Three Times Pipe Freeze Wall Formation Properties In Trial Research

The design of frozen wall in deep alluvium is a difficult problem of freezing shaft sinking, at present, few research have reported in detail on the characteristic of frozen wall with loopy freezing pipe, not to mention the characteristic of its temperature field, moisture field and frozen-heave force of it. This paper analyzed the theory of temperature field and moisture field of frozen wall with loopy freezing pipe, adopted the model test method to simulate the characteristic of frozen wall with loopy freezing pipe : the forming characteristic in the temperature field which inside the frozen wall, the characteristic on moisture shifting which happened between two freezing pipe circle or two freezing pipe within the same pipe circle, the connection between...
