CEN - EN 1538

Execution of special geotechnical work - Diaphragm walls

active, Most Current
Organization: CEN
Publication Date: 1 September 2010
Status: active
Page Count: 52
ICS Code (Earthworks. Excavations. Foundation construction. Underground works): 93.020
scope:

This European Standard establishes general principles for the execution of diaphragm walls as either retaining walls or cut-off walls.

NOTE 1 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.

NOTE 2 Diaphragm walls can be permanent or temporary structures.

NOTE 3 The following types of structure are considered:

a) retaining walls: usually constructed to support the sides of an excavation in the ground. They include:

1) cast in situ concrete diaphragm walls;

2) precast concrete diaphragm walls;

3) reinforced slurry walls;

b) cut-off walls: usually constructed to prevent migration of groundwater, clear or polluted, or of other contaminants present in the ground. They include:

1) slurry walls (possibly with membranes or sheet piles);

2) plastic concrete walls.

NOTE 4 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.
