Culvert in a road embankment on permafrost

摘要

The utility model relates to the field of construction of culverts and can be used in the construction of culverts under embankments of railways and roads in areas of permafrost soils with high snow tolerance. The culvert includes a culvert (1), and the inlet and outlet heads, shells (6), made in proportion to the end links of the culvert, coaxially placed, and cantileverly fixed to the end links, with a gap relative to the soil base of the road embankment, while the length of the shells is determined according to the claimed formula. The design is simple to manufacture, provides the required level of operational reliability, extends the service life. 1 ill.
