This invention relates to a method for the stabilisation of slopes and/or terrain which are unstable or subject to landslides, by inserting suitable drainage devices. In particular, a vertical shaft with a concrete lining or a microtunnel (1) is constructed in an area of ground predefined by a suitable geological study, and an automated drilling unit (8) is positioned in the microtunnel or vertical shaft. Said drilling unit (8) comprises at least one drilling head (6), a magazine of rods (11), and robotic devices (13) able to pick up the rods (12) from the magazine and take them to said drilling head, said rods (12) being constituted by said drainage pipes (5); said head is then controlled to perform drilling operations, with simultaneous laying of the drainage pipe. In accordance with an advantageous aspect of the invention, said drainage pipes are constituted by a tubular steel element, the walls of which contain holes, each of which said holes houses a microfiltration valve. Said holes are filled with water-soluble material to prevent the passages from becoming obstructed during drilling; when the pipe has been laid, the water-soluble material dissolves, thus clearing said passages. |
