The Berlin-Wall temporary shoring system has become a widely adopted technique providing an economic, fast, safe and
reliable method to retain the sides of projects with deep excavations.
The Berlin Walls system is considered
|
-
Economic because its cost is much cheaper than Diaphragm walls.
|
-
Fast because it does not consume much time during installation like secant piles walls, besides it can be undertaken
simultaneously during / with the excavation process.
|
-
Safe because it does not cause excessive vibrating / driving problems like steel sheet pile walls.
|
-
Reliable because it can safely retain the
required depths / sides of excavations for as
long as the project may require.
|
The application of the Berlin-Wall is specially feasible when the lowering of ground water table
is not a critical factor. But in case lowering of
ground water table outside the excavation pit is to
be minimized, other shoring systems would seem better
suited, feasible and recommended (such as
Secant piles walls
or
Diaphragm walls
).
