Title

Verfahren zur Rodung von Baeumen

Other Title
Tree uprooting method uses high pressure water jet directed into ground at required angle for separating root ball from surrounding earth.
Abstract
Die Erfindung betrifft ein Verfahren zur Rodung von Baeumen mit mindestens einer Duese fuer einen Hochdruckwasserstrahl mit zugesetztem Abrasivstoff und einer Fuehrung, an der die mindestens eine Duese angeordnet und auf einer Umfangslinie um einen Baum bewegbar ist. Die Duese ist in ihrem Neigungswinkel veraenderbar und feststellbar.

DE 10032359 C UPAB: 20011203 NOVELTY - The tree uprooting method uses a high pressure water jet (11), in which an abrasive material is mixed with the water, directed into the ground at a given angle to the vertical over a defined area around the base of the tree (1). The penetration depth of the water jet is selected so that the full root ball (2) of the tree is separated from the earth, to allow removal of the tree complete with its root ball. USE - The method is used for uprooting of a tree complete with its root ball to allow replanting. ADVANTAGE - The method allows the penetration depth of the high pressure water jet to be adjusted in dependence on the size of the tree, for ensuring that the root ball is not damaged.
