Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es ist bekannt, zum Abteufen von Schächten in schwimmendem Gebirge Bohrlöcher vorzutreiben und durch diese Druckluft in das schwimmende Gebirge einzuführen, so daß eine Entwässerung des letzteren bewirkt wird und das weitere Abteufen in trockenem Gebirge geschehen kann. Zur Verdrängung des Grundwassers bei Ausschachtungen für Grundbauten wird nach vorliegender ErfindungIt is known to drive boreholes to sink shafts in floating mountains and through this to introduce compressed air into the floating mountains, so that drainage of the latter is effected and that further sinking can take place in dry mountains. To displace the Groundwater in excavations for foundation structures is made according to the present invention

ίο gleichfalls Preßluft in den Baugrund durch zahlreiche in die Baugrube und um sie herum angeordnete Rohre eingeführt, und zwar ohne daß Spundwände, Kästen oder sonstige Vorrichtungen üblicher Art zur Umschließung der Baugrube verwendet werden. Die Preßluft bildet dann ein vollständiges Luftpolster, das dammartig das Nachdringen des Grundwassers in die durch Auspumpen trockengelegte Baugrube verhindert. Zu diesem Zwecke werden in den Seitenwänden und der Sohle der Baugrube die Rohre so angeordnet, daß ihre Wirkungskreise sich schneiden und somit die um die Baugrube zu bildende Luftschicht eine lückenlose Wand bildet.ίο also compressed air into the subsoil numerous pipes arranged in and around the excavation, namely without sheet piling, boxes or other devices of the usual type for enclosing the excavation can be used. The compressed air then forms a complete air cushion, the dam-like penetration of the groundwater into the drained by pumping out Excavation prevented. For this purpose, the pipes are arranged in the side walls and the base of the construction pit in such a way that that their spheres of activity intersect and thus those to be formed around the construction pit A layer of air forms a gapless wall.

Dieses Verfahren ist bei Baugruben, senkrechten, wagerechten und geneigten Schächten, Tunneln und ähnlichen Bauwerken anwendbar. This method is suitable for construction pits, vertical, horizontal and inclined shafts, Tunnels and similar structures applicable.

' Die Rohre für den Einlaß der Preßluft können entweder auf einer Seite oder auf dem ganzen Umfange mit Löchern versehen sein.The pipes for the inlet of the compressed air can either be on one side or on the be provided with holes over the entire circumference.
