Abstract

L'invention concerne un procédé d'insertion de tuyaux dans des tuyaux de protection de câbles recouverts. Les tuyaux sont des tuyaux flexibles ou des câbles, destinés par exemple à l'insertion de câbles à fibres optiques. De tels tuyaux flexibles, mais également des cordons ou des petits dispositifs, doivent être placés de façon simple dans des tuyaux de protection de câbles déjà occupés par d'autres câbles ou conduites tubulaires. Cet objectif est atteint en ce que, dans une première étape, un adaptateur (4) est fixé au tuyau de protection de câbles (2) dans le puits d'entrée et le tuyau à placer est positionné dans ce tuyau de protection de câbles, le tuyau pouvant être ce que l'on appelle un Speed Pipe (23). Dans une deuxième étape, un blindage d'insertion (13) est placé et monté à l'extrémité du tuyau destinée à être insérée dans le tuyau de protection de câbles (2). Dans une troisième étape, un milieu fluide, de préférence de l'eau, s'écoule à travers l'adaptateur (4) jusque dans l'écran d'insertion (13) et transporte celui conjointement avec le tuyau vers le puits de sortie (12).
