Abstract

The installation is in the form of a pipe or tunnel (B) formed through the full length of the weir etc. The internal surface of the tunnel presents a series of annular or similar sections, promoting turbulence in a flow of water through the tunnel and reducing its flow speed and force. The tunnel is defined by an elongate cylindrical tube wound as a spiral or similar, with a shallow overall inclination of about 10 per cent, and restricts the water flow rate to about 1 metre/second. The length and diameter of the loops of the tube vary according to the length of the weir etc. to be bypassed. USE/ADVANTAGE - By-pass conduit for weir, waterfall etc which allows fish etc. to pass safely through waterway obstructions with minimum effort.

Description

ECHELLE A POISSONS dite en TUNNEL
La présente invention concerne un procédé et dispositif permettant aux poissons de remonter les cours d'eaux sur lesquels se trouvent des obstacles naturels ou artificiels tels que barrages ou autres retenues, pour se reproduire après leur période migratoire.FISH LADDER called TUNNEL
The present invention relates to a method and device allowing fish to go up streams on which there are natural or artificial obstacles such as dams or other reservoirs, to reproduce after their migratory period.

Le principe de ce dispositif en "tunnel est de démultiplier la hauteur d'eau à franchir en multipliant la longueur du tuyau, environ par 10, par rapport à la hauteur de la chute d'eau, afin que les paissons la posibilité de remonter avec contre-courant à débit réduit.The principle of this "tunnel" device is to multiply the height of the water to be crossed by multiplying the length of the pipe, approximately by 10, compared to the height of the waterfall, so that the grazers are able to rise with reduced flow counter current.

II existe actuellement plusiwrs procédés dont les principaux sont: - la passe en escalier, à bassins successifs : la hauteur d'eau à franchir est divisée en plusieurs petits chutes formant des bassins qui communiquent entre wx par des déwrsoirs.  There are currently several methods, the main ones of which are: - the staircase pass, with successive basins: the height of water to be crossed is divided into several small falls forming basins which communicate between wx by dewrsoirs.

- l'écluse à poissons (écluse "Borland") : les poissons migrateurs sont piégés dans un sas et éclusés, suivant le principe de l'écluse à bateau. - the fish lock ("Borland" lock): the migrating fish are trapped in an airlock and locked, following the principle of the boat lock.

- l'échelle à ralentisseurs (ou "Denil") : des déflecteurs de formes plus ou moins complexes sont disposés sur le fond et/ou sur les parols d'un canal à forts pente. afin de réduire la vitesse d'écoulement de l'eau.- the scale with retarders (or "Denil"): deflectors of more or less complex shapes are placed on the bottom and / or on the floors of a steep slope. to reduce the speed of water flow.

Chacun de ces systèmes de passes est plus ou moins efficace, selon l'équipement des sites et selon des critères relatifs au comportement des poissons ainsi qu'à l'aspect et à l'aménagement naturel ou artificiel de la chute d'eau. Each of these pass systems is more or less effective, depending on the equipment of the sites and according to criteria relating to the behavior of the fish as well as the appearance and the natural or artificial arrangement of the waterfall.

L'invention décrite cl-après présente les avantages suivents: 1/ Lss poissons montent w descendent dans leur élément naturel, le long d'un corridor en pente doucs, aménagé pour leur permettre d'atteindrs leur lieu de reproduction dans les meilleurs conditions.The invention described below has the following advantages: 1 / Lss fish go up w go down in their natural element, along a gently sloping corridor, arranged to allow them to reach their place of reproduction in the best conditions.

2/ Le dispositif installé, dit en "tunnel" est statique, il ne subit pas, ou trb peu, les effets du temps et n'exige pas d'entretien En effet, il n'y a aucune pièce en mouvement, car il n'y a pas d'apport d'énergie. 2 / The installed device, called "tunnel" is static, it does not undergo, or very little, the effects of time and does not require maintenance. Indeed, there are no moving parts, because it there is no energy input.

3/ 11 est silencieux et peu encombrant, 4/ 11 est économique, de par la simplicité de sa conception et des matériaux utilisés.3/11 is silent and compact, 4/11 is economical, due to the simplicity of its design and the materials used.

En effet, il est constitué principalement de - I tuyau(B) annelé rigide ou souple, en ciment, métal, ou plastique, e diamètre variable, c'est-à-dire de 140 à 400 mm ou plus, et de longueur variable, suivant la hauteur de la chuts d'eau considérée et suivant le gabarit du poisson.Indeed, it mainly consists of - I rigid or flexible corrugated pipe (B), made of cement, metal, or plastic, e variable diameter, that is to say from 140 to 400 mm or more, and of variable length , depending on the height of the water drop in question and the size of the fish.

Ce tuyau annelé, est disposé en forme de "ressort" ou en spirales superposées, disposées le long de la chute d'eau1 et il peut être équipé de "reposoirs" créés a' intervalles réguliers, par une augmentation du diamètre du "tunnel". This corrugated pipe is arranged in the form of a "spring" or in superimposed spirals, arranged along the waterfall1 and it can be equipped with "rests" created at regular intervals, by increasing the diameter of the "tunnel" .

5/ La fabrication de ce dispositif est simple et peu coûteuse 6/ La mise en place ne demande pas d'installation complexe, 5 / The manufacture of this device is simple and inexpensive 6 / The installation does not require complex installation,
