Abstract:
A method and device for freezing the ground are disclosed, including a freezing lance which extends along a longitudinal axis and has a pipe mantle that encloses an interior space, wherein the ground surrounding the freezing lance can be cooled by the refrigerant present in a first section of the interior space, a line for supplying the liquid refrigerant in the first section of the interior space, wherein the device has a first end section with a first opening for removing an exhaust gas formed by evaporation of the refrigerant from the interior space, wherein the interior space has a second section for holding the exhaust gas, wherein heat is exchangeable between the exhaust gas and the pipe mantle in the second section, so that the exhaust gas can be heated by heat exchange with the ground adjacent to the freezing lance.

Claim (Index 12):
The method according to  claim 5 , wherein the refrigerant is stored in a refrigerant container in the event of overpressure, and wherein the refrigerant is introduced into the first section of the interior space from the refrigerant container, and wherein the exhaust gas is drawn out of the interior space through the first opening by a pressure differential between the interior space and an ambient atmosphere around the freezing lance which is in fluid communication with the first opening.
