PROTECTIVE STRUCTURE OF A ROAD PASSAGE THROUGH HOSE PIPELINES, A SECTIONAL CONNECTION UNIT AND A METHOD FOR PROTECTING HOSE PIPELINES Russian patent published in 2022 - IPC E01C9/00 F16L7/00 

FIELD: safety structures.

SUBSTANCE: roadway guard protecting pipelines running over the roadway across traffic is comprised of a plurality of interconnected modules. The module contains a section of the central channel, sections of the entrance and exit of the vehicle, typesetting sections located between the sections of the central channel and the entrance or exit. The section of the central channel contains internal compartments, which are closed with a hinged cover, which is mounted on supports, forming a span of the bridge over the compartments, and is made with the possibility of tilting. The sections are connected by means of pivotally arranged collapsible connection units. The assembly contains connecting elements of sections in the form of pipes adapted for insertion into each other with a gap for connecting and fixing sections to the module, and a fixing connecting element in the form of a plate with holes that are adapted to receive section pipes and fix sections of neighboring modules. A plurality of sections are connected by inserting connecting elements in the form of pipes and plate holes into each other, and the protected pipelines are placed in the inner compartments of the sections of the central channel, which formed channels for receiving pipelines across the carriageway, and subsequent closing of all covers.

EFFECT: invention is designed to protect the hose pipelines passing over the carriageway from damage by vehicles, provides quick access to the pipelines, fast and economical installation and normal traffic of vehicles as a roadway.
