Abstract (en)
[origin: WO2009007760A1] The object of the invention is a group of methods for introducing small-diameter drainage pipes (2) into the ground in a given depth in radial directions starting from vertically arranged engineering structures (wells, soil penetrating lances, etc.) applied for soil and groundwater treatment, or for groundwater extraction or injection, said engineering structures being utilised as supporting structural elements (1). The methods are essentially characterised by that each drainage pipe (2) has a head portion (3) adapted for facilitating the insertion of the drainage pipe (2) into the targeted ground region (4), and by that the supporting structural element (1) comprises guide ducts (5) for guiding the drainage pipes (2), each duct having an arced section (6) guiding the drainage pipes (2) towards the ground. A given portion of the drainage pipes (2) thus introduced into the ground region (4) has perforations (9) or is otherwise made permeable, permitting that liquids or gases fed into the drainage pipes (2) may enter into (10) the soil of the ground region (4) through the permeable section. In case the drainage pipes are put under vacuum, liquids or gases may be extracted from the ground region (4) through the permeable section.
