DEVICE FOR THE CREATION OF LOW SUBPRESSION ZONES IN THE TRANSFER OF PARAMENTS AND SOLERAS OF CHANNELS, DEPOSITS AND OTHER LIQUID CONTAINERS

摘要

Device for the creation of low underpressure zones in the trasdos of walls and screeds of channels, reservoirs and other containers of liquids. # In channels whose solera is below the level of groundwater, a buoyancy thrust occurs that compromises its stability. In order to avoid this problem, it is known to implant a tube that connects the lower ground to the channel with the interior of the latter, equipped with a unidirectional valve that prevents the liquid circulating through the channel from returning to the ground through said channel. tube. The device of the invention eliminates any type of valve and consists of a tube (1) that is fixed at its lower end to the hearth (3) of the channel (4), to which it crosses, counting such lower extremity with a flexible sleeve (7) which allows the tube to be folded down (1), with the consequent change in height of the water table (8) for access to the inside of the channel (4). A buoy or float (10) keeps the mouth of water outlet (8) in the vicinity of the level (9) of liquid (9) inside the channel (4), regardless of the height of said level.
