Caisson tunnel, Oslo, Norway

The project:


Construction of a tunnel using caissons


Executing companies:

Skanska AS

Intec Pumper AS


The problem:


During construction of a tunnel with caissons, the individual elements had to be emptied after positioning. In addition, water flowing in along the segment had to be pumped out.


Our solution:


To pump larger quantities of water, pumps from the KTV series were used. Along the segment, model LSC pumps were installed. These flat suction pumps remove water above a residual level of 1mm, allowing work to proceed in as dry an environment as possible.

I tilfælde af slibende og ætsende anvendelse vil stærkere slitage forekomme naturligt i visse komponenter. Med hensyn til ovenstående anvendelse kan slitage hovedsageligt finde sted i pumpehjul, omrørerenhed, sugeplade, akselhylster, oliering, mekanisk tætning, pumpehus, si, motorhus og udløbskobling. Afhængigt af arbejdsvilkårene kan levetiden for disse dele variere betydeligt og kan være kortere end den lovlige garantiperiode.
I den forbindelse skal du være opmærksom på vores generelle vilkår og betingelser , som vi også sender til dig via mail på anmodning.
