The Project:
The Bibra Tunnel is part of the German Unity construction project No. 8, the extension stretch on the route Nuremberg-Erfurt-Leipzig-Halle- Berlin.
Company involved:
Marti Tunnelbau Bunte
The Problem:
Maintaining water clearance by means of submersible pumps at the tunnel portals and during the tunnel advance.
The Solution:
Use of Tsurumi dirty water submersible pumps of widely differing types to remove water from the tunnel. Thanks to their tough, robust design, and the special internally-located slide-ring seal, Tsurumi pumps can be kept permanently in operation in "on-snore-mode".
