Expressway dripping type snow melting device and snow melting method

Abstract

The invention provides an expressway dripping type snow melting device and a snow melting method. The device comprises a main water pipeline laid in a greening isolation belt in the middle of an expressway in the longitudinal direction of the expressway. The water inlet end of the main water pipeline is connected with a reservoir for taking water through urban reclaimed water; a plurality of waterdiversion pipelines are uniformly arranged on the main water pipeline; one ends of the water diversion pipelines extend out of a middle greening belt protective fence of the greening isolation belt in the middle of the expressway and are arranged at the upper part of the expressway pavement; water dripping heads are connected to the water diversion pipelines; and water dripping openings of the water dripping heads are downward, so that a snow-melting agent passing through the main water pipeline and the water diversion pipelines is dripped on the high side of the expressway pavement and transversely flows from the expressway into a drainage channel on the low side of the expressway pavement. The expressway dripping type snow melting device saves manpower and financial resources, is low ininstallation and laying cost, cannot influence the expressway subgrade, melts ice and snow on the expressway in a dripping mode, avoids the influence of snow melting in an injection mode on running vehicles, and reduces safety accidents.

Description

technical field [0001] The invention belongs to the technical field of road snow melting, and in particular relates to a trickle-type snow melting device and a snow melting method for expressways. Background technique [0002] With the development of the economy, the mileage of expressways in my country has leapt to the forefront of the world, forming a criss-cross expressway network. Due to the geographical location of our country, most of the country’s area has heavy snowfall in winter, especially In recent years, due to changes in the global climate, heavy snow and blizzards have occurred frequently in our country, which has greatly affected the opening of expressways. In the case of heavy rain and snow on the expressway, the road surface is easy to freeze. The icy road section greatly reduces the friction coefficient of the vehicle. Once an emergency occurs, the vehicle is easily out of control and causes heavy casualties and property losses. Therefore, for the problem o...

Problems solved by technology

In the case of heavy rain and snow on the expressway, the road surface is easy to freeze. The icy road section greatly reduces the friction coefficient of the vehicle. Once an emergency occurs, the vehicle is easily out of control and causes heavy casualties and property losses.

Therefore, for the problem of expressway icing in snowy days, the measures generally taken now are: first, the management department stops the operation of the ice and snow section of the expressway, which causes great inconvenience to our country's traffic and seriously affects traffic operation; second, uses vehicles to scatter snowmelt There are two methods of deicing agent and mechanical deicing for snow removal. These methods have low anti-icing and snow melting efficiency and heavy workload, which will still affect normal traffic operation; the third is the patent No. The document discloses a method of melting snow, by setting water pumping equipment on the green belt or both sides of the expressway, and connecting spraying equipment, including a water pump, a water pipe connected to the water pump, and a sprinkler installed on the water pipe, to green the middle of the expressway Drill water wells in the isolation zone or on both sides. When it snows, use pumping equipment to pump groundwater, and then send the water to spraying equipment to evenly spray the well water to cover the road surface, and use the groundwater temperature to melt snow. Installing pumping equipment requires a lot of manpower and financial resources, and the production cost is high. Moreover, drilling wells on both sides of the expressway will affect the roadbed of the expressway. In addition, this patent adopts the method of spraying to melt snow, and the snow-melt water is sprayed during the spraying process. , the height of the spraying is high, which will affect the vehicles running on the expressway
