KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der Erfindung bildet ein Gefrierrohr, das zur Herstellung einer Frostmauer beim Schachtbau und dergl. dient. Die Erfindung kennzeichnet sich dadurch, daß das S Innenrohr a, durch das die Gefrierflüssigkeit nach unten geführt wird, mit einem besonderen Mantel b umgeben ist? Infolgedessen wird das Innenrohr α gegenüber dem Außenrohr c isoliert, so daß es von der in diesemThe subject of the invention is a freezing pipe which is used to produce a frost wall when building a shaft and the like. The invention is characterized in that the S inner tube a, through which the freezing liquid is passed down, is surrounded by a special jacket b? As a result, the inner tube α is isolated from the outer tube c , so that it is of the in this

ίο eintretenden Temperaturerhöhung nicht beeinflußt wird. Dadurch wird ein Wärmeaustausch zwischen den beiden entgegengesetzt beweglichen Flüssigkeitssäulen vermieden, so daß die Kälteflüssigkeit unten beim Austritt aus dem Innenrohr in das äußere Rohr fast die gleiche Temperatur wie oben beim Eintritt hat, wodurch besonders in den unteren Gebirgsschichten eine bessere Gefrierwirkung erzielt wird.ίο the temperature increase that occurs is not influenced will. This avoids an exchange of heat between the two oppositely movable columns of liquid, see above that the cold liquid is almost at the bottom as it exits the inner tube into the outer tube has the same temperature as the entry above, which is particularly important in the lower one Mountain strata a better freezing effect is achieved.

Patent-Anspruch:Patent claim: Gefrierrohr, dadurch gekennzeichnet, daß das Innenrohr (a) von einem besonderen Rohr (b) umgeben ist, durch welches ein Isolierraum zwischen dem die Kälteflüssigkeit nach unten führenden Rohre (a) und dem die Kälte nach außen abgebenden Rohr (c) hergestellt ist, um eine Temperaturerhöhung der Kälteflüssigkeit durch Wärmeaustausch zu verhindern und dadurch eine bessere Gefrierwirkung, besonders in den unteren Gebirgsschichten, zu erzielen.Freezing pipe, characterized in that the inner pipe (a) is surrounded by a special pipe (b) , through which an insulating space is created between the pipe (a) leading the cold liquid down and the pipe (c) which emits the cold to the outside, in order to prevent an increase in temperature of the cold liquid through heat exchange and thereby achieve a better freezing effect, especially in the lower mountain layers.
