Syphon construction under nature reserve Löcknitztal by microtunnelling

The project:


Pipe heading DN 1600 by micro-tunnelling with reinforced concrete driving pipes for passing under the nature reserve Löcknitztal near Kienbaum (Land Brandenburg) as protective pipe for a high-pressure gas pipeline DN 1100.

Client:

Ruhrgas AG/Verbundnetz Gas AG

Executing company:

Gildemeister Tief-, Stahlbeton- und

Rohrleitungsbau GmbH&Co. KG Berlin


The problem:


Pumping off the supporting liquid (bentonite suspension) used in the tunnel during pipe heading.


Our solution:


Application of a submersible pump Type KTZ35.5 connected with an accompanying pipe line DN 100 for continuous removal of the supporting liquid during the whole time of pipe heading.

The pump was always positioned at the lowest point of the syphon and operated on snore mode.

U slučaju abrazivnih i korozivnih primjena, normalno je da će se u određenim komponentama dogoditi snažnije trošenje. S obzirom na gornju primjenu trošenje se može odvijati uglavnom u radnom kolu, miješalici, usisnoj ploči, rukavcu osovine, uljnom prstenu, mehaničkoj brtvi, kućištu pumpe, cjedilu, kućištu motora i ispusnoj spojki. Ovisno o radnim uvjetima vijek trajanja tih dijelova može značajno varirati i može biti kraći od pravnog zakonskog razdoblja.
S obzirom na to pridavajte pažnju našim općim uvjetima koje vam također šaljemo e-poštom na zahtjev.
