A method for forming a barrier in a subterranean formation is described comprising connecting two pipes to each other by a tensile member, cutting a continuous path through the subterranean formation with the pipes and tensile member, and providing grout into the path. An apparatus for forming such a barrier is described comprising a tensile member, at least two pipes wherein the pipes are connected to the tensile member wherein the pipes are configured to deliver grout to the subterranean formation, and at least one drilling apparatus wherein the drilling apparatus, pipes, and cable are configured to cut a path through the subterranean formation.

La présente invention concerne un procédé de formation d'une barrière dans une formation souterraine comprenant le raccordement de deux conduites par un élément résistant, le découpage d'un passage continu à travers la formation souterraine avec les conduites et l'élément résistant, et la fourniture d'un coulis dans le passage. L'invention concerne également un appareil pour la formation d'une telle barrière comportant un élément résistant, au moins deux conduites, les conduites étant raccordées à l'élément résistant et étant configurées pour alimenter le coulis à la formation souterraine, et au moins un appareil de forage, l'appareil de forage, les conduites, et un câble étant configurés pour découper un passage à travers la formation souterraine.
