Long-term self-snow-melting method and system for road in winter

Abstract

The invention relates to a long-term self-snow-melting method and system for a road in winter. The long-term self-snow-melting method for the road in winter comprises the steps that heat-transfer vertical wells are arranged under an asphalt pavement or a concrete pavement and arranged in the positions, on the two sides of lanes, under the pavement of the road in a staggered mode with equal distances, and heat-transfer aluminum plate strips are arranged in the longitudinal direction of the heat-transfer vertical wells and fixedly connected with well lids of the heat-transfer vertical wells through bolts. According to the long-term self-snow-melting system for the road in winter, a heat-transfer snow-melting structure is arranged under the pavement and comprises the heat-transfer vertical wells and the heat-transfer aluminum plate strips; the heat-transfer vertical wells are arranged in the positions, on the two sides of the lanes, under the pavement of the road in the staggered mode with the equal distances; and the heat-transfer aluminum plate strips are arranged in the longitudinal direction of the heat-transfer vertical wells and fixedly connected with well lids of the heat-transfer vertical wells. According to the long-term self-snow-melting method and system for the road in winter, energy sources such as electric energy and devices such as a heat-exchange pump are not needed, the advantages of zero energy consumption, simple construction and long life are achieved, environment pollution is avoided, and economy and practicability are achieved.

Description

technical field [0001] The invention relates to a method and system for long-term self-melting snow on roads in winter. Background technique [0002] Snow and ice on the road surface in winter have brought serious safety hazards to the smooth flow of the road and the driving of vehicles. According to statistics, 30% of traffic accidents in winter come from the impact of road ice and snow. Therefore, the problem of road snow removal and deicing has become the focus of widespread attention in severe cold areas. At present, the methods of snow and ice removal in severe cold areas mainly include mechanical removal method and melting method. The mechanical removal method is suitable for large-scale mechanized removal operations, but it often needs to be completed after snow, which hinders traffic during the operation; after the road surface is icy, it is difficult to completely remove it; ice and snow removal machinery is greatly affected by the season, and the utilization rate...

Problems solved by technology

The chemical snow melting method mainly relies on chemical melting agents. This method has the characteristics of wide source of materials, cheap price, and good ice and snow melting effect. It was once widely used; however, chemical snow melting needs to be cleaned up later, and it will cause serious water resources and environmental pollution; in addition , the chemical deicing agent severely corrodes the steel bars and pavement, which reduces the service life of the bridge pavement

The hot melt method uses heating to melt ice and snow, mainly including cable heating, conductive concrete or asphalt, and circulating hot fluid methods; the main disadvantage of the hot melt method is that the cost of road construction increases, and the effect of snow melting and ice melting is not very ideal
