Abstract

SE DISPONE DE UN CONJUNTO PARA BLOQUEAR PROVISIONALMENTE EL ANIMA DE UNA TUBERIA A CUYO TRAVES FLUYE UN FLUIDO, COMPRENDIENDO EL CONJUNTO UN CIERRE ESTANCO DE BOLSA FLEXIBLE Y EXPANDIBLE, QUE SE INTRODUCE A TRAVES DE UN ORIFICIO QUE HAY EN LA PARED DE LA TUBERIA, Y MEDIOS PARA INYECTAR DENTRO DEL CIERRE HERMETICO DE BOLSA UNA CANTIDAD DE UN MATERIAL ADAPTADO PARA EXPANDIRSE IN SITU EN EL CIERRE ESTANCO DE LA BOLSA E INFLAR EL MISMO CONTRA EL INTERIOR DE LA TUBERIA. LA TUBERIA PUEDE SER UNA CANALIZACION DE GAS Y EL MATERIAL UN MATERIAL ALVEOLAR DE RESINA SINTETICA EXPANSIBLE. EL CIERRE ESTANCO DE LA BOLSA SE ELIMINA MEDIANTE LA INYECCION EN SU INTERIOR DE UNA SUSTANCIA CAPAZ DE DISOLVER EL MATERIAL ALVEOLAR, CON LO QUE EL CIERRE ESTANCO DE LA BOLSA PUEDE DESINFLARSE, AL MENOS PARCIALMENTE.
