FIELD: hydraulic and reclamation construction, particularly bank consolidation structures to protect river banks, dam slopes and other structures.

SUBSTANCE: flexible retaining wall has prismatic structure and includes stone, net and trusses of stable triangular shape. Flexible retaining wall cross-section defines triangular trusses composed of spacing members. Each spacing member is formed of protective concrete in which wire is embedded. The spacing members are united in triangle assemblies by twisting spacing member wire ends around transversal reinforcement bars so that triangular prism nodes are created. Triangular prism is provided with one reinforced concrete face formed of net and concrete and located from upstream prism side. Triangular prism interior is filled with stone. The triangular prism is laid in longitudinal river direction and abut river bottom by one face thereof. Upper wall slope may be vertical or extend at an angle to horizon line.
