Reservoir dam anti-freezing structure in cold region, and construction method of reservoir dam anti-freezing structure
The invention provides a reservoir dam anti-freezing structure in a cold region, and a construction method of the reservoir dam anti-freezing structure, and belongs to the technical field of reservoirdam anti-freezing. The dam anti-freezing structure comprises a dam body and a plurality of gravity assisted heat pipes; the dam body is provided with an upstream face, and the gravity assisted heat pipes are arranged on the dam body at intervals along a bank of the dam body; each gravity assisted heat pipe comprises an evaporation section located on a lower portion and a condensation section located on an upper portion. By means of efficient heat transfer characteristics of the gravity assisted heat pipes, the dam body below the reservoir water and reservoir water heat can be transferred to the upper portion of the dam body in the cold season, freezing of the dam body is effectively prevented, safe operation of the reservoir dam in the cold region is guaranteed, and the service life of the dam body is prolonged.
本申请提供了一种寒区水库大坝防冻结构及其施工方法，属于水库大坝防冻技术领域。大坝防冻结构包括坝体和多个重力热管。坝体具有迎水面，多个重力热管沿坝体的沿岸间隔布置于坝体。重力热管包括位于下部的蒸发段和位于上部的冷凝段。通过重力热管的高效传热特性能够在冷季将库水下部坝体及库水热量传递至坝体上部，有效防止坝体的冻结，保障了寒区水库大坝安全运营，延长了坝体的使用寿命。
