<p>The subject of the invention is a buried pipe consisting of a series of segments placed one after the other, and each including a lower part resting on a laying surface (A) and an upper part consisting of at least one element (2) forming a roof and resting on the lower part via longitudinal bearing members (7) (7') parallel to the longitudinal axis (0). According to the invention, the lower part of each section of the pipe (1) consists of two prefabricated bearing elements (30), each forming an isolated base (32), the said bearing elements (30) being placed one after another so as to form two longitudinal bearing members (7, 7') on which the lower side edges (71) of the upper elements (2) come to bear.
