Abstract

Procédé pour supporter ou envelopper une canalisation sous-marine en formant une structure de béton en contact avec la canalisation dans la position désirée. On place un sac imperméable flexible au voisinage de la canalisation. On relie le sac à une source de béton liquide. On remplit le sac de béton à l'état liquide, jusqu'à ce que le sac prenne les dimensions et la forme désirées au contact de la canalisation. On laisse alors prendre le béton Applications à la pose et à l'entretien des canalisations à longue distance, notamment pour le pétrole.A method of supporting or enveloping an underwater pipeline by forming a concrete structure in contact with the pipeline in the desired position. A flexible waterproof bag is placed in the vicinity of the pipe. The bag is connected to a source of liquid concrete. The bag is filled with concrete in the liquid state, until the bag takes the desired dimensions and shape in contact with the pipe. The concrete is then allowed to set. Applications in the laying and maintenance of long-distance pipelines, in particular for petroleum.
