针对新型道路热融雪过程,开展三种不同埋管节距道路实验。研究主动融雪过程中道路热融雪特性和路面融雪形态和传热规律,分析道路路面温度、单位面积耗热量和单位流程温差的变化规律,探索融雪过程因素影响特征,认知道路埋设盘管热流体循环融雪过程。实验研究表明:积雪和降雪的融化过程分为四个阶段,由于埋管节距的不同,密距型道路在四个阶段所需时间最少;同时,埋管节距越小,其表面无雪率越大,融雪能力越强,单位面积耗热量也越大,但单位流程温差存在一定的增长限度。
For the new road hot snow melting process, three different pipe pitch road tests were carried out. The characteristics of hot melt snow and snow melt morphology and heat transfer during active snow melting were studied. The variation of road surface temperature, heat loss per unit area and unit process temperature were analyzed to explore the influencing characteristics of snow melting process. Cyclic snow melting process. Experimental studies show that the melting process of snow cover and snowfall is divided into four stages. Due to the different pitch of buried pipes, the minimum time required for the dense-type road in the four phases is the minimum. At the same time, the smaller the pitch of the buried pipe, The greater the snow rate, the stronger the snow melting ability, the greater the heat loss per unit area, but the unit process temperature difference has a certain growth limit.
