1 is intended to span a carriageway 5, in particular a bridge carriageway or railway track, and its width depends on the size of this carriageway, so that it does not encroach not over the width of the track to be left entirely free
La longueur de l'ossature ou portique tunnel est modulable en fonction de sa largeur, de façon à toujours présenter une surface utile de plateau suffisante.The length of the tunnel frame or gantry is adjustable according to its width, so as to always have a sufficient useful surface of the platform.
La hauteur de l'ossature est d'environ 5,5 m de manière à permettre le passage de tous les véhicules courants, tout en minimisant les effets dynamiques dûs au déplacement d'air.The height of the frame is approximately 5.5 m to allow the passage of all common vehicles, while minimizing the dynamic effects due to air movement.
Le plateau 4 est constitué d'éléments de plancher autoportants destinés à l'entreposage du matériel nécessaire à l'entretien ou à la réparation du pont et servant en même temps d'éléments de contreventement horizontal. Sur ce plateau sont avantageusement aménagés un atelier 6 et des locaux 7 pour la maintenance, la surveillance et le personnel. Une trémie d'accès 8 avec treuil électromécanique fixé au plateau sert à l'approvisionnement du matériel et des matériaux, et des échelles 9 servent à l'accès du personnel sur le plateau de service.The
Dans le cas particulier du sablage et de la métallisation d'un tablier de pont métallique le matériel comprend essentiellement deux groupes électrogènes, dont un de secours, deux compresseurs, dont un de secours, un silo pour le stockage du corindon ou des scories et un silo pour la récupération des résidus de sablage.In the particular case of sandblasting and metallization of a metal bridge deck, the equipment essentially comprises two generators, one of which is a backup, two compressors, one of which is a backup, a silo for the storage of corundum or slag and a silo for the recovery of sandblasting residues.
En dessous du plateau 4 est prévue une installation d'éclairage de la chaussée, telle qu'une série de lampes au sodium assurant la sécurité du trafic nocturne. Le niveau d'éclairement des voies couvertes sera aussi élevé que souhaité par le maître d'ouvrage, surtout par temps de brouillard.Below the
L'évacuation des résidus se fait par un système de goulottes télescopiques canalisant les matières pulvérulentes directement de la trémie du silo de récupération dans des camions, qui viendront se disposer en dessous durant les heures creuses.The residue is evacuated by a system of telescopic troughs channeling the pulverulent materials directly from the hopper of the recovery silo in trucks, which will be disposed of during off-peak hours.
Le portique tunnel conforme à l'invention est conçu pour être facilement démonté, déplacé et adapté à n'importe quel gabarit de voierie.The tunnel gantry according to the invention is designed to be easily dismantled, moved and adapted to any size of roadway.
