Research and Application of the Local Differential Freezing Technology in Deep Alluvium

Figure 9

Variation of temperature in different regions for the conventional freezing method and local differential freezing technology (the minimum temperature of the efficient freezing and limited freezing parts of the local differential freezing pipe was −28.6 and −13.5°C, respectively). (a) Temperature curve at the measurement point C5. (b) Temperature curve at the measurement point C2. (c) Temperature curve at the measurement point C1.
