Description

Verfahren zum Verschließen des Kernrohres Zusatz zum Patent 592 359 Nach dem Patent 592 359 soll das Kernroh, mittels einer Klappe, die durch ein Gestänge betätigt wird, geschlossen werden.Method for closing the core tube Addendum to patent 592 359 According to patent 592 359 the core tube is to be closed by means of a flap which is operated by a rod.

Da diese Einrichtung infolge ihrer beweglichen Teile #umständlich und bei schlechtem Untergrund schwierig zu handhaben ist, wird gemäß derErfindung dasVerschließen desKernrohres dadurch bewirkt, daß in dem unteren Ende dieses Rohres ein Gummischläuch ringförmig angeordnet wird, der sich durch Aufblasen,lehnt und hierbei das, untere Ende verschließt. Die im Kernrohr befindliche Bohrprobe wird durch den aufgeblasenen Gummischlauch so zusammengepreßt, daß die Bohrprobe am Ausfließen verhindert wird und sicher aus dem Untergrund heraufgeholt werden kann. D as Aufblasen des Gummischlauches geschieht am zweckmäßigsten durch Luft, die mittels einer Zuleitung, die in dem Raum zwischen Außenrohr und Kernrohr ,angeordnet ist, unter Druck zugeführt wird.Since this facility is cumbersome due to its moving parts and is difficult to handle when the ground is poor, according to the invention the closing of the core tube is effected by being in the lower end of this tube a rubber hose is arranged in a ring, which is inflated, leans and this closes the lower end. The drill sample located in the core tube is compressed by the inflated rubber hose so that the drill sample flows out is prevented and can be safely brought up from the underground. The inflate of the rubber hose is most expediently done through air, which is supplied by means of a supply line, which is arranged in the space between the outer tube and the core tube, is supplied under pressure will.

Die Erfindung ist auf der beiliegenden Zeichnung beispielsweise veranschaulicht. In dem Zwischenraum zwischen Pfahlrohr a und Kernrohr b ist die Zuleitung c angeordnet. Wird Luft eingepumpt,- so bläht sich der Gummischlauch d auf und preßt hierbei die im Kernrohr befindjiche Bohrprobe e zusammen.The invention is illustrated by way of example on the accompanying drawing. The supply line c is arranged in the space between the pile tube a and the core tube b. If air is pumped in, - the rubber hose d inflates and presses the drill sample e located in the core tube.
