Have in the asphalt pavement structure of automatic snow melting function above-mentioned, the outer race of described snow melt pipe has heat radiation protection pipe, forms the annular space stored for cooling fluid between described snow melt pipe and heat radiation protection pipe.Heat radiation protection pipe both had protective effect to snow melt pipe, strengthened again the effect of heat radiation, was beneficial to snow melt.
Have in the asphalt pavement structure of automatic snow melting function above-mentioned, be provided with radial strut between described snow melt pipe and heat radiation protection pipe, described radial strut is axially uniformly distributed along snow melt pipe.Radial strut plays radial support effect, is beneficial to stabilized structure.
Have in the asphalt pavement structure of automatic snow melting function above-mentioned, being connected by swan-neck between adjacent snow melt pipe forms bending snow melt house steward, and the both ends open of described bending snow melt house steward is connected by transverse connecting pipe.Bending snow melt house steward is finished up and is mutually formed a circulation line.
Have in the asphalt pavement structure of automatic snow melting function above-mentioned, described drainage channel comprises the longitudinal drainage passage along drainage blanket cross direction profiles and the transverse drainage passage along drainage blanket genesis analysis, the intersection of described transverse drainage passage and longitudinal drainage passage forms right-angled intersection portion, is provided with screen pack in described right-angled intersection portion.Screen pack has filtration to impurity.
Compared with prior art; the advantage originally with the asphalt pavement structure of automatic snow melting function is: first; heater is started by gauge tap; anti-icing fluid in heating snow melt pipe; anti-icing fluid transfers heat to topping; make snow melting; snow-broth after thawing enters into topping by inlet opening, then enters into drainage channel by communicating pipe, finally flow into snow-broth gathering-device; snow-broth is avoided to scatter everywhere; be beneficial to road surface clean and tidy, snow melt efficiency is high, and global design is reasonable; structure is simple, practical.The second, heat radiation protection pipe both had protective effect to snow melt pipe, strengthened again the effect of heat radiation, was beneficial to snow melt.3rd, radial strut plays radial support effect, is beneficial to stabilized structure.4th, screen pack has filtration to impurity.
