【摘要】：为研究布置连续式碳纤维线的自发热机场混凝土道面的融雪化冰规律,制作了内设6K、12K、24K发热线的水泥混凝土板,展开不同功率、不同厚度等条件下的室外融雪化冰试验,并进行了机理分析。结果表明,1在板内设置隔热层可以减少混凝土板的蓄热量,提高融雪化冰的效率;2输入功率和冰雪厚是决定融雪时间以及耗电量的主要因素,一定范围内,功率每增加50W/m2,化雪时间缩短1.14h,节省电量0.25k W·h/m2,雪厚每增加1cm,化雪时间延长0.69h,耗电量增加0.35k W·h/m2;3对道面进行提前预热不仅可以避免道面积雪,而且通过采用间歇式供电可以节约能耗。
[Abstract]:In order to study the snowmelt ice melting law of spontaneous hot airport concrete pavement with continuous carbon fiber line, the cement concrete slabs with 6K, 12K and 24K hotlines were made, and the outdoor snowmelt ice melting tests under different power and thickness were carried out, and the mechanism was analyzed. The results show that: (1) the heat storage of concrete slabs can be reduced and the efficiency of snowmelt ice melting can be improved by setting heat insulation layer in the slabs. (2) the input power and ice and snow thickness are the main factors that determine the melting snow time and power consumption. In a certain range, the snow melting time is shortened by 1.14 h, the power saving is 0.25 kW 路h / m2, and the snow melting time is prolonged by 0.69 h and the power consumption is increased by 0.35 kW 路h / m2 with the increase of snow thickness by 1 cm. Preheating the pavement in advance can not only avoid snow cover, but also save energy consumption by using intermittent power supply.
