Following information collected over the years
and after a timely inspection carried out at the end of last year, together
with the highway manager we have defined a global maintenance intervention
aimed at restoring the correct functioning of the bearings and anti-seismic
restraints.
The intervention in progress consists in
restoring the planarity of the upper sliding plates and replacing them
where necessary for all the bearings, in addition to the complete restoration
of the anticorrosive protection, flashing cover replacement, application
of new identification labels of both the bearings and the retainers.
The intervention on the bearings involves
lifting on a single pile or simultaneous on multiple piles, adopting a
synchronized lift system equipped with electronic control of movements
and pressures.
In order to optimize movement and facilitate
access to the pulvins of the piles, a system of mobile suspended scaffolding
was installed that allows simultaneous access to three piles at a time
directly from the roadway.
All works will be carried out by our FPC
Italia technicians with the utmost respect for safety.
