super high Connections has the task of transforming an air conditioner from the usual cross section of two roof into a special cross-sectional super high.
When Vtt = 20 ÷ 40 km / h, then if = 1%. - When Vtt ≥ 60 km / h, then if = 0.5%.
Prior to connecting segments ultrahigh need a 10m long section to increase the margin with slope equal horizontal slope pavement, sidewalk own land without reinforcement the back curve is still steep curve toward the back. Ultrahigh connecting segments, connecting segments are arranged expand coincides with forward curve.
