| Métodos para inspeccionar y reparar conductos plásticos subterráneos |
Una vez instalado un conducto en una zanja rellenada, pero antes de iniciarse la construcción de superficie, suele verificarse la calidad del conducto, pues determinados conductos de plástico pueden ovalarse, agujerearse o romperse. En la Recomendación UIT-T L.73 se describen métodos de inspección, como la utilización de ejes de prueba y sistemas de televisión en circuito cerrado (CCTV) para verificar la calidad de los conductos; y se describen además varios de los métodos utilizados para reparar los conductos subterráneos. Se presentan métodos de reparación sin excavación, denominados "técnicas sin zanja", y métodos de reparación tradicionales (excavar y reemplazar). Además, se proponen directrices para la selección del método de reparación adecuado. Se prevé que esta Recomendación ofrezca soluciones alternativas para los trabajos de inspección y reparación. |
