Bajo el fondo del mar, a decenas de metros de profundidad, hay una obra que avanza con un margen de error m\u00ednimo. No se ve desde la superficie, pero forma parte de una infraestructura ferroviaria clave en el sur de China. Seg\u00fan CGTN, el pa\u00eds ha alcanzado un nuevo hito en la construcci\u00f3n de un t\u00fanel submarino para alta velocidad: la excavaci\u00f3n ya ha llegado a los 113 metros bajo el lecho marino. La cifra no es menor, porque sit\u00faa la obra en un punto donde las condiciones geol\u00f3gicas y la presi\u00f3n del agua elevan de forma notable la dificultad t\u00e9cnica.<\/p>\n\n\n\n
Ese avance forma parte de una infraestructura mucho mayor que est\u00e1 tomando forma en el sur del pa\u00eds. La l\u00ednea de alta velocidad Shenzhen-Jiangmen, de 116 kil\u00f3metros, est\u00e1 dise\u00f1ada para conectar ambas ciudades en menos de una hora, integr\u00e1ndose en el corredor ferroviario que recorre la costa china. De esta forma, el proyecto ha entrado en una fase especialmente exigente, en la que el t\u00fanel bajo el estuario del r\u00edo Perla se convierte en uno de los puntos t\u00e9cnicamente m\u00e1s complejos de toda la obra.<\/p>\n\n\n\n
Un tramo bajo el mar que concentra el mayor desaf\u00edo t\u00e9cnico
En el centro de esta fase del proyecto se encuentra la infraestructura submarina que obliga a afinar cada paso. Para ejecutarla, la obra se apoya en una tuneladora de gran di\u00e1metro desarrollada en China. La m\u00e1quina, conocida como \u201cShenjiang-1\u201d, ha mantenido la excavaci\u00f3n en marcha de forma continua, incluso durante periodos festivos como el Qingming. No solo perfora el terreno, tambi\u00e9n permite avanzar mientras se construye el revestimiento interior del t\u00fanel, un sistema con el que se busca ganar eficiencia en uno de los puntos m\u00e1s delicados del recorrido.<\/p>\n","protected":false},"excerpt":{"rendered":"
