Description

The solar powered graphene heating film snow-melting system of highway and the highway for having the system

Technical field

The utility model relates to a kind of highway snow-melting systems.More particularly to a kind of solar powered graphene heating of highway Film snow-melting system and the highway for having the system.

Background technique

The quality of road surface situation is an important factor for influencing road traffic, in winter when asphalt concrete pavement is because of drop Snow and accumulated snow freeze when, bring serious influence to traffic safety and people's lives, or even cause huge economic loss.Mesh Salting (NaCl, CaCl is widely used in former world various countries₂) method of carrying out deicing or snow melting, seriously affect the resistance to of pavement of road bituminous sheaths The greenbelt of long property, road pavement facility and both sides of the road damages, and destroys surrounding ecological environment, therefore seek novel snow melt Change ice method to be of great practical significance.Highway and bridge are the important components of traffic transporting facility, for society It can play a crucial role with economic development into 2nd 1 century, global climate gradual warms up, worldwide extreme calamity Evil weather is more and more frequent；This brings huge pressure to the transport of China and energy network, constantly tests communications and transportation Safety, the most area of Northeast China, North China and northwest belongs to winter snow cover area, some traffic accidents and road product Avenge related, the communications and transportation of serious shadow noon and economic construction ice and snow on road surfaces problem have become puzzlement each department traffic management department Major issue, therefore research and develop scientific and effective road surface deicing and avenge technology, there is very important social effect and economic valence Value.A few years ago the whole country in especially big snowfall, to China especially southern area bring huge disaster, caused by direct economy Up to 53,700,000,000 yuan, countries in the world are to prepare equipment of sweeping away snow ahead of time according to weather forecast mostly when removing road ice and snow at present for loss With industrial brine or deicing salt, immediately to major trunk roads highway after snowing！Urban road is cleaned or is spilt deicing salt, by passively removing Snowization ice adversely affects to reduce；Artificial mechanism snow removing is time-consuming and laborious, and can destroy road using industrial brine and deicing salt！It is dirty Environment is contaminated, and there is anti-icing phenomenon.

Investigation shows that the quality of pavement behavior is an important factor for influencing road traffic, in cold winter, when pitch is mixed Solidifying soil surface is due to snowfall when accumulated snow icing, and road surface adhesive ability substantially reduces, dynamic property and safety pole to driving vehicle To be unfavorable, 15%~30% or so traffic accident is related with road snow in winter according to statistics.Serious road snow will be made At the closing of road, serious influence is brought to the coast is clear, or even cause huge economic loss.Such as member in 2008 Month, southern region of China meets with rare consecutive low temperature rain and snow weather, and highway, Trunk highway icy road are serious, cause National main line traffic is repeatedly interrupted, and passenger traffic is stopped transport.This time long-time, the low-temperature freezing rain and snow disaster of duration cause complete The highway communication in 23 provinces of state is influenced to different extents, 12 trunk lines of national expressways of the five national trunk highways running from north to south and seven running from west to east such as Jingzhu Highway In Dawu In more than totally 4 ten thousand kilometers, be up to 9 nearly 20,000 kilometers of many places sections are once forced close traffic.To the production and living of some areas Tremendous influence is brought, because of hundred billion yuan of calamity direct economic loss.

Bridge is in the hub site for connecting numerous roads, can be rated as " throat " of highway communication, simultaneously because bridge floor is complete Exposure is easier to freeze in air, than road surface, in addition bridge floor is narrow, many drivers drive to icing by no ice and snow road Bridge floor when, easily cause traffic accident and traffic jam due to underestimating to bridge floor driving difficulty, therefore bridge floor also becomes One of the keypoint part of domestic and international snowfall area snow cleaning and slipping preventing.

It can be seen that special road section region melting ice and snow heavier for traffic loadings such as road, bridges has been urgently to solve Realistic problem certainly.

There are mainly of two types for the method for winter deicing or snow melting both at home and abroad at present: removing method and melts method.
