During the period, the ice layer can be adhered to the dam panel and the water stop, and when the water level of the reservoir area changes, the ice layer is displaced under the action of gravity, so that the frozen and adhered dam body surface, particularly a rubber water stop belt, is torn and damaged, the panel can be pulled seriously, and the safe operation of the dam is influenced; therefore, the ice melting or anti-freezing treatment needs to be carried out on the ice forming area of the dam surface in time.
At present, the more effective and feasible anti-icing method of the dam is mainly a pump type disturbance deicing method, which is mainly characterized in that a plurality of (dozens of) submersible pumps are arranged along the dam, each pump generates water flow disturbance at the contact position of the dam and the water surface at the depth of 0.5-1.0m, and the water temperature of the ice layer is obviously higher than the ambient air temperature, so the method can easily achieve the aim of preventing the dam surface of the area where the pump is positioned from icing or deicing.
However, after the reservoir water level changes, the pump diving depth cannot be automatically sensed and adjusted, the pump diving depth is too deep, so that the water surface disturbance is not obvious, and the pump is easy to heat and burn or form local jet flow without disturbance due to too shallow, so that the effect is reduced; on the other hand, the junction of the cable for fixing the submersible pump and the water surface is easy to freeze, so that the submersible pump needs to be manually adjusted after first breaking ice when adjusting the submersible depth, and the workload is large and the danger is high when multiple pumps are processed in batches.
