FIELD: construction.
SUBSTANCE: steel pipe with an anticorrosive coating is installed on the assembly stand. Along its surface, a reinforcing cage is constructed, consisting of longitudinal and annular reinforcement bars. On the frame the cable-conduit is placed in the form of a protective tube. The tube is placed in a mould and a concrete mix is poured into the space between the tube and the mould. After the concrete strength is set, the tube is removed from the mould.
EFFECT: high reliability associated with the placement of the cable-conduit in the thickness of the concrete coating of the pipeline and the technology of its fastening.
