Incremental Launching Bridges
This is a deck construction process that involves the manufacture of deck sections (segments) in a fixed location (Manufacturing Park). Each section is then launched with hydraulic jacks passing through the top of the piers with special support elements.
This process is repeated as many times as the number of deck segments or sections, fixing them together with the post-tensioning operations.
The launching equipment includes horizontal and vertical hydraulic jacks, so that the movement takes place in four phases, whereby the vertical jack lifts the platforms load and it is then pushed by the horizontal jack to move the platform forward. After covering approximately 20 cm, the vertical jack is lowered and the horizontal jack is retracted, repeating the cycle.
