Groundwater tanks on B23 Saulgrub, Germany

The project:

City bypass for federal road B23 - 450m groundwater tank through the Saulgrub upland moor between Saulgrub and Unterammergau.


Executing company:

HOCHTIEF Infrastructure GmbH, Southeast Germany branch


Tsurumi consultants:

Mr. Christian Kulik (External sales force Bavaria)


The problem:

During implementation of the Saulgrub bypass, a 450m seciond of federal road B23 had to be taken through an underpass under the Murnau-Oberammergau railway. The area is permanently underwater, and ground and strata water also entered. Water retention using well pumps is essential.


The solution:

Open water retention using small, single-phase model HS2.75S wastewater pumps, controlled by float switches. Three-phase model KTV2-15 and KTV2-22 wastewater pumps run in 24-hour sip operation.

U slučaju abrazivnog i korozivnog korišćenja, u nekim komponentama može doći do prirodnog habanja. U pogledu gornje primene do habanja može doći pre svega kod rotora, agitatora, usisne ploče, rukavca vratila, uljanog prstena, mehaničke zaptivke, kućišta pumpe, sita, kućišta motora i ispusne spojnice. Radni vek ovih delova može znatno da varira zavisno od radnih uslova i može biti kraći od garantnog perioda.
U tom smislu obratite pažnju na naše opšte uslove korišćenja koje vam takođe na zahtev šaljemo poštom.
