Abstract

The invention provides an anti-icing push structure for a slope protection of an earth-rock dam in a high and cold region, which is characterized in that three anti-icing push structures, a solar control system and a wind control system are arranged along a dam slope at the upstream of a dam body, wherein the three anti-icing push structures are respectively a cast-in-place concrete structure paved at the bottom and the top of the dam, a reinforced concrete wall body poured at the slope of the dam and an anti-icing push structure poured at the slope of the dam, reinforcing steel bars are embedded at the top of the reinforced concrete wall body, a novel heating material is fixedly arranged on the surface of the top of the reinforced concrete wall body, the anti-icing push structure is of a reinforced concrete structure, and the solar control system and the wind control system are in an exchange type working mode. The invention has the beneficial effects that: the invention achieves the frost heaving prevention effect by utilizing different structural forms, frost heaving prevention concrete and heating structures, and has the characteristics of strong ice pushing and pulling prevention capability, good frost heaving prevention effect and the like compared with the conventional frost heaving prevention structure of the earth-rock dam. The invention also provides a construction method of the ice pushing preventing structure for the slope protection of the earth-rock dam in the alpine region.
