FIELD: road building, particularly structures for storm and melted ice water passage.
SUBSTANCE: method involves mounting tube including several semi-rings installed on foundation blocks at bottom slope edge of embankment. Semi-rings are conical and arranged so that semi-ring bases having greater diameters extend beyond upper embankment slope edge. Lengths of extended semi-ring parts are more or equal to the smaller distance between extended semi-ring edge to semi-ring center of gravity in horizontal direction.
EFFECT: increased service life.
