Launching of San Pablo Bridge, Panama

 

Overview

ALE has successfully launched a steel bridge over San Pablo River in the city of Santiago de Veraguas, Panamá.

 

Services Required

 

The steel bridge weighed 800t. The bridge comprised of three spans, of 30m, 60m and 30m respectively. It was launched by using ten 90t skid shoes, two SLS700 strand jacks mounted on the abutment and eight 300t swivel plates mounted on the piles.

 

ALE concluded the manoeuvre by jacking the bridge deck, pile by pile. After launching the central 60m span, the next pile was reached with a deflection over 500mm. This was completely recovered only by the shape of the launching nose.

 

ALE completed the bridge launch in three days, working nine hours each day.
