Tunnel Weißenburger Street, Dortmund

The Project:

Construction of an underground railway tunnel with a length of 130 m, descending heading with a partial cut machine.

Executing company:

ARGE Tunnel Weißenburger Straße, Dortmund

Wiemer & Trachte AG

Alpine Bau Deutschland GmbH

The Problem:

Drainage during the tunnel heading work.

Our Solution:

Use of submersible pumps of the KTZ series which can reliably ensure drainage in 24-hour snore mode during the heading work.

In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, agitator, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
In this regard, please pay attention to our general terms and conditions that we also send to you by mail on request.
