A complete set of snow melting and deicing device for expressway road surface and deicing method thereof

Abstract

The invention discloses a piece of full-set equipment for deicing and melting snow on a highway pavement and a deicing method of the equipment. The full-set equipment comprises an impermeable liquid storage tank, a temperature sensor, a humidity sensor, a snow depth sensor, an ice thickness sensor, a liquid level sensor, a control switch device, a liquid pump, a regulating device, an external power supply, and a connector. The equipment is arranged about five meters lower than the pavement on the two sides of a highway, the temperature and the humidity of the surface of the highway are detected through the temperature sensor and the humidity sensor, the control switch device starts the liquid pump, an antifreezing solution is pumped into the pavement through an anticorrosion steel tube, circulates and flows, and transfers the absorbed heat to the pavement, so as to fulfill the purpose of deicing and melting snow. By using the full-set equipment and the deicing method, the clear road and the driving safety are effectively guaranteed, the traffic accidents caused by freezing the accumulated snow on the pavement are reduced, and the casualties and the economic losses are reduced.

Description

technical field [0001] The invention belongs to the technical field of highway engineering in traffic and transportation engineering, in particular to a complete set of snow-melting and deicing equipment for expressway pavement and a deicing method thereof. Background technique [0002] Snow and icing on the road has become a worldwide problem. The snow and icing on the road has a serious impact on the safety of expressway driving. In January 2008, southern my country suffered from rare extreme weather of low temperature, rain, snow and freezing, which closed most of the highways, airports and other roads in southern provinces such as Hunan, Guizhou, Anhui, Jiangsu, Jiangxi, etc., causing economic losses reaching several 10 billion. The impact of snow and icy roads on traffic is obvious. Snow accumulation and freezing in cold areas will not only often lead to the closure of expressways or airports, which will have a great impact on the national economy and people's lives, b...

Problems solved by technology

[0004] The disadvantage of manual snow removal is that it is inefficient, time-consuming and labor-intensive, and it needs to be closed to interrupt the traffic, which has a large lag and cannot open the traffic in time, which affects traffic capacity and safe driving

The disadvantage of mechanical snow and ice removal is that it needs to be closed to interrupt traffic, which has a certain hysteresis. Under low temperature conditions, the snow on the road cannot be completely removed, and a thin layer of ice often appears on the road surface, which affects the safety of road driving. Imported) Only a few cities such as Harbin, Shenyang, Urumqi, etc., have almost no snow removal machines in other cities, which is uneconomical

Sprinkling industrial salt or other salt deicing agents is the most common way to remove ice and snow, but spreading industrial salt or other salt deicing agents will seriously corrode pavement materials, underground steel bars and pipelines, and at the same time damage the transportation infrastructure and surrounding soil, The growth of plants has brought serious harm, increased repair costs, and huge economic losses

The deicing and snow removal measures that are still in the research stage are mainly to heat up the pavement materials in various ways to prevent the snow on the road from freezing. , the pavement heating material will be destroyed and must be rearranged, resulting in a large waste
