Method for impeding transverse relative displacements of a pipe and at least one cable

A method for impeding transverse relative displacements of a pipe and at least one cable that extends in this pipe with a certain transverse play, the method comprising the steps of:

• selecting at least one portion of the pipe, said at least one portion having a predetermined longitudinal dimension;
• constructing at least one wedging element locally between the pipe and the cable inserted therein, said at least one wedging element adapted to suppress said transverse play in said at least one selected pipe portion;
• wherein the step of constructing said at least one wedging element is achieved by injecting a substance locally into the pipe in a flowable first state, the substance then solidifying into a non-flowable second state, said injecting comprising the steps of:
• disposing at least one duct in the pipe so that the duct has a near end situated outside the pipe and a remote end situated inside the pipe;
• disposing the cable in the pipe by inserting a plurality of strands in the pipe to define a bundle having a predetermined number of the strands, which bundle comprises the cable;
• after disposing the plurality of strands in the pipe, adjusting the position of the remote end of the duct in the pipe, such that the remote end of the duct is in a selected portion of the pipe to constitute the wedging element;
• and
• injecting said substance into the duct from the near end thereof, such that the substance comes out of the duct at the remote end until the wedging element is formed.
