Active anti-freezing concrete panel for rock-fill dam and pouring method
The invention provides an active anti-freezing concrete panel for a rock-fill dam and a pouring method of the concrete panel for the rock-fill dam. The concrete panel for the rock-fill dam comprises a panel body made of conductive concrete, and two electrodes electrically connected with an external circuit are arranged in the panel body; the panel body located between the two electrodes is provided with a shielding area, and the panel body is constructed to form current in an area located between the two electrodes and located outside the shielding area, so that the panel body is conducted with an external circuit, the heat loss of the heating layer is reduced while the mechanical property of the panel body is guaranteed, and the service life of the heating layer is prolonged. Therefore, the operation cost of the panel body is reduced, preheating before cold waves come is achieved, flexible power supply power is adopted according to the cold wave strength, freeze injury is relieved to the maximum extent, and safe and normal operation of a dam is guaranteed.
本公开提供一种主动抗冻的堆石坝用混凝土面板及堆石坝用混凝土面板的浇筑方法，堆石坝用混凝土面板包括采用导电混凝土制成的面板本体，面板本体的内部设置有与外部的电路电连接的两个电极，位于两个电极之间的面板本体设置有屏蔽区，面板本体被构造成在位于两个电极之间的、且位于屏蔽区以外的区域形成电流，使得面板本体与外部的电路导通，以达到保证面板本体的力学性能的同时降低了发热层的热损耗，从而降低了面板本体的运行成本，实现了在寒潮来临前提前预热，根据寒潮强度采取灵活的供电功率，最大程度的减轻冻害，保证了大坝安全正常运行。
