Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of highway pavement, specifically to a slope run-off ice protection structure suitable for plateau highway. BACKGROUND

[0002] Run-off ice is a phenomenon that in cold seasons, in plateau areas with large diurnal temperature difference, widely distributed frozen soil and complex hydrogeological conditions, when the underground water or surface snowmelt water in the slope range flows, it gradually freezes under the influence of low temperature, forms thin layer of ice at the initial stage, and then thickens and spreads with continuous low temperature and water supply, and even extends to the road surface, which reduces the road friction coefficient and threatens the driving safety, and also damages the highway slope structure due to freeze-thaw cycle, causing slope instability and other diseases.

[0003] In plateau areas, highway construction and maintenance face special natural environmental challenges, and run-off ice phenomenon is one of the important problems affecting highway traffic safety and service life. Run-off ice mainly forms in cold seasons. Due to large diurnal temperature difference, widely distributed frozen soil and complex hydrogeological conditions in plateau areas, the underground water or surface snowmelt water in the slope range gradually freezes during the flow process due to the decrease of external temperature. At the initial stage, thin layer of ice may be formed on the surface of the slope. With continuous low temperature and continuous water supply, the ice will gradually thicken and spread, and even extend to the road surface to form run-off ice. However, the run-off ice covering the road surface will significantly reduce the road friction coefficient, causing vehicle skidding and seriously threatening driving safety. Moreover, the repeated freeze-thaw cycle of run-off ice will damage the highway slope structure, causing slope frost heaving, thawing and sinking, and further causing slope instability, collapse and other diseases, increasing the highway maintenance cost. At the same time, the traditional protection measures mainly focus on single drainage or heat preservation, which is difficult to adapt to the complex geological and climatic conditions in plateau areas, and has the problems of limited protection effect and insufficient durability.
