Zusammenfassung:	The utility model discloses a steel corrugated culvert adopting both an end arc taper connecting mode and a longitudinal flange connecting mode. Arc tapers are arranged at the two ends of the steel corrugated culvert, one end is a positive angle inclination arc taper, the other end is a negative angle inclination arc taper of the same angle, the positive angle inclination arc taper of one steel corrugated culvert and the negative angle inclination arc taper of another steel corrugated culvert are arranged in an overlapped mode and fixedly connected through arc tapered bolts, and an arc tapered sealing gasket is arranged between the positive angle inclination arc taper and the negative angle inclination arc taper. The steel corrugated culvert comprises an upper semicircle and a lower semicircle, wherein the horizontal side of the upper semicircle is welded to an upper semi-circular flange, the horizontal side of the lower semicircle is welded to a lower semi-circular flange, the upper semi-circular flange and
