摘要

Device for pumping water from great depths The invention relates to a device for pumping water from great depths, comprising a plurality of longitudinal elements (8) assembled together to form a pipe inside which circulates the water pumped from great depths, in which each longitudinal element (8) comprises a wall (10), for example of thickness less than or equal to 5 cm, forming a section of said pipe, said wall (10) being prestressed in tension, for example longitudinally and/or circumferentially, when water is not pumped through the pipe.
