Blown out 2,000 cubic meters hydro granules
The reason for the explosion of the one during Skeggestadbroene on E18 in Vestfold is that a quick clay slides made bridge collapsed almost three weeks ago.
– We have published 2,000 cubic meters of loose hydro granules under the bridge. These are blown into the area with a hose that is controlled by a robot, said project manager in the Public Roads Administration, Arvid Veseth, TV 2 before the blast.
Leca spheres should curb impact from concrete parts when the bridge rupture and protect pillars and foundation of the neighboring bridge.
– It soon became clear that it was important to get it down quickly, so it does not moved toward neighboring bridge and did damage to columns or foundation there.
Two homes evacuated
It was created a security zone around the bridges that vary from 350 to 500 meters, and two residences located within this zone is evacuated.
– It will also hung a veil down from the bridge and past the columns that will receive the spray from the blast, said Veseth.
