CULVERT STRUCTURE IN REINFORCED GROUND CASE Russian patent published in 2006 - IPC E01F5/00 

FIELD: transport building, particularly large-scale artificial building structures, overpasses, railroad and motor road embankments, avalanche protective galleries, urban and countryside building structures, to construct and repair bridges in most climatic zones characterized by ambient temperature of +50° - -50°.

SUBSTANCE: culvert structure comprises tube formed of steel corrugated zinc-coated sections bent round a predetermined radius. The sections are overlapped and connected with spherical support structure by bolts and nuts. The support structure rests upon profiled base bed. The tube comprises damping layer and reinforced ground case formed of several layers of compacted ground having constant thickness of not less than 500 mm, corrugated structure expanding in direction from surface and smoothly passing into embankment.

EFFECT: reduced material consumption and labor inputs for structure erection, improved adaptability to variable ground and temperature conditions, increased vibration and seismic stability, increased speed of structure mounting along with provision of necessary structure strength, stability and service life.
