CULVERT STRUCTURE WITH THE USE OF ROD STRUCTURES OF MULTIFACETED STRUCTURE Russian patent published in 2023 - IPC E01F5/00 E01C3/06 

FIELD: transport construction.

SUBSTANCE: invention can be used in the construction and reconstruction of subgrade railways and roads. The culvert with the use of bar structures of a multifaceted structure is located on a crushed stone base, holding it in the design position, crosses the subgrade of the embankment in the transverse direction and consists of bar structures of a multifaceted structure in the form of an octahedron adjacent to each other, sequentially laid along the axis of the structure, the main elements of which are tubular rods, which are beams with a given cross section and perform the functions of structural ribs, and nozzle caps, made in the form of a ball with holes for fastening the rods, performing the functions of structural nodes. A protective layer of text concrete was laid on the upper and side surfaces of the culvert part of the structure from the side of the embankment.

EFFECT: improved culvert properties of the structure in the body of the subgrade of the embankment.
