Gotthard Basistunnel, Switzerland

The project:


Railway Tunnel Alptransit Gotthard,

Sedrun Section


Executing companies:

ARGE Transco Sedrun

Batigroup AG Tunnelbau,

Frutiger AG

Impresa Pizzarotti & C.S.p.


The "Sedrun Section" of the Gotthard Basistunnel encompasses two tunnels that are each 6,2 kilometres long and supplied through a 800m deep mine shaft. Two tunnels are at the base of the shaft and each breaks through to the north and south in the conventional manner.

The project tunnels through the unstable rock of the Tavetscher Zwischenmassiv with an up to 2.000m overlay. One of the two multifunctional sections of the 57 km long Gotthardbasis Tunnel is also being built in the Sedrun section.


The problem:


Pumping off the abrasive water that collects during the tunnelling excavations.


Our solution:


Use of the current 80+ Tsurumi wastewater submersible pumps for complete drainage. Pump series used: KTZ, KRS, KTV, LH, KRS with agitator.

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.
