Abstract

EL PROCEDIMIENTO TIENE DOS FASES. EN LA PRIMERA SE REALIZA POR COLADA DE CEMENTO O EQUIVALENTE AL MENOS UN ELEMENTO PORTADOR, AUTOPORTANTE, QUE PRESENTA RESERVAS (C) EN LAS CUALES SE ALOJAN MEDIOS, COMO BOQUILLAS, PARA INTRODUCIR LOS FLUIDOS DE LAVADO DEL FILTRO. EN LA SEGUNDA FASE, EL ELEMENTO PORTADOR SE SITUA EN SU LUGAR SOBRE LOS SOPORTES (F) DEL FILTRO, SE ECHA UNA SOLA VEZ CEMENTO ENCIMA DE ESTE ELEMENTO EN CANTIDA SUFICIENTE PARA ALCANZAR EL ESPESOR TOTAL DESEADO DE PISO Y REALIZAR ASI UNA BALDOSA (E) QUE RECOGERA EL MATERIAL GRANULAR A FILTRAR.
