It is an object to provide a method of constructing an information correspondence pipe by easily laying a communications cable in an underground pipe line in the form of a main pipe with branch pipes, which underground pipe line can be used as an information correspondence pipe; a constructed structure; and a construction member. And the method of constructing an information correspondence pipe according to the invention comprises the steps of inserting a sheath pipe (1) into an underground pipe line (17, 7) through insertion holes (9, 10), which sheath pipe has a main body (3) formed with a space (2) for receiving a communications cable (6) and a high-strength low- stretchability material (4) integrally formed in the main body (3) along the direction of the length of the main body (3), fixing the high-strength low- stretchability material (4) to the inner walls of the insertion holes (9, 10) by applying tension thereto, and fixing the sheath pipe (1) substantially in the upper region of the underground pipe line (17, 7).

La présente invention concerne un procédé de construction de passages de câbles de communication facilitant le tirage du câble de communications dans une canalisation souterraine à tube principal et embranchements de façon que la canalisation souterraine puisse accueillir des passages de câbles de communication. L'invention concerne également une telle structure construite, et un module de construction. Pour la réalisation, on commence par passer un tube-gaine (1) dans une canalisation souterraine (17, 7) par des orifices d'introduction (9, 10). La forme du corps principal (3) du tube-gaine ménage un espace (2) permettant de passer un câble de communication (6) ainsi qu'un matériau hautement résistant et faiblement extensible (4) coulé dans le corps principal (3), en progressant dans le sens de la longueur du corps principal (3). On fixe ensuite le matériau hautement résistant et faiblement extensible (4) aux parois intérieures des orifices d'introduction (9, 10) en leur appliquant une tension. Il ne reste plus qu'à fixer le tube-gaine (1) sensiblement dans la zone supérieure de la canalisation souterraine (17, 7).
