CLOVER VILLAGE consists
of a residential building constructed within a rocky excavation 20m deep.
In winter times the exposed surfaces (about 1800m2) of
the rock cliff experienced spalling failures of rocks and cobbles that
jeopardized the safety of the residences below.
The
Soil is a fractured limestone formation.
I.G.M.
proposed a 15cm shotcrete wall at the top portion where the rock is highly
fractured, and a rock fall barrier with a galvanized wire mesh nailed to
the rocky surface. The distance between anchors is 1m with a length of
1.6m. The accessibility
during construction was extremely difficult, which renders the execution
of this project an important achievement.
