Description
Technical field
The invention belongs to technical field of fixed buildings, relate to a kind of road surface and job practices thereof, facility and the job practices thereof of initiatively defending road, bridge, a road ice and snow disaster particularly used on a kind of road or bridge or the road.
Background technology
Along with the weather on Earth cyclically-varying, the every interval of EI Nino phenomenon all exceedingly odious meteorology will occur in 4 years.Abominable natural climates such as high temperature and drought, heavy showers, typhoon, strong cooling, ice and snow disaster, sleet seriously affect human normal life.In the warm band of southern china, the southeastern coastal areas strong cooling, snowfall repeatedly appear in recent years, highway freezes and causes pernicious traffic accident to take place frequently, car crash, loss of goods, stop up a large amount of vehicles, personnel are stranded in the road surface, cause tremendous economic loss and bad social influence.
1., highway, bridge, a channel temp periodically be lower than 0 ℃ the fundamental that forms the ice and snow disaster has:; 2., natural precipitation, snowfall; 3., artificial watering.
