FIELD: pipeline engineering.
SUBSTANCE: method comprises setting two coupling members around the sections of the pipeline to be repaired to define a space between the inner side of the coupling and outer side of the pipeline, tightening the coupling members to seal the coupling from the side of its faces, displacing water from the space, and filling the space with an expansible cement.
EFFECT: enhanced quality of repairing.
