  • Method for laying a plurality of successive sections of cables in order to form a cabled connection of great length
    Patent number: 9287689
    Abstract: A method for laying a plurality of cable sections to be successively positioned in series in a buried duct, according to a flowing-pushing method using a pressurized fluid. The different cable sections are successively introduced into the duct in a single entry point comprising a laying device notably comprising an orifice for introducing a pressurized fluid, a cable section entirely introduced into the duct is pushed towards the position which it should occupy in the duct, only by the pressure of the fluid introduced by said laying device and when a cable section has reached his final position in the duct, an opening is made in the duct near to the rear of the cable section.
