Abstract
Description
<Desc/Clms Page number 1> <Desc / Clms Page number 1>
La présente invention est destinée à l'entretien des souilles de quais, en particulier dans les ports fluviaux soumis à l'action du courant. The present invention is intended for the maintenance of the soils of quays, in particular in the river ports subjected to the action of the current.
Les engins actuellement utilisés pour effectuer ces opérations sont : * des dragues à benne preneuse, qui peuvent aller claper au large ou dans des fosses, ce qui réduit le rendement par perte de temps en vidage, ou décharger dans des barges, ce qui nécessite la mobilisation d'un pousseur pour leur évacuation et leur remplacement. The machines currently used to carry out these operations are: * clamshell dredges, which can go off in the open or in pits, which reduces the yield by loss of time in emptying, or unload in barges, which requires the mobilization of a pusher for their evacuation and replacement.
* des dragues aspiratrices, qui ont un excellent rendement, mais sont inadaptées pour draguer au pied des quais. * suction dredgers, which have excellent performance, but are unsuitable for dredging at the foot of the quays.
Ces deux types d'engin doivent être conduits par un équipage et ne sont donc présents que dans les grands ports disposant de moyens financiers importants. Les ports plus petits doivent louer leurs services suivant la disponibilité des engins et régler les frais d'amener, ce qui représente un coût bien supérieur à l'utilisation de la présente invention. These two types of equipment must be driven by a crew and are therefore only present in large ports with significant financial resources. Smaller ports must hire their services according to the availability of equipment and pay the costs of bringing them, which represents a cost much higher than the use of the present invention.
Celle ci est composée d'un ponton flottant (l), de dimensions suffisantes pour supporter un groupe électrogène (9), un compresseur d'air (3), une pompe d'aspiration eau de mer (4), un compresseur haute pression (5), une cabine de commande (2) et des treuils de positionnement (7). This consists of a floating pontoon (l), of sufficient dimensions to support a generator (9), an air compressor (3), a seawater suction pump (4), a high pressure compressor (5), a control cabin (2) and positioning winches (7).
La partie centrale du ponton est évidée de façon à permettre le passage d'une grille formée de tubes. The central part of the pontoon is hollowed out so as to allow the passage of a grid formed of tubes.
Les ancres du ponton sont préalablement positionnées aux extrémités de la souille concernée. The pontoon anchors are positioned beforehand at the ends of the affected soil.
Des sondeurs détectent la hauteur du fond, envoient l'information à une centrale qui commande l'action des treuils (6) amenant la grille à la profondeur voulue, au plus près du fond. Sounders detect the height of the bottom, send the information to a central unit which controls the action of the winches (6) bringing the grid to the desired depth, as close as possible to the bottom.
Lorsque le courant de jusant s'établit, un courantomètre (11) envoie un signal à la centrale qui démarre la pompe aspiratrice eau de mer et le compresseur haute pression. When the ebb current is established, a current meter (11) sends a signal to the central unit which starts the seawater suction pump and the high pressure compressor.
Celui ci alimente une partie des tubes de la grille percés suivant un angle dirigé vers la partie inférieure, d'où les jets désagrègent les matières constituant le fond. Le compresseur d'air alimente l'autre partie des tubes de la grille, percés en leur face inférieure, laissant échapper de l'air remettant les matériaux en suspension dans le milieu aqueux. This feeds part of the grid tubes pierced at an angle directed towards the lower part, from where the jets disintegrate the materials constituting the bottom. The air compressor supplies the other part of the grid tubes, pierced on their underside, letting air escape, putting the materials in suspension in the aqueous medium.
Le courant de jusant transporte les matériaux vers l'aval. The flow of ebb transports the materials downstream.
Un programme de route associé à un GPS (Global Positionning System) asservit la centrale de commande pour actionner les treuils de guidage du ponton, et lui permettre de progresser en papillonnant. A route program associated with a GPS (Global Positioning System) controls the control unit to activate the pontoon's guide winches, and allow it to progress by fluttering.
Lorsque le courant de jusant est insuffisant, le courantomètre envoie un signal à la centrale de commande qui procède à l'arrêt du dispositif La centrale de commande peut se programmer en fonction des renverses de courant, suivant le calcul des heures de marée, et peut tenir compte de périodes de repos suivant les circonstances (reproduction d'espèces, alevinage,...) La grille peut être amenée en position haute pour le nettoyage et un entretien facile. Elle peut être équipée de microfiltres (chimiques, magnétiques, physiques,...) pour capter les matières toxiques pour l'environnement.When the ebb current is insufficient, the current meter sends a signal to the central control unit which proceeds to stop the device The central control unit can be programmed according to current reversals, according to the calculation of the tide hours, and can take into account rest periods depending on the circumstances (reproduction of species, nursery, ...) The grid can be brought to the high position for cleaning and easy maintenance. It can be equipped with microfilters (chemical, magnetic, physical, ...) to capture materials toxic to the environment.
