Abstract

Procedimiento para el acoplamiento de un dispositivo de drenaje según el cual un tubo de drenaje flexible de materia sintética provisto de aberturas es desplazado a velocidad constante, una cinta permeable al agua es llevada a la misma velocidad constante y abatida de manera continua alrededor del tubo de drenaje, con objeto de formar una funda permeable al agua que rodea el tubo de drenaje a unas cierta distancia, estando cerrada una faja de filtración de material filtrante entre el tubo de drenaje y dicha funda, caracterizado porque entre el tubo de drenaje y la funda, se forma un espacio anular cuya altura es constante según la circunferencia del tubo y se llena este espacio de material filtrante por vía neumática.
