Abstract

The invention concerns an inflatable anti-flood barrier consisting of an inflatable elongated envelope (4) housed in a drain (1) buried in the ground (2) and normally closed with a hinged metal plate (3) designed to be lifted and maintained in a substantially vertical position when the envelope (4) is inflated to act as support for the latter on the side opposite to that subjected to the pressure of the water. The invention relates generally to equipment for controlling floods, whether caused by very high swelling of rivers or abnormally heavy rains.

Description

BARRAGE GONFLABLE ANTI-CRUES ANTI-FLOOD INFLATABLE DAM
La présente invention a pour objet un barrage gonflable anti-crues.The present invention relates to an inflatable flood barrier.
Elle se rapporte d'une manière générale aux équipements destinés à lutter contre les inondations, que celles-ci soient dues à la forte montée du niveau de cours d'eau ou à des pluies anormalement abondantes.It generally relates to equipment intended to fight against floods, whether these are due to the sharp rise in the level of the watercourse or to abnormally heavy rains.
Les dispositifs réalisés à ce jour et destinés à protéger certaines zones contre les inondations sont constitués soit de palissades amovibles généralement en bois destinées à être montées en cas de nécessité sur des supports installés à demeure, soit de plates-formes métalliques relevables actionnées par des vérins hydrauliques ou pneumatiques.The devices produced to date and intended to protect certain areas against flooding are made up either of removable wooden fences generally made of wood intended to be mounted if necessary on permanently installed supports, or of lifting metal platforms actuated by jacks hydraulic or pneumatic.
Les systèmes utilisant des palissades amovibles demandent une durée et une main d'oeuvre importante pour être mis en place, ce qui entraîne la plus souvent l'obligation de les installer à l'avance, à titre préventif, parfois inutilement. Les plates-formes métalliques relevables, en raison de leur coût élevé doivent être réservées à un nombre très restreint de cas tels que l'entrée d'un centre commercial, par exemple.Systems using removable fences require a long time and a significant labor to be set up, which most often entails the obligation to install them in advance, as a preventive measure, sometimes unnecessarily. Lifting metal platforms, because of their high cost, must be reserved for a very limited number of cases such as the entrance to a shopping center, for example.
Le dispositif selon la présente invention a pour objectif de remédier à cet état de choses. Il permet en effet de réaliser avec un investissement raisonnable des barrages contre les inondations pouvant atteindre des longueurs importantes et se mettant en place, éventuellement automatiquement, très rapidement et sans l'intervention de main d'oeuvre.The device according to the present invention aims to remedy this state of affairs. It makes it possible, with a reasonable investment, to build dams against floods which can reach significant lengths and which can be set up, possibly automatically, very quickly and without the intervention of labor.
II est constitué d'une enveloppe gonflable allongée logée dans un caniveau enterré 'dans le sol et normalement fermé par une plaque métallique articulée déterminée pour se relever et se maintenir dans une position sensiblement verticale lors du gonflage de l'enveloppe de manière à servir d'appui à cette dernière du côté opposé à celui où s'exerce la pression de l'eau. Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention : la figure 1 est une coupe perpendiculaire à l'axe de l'enveloppe gonflable montrant le dispositif en position de repos, la figure 2 montre dans les mêmes conditions le dispositif en position active avec l'enveloppe gonflée et la figure 3 est un agrandissement du détail D1 de la figure 2.It consists of an elongated inflatable envelope housed in a gutter buried 'in the ground and normally closed by an articulated metal plate determined to rise and maintain itself in a substantially vertical position during inflation of the envelope so as to serve as support to the latter on the side opposite to that where the water pressure is exerted. In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the object of the invention: FIG. 1 is a section perpendicular to the axis of the inflatable envelope showing the device in position FIG. 2 shows the device in the active position with the envelope inflated under the same conditions, and FIG. 3 is an enlargement of detail D1 in FIG. 2.
Le dispositif, figures 1 à 3, est constitué d'un caniveau 1 enterré dans le sol 2, fermé par une plaque métallique 3 articulée et contenant une enveloppe 4 gonflable allongée apte, lorsqu'elle est mise sous pression, à se développer au dessus du sol en relevant la plaque métallique pour former un barrage contre le passage des eaux.The device, FIGS. 1 to 3, consists of a channel 1 buried in the ground 2, closed by a metal plate 3 articulated and containing an elongated inflatable casing 4 capable, when it is pressurized, to develop above from the ground by raising the metal plate to form a dam against the passage of water.
L'enveloppe 4 gonflable est formée d'un fourreau réalisé en toile caoutchoutée semblable à celle utilisée pour la réalisation des canots pneumatiques de type "Zodiac". Elie sera avantageusement préformée pour se replier en zigzag dès que la pression de gonflage est supprimée, de façon à réintégrer le caniveau 1 sans intervention (figure 1), la plaque 3 de fermeture se rabattant sur le caniveau grâce à des câbles de traction 5.The inflatable envelope 4 is formed of a sheath made of rubberized canvas similar to that used for the production of inflatable boats of the "Zodiac" type. Elie will advantageously be preformed to fold in a zigzag as soon as the inflation pressure is removed, so as to reintegrate the channel 1 without intervention (FIG. 1), the closure plate 3 folding back on the channel using traction cables 5.
Le gonflage s'effectue grâce à des raccords souples 6 branchés sur l'enveloppe 4 et reliés à une conduite 7 cheminant à l'intérieur du caniveau. Cette conduite est alimentée par une source d'air comprimé pouvant être déclenchée en cas de risque d'inondation. De préférence la source d'air comprimé sera constituée de bouteilles sous pression ou d'un compresseur à moteur thermique de façon à ce que la mise en service de l'installation ne dépende pas du réseau de distribution électrique.The inflation takes place by means of flexible connectors 6 connected to the casing 4 and connected to a pipe 7 running inside the gutter. This line is supplied by a source of compressed air which can be triggered in the event of risk of flooding. Preferably, the source of compressed air will consist of pressure cylinders or a compressor with a thermal engine so that the commissioning of the installation does not depend on the electrical distribution network.
L'enveloppe 4 comporte à sa partie inférieure une lèvre permettant de la fixer solidement au moyen d'un fer plat 8 boulonné sur un rail 9 scellé dans le fond du caniveau* 1.The casing 4 has at its lower part a lip making it possible to fix it securely by means of a flat iron 8 bolted to a rail 9 sealed in the bottom of the gutter * 1.
La face de l'enveloppe gonflable située du côté de l'arrivée des eaux sera avantageusement revêtue d'une protection 10 anti-déchirure pouvant être • constituée d'un film résistant renforcé de fibres de verres. Lorsque le barrage est d'une longueur importante, l'enveloppe gonflable pourra être formée de plusieurs tronçons solidarisés par un câble maintenu au moyen de fixations 11 arrimées sur le faîte de l'enveloppe 4.The face of the inflatable envelope situated on the water inlet side will advantageously be coated with a tear-resistant protection which may be made up of a resistant film reinforced with glass fibers. When the dam is of considerable length, the inflatable envelope may be formed of several sections secured by a cable maintained by means of fasteners 11 stowed on the ridge of the envelope 4.
La plaque métallique 3 est articulée sur le côté du caniveau 1 en aval du passage des eaux, de façon à se relever lorsque l'enveloppe 4 est gonflée et sort du caniveau. Cette plaque est agencée pour servir d'appui à l'enveloppe gonflable 4 contre la poussée des eaux. A cet effet, une série de jambes de forces 12 sont disposées le long de la plaque relevable 3 et agencées de façon à venir reposer sur le sol 2 lorsque la plaque 3 est en position de service.The metal plate 3 is articulated on the side of the gutter 1 downstream of the passage of the waters, so as to rise when the envelope 4 is inflated and leaves the gutter. This plate is arranged to serve as a support for the inflatable envelope 4 against the push of water. To this end, a series of struts 12 are arranged along the liftable plate 3 and arranged so as to come to rest on the ground 2 when the plate 3 is in the service position.
En variante, le gonflage de l'enveloppe 4 peut être assuré par une source d'eau sous pression pouvant être déclenchée en cas de risque d'inondation, cette source pouvant consister en un réseau de distribution ou un système de pompage motorisé.As a variant, the envelope 4 can be inflated by a source of pressurized water which can be triggered in the event of a risk of flooding, this source being able to consist of a distribution network or a motorized pumping system.
Le fonctionnement du barrage peut aisément être automatisé au moyen de détecteurs d'humidité, ou commandé à distance. Dans ce cas, l'installation sera complétée par des signaux lumineux 13 et des avertisseurs sonores 14 disposés aux lieux de passage et déclenchés avant la mise sous pression de l'enveloppe 4 gonflable,The operation of the dam can easily be automated by means of humidity detectors, or controlled remotely. In this case, the installation will be completed by light signals 13 and audible warning devices 14 placed at the passageways and triggered before the inflatable envelope 4 is pressurized,
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
