Abstract

Bei einem Rammbohrgerät zum Herstellen oder Aufweiten von Erdbohrungen befindet sich in dem mit Düsen (17) ausgestatteten Gerätegehäuse (1) ein mit Hilfe von Druckluft axial hin- und herbewegter Schlagkolben (6,9) sowie ein Druckerzeuger (16), der die Düsen (17) mit einer Spül-, Schneid-, Schmier- und/oder Lenkflüssigkeit versorgt. Da der für den Abbau des das Gerät umgebenden Erdreichs und/oder der für eine Kurvenfahrt des Geräts erforderliche Flüssigkeitsdruck im Gerät selbst erzeugt wird, braucht das Gerät über eine Versorgungsleitung lediglich mit einer Flüssigkeit geringen Überdrucks versorgt zu werden.

Figure 00000001
In the case of a ram boring machine for making or widening earth bores, the device housing (1) equipped with nozzles (17) contains a percussion piston (6, 9) which is axially reciprocated with the aid of compressed air, and a pressure generator (16) which actuates the nozzles ( 17) supplied with a flushing, cutting, lubricating and / or steering fluid. Since the soil pressure surrounding the device and / or the liquid pressure required for cornering the device is generated in the device itself, the device only needs to be supplied with a liquid of low positive pressure via a supply line.
