Steel sheet-pile wall was planned for construction at first.  But it proved itself not sufficient for securing excavation wall stiffness. It was planned to construct additionally horizontal diaphragm wall at the depth of 12-14 m with jet-grouting method to provide sheet-pile wall stiffness. Even in this case analysis proved that settlements could be dangerous for the buildings nearby.  Thus it was suggested to construct outside the sheet-pile wall a vertical reinforced concrete-soil diaphragm wall with jet-grouting method with a length of 18 m and width of 1 m app. Then previously constructed steel sheet-pile wall and concrete-soil wall were to be joined together with a single reinforced concrete beam.
