The soil - cement panels, with UCS resistance not lesser
than 4MPa, were reinforced with vertical IPE330 steel profiles
(Euronorm 19-57), spaced 0,55m in average, in order to resist to
the earth and water pressures, as well as to ensure a better
control of the deformations. The steel profiles were placed
inside the panels, before the cement started the curing process
and capped by a reinforced concrete beam (Figure 8 to 11).

The soil - cement panels will be demolished from the
internal structure foundation level to the top, in order to allow
the reinforced concrete (r.c.) wall with a very good finishing
face, being visible from the adjacent marina, (Figure 12).

Solution type 2 (T2): soil - cement panels with a cross
section of 2,4 x 0,5m

, including 0,20m of overlapping on a
height of approximately 6.5m, correspondent to the previous
excavation depth, performed in order to replace the break water
rip rap by a sandy fill. The panels were built using the CSM
technology. Bellow the soil - cement panels the cofferdam cut
off effect was assured through a curtain, performed using
alternated slurry cement injections through steel tubes and
micropiles N80
114,3x12mm, those also with foundation
purposes and sealed 4m on the bed rock (Figures 12 to 15).
