  on under water bridge columns


Constructed in the 1940s, the columns of the Arstein Bridge in Northern NorwaConstructed in the 1940s, the columns of the Arstein Bridge in Northern Norway had suffered excessive degradation of the concrete and steel reinforcement, particularly in the splash zone.

The concrete, single carriageway bridge includes 11 pairs of columns. Each pair of columns is joined at a low level, but above water, by a crosshead beam.

Below the beam, the columns are 1500 mm diameter and above the beam to the underside of the bridge deck reduce to 1000 mm.

The Norwegian contractor, Multibetong, appointed UK contractors Rentajet Group (RGL) to undertake the specified removal of all growth from around the columns, and any damaged concrete below the crosshead beam down to the Fjord bed level, a depth of approximately 16 m.

The columns were prepared ready for stainless steel reinforcement to be fixed prior to reinstatement of a new concrete case.

The depth of damaged concrete ranged between 25 – 150 mm and in total more than 1500 m² was treated.

RGL used a new Aqua Spine system from Aquajet Systems together with a bespoke 1500 mm diameter pile ring multi-modular frame system with special clamp legs to fix to the column.
