    摘要: Reinforcing cage for the wall of a concrete pipe characterized by a pair of helical spaced coils, indexed 180* apart, and longitudinal members woven over and under adjacent coils and mechanically locked thereto, said members being disposed angularly to the planes of the ends of the cage, forming isosceles triangles for resisting torsion in both directions about the cage axis, together with method of making the cage. Various additional optional features may be employed.
