Arched culvert pipes under the road embankment in permafrost

摘要

The invention relates to the field of construction, in particular, to the field of construction of culverts under roads.; Arched culvert under a road embankment in permafrost zone comprises from corrugated metal arch structures. Fundam formed concrete.; The novelty of the proposed utility model is that the foundation is made of three or more layers of corrugated metal sheets with corrugations oriented transversely to the longitudinal axis of the arch with a rigid and tight connection to each other according to the scheme when one adjacent layer of specularly reflects another relative contiguity plane and heel arch is rigidly attached to the foundation, the cavity formed by splicing the corrugated sheets foundation filled with polystyrene foam. The top layer is made of corrugated sheet bases uniform for both the bases and disposed horizontally, and the space under that sheet between adjacent foundations nepuchinistym filled with soil.; The proposed design allows mounting multigrade dramatically simplifies installation conditions and transporting structures, and during operation maintains the frost in the ground, wherein the insulation itself is under high security.; 2 n.
