Incremental launching methodology
For the launching operation special “friction system” using hydraulic lift-push jacks is used. Alternatively, the launching can be done by means of hydraulic pulling jacks using strand or bar temporary tendons. A steel nose is installed on concrete viaducts or a temporary tower with stays on metallic decks.
