Steel formwork for Caisson Walls
| The steel formwork of the walls measured
18.30 X 9.15 X 1.00, was manufactured in Italy and was imported to Greece
unmounted (its mounting was done in situ). The working deck was created by placing planks on top of the cells. |
| In the middle of each cell's deck, grids were placed in order to facilitate concrete construction of the base and cleaning during concrete construction of the walls. |
| In the meantime, in the perimeter of the walls, a working deck was hung for the slight repairs of the walls and the removal of the hole-patterns of the absorbent front. |
Concrete Construction - Lining of the Caisson Walls
The most
complicated part in the construction of caissons was concrete construction
of the walls, which included simultaneous concrete construction and lifting
of the steel formwork.
The lifting of the steel formwork was done through a hydraulic system installed
on the working deck. Simultaneously with the concrete construction, the
draft of the floating platfrom ("Benedetta") was increasing.
