FIELD: laying underwater pipe lines. SUBSTANCE: pipe line to be laid through water obstacle is made as double- pipe with inter-pipe space filled with chemical reagent- oligoorgano ethoxyl chlorosiloxane. In case of damage to outer pipe, chemical reagent reacts with water entering the inter-pipe spaced and forming infusible insoluble polyorganosiloxane polymer, thus restoring tightness of outer pipe. EFFECT: enhanced efficiency.
