Embodiment Construction
[0039] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0040] In this embodiment, the method for manufacturing the circumferential connecting flange of the corrugated steel pipe includes the following steps:
[0041] (1) The reserved section 14 of the corrugated steel plate 1 is cut obliquely from the crest 11 to the end of the wave waist 12, and the trough 13 of the corrugated steel plate 1 is continuous.
[0042] The arc-shaped corrugated steel plate can be arc-shaped corrugation in the form of a sinusoidal curve, including a semicircular-like crest 11 , a wave waist 12 similar to a straight line, and a trough 13 with the same shape as the crest and opposite direction. A section of length is reserved on the corrugated end of the corrugated steel plate (the end is the side perpendicular to the corrugated direction of the corrugated steel plate) as the height of the corrugated flange, and the peak...
