FIELD: hydraulic and irrigation building, particularly bank protective structures used to consolidate beds of rivers and channels, dam slopes and other structures. ^ SUBSTANCE: transversal through bank-protection device comprises composite stay members forming prism. Each composite stay member includes protective coating, filling material and wire placed in the coating. The composite stay members are assembled to define triangles by twisting together wire ends of stay member about transversal reinforcement so that triangular or trapezoid prism joints are created. Triangular or trapezoid prism has cross-section forming triangular or trapezoid truss. Prism is installed at an angle to flow direction and abuts river bed by one prism face. Prism interior may be filled with bushes. ^ EFFECT: increased efficiency and reliability of bank protection against erosion, increased service life. ^ 2 cl, 8 dwg |
