A Slope Protection Against Ice Pushing Damage

Abstract

The invention relates to a slope protection against ice push damage, which belongs to the field of water conservancy engineering. The slope protection includes slope protection stones composed of a water-facing surface and a back-water surface, and each slope protection stone constitutes a slope protection. The water-facing surface and the back-water surface are respectively made of black porcelain composite ceramics and concrete. Its water-facing surface is relatively smooth, impermeable and impervious to water, which prevents the ice body from being inlaid and occluded in the slope protection and cushion in cold regions, thereby avoiding the freezing and prying of the ice layer; The impact of pushing and destroying; the backwater surface is relatively rough, increasing the frictional force with the dam slope, which can make the backwater surface of the slope protection and the dam slope paved firmly, and ensure the stability of the slope protection. The slope protection against ice push damage described in the present invention can be adapted to the dam slope protection of the variable amplitude section of the water level of the reservoir area in cold winter, has low production cost, simple structure, and is convenient for large-scale factory manufacturing.

Description

technical field [0001] The invention relates to a slope protection technology in water conservancy projects, in particular to a slope protection for preventing river bank protection or earth-rock dam slopes from being damaged by ice pushing in cold regions, and belongs to the field of water conservancy projects. Background technique [0002] At present, the slope protection forms used in the slope engineering of earth-rock dams and river channel revetments usually include stone masonry slope protection, riprap slope protection and concrete face slope protection, etc.; and masonry slope protection is divided into mortar masonry slope protection and dry stone slope protection. [0003] The above-mentioned masonry slope protection and riprap slope protection are widely used in the slope engineering of the earth-rock dam or the bank protection engineering of the river channel, and the surface is not smooth enough, the surface flatness of the slope protection is very poor, and the...

AI Technical Summary

Problems solved by technology

Therefore, traditional masonry revetment and riprap revetment are not conducive to the protection and stability of river bank revetment and earth-rock dam slope in cold regions.

[0004] Although the slope surface of concrete face slope protection is better than that of masonry slope protection and riprap slope protection, its block face plate is too large to adapt to the uneven settlement of earth-rock dam body and bank slope soil, and it is easy to produce tensile cracks, resulting in The concentrated leakage of the dam body also endangers the safety of the dam; at the same time, there are natural gaps in the concrete face slope protection, the strength is limited, and it is easily damaged under the environmental conditions of frequent dry-wet alternation and freeze-thaw changes, so it is not suitable for long-term use in cold regions
