Abstract

The invention discloses a wall freezing device and method applicable to freezing of a stratum. Multiple freezing holes are formed in the stratum. The wall freezing device comprises multiple freezing units. Each freezing unit comprises a Stirling refrigerator which comprises a refrigeration end. A freezing barrel is arranged at each refrigeration end. The Stirling refrigerators refrigerate the freezing barrels through the refrigeration ends of the Stirling refrigerators. When a freezing wall needs to be formed, the freezing barrels are inserted into the freezing holes. By means of the technical scheme, installation is easy and convenient, design is convenient, the application range is wide, the freezing efficiency is high, the freezing effect is good, and pollution is avoided.

Description

technical field [0001] The invention belongs to the field of machinery and relates to a freezing wall device, in particular to a Stirling freezing wall device and method. Background technique [0002] Frozen walls begin with foundation pit construction under the cover of permafrost structures frozen by artificial techniques. Before construction, use artificial refrigeration technology to freeze the unstable formation or aquifer around the wellbore into a closed frozen wall to resist ground pressure and isolate groundwater. In the prior art, a frozen wall is also used to form a shield to prevent moisture from penetrating into the formation. [0003] In order to form the freezing wall, a certain number of freezing holes need to be drilled, and a freezer is installed in the holes. The low-temperature brine produced by the freezing station is sent to the freezer through pipelines. After the low-temperature brine circulates in the freezer, it returns to the freezing station to ...
