Abstract (en)
The invention pertains to device for and a method of inserting a drainage material (5), such as a drainage wick, into the ground, said device comprising a carrier (1) or frame, an insertion lance (3) comprising a passage for receiving the drainage material (5), and a means (2) for guiding the lance. The lance comprises a bottom portion (11) which, seen in the insertion direction of the lance, has a cross-sectional area smaller than that of the adjoining portion (13) of the lance. The resistance acting on the lance during insertion thus can be reduced considerably. <IMAGE>
