Abstract

M todo para revestir nuevamente conducciones preexistentes, aparato deformador y m todo correspondientes e inserto de tubo utilizado. M todo y aparato para revestir de nuevo, reparar o reconstruir sistemas de conducciones de infraestructuras preexistentes que son nuevas, estructuralmente deficientes o que experimentan una cantidad excesiva de exfiltraci n o infiltraci n, o convertir conducciones nuevas o da adas en conducciones de continente doble. Una pluralidad de tubos de revestimiento de trabajo de polietileno de alta densidad, que tienen una secci n trnasversal cil ndrica con un di metro de hasta 91,4 cm. (36 pulgadas) y longitudes de 15-15 metros (40-50 pies), se unen entre s hasta una longitud espec fica de obra. El tubo de revestimiento se calienta entonces hasta su temperatura de flexi n y se deforma gradualmente hasta un di metro reducido. En el lugar de obra, el tubo de revestimiento deformado se inserta en el tubo existente y se crea dentro un entorno de presi n controlada durante un periodo de tiempo dependiente de la longitud del tubo. En primer lugar se introduce vapor a presi n para proporcionar calor y presi n interna para expandir el tubo. Luego se introduce aire comprimido para enfriar el tubo, manteniendo al mismo tiempo la presi n interna para completar la expansi n y endurecer el tubo. Cuando se convierte a conducciones de continente doble, el tubo deformado tendr una pluralidad de espaciadores fijados por encima, para que los tubos existentes y deformados se alineen axialmente y tengan un espacio anular intermedio.
