This European Standard establishes general principles for the execution of diaphragm walls as either retaining walls or cut-off walls.
This standard covers only structures constructed in a trench excavated with a support fluid or in dry conditions, where soil is removed and replaced by concrete or slurry and with wall thickness B ≥ 40 cm.
Diaphragm walls can be permanent or temporary structures.
The following types of structure are considered:
-
retaining walls: usually constructed to support the sides of an excavation in the ground. They include:
-
cast in situ concrete diaphragm walls;
-
precast concrete diaphragm walls;
-
reinforced slurry walls;
-
-
cut-off walls: usually constructed to prevent migration of groundwater, clear or polluted, or of other contaminants present in the ground. They include:
-
slurry walls (possibly with membranes or sheet piles);
-
plastic concrete walls.
-
Walls formed shallow vertical trenches (typically excavations with a ratio of depth over thickness D/ B < 5 or D < 5 m) are not covered by this standard.
