Description

The invention relates to electrical engineering and can be used in the construction of railways for laying cable communications on the stage for ballastless structure of the railway track.
In the well-known ballastless T-Track system, when pouring ballastless forms, plastic tubes are laid in molded modules for mounting fiber-optic communication lines, which eliminates the need for channels and trenches for laying communication cables (hencon.ru> images / t-track / TUBULAR_TRACK_2017 .pdf).
It is known that during the construction of a ballastless path on each side of the neck of the rail, routes are laid for laying the cable in the form of pipes made of rigid polyvinyl chloride, one pipe on each side. Pipes are made with corresponding notches (National Association of Builders, Organization Standard “Railways. The upper structure of ballastless railway. Rules, control of implementation and requirements for the results of work”, STO NOSTROY 137, Project, first edition, North-West Limited Liability Company Scientific Information and Consulting Center ”(LLC“ SZNIKTS ”), 2013,
p. 87, https://www.moozs.ru/file/raznoe/obs_std_nostroy/STO_137_verhnee_stro en_bezbalastnoe_1_red.pdf).
The closest analogue is a system for laying cable communications with a ballastless construction of the track, in which the routes for laying cable communications are placed on both sides of the track, each of which is made of concrete in the form of a gutter, covered with a lid, and is integral with the basis of the ballastless path (US 2008315002 A1, Е01В 1/00, Е01В 2/00, E01D 19/12, 25.12.2008).
In accordance with the established requirements imposed by special technical conditions, not only signaling and signaling and communication cables, but also power cables and cables of an integrated security system are laid on a high-speed highway.
However, the known systems do not allow the joint laying of communication cables with power cables and power cables, an integrated security system.

For the organization of cable transitions of signaling and signaling channels, the route for laying signaling and signaling devices for interfacing with adapter wells includes passage channels connected to it, each of which is made of respective passage trays or pipes.
