Abstract

Arrangement for covering large areas of dammed water, characterized in that for this purpose the means or covering element used will be constituted by a support of a fabric or a "non-woven" of any natural, artificial or synthetic fiber that has to be to undergo an appropriate buoyancy or flotation force to stay on the surface of the fluid, which is achieved by virtue of a floatation means or elements of spongy foam or flexible closed-pored foam, whose ascending thrust is assured provided that the density of the assembly is less than one unit, with whose spongy or foamed materials are obtained densities of 0.2 kg per cubic decimeter, which provides a thrust of 0.8 kg also per cubic decimeter, depending on the dimensioning of the means or elements of flotation and the distance between them, their own weight and the support or cover element; the drainage of the assembly is achieved by the own porosity of the fabric or material used or by means of openings, slits or holes that the covering means or element may carry between the interstices or free spaces located between the flotation elements, which provides a cover sufficiently permeable to water, at least, in an amount of 50 liters per square meter per minute and the necessary self-flotation or self-carrying, since said cover will be placed on the surface of the fluid without necessity of any element or means of subjection, mooring or anchoring.
