Reinforced concrete retaining wall T-SHAPED WALLS

T-shaped walls require a foundation upstream and downstream of the panel, so the vertical face features openings for the main stabilization reinforcements. This type of wall is used above all when excavations have to be reduced upstream of the precast installation. Wall assembly To correctly install the wall, after project excavation, a concrete supporting surface will have to be made with a minimum thickness of 15 cm with an adequately reinforced Rck>=200, on which to erect the wall. In this transitory phase, the wall must be fixed to the supporting surface to ensure wind stability. On each base rib, the wall features shear bolt anchors to be fastened to the substructure. Now the stabilization reinforcement and linking beams can be installed before casting the stabilization base.
