Erste Leerrohre für Süd-Ost-Link liegen nahe Nabburg bereits unter der Erde

Die ersten Leerrohre für die Höchstspannungs-Gleichstromleitung Süd-Ost-Link liegen bei Obersteinbach (Stadt Nabburg) bereits unter der Erde. Wie funktioniert die "geschlossene Bauweise"?

von Clemens Hösamer

Mit dem Spülbohrgerät (links) wird das Gestänge (im Vordergrund) horizontal unterirdisch vorangetrieben. Bei Obersteinbach werden so über 200 Meter Länge in bis zu 11 Meter Tiefe überwunden. Im Lkw rechts wird unter anderem die Spülflüssigkeit vorbereitet.
