Express highway snow melting method

Abstract

The invention discloses a snow melting method for an expressway. The central isolation belt or two sides of the expressway is / are provided with a water pumping device which is connected with a spray appliance which comprises a water pump, a water pipe connected with the water pump, and a nozzle arranged on the water pipe. Wells are built at the central isolation belt or the two sides of the expressway. When it snows, underground water is pumped out by the water pumping device, and the water is transferred to the spray appliance which uniformly sprays the water to cover the road surface, so that the snow is melted by using the underground water. The method is capable of melting snow at quick snow melting speed, without closing down the expressway, without damage on the road surface and without harm to plants and crops at the two sides of the expressway. The method is exceedingly environment-friendly and favorable for being popularized and applied.

Description

1. Technical field [0001] The invention relates to a technical solution for ensuring the smooth flow of highways in severe winter weather, in particular to a method for melting snow on highways. 2. Background technology [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 my country, which has greatly affected the opening of expressways. In order to recover as soon as possible, the management department often uses machinery and salt to remove snow. Especially the use of deicing agent provides convenience to the management department, but after the snowy day, the side effects of deicing agent cannot be underestimated. [0003] 1. The farmlan...

[0006] 2. Shorten road life

[0007] Especially on asphalt concrete pavement, salt substances and asphalt will produce chemical reactions, which will greatly reduce the gripping ability of asphalt materials and sand and gravel materials, causing the asphalt surface to fall off, and the pavement will be damaged in large areas under the action of traffic load; After flooding, salt rise will occur, which will cause damage to the road subgrade and directly cause the road to die, which will greatly increase the difficulty of road maintenance in the later stage; salt also has harm to cement concrete pavement, the reason is very simple, urban roads High cost salt-resistant cement will not be used on the side of the cement concrete pavement

[0008] 3. Pollution of the environment

After the salt substances enter the ground, they will inevitably pollute the local groundwater resources, and eating water polluted by deicing agents will cause serious harm to human health
