Description

Die Erfindung betrifft ein Sprengverfahren zur Reinigung betonbehafteter Stahlrohre.The invention relates to a blasting method for cleaning steel pipes with concrete.

Diese Stahlrohre werden insbesondere bei der Bohrpfahlgründung verwendet.These steel pipes are used particularly in the foundation of bored piles used.

Bislang wurden die Rohre entweder nach mehrmaligem Gebrauch, und einer dem entsprechenden Betonanhaftung, verschrottet, oder in aufwendiger Arbeit mechanisch gereinigt.So far, the pipes were either after repeated use, and the corresponding concrete adherence, scrapped, or in laboriously mechanically cleaned.

Der Verfahrensablauf ist in der Zeichnung dargestellt.The procedure is in the drawing shown.
