as well as the reduction of the soil nails quantity
defined in the natural slopes, translated into an
economy for this type of works of about 1200 m,
corresponding to 14% of the previewed total.
During the works execution six natural water
storage galleries were found, from which only two
had already been identified but without any sur-
vey being made due to the dense vegetation cover.
a detailed study was made to each one of these
galleries with the purpose to develop solutions that
could guarantee their stabilization in order to inte-
grate them in the resort, as an attraction point. in
some cases there was the need to make some archi-
tectural adjustments, in others it was necessary to
full fill with cyclopean concrete.
The water storage gallery detected in the resort
southern zone, near the existent reservoir, located
under a landfill retaining wall and under a dwelling
sized due its importance and size.
To allow future visits to the gallery its reinforce-
ment was analyzed, having as basis the need to
keep the n5 block's definition unchanged.
hence, a solution of columns in reinforced con-
crete was executed to support the landfills nec-
essary for the dwellings platforms, as well as to
support the retaining structure which foundations,
in the entrance area of the detected gallery, had
in the gallery east zone, due to the proximity
with the retaining structures foundations, 3 steel
micropiles were executed. in the west zone, where
the wall was on the alignment of one of the gallery
cavities, a cyclopead concrete fill was made in this
“corridor”, along of the wall width.
