建在粘土、含粘土、湿软泥或细沙地上的低温库之地坪冻鼓是可怕的,所造成的后果是极为严重的,常常导致冷库报废。安装保护装置可以防止冻鼓,至少可以减轻后果。精确掌握冷库地坪的温度分布情况对于设计适用的保护装置是完全必要的。过去,对其以大概地估计而安装的保护装置,在经济性、安全性方面是难以合理的。 Ping-pong drums built on low-temperature reservoirs of clay, clay, wet slime or fine sand are horrible and the consequences are extremely serious, often resulting in cold storage scrap. Installation of protective devices to prevent freeze-drying, at least to reduce the consequences. Accurately grasp the temperature distribution of the cold floor for the design of suitable protection device is completely necessary. In the past, it has been economically and safely impossible to justify the protective devices installed with a rough estimate.
