Parisian wall

The Lutetian wall is a shoring wall derived from the Berliner wall. In between the vertical components (steel H beams), and unlike Berlin-type walls, these types of shoring walls receive lightly reinforced shotcrete walls instead of horizontal sheeting.

Construction sequence

1. Formation of the reinforced concrete cast-in-place bored pile or drilling of a borehole for the placement of the a steel profile.

2. At the first phase of the earthwork, projection of lightly reinforced shotcrete.

Eventual anchoring of the wall.

3. & 4. At the final phase of the earthwork, termination of the application of the shotcrete.

Construction chart

Fields of application

• Earth retaining wall, without groundwater over the retained height in the excavation area

• Not water retaining (the wall is permeable)

Environmental impact

• Soil removal: depending on the construction process

• Vibration and noise pollution, depending on the construction process

• A stable, dry and flat work platform is needed

• Specific measures during the application and projection of the concrete

Technical specifications

• Only earth retaining in temporary phase

• Applicable only if the groundwater level is lower than the maximum excavation level (temporary or permanent conditions)

• Temporary cohesion of the soil is needed in order to carry out the excavation and allow for the placement of the shotcrete or pneumatically projected concrete at high velocity.

• Soil removal: depending on the construction process

• If required, installation of additional anchors

• Depth: see the section of the “large diameter bored piles”

• Height: limited only by the level of the groundwater table

• Width: equal to the diameter of the chosen pile
