摘要:

本文利用连续碳纤维的电热性和高强性,把连续碳纤维铺放在混凝土中,研制出具有融雪功能的电热混凝土路板,提出在混凝土中铺设“加热带”,而非整个路面全部加热的思路,达到减少制造成本的目的。确定了“加热带”宽为500mm,碳纤维到混凝土表面距离为15~20mm,碳纤维束的间距为12mm,最大设计功率设定为700W/m2。进行缩比样实验,实验结果表明,电热混凝土板加热均匀,升温速度适当,在-13℃左右、风速较低的情况下采用200~300W/m2的输入功率可使所降的中雪落地即融化。

Abstract:

The snowmelting concrete road panels were studied by laying highstrength continuous carbon fiber with good electric properties in the concrete.To lower the cost,“the heating tapes” were laid in the concrete rather than to heat the whole road.“A heating tape” is 500mm wide,the distance of carbon fibers is 15~20mm to the surface of concrete,the spacing among carbon fibers bundles is 12mm,and the maximum design power is set in 700W/m2.The test results show that the moderate snow can be melt immediately at -13℃ and lowspeed wind when the input power is 200~300W/m2, if the concrete panel is heatedelectrically uniformly at a proper elevatedtemperature speed.
