Basel: Sanierung eines Betonkanals mit GFK-Sonderprofilen
02.03.2012
Nach 70 Betriebsjahren war der rund 1 km lange Entlastungskanal aus Beton in Basel-Stadt am Ende seiner Lebenszeit angelangt. Der Kanal mit dem Verlauf Leimgrubenweg-Walkeweg konnte durch punktuelle Reparaturen nicht mehr erhalten werden. Das Tiefbauamt des Kantons Basel-Stadt / Stadtentwässerung gab daher umfangreiche Analysen möglicher Sanierungsvarianten in Auftrag. Als beste Lösung mit zuverlässigem Betrieb und einer Lebensdauer von mindestens 50 Jahren ging daraus das GFK-Einzelrohr-Lining hervor. Im Zuge des Vergabeverfahrens stimmte das Tiefbauamt Basel-Stadt dem Vorschlag, Profile von HOBAS zu nutzen, zu.
