Loithal Bridge corrosion solution
The Loithal Bridge on the Salzburg-Munich A8 autobahn in Germany suffered severe corrosion problems on the parapet beams and hardshoulders caused by deicing salts. Hochdruck Industrie Service GmbH was awarded the contract for hydrodemolition on the bridge in a two-month contract. Two hydrodemolition Aqua Cutter HVE Evolution robots from Sweden's Aquajet Systems were used. Water is blasted at extremely high pressure into the concrete. The robots are operated either through a wireless or a lightweight hardwired system. The operator can vary the angle of penetration, the lance speed and the degree of oscillation. The robot cleans the concrete and base underneath, leaving a craggy bonding surface. The robots are supported in a gantry and steel surface preparation deck covering the complete width of the autobahn.(A)
