Cold region earth-rock dam anti-frost-heaving structure and construction method thereof

Abstract

The invention provides a cold region earth-rock dam anti-frost-heaving structure and further provides a construction method of the cold region earth-rock dam anti-frost-heaving structure. A slope protecting structure and a novel anti-frost-heaving structure are arranged along the upstream dam slope. The slope protecting structure comprises cast-in-place concrete structures, sand gravel cushion layers and geomembranes which are laid at the dam bottom and the dam top correspondingly. The novel anti-frost-heaving structure comprises a tempered glass heating plate, a photovoltaic cell panel, an LED light-emitting indicator layer, a solar charger, a storage battery, light-controlled heating switches, a basic stratum, a reinforced concrete wall and pre-embedded steel bars. The cold region earth-rock dam anti-frost-heaving structure has the beneficial effects that the novel anti-frost-heaving structure is utilized for heating and warning to achieve the anti-frost-heaving effect, and comparedwith a conventional earth-rock dam anti-frost-heaving structure, the characteristics of good anti-frost-heaving effect and the like are achieved.

Description

technical field [0001] The invention relates to the field of water conservancy and electricity engineering, and more specifically relates to an anti-frost heave structure of earth-rock dams in cold regions and a construction method thereof. The method is suitable for constructing earth-rock dams in cold regions. Anti-frost effect of earth-rock dams. Background technique [0002] Frost heaving failure of earth-rock dam slope protection is a common problem in water conservancy projects in alpine regions. The earth-rock dam slope protection will produce frost heave deformation and ice pull damage under the action of negative temperature in winter. In spring, the temperature rises to make it melt and cause thawing deformation. In spring, ice thrust is generated under the action of wind and waves. Earth-rock dam slope protection will cause damage. [0003] In the prior art, the anti-seepage and anti-frost heave structure is single, and the anti-frost heave effect is poor, and t...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the anti-seepage and anti-frost heave structure is single, and the anti-frost heave effect is poor. After repeated freezing and thawing, frost heaving, ice pushing and ice pulling, the slope protection of earth-rock dams will be damaged.

The anti-frost heave problem has not been solved fundamentally. After several freeze-thaw cycles and freezing damage, the earth-rock dam slope protection will be damaged by frost heave, which not only affects the operation efficiency of the reservoir but also increases the maintenance cost
