Technical Field
The invention relates to a device for preventing rockfill dam panels in alpine and high-altitude areas from being damaged by freezing and melting. Is suitable for the field of water conservancy and hydropower engineering.
Background
At present, the face rockfill dam is a dam body structure widely adopted in the field of domestic and foreign water and hydropower engineering construction, and in high-cold high-altitude areas, the freezing period is long due to high altitude and low air temperature. In the freezing period, freezing causes freeze-thaw damage to the concrete surface of the dam panel and frost heaving damage inside the concrete panel and extrudes and ices the water stop structure on the surface of the panel joint to damage, so that the safety of the dam structure is influenced, a large amount of manpower and material resources are required to be invested for maintenance in the later period, the engineering benefit and safety are influenced, and the problem of freeze-thaw damage of the dam panel must be solved by adopting special equipment.
The freeze-thaw damage is mainly caused by icing due to too low water temperature under low temperature conditions, so that the problem of freeze-thaw damage is solved by preventing the icing on the surface of the rockfill dam facing in winter. In the early stage, a plurality of management organizations adopt measures such as electric heating or manual ice chiseling to prevent the icing of the water area in front of the dam, but the implementation effect is not ideal.
