North-tangent Dresden-Gorbitz, Bramschstraße tunnel, Germany
MAX BÖGL Group of companies
The tunnel lies in the ground water over its whole length. No free water table exists near the tunnel, the flow-in quantities depend on the distribution of the local flow quantities from top and vertical joints which extend as far as the main ground water course.
KTZ35.5 is used in 24-hour pumping on snore mode. Because cement sludge and abrasive media are pumped here it is necessary to apply a highly wear resistant pump.
