|Structural repair and maintenance has always
been a key activity of Freyssinet Products Company Italia, also to support
the application of structural bearings, antiseismic devices and joints
on the existing structures.
The following are the main activities performed for the maintenance or retrofitting of the structures:
• Lifting of bridge spans from top or bottom
In all these cases a deep analysis of the
structure to be repaired is necessary as well as the eventual design of
ad-hoc equipment to be utilized to prevent any damage to the structure
during the interim phases and to allow a safe execution of the work. By
use of modern electronic and oil hydraulic devices the most sensitive operations
can be performed with remote control through dedicated PC and software.
Among the most important repair works executed in the past, we can mention the repair of the Polcevera Bridge in Genova. This bridge is an hystorical structure, designed by Prof. Riccardo Morandi in the years sixties. The repair involved the application of external stay cables, the installation of several components in steel carpentry and the repair of the damaged concrete.
