V-shaped cable trough channel for railway lines

摘要

The V-shaped concrete cable trough channel for accommodating cables of minimal diameter for overriding use in railway installations is described. The downwards V-shape and the minimal dimensions allow the cabling in a groove made with an auxiliary device without shaft work to make a special cable bed. The cable trough channel has a minimal space requirement. Its inside lids (2) run slightly conically downwards, whereby a rigid seat is improved and a sealing band can be done without. Its inside lids as a result of the minimal lid thickness turn out thinner, easier, and more material saving. The connecting points of the lower parts are laid in a sealing and adjusting plastic sleeve (4) which is open upwards.
