FIELD: construction.
SUBSTANCE: invention relates to construction of culverts in intersection areas by main pipelines of watercourses. Culvert under embankment contains set of concrete slabs laid along profile of stream channel profile, under waterproof perforated cloth made of non-woven synthetic material (NSM) placed on pile with working tube, laid on top of concrete slabs. Bottom and side plates are sealed, and top plates are laid across channel directly to side walls without sealing. With width of water mirror from 5 to 10 m, upper plates are laid along channel on beams located on side plates with calculated step across stream bed.
EFFECT: technical result is increase in operational reliability of pipeline by eliminating watercourse impact.
