Unattended snow removal station for interchange ramps of expressway

Abstract

The invention provides an unattended snow removal station for an interchange ramp of an expressway. The unattended snow removal station comprises a liquid storage device, a power device, a liquid spraying device and a control device, wherein the liquid storage device is arranged near the ramp; a liquid inlet of the power device is communicated with the liquid storage device; a geothermal source heat exchange device is arranged in the liquid storage device in advance, a gravity heat pipe is adopted in the geothermal source heat exchange device, and the gravity heat pipe comprises a heat pipe evaporation section arranged underground, a heat pipe condensation section arranged in the liquid storage device and a heat pipe heat insulation section connected with the heat pipe evaporation section and the heat pipe condensation section. Energy consumption is reduced, and it can be guaranteed that no snow is accumulated in key areas such as hub intercommunication ramps at any time.

Description

technical field [0001] The invention relates to an unattended snow-removing station for expressway interchange ramps, and relates to the technical field of road and bridge construction and maintenance. Background technique [0002] The interchange of expressway hubs is the location where different expressways intersect. There is a situation where the turning radius of the interchange ramp is small, and the turning is quicker and is prone to traffic accidents. After snowfall occurs on the expressway, the expressway will generally be closed according to the snowfall conditions, and social vehicles will be prohibited from going on the road, and then the expressway maintenance work area will carry out snow removal operations. Driving, especially in the expressway hub interchange, the amount of snowfall is generally not closed. When social vehicles drive to the ramp with a small turning radius of the hub interchange, the snow conditions are slippery, which may easily cause the ve...

AI Technical Summary

Problems solved by technology

After snowfall occurs on the expressway, the expressway is generally closed according to the snowfall conditions, and social vehicles are prohibited from going on the road, and then the maintenance work area of ​​the expressway will carry out snow removal operations. For a period of time after the closure of the expressway, there are still social vehicles on the expressway that have not left the expressway Driving, especially the highway hub interchange, the general snowfall will not be closed. When social vehicles drive to the ramp with a small turning radius of the hub interchange, due to the slippery snow conditions, it is easy to cause the vehicle to lose control and cause traffic accidents

[0003] Therefore, according to the risk level, the snow removal priority of the hub interchange ramp is higher than that of the main line. To solve this situation, it is necessary to set up unattended snow removal stations at important ramps, and carry out snow removal operations by spraying liquid snow melting agents

[0004] At present, there are mainly two types of deicing agents used in the market, organic deicing agents and chlorine salt deicing agents. Organic deicing agents have no corrosive effect on infrastructure. Because the price is too high, they are only used in small quantities in airports, golf courses and other places; 1. Chloride salt deicing agents, such as sodium chloride, calcium chloride, magnesium chloride, potassium chloride, etc., are widely used in snow melting on highways, commonly known as "icing salt". 1 / 10 of similar deicing agents, but its corrosion to large public infrastructure is very serious, and the melted snow or ice turns into liquid, which flows into sewer facilities, farmland, etc., which is extremely harmful and endangers farmland and green belts. , shorten road life, pollute the environment and other issues
